How to experience VMworld EMEA 2016 without attending it

be_tomorrowVMworld EMEA usually ends up being a re-run of VMworld US but this year promises to actually be more exciting than the US edition was. The main reason for this is that VMware announced very little at VMworld US and overall the announcements were a bit lackluster. This year the timing of the new versions of VMware’s core products were a bit too far out from VMworld US so VMware will doing a lot of big product announcements at VMworld EMEA instead. As a result you are going to be wanting to pay attention to VMworld EMEA and if you can’t attend I’ll tell you how to do it.

The bloggers

There are hundreds of bloggers that write about VMware technology and there is no shortage of bloggers that attend VMworld and report on what they see, hear and experience at the show. You can expect bloggers to write about anything from thoughts and opinions on products and companies to what parties they attended to live blogging about sessions they attend. Even bloggers who are not attending the show will be posting about the announcements at the show as VMware has held pre-show blogger early access briefings. So blogs are a great way to tap into all the information relevant to the show and the announcements.

Once of the best ways to keep up with what the bloggers are posting is checking out my recently re-vamped and re-launched Planet vSphere-land which serves as a post aggregator for the top 100 vBloggers as well as VMware official blogs. The VMworld EMEA website also has a special list of VMworld bloggers along with feeds to keep you informed of all the latest blogger posts. You can also check out the official VMworld blog as well.

Twitter

If you’re not on Twitter by now, why not? You may not be that social or the chatty type but its a great way to listen in on the thousands of people on social media all talking about VMworld in real time. So if you don’t have an account, sign-up now before VMworld and then use the many VMworld focused twitter resources to listen in and participate. The @VMworld account is the official account for VMworld so make sure and follow it, you also might follow the most popular bloggers as well to see what they are saying about VMworld. You can see the top bloggers here along with their twitter handles and also check out my list of the Top 100 VMware/virtualization people to follow.

You’ll also want to keep an eye on hashtags that flag tweets that related to a specific topic. The official hashtag for VMworld is #vmworld (not #VMworld2016 or #VMworldEMEA) there are also hashtags specific to each session (#sessionID) and fun ones such as #vmworld3word and #vmworldselfie. VMware also has a Social Stream of Twitter feeds available that is like a giant tweet billboard that you can watch to see the latest Twitter action at VMworld.

Live streams

VMware doesn’t live stream breakout sessions but they do live stream the 2 main general sessions which are where all the new product announcements are made. The opening general session (Tuesday) is historically more focused on VMware’s high level vision and strategies as heard from Pat Gelsinger and I’m sure Michael Dell will make an appearance. The 2nd general session (Wednesday) is more focused on the details and specific products and technologies and typically features more techie speakers such as Sanjay Poonen, Ray O’Farrell, Kit Colbert and Yanbing Li. The general sessions are at 9:00am London time so they are pretty late for us in the states (1:00am PST) but they always post the replay for you to watch after the session is over. To sign-up to view the general sessions live head on over to VMware’s general session live streaming page and pre-register where you can put in your email address and be sent a calender invite for them.

YouTube

I’m pretty sure VMware will have a camera crew roaming around VMworld EMEA recording content for VMworld TV which will be narrated in part by the famous Mr. Sloof. In the past they featured a nice roll-up of the days happenings that summarized everything using the recordings that were made throughout the day. Keep an eye out on the VMware TV YouTube channel for posted recordings.

View recorded sessions

Almost all breakout sessions at VMworld US were recorded as it’s impossible for attendees to see more than a small fraction of the amount of total sessions (700+). The recordings allow attendees to watch each session after the event is over to check out all the great sessions that they could not attend while at the event. The audio for all sessions is recorded and presented along with the slides for each session, in some cases for more popular sessions they have video recorded them as well at past VMworlds.

This year VMware decided to release all of the recordings to the general public so you can go there and watch them now. Most of the sessions at VMworld EMEA are re-runs of the US sessions and are not recorded again except for panel type sessions that are usually different at each event. Because of the unique announcements at VMworld EMEA this year there will be session that were not at VMworld US, VMware has posted a list of them here. I suspect they will be recorded and available after the show as well.

