ServerWatch recently published a list of the Top 10 Virtualization Experts that you need to follow and I’m honored to be included on that list along with some other very distinguished people that deserve to be there. I can’t dispute any of their choices which includes a dream team of virtualization superstars: Jason Boche, Scott Lowe, Chad Sakac, Rick Vanover, Stephen Foskett, Alan Renouf, Duncan Epping, Chris Wolf and Vaughn Stewart. My only comment is that there are plenty of other people that deserve to be there as well and if you want to see a larger list check out my Top 100 list that I published 6 months ago.

David, Simon and I recently got together for a new vChat episode and the topic of choice was my favorite topic these days, VVols. We also give updates on what we’ve been up to recently and we promise to be recording more vChat episodes on a regular basis. Also check out David’s link page that references the topics we talk about.

I did a post a few years ago on VMworld bands that I’m updating after the band for this year was announced. Much to my disappoint they failed to get a big name band in favor of two lesser known obscure bands, Neon Trees and Alabama Shakes. I’ve been attending VMworld since 2008 and the official parties have always been a fun way to unwind for a bit and escape after a busy week of hard core virtualization. VMware has had a variety of different bands to play at the party over the years that are listed below:
- 2007 – Smash Mouth (Treasure Island)
- 2008 – DJ & Tainted Love (cover band) (Las Vegas Speedway)
- 2009 – Foreigner (Moscone)
- 2010 – INXS (Moscone)
- 2011 – Killers (Venetian)
- 2012 – Jon Bon Jovi & the Kings of Suburbia (Moscone)
- 2013 – Train and Imagine Dragons (AT&T Park)
- 2014 – The Black Keys (Yerba Buena Gardens)
- 2015 – Neon Trees and Alabama Shakes (AT&T Park)
I like a wide range of music but the only two bands that I really enjoyed seeing at VMworld were INXS and Foreigner which are in the classic rock era that I grew up with. In 2012 I was excited to find out that Jon Bon Jovi was playing which is another band I grew up with but the actual performance I thought was terrible as he played mostly cover songs from other bands and very few Bon Jovi songs. Train in 2013 is an OK band, I like a few of their songs but they are not a band I have a strong desire to see. The Black Keys is another decent band but again don’t have a strong desire to see them. This year they hit a new low though with two small bands that many people have not heard of and I really have no desire to see.
VMware is a big company and certainly has the deep pockets needed to hire bigger name bands, it certainly would be nice to see decent bigger bands play at the VMworld party (they certainly are saving money on those crappy box lunches they feed us). You might wonder how much does it cost to hire a real big name band (a lot), I did some digging and found out. Now if we price out the VMworld bands over the years we get this:
- 2007 – Smash Mouth – $40K – $60K
- 2008 – DJ & Tainted Love (cover band) – probably not a heck of a lot
- 2009 – Foreigner – $40K – $50K
- 2010 – INXS – ? (prob under $100K)
- 2011 – Killers – $500K
- 2012 – Jon Bon Jovi & the Kings of Suburbia – $850K
- 2013 – Train and Imagine Dragons – Train – $200K-$300K, Imagine Dragons – $400K – $600K
- 2014 – The Black Keys – $975K
- 2015 – Neon Trees and Alabama Shakes – Neon Trees – $40K – $45K, Alabama Shakes – $90K – $125K
From 2011 – 2014 VMware spent a considerable amount of money on the musical entertainment for the VMworld party. This year that has totally dropped down to only $150K total. Now for that budget, it limits what decent well known bands you can get, here’s a couple that I would of liked to see that would fit in that budget:
- 38 Special – $35K – $45K
- Blues Traveler – $40K – $40K
- Cheap Trick – $45K – $70K
- Creed – $100K
- Jefferson Starship $15K – $25K
- Paramore – $125K – $175K
- Puddle of Mud – $35K – $50K
- Slash – $45K – $65K
Here’s the cost of some additional big name bands, that I would love to see play VMworld:
- Nickelback – $350K – $500K
- Pearl Jam – $300K – $500K
- Linkin Park – $400K – $500K
- Bruce Springsteen – $1 million
