So VMware Virtual Volumes (VVols) is here, when will people start using it

VVols (1)

After many years in the making VMware’s new storage architecture, Virtual Volumes (VVols) is finally available as part of vSphere 6.0. VVols certainly looks cool but does the old adage hold true, if you build it will they come? In this post I’ll take a look at some reasons why people may want to wait to begin using VVols and some reasons why they might want to start using VVols right now.

Before we begin lets address what VVols is, VMware hasn’t stated this as far as I know but VVols will replace VMFS at some point. VMware never keeps two of any big infrastructure components around as it doubles their development work. They phased out ESX a few years after ESXi was launched, they just killed off their VSA in favor of VSAN and they are still trying to get rid of the vSphere Client in favor of the Web Client, at some point I expect them to phase out the Windows based vCenter Server in favor of the VCSA. So the same will most likely hold true with VVols, at some point VMware will phase out VMFS after it matures and more people start adopting it. Further evidence of this is that VVols is included in every edition of vSphere and it is not an add-on that you only get with certain editions.

Now lets first cover some reasons why you might want to wait before using VVols:

1. No support for storage array replication yet

This is a big one especially for larger enterprises that rely on storage array replication for BC/DR. Storage replication support is not part of the current VASA 2.0 specification so SRM and vMSC are not supported with VVols, for many that’s a show stopper right there. However despite VMware not supporting storage array replication yet some vendor implementations will or do support it now so that could be a workaround but you still can’t use it with SRM or vMSC until VMware builds it into the VASA spec.

2. It’s a 1.0 storage architecture

Yeah it’s been years in the making but it’s still 1.0 and like any 1.0 product there is always growing pains which could cause some people to wait. In addition there is still some feature and compatibility support missing in VVols (i.e. replication) which could prevent some people from adopting it right away. In addition on the storage array side support for it within the array which required a lot of development work from storage vendors is essentially 1.0 as well. A few storage vendors such as HP, NetApp and Dell were design partners and have been developing support for VVols for years so expect them to have the most mature implementations.

3. Not all storage vendors have full support for it yet

There were only a handful of companies (4) that had Day 1 support for VVols in the VMware Hardware Compatibility Guide, expect this to increase as more storage vendors finish their development work and complete the VMware certifications for VVols. In addition storage vendors are still working on broadening their supported features with VVols.

4. Who will win the data center politics game

Remember how it was when you first told your network admins about vSwitches and your networking requirements for vSphere. Yeah they felt they were giving up control and probably put up a fight. The same scenario might play out with VVols, storage admins may not like the fact that they are giving up some control and may push back on it. Resistance has proven to be futile though, the vSphere admins won the networking battle and they will eventually wear down the storage admins as well. To make this easier I encourage you to keep them fully involved, explain what VVols is and how it works and how it will ultimately make their job easier and allow for a much better relationship between VMs and storage.

5. How well does it scale

I have yet to see any performance numbers to show how well VVols does as it scales and a comparison to VMFS. Will it be better than VMFS, the same or worse? I expect it to at least be on par with VMFS, possibly even better, VVols isn’t really about boosting performance over VMFS, it’s about implementing a new VM-centric storage architecture that makes the VM a unit of storage to the storage array. The same held true with RDM’s vs. VMFS, it wasn’t about performance and VMware proved they performed equally as well so I expect the same to hold trued with VVols. It would be nice to have some testing though to back this up and I’ve heard that VMware is working on it.

6. Array features must be licensed

VMware has long tried to mimic storage array features inside of vSphere such as thin provisioning, VM snapshots, Storage vMotion, Storage I/O Control and more. Using many of those features on the vSphere side will not be possible any longer with VVols as everything shifts back to the storage array. So when you take a VM snapshot it will automatically be an array snapshot, same with using thin provisioning, the array will be doing it. This is a good thing as the array is better equipped to handle these functions faster and more efficiently. However this does require you to have those features licensed on your storage array to use them. Some vendors may include these features as part of their core feature set but others may not so check to see how much they will cost.