VMware on Amazon Web Services – if you can’t beat ’em, join ’em

vnw-amazon1Oh the irony in yesterday’s announcement by VMware that they are now partnering up with Amazon Web Services to offer vSphere as a Service running in the AWS cloud. This is quite a change of heart from their stance years ago when they saw AWS as a rival and enemy. Remember back in 2013 when they first announced their vCloud Hybrid Service running in VMware managed data centers in conjunction with Savvis. They have steadily built out their now called vCloud Air infrastructure to many locations across the globe to provide vSphere as a Service to customers to better compete with their main rival AWS in the cloud market.

As part of that rivalry AWS launched a management portal intended to attract VMware customers to AWS by allowing them to easily import VMs into AWS through vCenter. VMware quickly responded warning customers of all the management and integration complexities that could be jeopardized by doing that. Pat Gelsinger also lashed out at AWS saying “We want to own corporate workload, We all lose if they end up in these commodity public clouds. We want to extend our franchise from the private cloud into the public cloud and uniquely enable our customers with the benefits of both. Own the corporate workload now and forever.”

Fast forward to today and it appears VMware has had a change of heart and is now partnering with Amazon Web Services to offer vSphere as a Service on AWS. What is not clear though is what VMware intends to do with their existing vCloud Air infrastructure that it offers both within its own 10 data centers and across over 4,000 cloud partners across the world. It would seem like they are simply trying to expand their presence to one of the biggest cloud service providers in the world, Amazon enjoys 31% percent cloud market share and is growing like crazy (63% YoY). It makes total sense that VMware would want to tap into that, AWS has a great reputation and lots of cloud muscle and VMware opens itself to a much big market. With that much added capacity VMware may eventually decide to get out of the data center business and rely on it’s partners which makes sense as they are primarily a software company.

So lets now take a look at the details of this announcement. One thing to note is that this new service has only been announced and there is a bit of a long wait for it to be available, VMware is stating that it will be available in mid 2017. If you are interested in trying it out VMware does have a beta form that you can fill out to apply and also get updates about the service. There will be two licensing options for this service, on-demand (hourly) and subscription-based (1 year, 3 year), customers will also be able to leverage their existing investments in VMware licenses through VMware customer loyalty programs.

Another thing to note is VMware is not referring to this as vCloud Air, it is specifically being referred to as VMware Cloud on AWS. vCloud Air is specific to all of their other public cloud offerings and services. VMware laid the groundwork as a key enabler for this type of solution at VMworld in August with their Cross-Cloud Architecture announcement. While VMware Cloud will be running on AWS infrastructure, VMware will still be managing it. The overall solution as pictured below allows customers to run ESXi on dedicated infrastructure (not nested) in AWS data centers while having management (vCenter) running within their own data centers (for on prem vSphere) as well with vCenter running in AWS and at the same time having access to value added AWS Services.

vnw-amazon2VMware is offering their full software stack on AWS which includes VSAN for storage and NSX for networking, replication capabilities and more. All of this offering is 100% managed by VMware, that includes buying it through VMware, the configuration and upgrades to the environments and support is also through VMware.

vnw-amazon3Because this is a 100% native vSphere environment it will be managed by the customer using all of the native tools, scripts and familiar UIs that they use to manage their own vSphere environment as shown below, there is no AWS management UI layered on top of this. Because it is running in AWS it makes re-sizing simple as additional AWS infrastructure will automatically be allocated and added into existing clusters. Since it can be managed alongside existing customer on-premise vSphere infrastructure you could potentially also migrate VMs via vMotion back and forth as needed.

vnw-amazon5The key components in this solution are shown below, the first is what VMware refers to as the Service Console (not to be confused with the ESX Service Console), the Service Console is a VMware provided service that runs as a web application on VMware’s website (not AWS). The Service Console provides you with all of the administrative for the service itself which includes sign-up, provisioning, scaling up/down, billing and more. You are not doing any direct vSphere management through the Service Console. The next component is the Cloud Data Center itself which is simply the combination of AWS supplied hardware and the vSphere software stack. The AWS Global Infrastructure is the next component which is essentially their networking, data center services and everything else that makes AWS tick, again the billing is all-inclusive and comes from VMware itself not AWS. The whole solution is designed to look like it is coming directly from VMware with AWS operating transparently in the background.

vnw-amazon6The below figure shows what the Service Console UI looks like, it’s a simple HTML5 web-based interface that VMware developed for the initial setup and ongoing management of the VMware Cloud services on AWS. From here you can create deploy new VMware Cloud environments, see the status of existing ones, open the vCenter web UI for each instance and other actions for provisioning, scaling and billing. It is all designed to support VMware’s REST API’s so you could automate many of these actions through scripting. The authentication mechanism is the existing My VMware one that VMware uses today to manage support, licenses and billing which allows you to have one account for both your on prem vSphere and AWS vSphere cloud environments. Again, it’s designed to be a one stop shop at VMware for everything.