To contrast this here’s the bands that have played at some other big tech conferences over the past few years, EMC seemed to scale down this year as well with the combined band total being about $300K. Oracle and Cisco had huge budgets as Aerosmith costs $1.3 million to hire:
- 2010 – Counting Crows
- 2011 – The Fray
- 2012 – Maroon 5
- 2013 – Bruno Mars
- 2014 – Imagine Dragons
- 2015 – Fall Out Boy and One Republic
- 2011 – Paul McCartney
- 2012 – Sheryl Crow & Don Henley
- 2013 – Santana
- 2014 – No band
- 2015 – Spazmatics
Oracle Open World:
- 2010 – Black Eyes Peas & Don Henley
- 2011 – Sting
- 2012 – Pearl Jam and Kings of Leon
- 2013 – Maroon 5 & The Black Keys
- 2014 – Aerosmith with Macklemore & Ryan Lewis
- 2015 – TBA
- 2010 – Smash Mouth
- 2011 – Train
- 2012 – Weezer
- 2013 – Journey
- 2014 – Lenny Kravitz and Imagine Dragons
- 2015 – Aerosmith and Royal Machines
EMC, Cisco and Oracle go all out with some great entertainment (HP used to). Every year I hold out hope waiting for the announcement that we’ll get a great band at VMworld but after this year I’m starting to lose faith.

I was going through some VVol documentation and found this comparison between VVol limits and VMFS/NFS limits in vSphere 6.0:
VMFS/NFS Limits # VVol Limits #
VMDK size 64TB Data VVol size 64TB
Virtual Disks per host 2,048 VVols bound to a host 4,096*
LUNs/NAS mounts per host 256 Protocol Endpoints per host 256
Volume size 64TB Storage Container size 2 ^ 64**
Volumes per host 256 Storage Containers per host 256
Adapter Queue depth 32 Adapter Queue depth 32
Configured VASA Providers per host 128
storage arrays per ESXi host
* A host can see more than 4096 VVols, but can have only 4096 VVols bound at any given point in time (binding occurs when a VM is powered on)
** ridiculously large number
Some additional notes:
- While multiple VVol Storage Containers are supported, it’s up to each vendor to decide what they want to support. Today many vendors only support a single Storage Container which encompasses an entire storage array.
- While multiple VVol Protocol Endpoints are supported, it’s up to each vendor to decide what they want to support. Today most vendors only support a single Protocol Endpoint for the entire storage array.
- The minimum size of a VVol is 1MB. Storage arrays must support at least 2TB VVols.
- The maximum size of a data‐VVol is as large as whatever vSphere supports (62TB). The maximum size of a config‐VVol is currently 4GB. ESXi hosts will never try to create a virtual volume larger than what the array advertises as maximum.
- The maximum number of VVols supported by a storage array is up to each vendor to decide what they want to support. The maximum number of VVols required by VMs in a cluster of ESXi hosts is the product of maximum number of virtual disks per VM (60), maximum number of snapshots per virtual disk (32), and maximum number of VMs per vCenter cluster (10,000). This make the theoretical maximum around 19 million total VVols.
- The minimum number VVols a powered-on VM will have is 3 (config, swap, data) (swap goes away when VM is powered off). Each snapshot will add at least one additional VVol per virtual disk (plus an additional if memory state is selected). The maximum number of VVols a powered-on VM could have is around 2,000: 1 – config, 1 – swap, 60 – data, 1,920 – snapshots (60×32), 32 – memory state.

VMUGs are great events for VMware professionals to interact and learn and the MyVMUG team has done an excellent job executing the UserCon events but I wanted to comment on something that I have seen this year at the VMUG events. I’ve been a VMUG Leader in the past and am currently with a partner who sponsors VMUG events so I have perspective on both sides of the fence.
The only way VMUG UserCon’s can happen is through sponsor funding from partners which ranges from $3,500 to have a booth at the event up to $9,000 for a platinum sponsorship that gets you a speaking session and some other perks. Depending on the size of the event which varies by city there can be anywhere from 25-75 partners sponsoring a single UserCon event. As these events are at larger venues such as hotels and convention centers they get pretty expensive to execute for everything such as signage, travel, giveaways, food, drink and more. The sponsor funding is what makes these events possible and covers all those expenses.