7. When will the backup vendors get on board

VVols changes the direct to SAN backup model as you now have a Protocol Endpoint and VASA Provider to deal with. I haven’t heard of any backup vendors that support this model with VVols yet but I expect to see support coming soon. Check with your backup vendors to see where they are at with VVol support and what there plans are for it. I expect to see Veeam be one of the first to support VVols as they tend to be ahead of the pack with supporting any new vSphere features.


This may seem like a lot of reasons to discourage you from jumping in and start using VVols but fear not, despite the reasons listed above VVols does provide some great benefits and is the right storage architecture for vSphere. Just like VSAN brings Storage Policy Based Management (SPBM) to the VM-level VVols does the same for shared storage. Aligning VMs directly to storage resources and having the storage array visibility to the VM-level is a very good thing to have. So lets now look at some reasons why you should start using VVols right now:

1. It’s not all or nothing with VVols

You can use VVols right along side of VMFS or NFS and you are not having to completely switch over to VVols all at once. VVols simply becomes another storage option that you can choose to put VMs on. You can easily move VMs from VMFS/NFS to VVols and back using Storage vMotion, so you can setup your Storage Container for VVols and then create or move VMs to it at your own pace.

2. Get early experience with VVols

Where you one of those last few people that made the switch from ESX to ESXi then had to struggle to learn the nuances of ESXi compared to ESX? Are you struggling with learning the vSphere Web Client? Why wait and have to learn how to use VVols when you are forced to do it as you have no other choice. Getting early experience and hands-on with VVols will get you ahead of the game and ensure you are ready when others are struggling to learn about it. You can also serve as a SME for VVols and help others learn it as well.

3. Get your disk space back!

This is big one, remember back in vSphere 5.0 when VMware introduced automatic space reclamation via UNMAP and then was forced to make it a manual process as it was causing some issues. They never did figure out how to make it an automatic process again until now, VVols is the answer. With VVols the storage array is VM-aware and knows when a VM is deleted or moved and can reclaim the disk space that it occupied right away. No more having to running a time and resource intensive process using esxcli to try and reclaim space, it’s automatic with VVols. If that wasn’t good enough on top of that UNMAP commands get passed from the guest OS to the storage array with VVols so you get even more granular space reclamation. This will ensure that you reclaim all capacity possible automatically and give you the best efficiency to maintain the smallest footprint on your storage array.

4. It’s available in all vSphere editions

Anyone can use VVols as long as your storage array supports it, there is nothing extra to license in vSphere. The setup for VVols is fairly easy as well so there is nothing stopping anyone from getting started with VVols right now.

5. Start using Storage Policy Based Management

Don’t get left out, get started using the same SPBM that VSAN users have been enjoying for the last year. SPBM allows you to define storage policies that are aligned to storage array capabilities that provide a whole new level of aligning storage array features and resources directly to VMs. SPBM allows you to pick and choose exactly what a VM should have from a storage perspective and it maintains compliance to ensure that the VM has whatever is defined in the storage policy. This is a powerful capability that VMware has put a lot of development effort in to make sure VMs have the best possible alignment with storage resources and that you can apply storage arrays features on an a la carte basis instead of at the large LUN level on many VMs.

6. Let the storage array do what it does best

The storage array is an I/O engine with software that is written specifically to work with that engine which makes it capable of powerful data movement and manipulation. Using VMFS and vSphere storage features you essentially have a 3rd party telling the array what to do which isn’t the best or most efficient way to do things. By letting the storage array do what it was designed to do without handicapping with a control freak that is pulling all the strings it allows for the array to do what it does best which results in the best possible efficiency. In addition array features are more powerful then comparable vSphere storage features and the array has better visibility into storage resources then vSphere has. As a results features like thin provisioning, snapshots and QoS are all more effective and efficient when done by the storage array.

7. Easier for the IT generalists

VVols ensures that IT generalists that may not have strong storage skills don’t have to be storage admins and can spend most of their time in the vCenter console instead of having to go to the storage console. With SPBM and VVols integration into vCenter you get a single unified management tool for storage that combines the best of both worlds, powerful storage array features managed directly from within vCenter.