vnw-amazon7Next the below figure illustrates the combination of the AWS hardware and infrastructure combined with the VMware software stack. It’s pretty much the same stuff that you would deploy in your own data center. vCenter Server runs as an appliance, it can be deployed stand alone or in linked mode for single pane of glass management with your own on prem vCenter environment. VSAN, NSX Manager and Platform Services Controller are installed and available and of course as many ESXi hosts are configured on dedicated hardware as needed to support your requirements based on the capacity you specify. All of this is pre-configured and pre-provisioned as part of the service, you do not have to run through and set any of this up your self which is what this type of solution is all about, insert credit card and out pops a running vSphere environment. The other nice thing about this is VMware is responsible for keeping your environment up to date with patches and new vSphere versions, you don’t have to do a thing.

vnw-amazon8Finally the below figure illustrates how it can be deployed in any of the many worldwide AWS regions that exist today and in the future. Customers can connect to their VMware clouds using IPsec public network connections or direct connections to AWS.

vnw-amazon10VMware’s goal with this is to eliminate boundaries between public clouds and private data centers and allow customers to more easily build hybrid cloud environments. Of course for VMware this is a win/win situation as no matter where you run vSphere you’re still a VMware customer running their software stack. As VMware only sells software they really don’t care where the hardware comes from. By design this solution provides greater flexibility and more choices for customers to run their vSphere environments in. You can find out more about this new offering at the below links:

Who were the best vendors at VMworld 2016?

Every year since 2007 TechTarget does their Best of VMworld awards which highlights the best vendors at the show within specific categories as chosen by a panel of independent judges (non-vendor). I’m always curious to see who receives the top honors at these events as it often highlights vendors I may not of head of before. As a former judge myself for several years I know the process that goes into making the selections and always felt it helped me learn more about the many innovative vendors in the VMware ecosystem.

Vendors have to nominate themselves to be eligible for consideration by filling out a form on Tech Target’s website before the show. Judges are picked from an independent pool of customers and VARs and then assigned to a specific category. Judges then review the vendors in their category before the event and often pre-judge to shrink down the number that they have to visit at the show. There is a list of rules and criteria for consideration when trying to determine which vendors are the best. During the show judges visit a select group of vendors to ask questions and find out more about a vendors product that was nominated. Judges then meet together and discuss their picks as the best vendors for each category and then also pick one vendor from the category winners to be chosen as overall Best in Show.

Before I list the winners of each category I wanted to give my perspective on these awards. If you look historically at past winners each year you typically won’t see big name vendors like IBM, EMC and Symantec, etc. winning these awards. The reason for that is these awards tend to be about uncovering those innovative smaller companies that are doing things uniquely and outside the box. I’m not saying big companies can’t innovate but startups often bring fresh ideas and perspectives to doing things in a way that nobody has ever tried before. They are not afraid about taking risks and going against the status quo and solving a problem in a whole new way.

I judged the security category each year that I did it and some of my picks for the winner of that category were companies like HyTrust and Reflex Systems. I knew right away when I talked to these vendors and saw their products that they were something special. Sometimes it’s not so easy though as there are so many vendors with great products in the VMware ecosystem and a lot of small startups all with their own ideas trying to capitalize on the opportunity that virtualization has brought about for new products. At the end of the day though the judges make their choices no matter how easy or difficult that decision is and based on their opinions the best vendors at VMworld are chosen.

So here are the winners this year, one hiccup this year, Cohesity DataProtect 3.0 was originally chosen as the winner for Data Protection but then was later found ineligible as the product release that they were being judged on was not released yet which is a requirement for being eligible. As a result the two finalists were chosen as co-winners in that category.