The VMUG UserCons have multiple session tracks throughout the day where anywhere from 3 – 8 sessions are going on simultaneously that users can choose from. The sessions at VMUGs are encouraged to be technical and educational and partners have to submit an abstract that must be approved by the local VMUG leaders. A lot of sponsor sessions focus on the sponsor’s products and many sponsors do a good job of making them technical and educational but sometimes they can turn in to sales/marketing pitches. Depending on the attendee they may or may not be interested in hearing that but they have multiple sessions to choose from.
Gold and Platinum sponsors all get a 45-min speaking session at the event. In addition to sponsor sessions, VMware is brought in to spice up the event and make it more educational and interesting so you can hear VMware employees talk about VMware technology subjects. This is good as it makes it more attractive for attendees to come and also entice them to stick around throughout the day. However the problem comes when you start mixing together sponsor and VMware sessions in the same time slots.
If an attendee has a choice of hearing VMware talk about what’s new in VSAN or a deep dive on vCenter or vCloud Air or hear a sponsor talk about storage or backups, 8 times out of 10 they will choose the VMware session. As a result this screws over the sponsor which has paid over $5,000 to have a speaking session and ends up having a mostly empty room as everyone is in a VMware session instead. There is a simple fix to this that was implemented years ago by separating the VMware sessions from the sponsor sessions so they are not mixed together in the same time slots. However the discretion to schedule sessions is up to the local VMUG leaders and despite the MyVMUG staff highly recommending it be done this way the ultimate decision is up to the VMUG leaders.
I can point to two events this year that prove the impact that this has on sponsor session attendance. I was at the KC VMUG a few weeks ago and did a very technical deep dive on VVols that I thought would be well attended. However the KC VMUG leaders chose to mix together VMware sessions with sponsor sessions as shown below and as a result I had maybe 20 people in the room as everyone else was in VMware sessions.
Fast forward to the Seattle VMUG today, the VMUG leaders there chose to keep the VMware and sponsor sessions in separate tracks as shown below and as a result the same session that we did on KC was completely full with standing room only.
This clearly illustrates the impact of mixing VMware and sponsor session in the same time slots and the negative impact it has on sponsor sessions that pay a lot of money for the opportunity to speak to attendees. I have getting screwed at the upcoming Indy VMUG to look forward to as the VMUG leaders there have also chosen to mix sessions together. As the sponsors are the only ones that make the event even possible, it’s a shame that they get screwed over like this as it kills the value of sponsoring the event for us.
So if you’re a VMUG leader I encourage you to carefully consider this and schedule accordingly. I personally will be asking ahead of time now and may choose not to sponsor an event if the sessions are going to be mixed together. I’m sure other sponsors have recognized this as well and may re-consider sponsoring these events. As a VMUG leader your budget for the event is dictated by the number of sponsors you get so its advantageous to you to make the experience for your sponsors as good as possible so they will come back next year.
If you’re a partner and want to express your concerns send the MyVMUG staff an email as I have already done at sponsors at vmug.com.
VMUGs are excellent events that bring together the VMware community and I’d like to see them continue to have value for both the attendees and the sponsors. Hopefully VMUG leaders will help improve session scheduling to give us sponsors a fighting chance and have the opportunity to have bigger audiences at our sessions.

So I’ve been pretty disconnected from everything over the last 4-5 weeks or so as I’ve been relocating from AZ to CO just in time to beat the 110+ degree heat. The whole move process took much more effort than expected so I haven’t had much time (or energy) for much else than moving and work. Despite having done the reverse move 2 years ago this one was harder mainly because getting my house that I had rented out when we moved to AZ back in shape took a lot of time, money and effort.
Starting with 2 foot long grass that tppk hours to cut, to internet and cable snafus and mix-ups that left me without services for days. I went with Comcast as its the only real option in my area with DSL being a crappy 20Mbps and bought a Surfboard modem, I elected to do a self install so I could get it up and running quickly. Well that went south real quick as I could not connect once I hooked up the modem and it turns out they had disconnected it from the top of the utility pole out back so there was no way for me to get it going. Days later they finally came out and fixed that, I initially went with DirectTV as I dislike the Comcast X2 setup, they showed up without the equipment I ordered on the phone with them and wanted to me to buy all sorts of expensive boxes so I kicked them out and went with Dish who came out a few days later, so far I’m happy with them.