8. One architecture to rule them all and in the darkness bind them

File or block? NFS, iSCSI, Fiber Channel, who cares? VVols provides a unified storage architecture across all storage protocols and puts them on a mostly level playing field with vSphere. With VVols you don’t have different types of files systems anymore, VMFS for block and NFS for file, you just have VVols and the various components that are universal to any storage protocol. Yes each protocol will still have some of it sown uniqueness still but VVols helps to eliminate some of that and make the protocol that is used less important.

8. The VM is a unit of storage

Saving the best reason for last, this is what VVols is all about, the storage array now has visibility to see individual VMs. With VMFS we only have visibility from the storage array at the LUN level, we could not see inside it and had no knowledge of the VMs that reside on that VMFS volume. Now with VVols that all changes, the VM is a first class citizen to the storage array and can be treated as a unit of storage. If we want to do an array snapshot on just one VM we can, with VMFS we had to take a snapshot of a whole LUN. If you want to assign QoS policies to certain Tier-1 VMs and not others you can, just about any storage array feature can now be done at the VM-level which is awesome. This eliminates the VMFS silo-ed approach which was wasteful and in-efficient from a storage array perspective. We can now provision storage only as needed without allocating huge chunks of it to VMFS datastores. This is the reason why VMware created VVols to begin with.


Everyone will have their own decision to make on when they want to get started with VVols, keep in mind at some point it will not be “if you will switch to VVols” it will be “when will you switch to VVols”. VVols certainly has some great benefits and better aligns storage resources to individual VMs but you will need to look how they fit into your own environment before making the decision to switch to them. I encourage you to get started as soon as you are able to, because you can use VVols alongside NFS or VMFS it makes the decision much easier as you can slowly dip into the pool instead of jumping all in.

vBlogger Spotlight: Eric Sloof

Spotlight-ES-crop


Top vBlog 2015 is over but I’m still continuing my vBlogger Spotlight series to shine the spotlight on several prominent bloggers in the community to give you some insight into their experiences with blogging. Today’s spotlight is on Eric Sloof, aka Mr. Scoop due to his keen ability to post news about VMware before anyone else is aware of it. Eric is another one of the OG bloggers as well as Godfather of the Dutch vMafia and also one of the hosts of VMworld TV that broadcasts live from VMworld events. Eric’s blog is NTPro.nl and has consistently been one of the Top 10 blogs. While other bloggers were all getting scooped up by VMware and it’s partners he’s chosen to remain as one of the few very independent bloggers left in the Top 25. Eric is one of the very early VMware Certified Instructors and remains one too this day. So without further ado enjoy a Q&A session with Eric Sloof:

What year did you start your blog?

[Eric] I’ve started my blog nearly 10 years ago. it was September 2005 to be more specific.

What inspired you to start a blog?

[Eric] The inspiration for my blog came from Mike Laverick – He was running the RTFM-Education blog for his own training company and I was really enjoying reading his articles.

Describe your early blogging experiences and how you have evolved over the years?

[Eric] My first blog articles were in Dutch and related to selling Vizioncore vRanger licenses. Back then I was the only reseller in Europe and my blog was used as part of my company ntpro.nl. When Vizioncore was going to an event or I was able to get a new customer, I posted an article about it.

After some time I switched to English and started blogging more about VMware. My first big event was the TSX in Nice 2007. I’ve covered that event with interviews, videos and photo’s. I think back then I was one of the first bloggers who was using multimedia to cover an event. I still have a picture of young Mike and me :-)

What has kept you blogging over the years and not quitting at it?

[Eric] At the start of 2007 I also became a VMware certified instructor. I kept on blogging because I’ve received a lot of positive feedback from my students and I’ve always used my blog as and extension of the training material. I was able to show an extra demo or screen dumps and dive a little bit deeper than the official material which resulted in good evaluation scores.

After all those years I’m still working as a trainer and I simply can’t quit as long as I experience the enthusiasm of my students.

What was your best experience or fondest memory related to blogging?

[Eric] The best experience because of blogging was being asked as a host for VMworld TV. Me and Jeremy are presenting VMworld TV for tree years in a row now and we’re doing both San Francisco and Barcelona. It’s so great to meet people worldwide who know you from your blog, just incredible. We had a lot of fun recording all the interviews and I felt as a big honour to be part of the VMworld TV crew.

Any advice for others who are new to blogging?