Category winners:

  • Data Protection – Co-Winner: StorageCraft ShadowProtect SPX  Co-Winner: Rubrik Firefly 3.0
  • Workload Management & MigrationEmbotics vCommander 5.7.2  (Finalists: Velostrata 2.0 and ExtraHop Networks)
  • SecurityShavlik Protect  (Finalists: Thycotic Secret Server and GuardiCore Centra Security Platform)
  • Virtualization & Cloud InfrastructureNVIDIA GRID with Horizon 7  (Finalists: Nutanix Xpress and Actifio Sky)
  • Desktop & Application DeliveryWorkspot VDI 2.0 Solution  (Finalists: Unidesk 4 and Citrix Secure Browser)
  • Networking & VirtualizationVeloCloud Cloud-Delivered SD-WAN  (Finalists: Paessler PRTG Network Monitor and  VMware vRealize Network Insight)
  • Agility & AutomationTufin Orchestration Suite  (Finalists: Quali CloudShell Cloud Sandbox Software)
  • Judge’s Choice Disruptive TechnologyLakeside Software Ask SysTrack
  • Judge’s Choice Startup SpotlightStacksWare

And chosen as Best in Show which is the top honor is Tufin Orchestration Suite

Congrats to all the winners this year! If you are interested in seeing past years winners you can view them here:

Knock, knock – Who’s there – Vembu – Vembu who?

Vembu VMBackup for vSphere, that’s who.

I’ll be honest, when a data protection company called Vembu reached out to me last month I have to admit I had not heard of them before. Despite working neck deep in the virtualization world for the last 10 years and have attended every VMworld the last 9 years Vembu is a company I had never heard mentioned. A big part of the reason for that is Vembu is based out of India and initially focused on the managed service provider (MSP) market by providing their StoreGrid software for MSPs to white-label and re-brand to offer as a service to customers. Even ESG has declared Vembu as “The Biggest Little Data Protection Company You Probably Haven’t Heard Of (Yet)”.

Vembu has actually been around for over 12 years and I’m going to tell you a little bit about them. Vembu is a privately held data protection company based in India who recently opened an office in Texas and is now trying to expand their presence to the customer segment. To that end in late 2014, they shifted focus from the MSP market to developing their BDR Suite which is a collection of products meant for on-premise, offsite, cloud backup and disaster recovery across diverse IT environments including physical, virtual, applications and endpoints.

The Vembu BDR Suite caters to the backup needs of the modern data center running VMware/Hyper-V (Vembu VMBackup) as well as physical Windows IT environments (Vembu ImageBackup). They continue to provide all the features of Vembu StoreGrid under the Vembu NetworkBackup product name which is also part of Vembu BDR Suite.  They have a couple of products for VMware environments which includes VMBackup for VMware, OffsiteDR for VMware and BDR360 for VMware. VMBackup for VMware has pretty much everything you would expect a backup application to have and more such as:

  • Agentless VMware Image Backup
  • VM Replication for High Availability
  • VMware Hot-Add and SAN transport mode for LAN free data transfer
  • CBT enabled incremental data transfer using VMware VADP
  • Supports VMware vSphere v6 which includes VMware Virtual Volumes and Virtual SAN
  • Quick VM Recovery
  • Application-Aware Image Backups
  • VembuHIVE File System, a File System of File Systems for efficient backup storage
  • Flexible & Configurable Retention Policies
  • Vembu Universal Explorer for Microsoft Exchange, SQL, Active Directory and SharePoint

They also provide value added features such as automated backup verification, quick VM recovery from backup, instant file level recovery with Universal Explorer, building Virtual Labs from Storage Repositories and Cross Hypervisor Migration (V2V). Sounds like a whole lot of great stuff for a backup application to have, well wait until you see their pricing which they post right on their website.

Most everything is licensed per host CPU socket, VMBackup for VMware is only $360 per CPU socket/annum. If you want to use their OffsiteDR for VMware to your own data center it’s only $90 per CPU socket/annum or CloudDR for VMware to the Vembu Cloud is only $0.20 per GB/month. In addition to data protection they also offer BDR360 for VMware which provides centralized monitoring & management for only $60 per CPU socket/annum.

So if you’re in the market for an affordable data protection solution I’d highly recommend you give Vembu a serious look. To help you out I’ve included a few links below to get you started:

Top 10 reasons to start using VVols right now

VMware’s new storage architecture, Virtual Volumes (VVols), has been out for a year and a half now as part of the vSphere 6.0 release and adoption continues to be very light for a variety of reasons. This kind of adoption can be typical of any 1.0 release as users wait for it to mature a bit and better understand the differences of it compared to what they are used to using. VVols brings a lot of great benefits that many are unaware of so in this post I though I would highlight those to try and make a compelling use case to start using VVols right now.

top10list-crop10 -You don’t have to go all in

It’s not all or nothing with VVols, you can easily run it right alongside VMFS or NFS on the same storage array. Because VVols requires no up-front space allocation for it’s Storage Container, you will only be consuming space on your existing array for any VMs that are put on VVol storage. Since VVols is a dynamic storage architecture, whatever free space you have remaining on the array is available to your VVols Storage Container which is purely a logical entity unlike a VMFS volume which requires up-front space allocation.