Some tall grass:
From there I had to deal with water damage in the finished basement in 2 different areas from a broken outside spigot that froze when someone left a hose on it in the winter to clogged gutters and re-directing water away from the house. I had to rip out drywall and carpet padding, get the pipe fixed and re-do the drywall and carpet which was a big job. Add in very overgrown trees, bushes and hedges, appliances that need replacing, other plumbing issues and all sorts of other misc work and I’ve been going non-stop on that. Still trying to get organized, finally got my man cave up and running a week ago, well mostly that is but I’m finally at a state where most of the hard stuff is done.
Lots of drywall to fix:
More near the ceiling:
I was out at the KC VMUG last week, I’ll be going to the Indy VMUG in July and Chicago VMUG in Sept. I’ll also be at VMworld presenting in 3 sessions as well. I had to take a break from shipping Top vBlog coins during the move process, I think I’ve sent out about half of them. The rest should be going out in the next week so if you don’t have yours yet you should soon.
So I’m back in the saddle again, expect to see lots more content here soon!

VMware just opened the public voting on session submissions for VMworld 2015. The way sessions are usually approved is via an independent content committee that reads through and scores each session submission, the ones with the highest scores make it in. I did it one year and it was a very tedious job and it was something I would not want to repeat again. VMware also allows certain larger sponsors to score a select group of sessions, I was offered that role at HP this year and turned it down.
The public voting is a route for sessions that might not make it through the normal content committee scoring process to be selected as a VMworld session, VMware refers to these as Customer Choice sessions. The odds are small that a session will make it given the very large number of session submissions but their is a glimmer of hope. I copied the voting table into a spreadsheet and it came out to around 5,280 rows with each session taking up 3 or 4 (2 speakers) rows so there is at least 1,500 submissions to sort through. As a result your session submission can very easily get lost as it appears they are all listed in random order. There are search and filtering functions that can be used as well.
According to the FAQ, VMware claims they reserve space on the VMworld agenda for up to 5% of Customer Choice sessions. As there were about 400 sessions last year that means less than 20 will be chosen based on public voting, so again chances are slim that your submission will get through this way unless get the word out for people to vote for you.
You need a VMworld account to vote, its quick and easy to create one and voting is open from now until May 26 at 11:59pm PDT. You
can vote on as many sessions as you’d like but you can only cast one vote per session. So with that said, here’s my plea for you to consider voting for my session submission on VMware Virtual Volumes. If you like all the content I’ve written here on them I think you will really enjoy the session as well. Feel free to also vote for my other submissions including the technical panel on VVols that VMware is hosting.
To do this simply click the Display Filter Options when you login to the voting site and put in the keyword “Siebert” and when the results display click the thumbs up to vote so it turns green. You can do further filtering and searching to find all the other sessions you want to vote on. I thank you for your vote and good luck to all!

I’ve been collecting VVols information and links to add to my VVols link page and ran across some interesting items that I thought I would share. Let’s start with events:
- Taneja is doing a deep dive webinar with Dell into their implementation on VVols on May 14th at 9:00am PST as a follow-up to the other VVols webinars that they have done with a group of partners as a panel and with VMware. Look for me to be participating in one as well soon representing HP.
- Tintri is doing a VVol webinar this week entitled “Top 5 VVOLs Myths and Misconceptions”, I don’t know that there are many myths about VVols floating around but I am sure there are some misconceptions so you might check it out. As Tintri touts their storage as being able to work at the VM level without VVols I’m sure the myths might be tied to that in an effort to promote their implementation. This one is also on May 14th at 9:00am PST so you’ll have to pick which one you want to watch live.
- NexGen is doing a series of events in various cities from May 19th – June 24th with storage veteran Howard Marks entitled “Putting VVols to work – Storage Best Practices for vSphere 6 and Beyond”. If Howard is doing these they have to be good so be sure and attend if it comes to a city near you, right now they have listed Dallas, San Diego, New York, Atlanta, Seattle, Santa Clara and Denver.