[Eric] My advice for people who are new in blogging is try to be unique. It doesn’t really matter if you’re doing one two or three posts a week as long as you have good content – content is king.

What Virtual Volumes does not support

VMware finally released the list of supported and non-supported vSphere features and VMware products with their new Virtual Volumes  (VVols) storage architecture. I’ve been looking for this in their documentation for VVols and have not found it so I’m glad to see it’s finally available so you can see exactly what is supported and more importantly not-supported that may impact your plans to deploy VVols.

Right now the one non-supported feature that sticks out and is a big one is storage array replication which is not part of the current VASA 2.0 specification. I’m not sure when VMware will support this, hopefully it will be soon as it currently limits VVols adoption. You will probably see storage array vendors supporting this on the array side before VMware supports it through their Storage Policy Based Management (SPBM) in vSphere. Note that while storage array replication is not currently supported vSphere Replication is as it is host based and sits above the VVols architecture. Also note though that while vSphere Replication is supported with VVols, SRM is currently not supported with VVols so it may be of little use to you.

Full-scale adoption of VVols will likely be slow in most shops as they both get experience with the new architecture and VMware along with storage array vendors improve feature support for VVols over time. But one thing to keep in mind when it comes to un-supported features with VVols its not all or nothing with VVols and you can continue to use VMFS right along side VVols to utilize features that currently are not supported such as FT and storage array replication. Also remember every vendors implementation of VVols is different and you should check with them to see what storage array features they support and do not support with VVols.

Below is the list of Not Supported features, expect this to shrink over time, be sure and check out the post on the vSphere blog for more details and the source for this information in the VMware Knowledge Base.

VMTurbo is giving away a great home lab just for watching a webinar

Register for the VMTurbo 5.1 Release Webcast and get THREE CHANCES to win a Turbostack Home Lab, valued over USD $1,600.00!

VMTurbostack-border

Now I would encourage you to watch the webcast even if they weren’t giving away a pretty cool home lab kit (that’s what they call it in the UK) as VMTurbo makes a great and unique product for vSphere environments. If learning about a great product wasn’t enough, you also have a chance to win something that you can try it out on. Their Turbostack Home Lab includes everything you need to get vSphere up and running including a host, external shared storage and networking to connect it all together. Below is what is included:

  • Intel NUC with Intel Core i5-4250U
  • G.SKILL Ripjaws Series 16GB (2x8G) 204-Pin DDR3 Memory
  • SAMSUNG 840 EVO 250GB SATA III TLC Internal Solid State Drive
  • Synology DS415+ Diskless System DiskStation 4-Bay NAS
  • 2x Dell 1TB 7200 RPM SATA 3.0Gb/s 3.5″ Hard Drive
  • Cisco SG300-10 10-port Gigabit Managed Switch
  • Rosewill 7ft. Cat 6 Network Cable

Now if you aren’t familiar with the Intel NUC, it stands for Next Unit of Computing and is designed to fit a lot of computing power in a small little package. This is great for a home lab as it requires very little space and both noise and power consumption (65w) are very low. You can read the specs for this cool little unit here.

The Synology DS415+ is a great mini storage array, I’ve owned a Synology unit and have always been impressed with them. It’s a very versatile unit that supports both iSCSI and NFS protocols and can be used for a variety of things beyond your vSphere lab. It holds up to 4 drives, supports SSDs and up to 24 TB (6 TB HDD X 4) of space.

So what are you waiting for, grab some popcorn and a beer, go watch the webinar, learn about a great product and maybe you walk away with some cool kit.

vBlogger Spotlight: William Lam

Spotlight-WL-crop


While we wait for the Top vBlog results I thought I would shine the spotlight on several prominent bloggers in the community to give you some insight into their experiences with blogging. Today’s spotlight is on William Lam, automation wizard extraordinaire and voted last year as the #2 vBlogger in the world. Let’s face it we all have a lazy side and automation makes an admins job so much easier. Thanks to William and his great tips and scripts we can all become big fat lazy vSphere admins. After all wouldn’t we rather be working smarter than working harder and the great content that William posts on his Virtually Ghetto blog makes that possible. William debuted at the #25 spot in the 2011 Top vBlog voting and quickly moved up into the top 10 in 2012 before rising to #2 last year. William is also a genius when it comes to nesting ESXi and getting ESXi to run on a Mac Mini to help out all those home labs out there. So without further ado enjoy a Q&A session with William Lam:

What year did you start your blog?