You can easily move running VMs from VMFS to VVols using Storage vMotion and back again if needed or create new VMs on VVols. This allows you to go at your own pace and as you move VMs over you can remove VMFS datastores as they are emptied out which provides more available space to your Storage Container. Note that Storage vMotion is the only method to move existing VM’s to VVols and you cannot upgrade VMFS datastores to VVol Storage Containers.

9 – Gain early experience with VVols

VMware never keeps 2 of anything around that do the same thing, they always eventually retire the old way of doing it as it is double the development work for them. At some point VVols will be the only storage architecture for external storage and VMFS will be retired. How long did you wait to switch from ESX to ESXi or to switch from the vSphere C# client to the web client? Did you wait until the last minute and then scramble to learn it and struggle with it the first few months. Why wait, the sooner you start using it the sooner you will understand it and you can plan on your migration over time instead of waiting until you are forced to do it right away. By gaining early experience you will be ahead of the pack and can focus on gaining deeper knowledge of it over time instead of being a newbie who is just learning the basics. There are no shortage of resources available today to help you on your journey to VVols.

8 – Get your disk space back and stop wasting it

With VVols both space allocation and space reclamation is completely automatic and real-time. No storage is pre-allocated to the Storage Container or Protocol Endpoint, when VM’s are created on VVols storage they are provisioned thin by default. When VMs are deleted or moved space is automatically reclaimed as the array can see VMs as objects and knows which disk blocks they reside on. No more manually running time and resource intensive cli tools,  vmkfstools/esxcli to blindly try and reclaim space on the array from deleted or moved VMs. VVols is designed to allow the array to maintain a very thin footprint without pre-allocating space and carving up your array into silos like you do with VMFS and at the same time being able to reclaim space in real time.

7 – It’s available in all vSphere editions

VVols isn’t a vSphere feature that is licensed only in certain editions such as Enterprise Plus, it’s part of the vSphere core architecture and available in all vSphere editions. If you have vSphere 6.0 or higher you already have VVols capabilities and are ready to start using it. VVols is mostly under the covers in vSphere so it won’t be completely obvious that the capability is there. It is part of the same Storage Policy Based Management (SPBM) system in vSphere that VSAN uses and also presents itself as a new datastore type when you are configuring storage in vSphere.

6 – Let the array do the heavy lifting

Storage operations are very resource intensive and a heavy burden on the host. While server’s are commonly being deployed as SAN’s these days, a server really wasn’t built specifically to handle storage I/O like a storage array is. VMware recognized this early on which is why they created vSphere APIs for storage such as VAAI to offload resource intensive storage operations from the host to the storage array. VVols takes this approach to the next level, it shifts the management of storage tasks to vSphere and utilizing policy based automation storage operations are shifted to the storage array.

So things like thin provisioning and snapshots which can be done either on the vSphere side or the storage array side with VMFS are only done on the storage array side with VVols. How you do these things remains the same in vSphere but when you take a snapshot in the vSphere client you are now taking an array based snapshot. The VASA specification which defines VVols is basically just a framework and allows the array vendors to implement certain storage functionality, however they want to handle things within the array is up to each vendor. The storage array is a purpose built I/O engine designed specifically for storage I/O, it can do things faster and more efficiently, why not let it do what it does best and take the burden off the host.

5 – Start using SPBM right now

VSAN users have been enjoying Storage Policy Based Management for quite a while now and with VVols anyone with an external storage array can now use it as well. While Storage Policies have been around for even longer when first introduced in VASA 1.0, they were very basic and not all that useful. The introduction of VASA 2.0 in vSphere 6.0 was a big overhaul for SPBM and made it much more rich and powerful. The benefit of using SPBM is that makes it easier for vSphere and storage admins by automating storage provisioning and mapping storage array capabilities including features and hardware attributes directly to individual VMs. SPBM ensures compliance of defined policies so you can create SLA’s and align storage performance, capacity, availability and security features to meet application requirements.