Now for some other VVol info:
- VMware has just published a new KB article detailing interoperability between VAAI offloads and VVols storage. It’s a bit short as it summarizes it, you can find a much more detailed version of it in this blog post from Rawlinson at VMware.
- VMware has published another KB article that details how UNMAP works with VVols, however it might not be what you think. With VVols there is no longer the need to perform UNMAP operations as was necessary with VMFS using the vmkfstools and esxcli commands as the storage array sees VMs as objects and knows when they are deleted or moved so it can automatically reclaim that space. This KB article covers UNMAP from within the guest OS which is now possible as UNMAP commands initiated by a guest OS that supports UNMAP are passed back to the storage array to be reclaimed. I asked Cormac Hogan at VMware about this about a year ago and he confirmed this would work but know we have confirmation of it. In addition this apparently works with VMFS as well now in vSphere 6 as Cormac details in this blog post.
- Veeam announced that they now fully support vSphere 6 and VVols with their new Update 2, so naturally I was curious and tried to find out more detail around their VVol support. They have listed as a new feature “Quick Migration to VVol datastores”, right now the only migration path from VMFS to VVols is using Storage vMotion so it sounds like they are doing something similar to copy a VM from VMFS to VVols. The Veeam Quick Migration feature is not a live migration like a Storage vMotion so there is a brief disruption as they pause the VM after it is copied and then resume it. I’m guessing they are using the vSphere 6 VDDK which now supports VVols to be able to do this as I don’t think they can have a backup appliance connect directly to a storage array using a Protocol Endpoint similar to the Direct to SAN method in VADP. I’ve reached out to Rick Vanover to clarify their support for VVols and how it impact’s their Direct to SAN backup method.
- Still only 7 vendors listed in the VMware HCG for VVols support, I wonder when EMC, Dell, Pure and others will finally join the VVol support club.
That’s all for now, read lots more about VVols in my ever growing VVols link page.
Update from Rick Vanover at Veeam:
1) Does this mean you support the Direct to SAN method to backup a VM that is in a VVol storage container? If so are you establishing a protocol endpoint from your backup appliance/VM to the storage device?
>> Hot Add and NBD only. This is due to the VDDK capabilities.
2) What’s your quick migration method from VMFS to VVols? As it stands Storage vMotion is the only way to move a VM to VVols, are you simply doing a backup/restore or something else? Is this cold or hot?
>> VVols or VMFS makes no difference as VDDK abstracts that for us, so our prior logic still applies. In short, we create a new VM and stuff its virtual disks with data from the source VM (same as our replication jobs do). Migration “temperature” will depend on migration scenario and engine used: hot for VMotion, “warm” for Smart Switch, cold in other cases.

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 Jason Boche, a good friend of mine from way back to the days when we were VMTN moderators together. Jason is one of the only bloggers that I know that has a full fledged data center running in his basement to power his home infrastructure services and serve as his home lab for blogging at boche.net. Jason mentions VMworld 2008 were I convinced him to start blogging, here’s a pic of some of us doing the Community Roundtable podcast way back in the early days live from VMworld and also a pic of Jason after he tried to explain what vMotion is to Danica Patrick.
Jason has a fondness for cigars so if you ever run in to him at a VMware event be sure and pack a few stogies to smoke with him. So without further ado enjoy a Q&A session with Jason Boche:
What year did you start your blog?
[Jason] I started my blog in the year 2008.
What inspired you to start a blog?
[Jason] I gained a lot of knowledge and experience working with VMware products in a large corporate environment as well as in my home lab. I had also spent a lot of time sharing the knowledge that I had gained early on with others in the VMware community forums. Blogging and other forms of social media was gaining popularity as output channels for content and after a discussion with my Eric Siebert at Las Vegas Motor Speedway in 2008, that seemed to be the next logical step.
Describe your early blogging experiences and how you have evolved over the years?