[William] virtuallyGhetto was started in 2010

What inspired you to start a blog?

[William] In the early days when I was a system administrator, I spent quite a bit of time on the VMTN Community Forums helping answer questions related to VMware automation and scripting. As part of my day job, I did a lot of Automation and I found that many of the questions that were being asked were things that I had done before or things that I was currently working on. I figured that I could help others by sharing some of the solutions and experiences that I had so that the greater community could benefit overall. With my replies, I usually ended up providing a fully functional script that exercised the task or operation so the OP gets the information they needed but also got a working example so that it helps them out in their current situation. All of this was done on the VMTN Community forum and some static HTML pages that I was manually updating which kept track of all the scripts that I had written. As you can probably guess, this made searching and notifications of new content pretty challenging.

I eventually decided to start a blog after multiple comments from my friend Duncan Epping who really encouraged me to give this blogging thing a try. He had always been a mentor/supporter of my content and had even blogged about my scripts on more than several occasions. I figured by having a blog, I could make it easier for people to search for solutions to their questions and help foster a community around VMware automation and scripting which did not really exist back then.

Describe your early blogging experiences and how you have evolved over the years?

[William] I had initially only focused on vSphere Automation as a topic for my blog. However, being a technologist and loving to learn about new things and solving problems I quickly expanded beyond just vSphere Automation. I started to explore other areas and products in VMware’s portfolio such as storage, networking and management. Other popular topics that I have been writing about are Nested Virtualization, Mac Mini for home labs and just doing cool and sometimes not supported things with VMware products. I definitely enjoy variety and you can see that with the content over the years.

What has kept you blogging over the years and not quitting at it?

[William] For me personally, it is the continue sharing of information with the community and the constant learning of new things that really keeps me going. I really enjoy learning about new technologies and in turn I can share that knowledge which can help someone solve a problem. You get this circular effect that only makes our community stronger.

What was your best experience or fondest memory related to blogging?

[William] Honestly, there are so many it is hard to just pick one. For me, the best experience I could get from blogging is just a simple note from a reader saying how one of my articles or a script has helped them solve a particular problem. I really do enjoy reading those emails and makes it all worth it at the end. I guess a nice runner up is hearing from VMware Engineering and GSS Support that they use several of my blog articles on a regular basis :)

Any advice for others who are new to blogging?

[William] Do not start a blog to just start a blog. Write about something that you are very passionate about. There are still so many topics within the VMware and Virtualization community that have been unexplored in great detail, try to really differentiate yourself from what others have already done. Lastly, it is all about the content! The more unique and interesting content that you can produce the larger the reward in terms of readership, engagement and longevity of blogging.

VMworld 2015 Call for Papers now open!

 

VMworldCFP-crop

It’s that time of year again, time to submit your best session ideas for VMworld for that oh so slight chance that it might get accepted. Below are the timelines for the whole CFP process.

  • Call For Papers opens March 24, closes April 28
  • June 12 (+/- a few days) Speaker Resource Center opens
  • June 23 Content Catalog goes live
  • July 14 (August 18 in Europe) Schedule Builder launches
  • 2 weeks prior to each show room assignments are announced

And of course some tips for making the best possible submission. From previous experience I can tell you to have a catchy title as it’s your sessions curb appeal. Many people won’t make it past your title and you miss a chance to interest them with your abstract if you have a boring and un-interesting session title. As a former content committee judge I can also tell you to spend some time on your abstract and don’t rush to throw something together without thinking it through. I’ve seen lots of session proposals that lacked any real detail about what the session was about. Here are some additional tips that VMware provides:

Tips for Creating Effective Titles for Submission

  • Do not use abbreviations or acronyms under any circumstances in the titles of your submissions.
  • Do not use competitor or other company names in your submission titles. If you are highlighting other companies within your session, you can adopt these names within the session description.
  • Start with the Benefit: Ex: Shorten Adoption Time by Using VMware’s XXX.
  • Use clear and concise language that attendees will immediately understand. The agenda will eventually host hundreds of sessions and attendees need to easily identify sessions of interest. Straight forward language like “Introduction to”, “Deep Dive” and “Case Study” are popular examples because they quickly tell the attendee important information about the session.