4 – Snapshots don’t suck anymore

vSphere native VM snapshots have always been useful but they also have a dark side. One of the big disadvantages of vSphere snapshots is the commit process (deleting a snapshot) which can be very time and resource consuming, the more so the longer a snapshot is active. The reason for this is that when you create a vSphere snapshot, the base disk becomes read only and any new writes are deflected to delta vmdk files that are created for each VM snapshot. The longer a snapshot is active and the more writes that are made the larger the delta files grow, if you take multiple snapshots you create more delta files. When you delete a snapshot all those delta files have to be merged back into the base disk which can take a very long time and is resource intensive. As backup agents routinely take snapshots before doing a backup of a VM, snapshots are a pretty common occurrence.

With VVols the whole VM snapshot process changes dramatically, a snapshot taken in vSphere is not performed by vSphere but instead created and managed on the storage array. The process is similar in the fact that separate delta files are still created but the files are VVol snapshots that are array-based and more importantly what happens while they are active is reversed. When a snapshot of a VM on VVol-based storage is initiated in vSphere a delta VVol is created for each virtual disk that a VM has but the original disk remains Read-Write and instead the delta VVols contain any disk blocks that were changed while the snapshot is running. The big change occurs when we delete a snapshot, with VVols because the original disk is Read-Write, we can simply discard the delta VVols and there is no data to commit back into the original disk. This process can take milliseconds compared to minutes or hours that is needed to commit a snapshot on VMFS datastores.

The advantage of VVol array based snapshots are many, they run more efficiently on the storage array and you are not using up any host resources. In addition you are not waiting hours for them to commit, your backups will completed quicker and there is no chance of lost data from long snapshot chains trying to be written back into the base disk.

3 – Easier for IT generalists

Because storage array management shifts to vSphere through SPBM, IT generalists don’t really have to be storage admins as well. Once the initial array setup is complete and the necessary VVols components created, all the common provisioning tasks that you would normally do on the array to support vSphere are done through automation. No more creating LUNs, expanding LUNs, configuring thin provisioning, taking array based snapshots, etc., it’s all done automatically. When you create a VM, storage is automatically provisioned on the storage array and there is no more worrying about creating more LUNs, determining LUN sizes and increasing LUN sizes when needed.

With VVols you are only managing VMs and storage in vSphere, not in 2 places. As a result if you don’t have a dedicated storage admin to manage your storage array, an IT generalist or vSphere admin can do it pretty easily. Everything with SPBM is designed to be dynamic and autonomic and it really unifies and simplifies management in a good and efficient manner to reduce the overall burden of storage management in vSphere. Instead of having the added complexity of using vendor specific storage management tools, with VVols management becomes more simplified through the native vSphere interfaces.

2 – It unifies the storage protocols

VMFS and NFS storage are implemented pretty differently in vSphere and what VVols does is dictate a standardized storage architecture and framework across any storage protocol. There were several big differences with file and block implementations in vSphere, with block you presented storage to ESXi hosts as LUNs and with file as a mount point. You still do this to connect your array’s Protocol Endpoint to a host but the standard storage container that is presented to a host to store VMs is just that, a Storage Container, not a LUN or mount point anymore.

When it came to file systems with block an ESXI host would manage the file system (VMFS) and with file it was managed by the NAS array. With VVols there is no file system anymore, VVols are written natively to the array without a file system regardless of it’s a file or block array. And the biggest change is that VMs are written as files (VVols) to block storage in the same manner that file storage has been doing it all along. This creates a  unified and standardized storage architecture for vSphere and eliminates the many differences that existed before between file and block. VVols creates one architecture to bring them all and in the darkness bind them (LOTR reference).

1 – The VM is now a unit of storage

This is what it’s all about, the LUN is dead, because it’s all about the VM, ’bout the VM, no LUN. With VVols the VM is now a first class citizen and the storage array has VM-level visibility. Applications and VMs can be directly and more granularly aligned with storage resources. Where VMFS was very LUN-centric and static creating silos within an array, aligning data services to LUNs and utilizing pre-allocated and over provisioned resources. VVols is VM-centric and dynamic where nothing is pre-allocated, no silos are created and array data services are aligned at the more granular VM-level. This new operational model transforms storage in vSphere to simplify management, deliver better SLAs and provide much improved efficiency. VVols enables application specific requirements to drive provisioning decisions while leveraging the rich set of capabilities provided by storage arrays.