[Jason] When I got my blog started up in my home lab, my brain was overflowing with blog articles I wanted to get out. Early on I think I was producing many blog articles on a daily basis. That eventually slowed down to a more reasonable and digestible rate but managing an enterprise datacenter with VMware and other infrastructure products still gave me plenty to write about in the coming years. Four years ago I transitioned out of a customer role and moved to the VMware partner side of the world where I work for a storage vendor. My blogging output has dropped considerably during this period. Part of this is due to the lack of operational day in day out hands on VMware products that I used to have, and part of it is due to a personal shift with more time and focus spent on my growing family. Sharing and giving back to the community what I can was and still is very rewarding but it comes with a cost which is a time component. Over the last few years my priorities have shifted from community to family. It’s evident in my blogging and my participation in other social media avenues. I haven’t given up completely, it’s just a re-balance.
What has kept you blogging over the years and not quitting at it?
[Jason] Datacenter architecture and technology is in a perpetual state of evolution and transformation. I still have plenty to learn and in turn share with others. Blogging is one of many facets of community. Community is important to me and for as long as I can remember, I’ve been wired to support others and give back which I have done in many ways throughout my lifetime. The name Jason translated from Greek literally means “healer”.
What was your best experience or fondest memory related to blogging?
[Jason] Positive feedback from others that I’ve helped them or saved their weekend in some way. I’ve been there and I know the feeling of mental and physical exhaustion and eventually overwhelming relief when a problem is solved.
Any advice for others who are new to blogging?
[Jason] Your blog therefore you are in control with your own rules. Don’t get caught up by others telling you what you should and should not do with your blog in terms of content or frequency. When a blog becomes a job, the fun and passion will be sucked right out of it. Monetization may or may not come. Don’t force it. It shouldn’t be a the primary goal if you already have a day job. Use it to cover expenses, not get rich. A genuine, friendly, and modest personality will draw readership. Be approachable but maintain boundaries for life/family balance. Blog output requires just as much or more input – continue learning and the sharing part will come easier.

On a VMFS volume a VM is comprised of many files that all have different purposes, the configuration file for a VM (.vmx) is a small text file (<100KB) that contains various information about the virtual hardware configuration of the VM. With the Virtual Volumes (VVols) architecture the configuration information for a VM is stored in a different manner. Before we go there though lets take a look at how a VM is stored on VVols versus VMFS, the below picture illustrates the files that make up a VM on VMFS.
With VVols a VM is still comprised of different object types just like VMFS but many of them have been consolidated so there are fewer objects. A VM on VVols is made up of a minimum of two files, a Config VVol and a Data VVol, once a VM is powered on a Swap VVol is created to support memory over-commitment on a host which is then deleted when a VM is powered off just like with VMFS. There are additional VVols created for each snapshot that is taken of a VM as well as any memory states included with snapshots. So where did all those other files go that are part of a VM on VMFS such as log files, descriptor files, lock files, etc? They all get packing into the Config VVol.
While a config file on VMFS is quite small, with VVols it’s much larger as it’s allocated with 4GB of space by default. It’s allocated thin though so the actual size will be much smaller but it has the potential to grow as the data within it grows. Below is a screen shot from a 3PAR array that shows the Config VVol, you can see that is is provisioned thin (tpvv) and the actual physical space it consumes is around 2GB (1996MB). Also note the Swap file is fully allocated, this is necessary as the file is used for virtual RAM and it will be equal in size to the memory that is assigned to a VM (minus any memory reservations).
So what’s all in the Config VVol, the virtual hardware configuration of a VM of course but it also contains descriptor files for virtual disk and snapshots. With VMFS you always had 2 files that were created for each virtual disk, a small descriptor file and the larger data file, with VVols the Data VVol is the virtual disk and the descriptor is in the Config VVol. You also have all those individual .log files that exist for each VM on VMFS all combined into the Config VVol as well as any lock files that get created.
So there you have it, I don’t know if it’s possible to reclaim space inside a Config VVol like you can within the Data VVol using UNMAP. The max size of a Config VVol is 4GB, as most of the files are small, they probably truncate and remove log files as needed to ensure that it doesn’t exceed that size. Also all of the data inside a Config VVol is mostly text based data, I’m not sure how it’s structured inside the VVol container I’ll have to see if I can get a look inside one to find out.