Typical Reasons for Abstract Rejection

  • The abstract is poorly written—ideas are not clear, goals are not established, there are grammatical errors, etc.
  • The content is not relevant to the indicated audience.
  • The session value is not clearly identified.
  • The session topic is not unique or overlaps with another more appropriate abstract.

Tips for Writing Winning Abstracts

  • Avoid beginning your session description with the phrase, “In this session we will…”, or “In this session you will learn…”. It does not add value and becomes tedious on an agenda of several hundred sessions. Instead try a rhetorical question, or an interesting industry data
    point to start your session abstract.
  • Ensure that what you submit will be what you present. Nothing will upset attendees more than signing up for a session that is not what it is advertised to be.
  • Your abstract should generate enthusiasm‐ make sure your content is relevant, but also generates excitement. What invaluable information will be shared during the session?
  • Thoughtfully leverage the tags in the system for topics, level, and roles. Who is the target audience? What products or topics does this session cover outside of the track name? What roles would specifically benefit from this session? Do not check every check box if your session is applicable to all.
  • Be Original – Attendees want to see new presentations that cover the latest innovations in technology. Take the time to create well‐written titles, abstracts, outlines, and the key takeaways for your submission. A thoughtful proposal will have a better chance of being
    selected and if accepted, will be seen by thousands of attendees once published in the course catalog.
  • Be Educational –VMware requires that sessions focus on the educational value of the presentation. Be sure that your proposal doesn’t sound like a sales pitch but rather an exciting opportunity for attendees to learn something new.
  • Be Timely – Make sure your topic is relevant to the audience you’re targeting. Review the content topics before submitting a session.

Upcoming round-table panel discussion on Virtual Volumes (VVols) hosted by Taneja Group

I’ll be participating as one of the panelists in an upcoming round-table discussion on Virtual Volumes (VVols) that is being hosted by Tom Fenton of the Taneja Group. Click the image below to sign-up and hope to see you there.

VMware Virtual Volumes – What impact will they have on the datacenter?

Thursday, April 2nd at 9:00 am PST

Join us for a fast-paced and informative 60-minute roundtable as we discuss one of the hottest topics in the datacenter: VMware vSphere Virtual Volumes (VVOLs). VVOLs is the industry’s first solution to enable native virtual machine-awareness across a broad range of SAN/NAS arrays. VVOLs will be packaged as a feature in VMware vSphere Standard Edition and above as well as in VMware vSphere ROBO editions, and is seeing a groundswell of interest from IT professionals, especially those involved in datacenter operations. The panel includes VVOL experts from four major vendors that have announced they will be implementing VVOLs into their storage. Some of the questions we will be asking them include: What immediate impact will VVOLs have on the datacenter? What should the early adopters look for in a VVOL-based storage solution? Should datacenters start to implement VVOLs right away or wait for VVOL.next?

When it comes to implementing Virtual Volumes (VVols) you better be on time

I was conversing with one of our VVol engineers today after he mentioned that we have seen customers experiencing problems with using VVols due to time sync issues in their vSphere environment. These problems could of easily been avoided with some simple RTFMing.

VMware’s New Virtual Volumes (VVols) architecture has a lot of moving parts and one big requirement for those parts to all work together is to have time synced between them. The below diagram depicts the vSphere components that are part of the VASA 2.0 specification which defines vendor VVol implementations.

VVOLs-arch

The vSphere 6 storage documentation states the following before implementing VVols:

  • Synchronize all components in the storage array with vCenter Server and all ESXi hosts. Use Network
    Time Protocol (NTP) to do this synchronization.