In today’s virtual world where disk-based media rules and everything is interconnected via the internet there is a very high probability that you’ll need replication for BC/DR to get your valuable VMs protected off-site to another location. Fortunately Zerto makes that simple by offering a virtual-aware, software-only, tier-one, enterprise-class replication solution purpose-built for virtual environments. Unlike traditional storage array replication which requires like brand and model storage arrays at each site to be able to replicate with each other, hypervisor based replication is storage agnostic meaning it operates above the physical storage layer at the virtual layer so it supports any type of underlying storage on each side. Another advantage of using HBR is that it allows you to replicate at the more granular VM level instead of the larger scale LUN level.
It works by using only two components, the Zerto Virtual Manager (ZVM) which is a Windows-based service that acts as the management console and can be accessed via a plug-in to vCenter, the ZVM manages all vSphere replication and keeps track of applications and information in motion in real time. The other component is the Virtual Replication Appliance (VRA) which is deployed as a virtual appliance (VM) on each host and continuously replicates data from user-selected VMs, compressing and sending that data to the remote site. The following diagram shows how Zerto Virtual Replication is deployed across sites as a DR solution:
Zerto does one thing, replication and they do that well, I’ve always admired them and thought that had a great solution. They were founded in 2010 and their product debuted shortly after that and won the Gold in the BC/DR category for the Best of VMworld awards in 2011. It also won Best of Show which means is was chosen as the best product across all the many awards categories. I noticed a quote from Jo Maitland while on Zerto’s website that essentially stated the decision was a no-brainer. As a former Best of VMworld judge myself I know that feeling well as I was involved in a similar situation in a prior year with the product I had picked as the winner in the Security category, HyTrust which also easily won Best of Show.
So if you are in the market for a great BC/DR solution, I highly encourage you to go checkout their replication solution for VMware vSphere environments. One thing to get you started is this great overview and demo video. They have a lot of great and smart folks that work at Zerto that you should follow on Twitter as well, and be sure and read this great post entitled “I am not a booth babe, Ask me a question” by Fara Hain, Zerto’s Director of Marketing.

Another VVols webinar coming up from Taneja Group who is doing a whole series of webinars on VVols, the first which was on April 2nd and I participated in was a panel discussion with several storage vendors (NetApp, HP, NexGen & Dell) giving their views and opinions on VVols. The next one on April 30th features two speakers from VMware: Juan Novella (Product Marketing Manager) and Ken Werneburg (Senior Technical Marketing Architect). It should be a good and informative session and it is the prelude to some additional Taneja deep dive webinars on VVols from individual vendors. I’ve signed on to represent HP at one which will be held in May. So click the link below and register and find out what VMware has to say about VVols.
Join us for the first in a series of fast-paced and informative 60-minute webinars, as we discuss with VMware one of the hottest topics in the datacenter: VMware vSphere Virtual Volumes (VVol). VVol is the industry’s first solution to enable native virtual machine-awareness across a broad range of SAN/NAS arrays. VVol is packaged as a feature in nearly all VMware vSphere Editions and is being embraced by storage partners at an unprecedented rate. IT professionals, especially those involved in datacenter operations, are showing great interest in implementing VVol in their own environments.
This moderated session features Juan Novella and Ken Werneburg, VVol experts from VMware, who will discuss VVol technology, the rapidly expanding ecosystem, and the impact this game-changing capability will have in the datacenter. Attendees will be encouraged to submit their questions during the session.

I’ve started shipping the Top vBlog 2015 coins that were custom made this year courtesy of Infinio to the Top 50 bloggers. I’m sending them out in small batches due to all the work packing them, printing labels, filling out customs forms, etc. When you receive yours you might find a something little extra in the package courtesy of Nutanix who is providing a coin holder and lanyard so you can proudly wear your coin around your neck. Just imagine how cool you would look wearing it around your house, at the grocery store, in your office or even at VMworld.
So when you receive yours in the mail, give a shout out to Nutanix and Infinio and post a picture of yourself wearing it on Twitter with the hash tag #TopvBlog2015. Bonus points for whoever has the most creative photo.