That means you must synchronize time across the same NTP source with every ESXi host that will use VVols, your vCenter Server, your storage array and your VASA Provider if its external and not built into the array. You might think that this is no big deal if you don’t do this but that’s not the case, here’s some scenarios where it will cause problems:

  • During the initial setup of VVols if the time between your vCenter Server and storage array are out of sync when you try and register your VASA Provider it will fail with a cryptic error message which won’t indicate that the failure was caused by time not being in sync..
  • Once you register your VASA Provider and try and use VVols if your ESXi hosts are out of sync as well you may not be able to create a VM on VVol storage. What could occur in this scenario is that the VVol datastore reports zero space available so you are unable to select it as storage device when creating a new VM. Again not something that you would attribute to time being out of sync.

There may very well be more issues with using VVols that occur due to time not being in sync between all components. There are also time stamps that are used with VVols that could potentially cause problems if the time is off. These issues may all not be obviously related to time so to save yourself from potential problems and troubleshooting just make sure you have all your clocks in sync.

vBlogger Spotlight: Mike Laverick

Spotlight-ML-border


While we wait for the Top vBlog results I thought I would shine the spotlight on several prominent bloggers in the community to give you some insight into their experiences with blogging. Today’s spotlight is on Mike Laverick, one of the OG bloggers who started his RTFM (Read The Frigging Manual) Education website way back in the early days of blogging. Mike was also one of the early book authors as a member of the Advanced Technical Design Guide rat pack that authored some of the first books on virtualization. Mike is the host of the Chinwag podcasts where he uses his laidback, informal interview style to chat with guests about virtualization. A former Certified VMware Instructor, Mike’s great passion for teaching and helping others is evidenced by his blog posts, articles, books, podcasts and his unselfish eagerness to share and give back to the community. So without further ado enjoy a Q&A session with Mike Laverick:

What year did you start your blog?

[Mike] RTFM Education started in 2003, but I flogged that to TechTarget, so I’m not sure if that really counts anymore! As for mikelaverick.com (such a pithy name dontcha think?) started in Feb, 2013…

What inspired you to start a blog?

[Mike] Back 2003 it was just an honest willingness to share what I learned, and help others. The plans for Dr Evil style world-domination came later…

Describe your early blogging experiences and how you have evolved over the years?

[Mike] I’m going to be a bit vain here. But I would like to my style has influenced others. I read other bloggers and think, “god, that’s just how I would do it”. I don’t feel ripped off, but slightly proud. I told you I was going to be vain! But I like to think my style is one that blends just right of theory with a big dollop of “getting it done”. My most popular posts have been ones that fix a commonly experience problem, that everyone runs up against in their time.

What has kept you blogging over the years and not quitting at it?

[Mike] Aside from a passion to share what I learn, I do generally love writing. I guess that comes from my liberal-arts background. You see I’m a bit of interloper who’s technical knowledge wasn’t gained through academic qualifications but via combo of experience, and training courses. One day someone is going to work out that this particular Emperor has no clothes. But to mix my metaphors I will keep on pulling the levers like the Wizard of Oz, until someone pulls back the curtain. It’s been a while since I undertook a big book project and do I kind of miss that. I tip my hat to colleagues of mine who have held down full-time jobs at VMware, and writing books. I don’t know how they find the time or motivation. As for myself I do a project that’s been cooking away since last year (or if I’m honest the year before) it looks ripe for launch. I hope to do the big reveal in the next couple of weeks.

What was your best experience or fondest memory related to blogging?

[Mike] I guess my fondest memory, is when people come up to me at VMUGs and say they laughed out loud – at something I wrote in a book or blog. Humour is rather under-rated virtue in IT, I don’t know how many of us get through the working day without being able to laugh at the end of it….

Any advice for others who are new to blogging?

[Mike] Blog about you – your experiences and what you learn. Most of start blogging as way of documenting what we learn. Its a bit odd how you end up searching your own blog for stuff you worked out 12 months ago, because your memory synapses have made room for some other data. As for ‘making a name for yourself’ – I would recommend finding a topic that is unloved, and becoming the GOTO guy/gal for that. Get a reputation for being a really nice person who helps other people. If you lucky, you’ll hit upon a technology that just explodes in popularity – and will put a rocket under your career. If it happens 99% of that will be pure luck, the other 99% will be sheer goddamn hardwork. Then, rest on your laurels and dine out on your veteran status until retirement. Well, that’s what I plan to do anyway… ;-)
