Want to learn more about the new Replication functionality for VVols in vSphere 6.5? If you are a VMware partner you can sign-up for a vmLIVE webinar next week on 11/15 at 7:00am PST. I’ll be co-presenting with Ben Meadowcroft who is the VMware product manager for VVols. We’ll be covering what’s new with VVol’s in vSphere 6.5, much of which is around replication and how HPE 3PAR StoreServ has implemented support for it. So if you are a VMware partner head on over to VMware’s Partner Central website and sign-up. If you are not a partner you won’t be able to sign-up but you can still read my overview on VVols replication and also check out my VMworld 2016 session which covers it as well.

One thing I noticed that was missing from the vSphere 6.5 release which is expected at some point is support for an in-band VVol bind process that a host must perform when a VM is powered on. The current VVol implementation is an out-of-band process which involves the VASA Provider which acts as the control path between vCenter, ESXi hosts and a storage array. In this post I’m going to go into detail about the bind process and why it would be beneficial to be an in-band process.
So first the basics, the concept of binding a VM to it’s disk files is unique to VVols. With VMFS/NFS we didn’t need this process as you have a file system in place that can handle file look-ups and locking. With VVols we don’t have a file system written to the storage array, VMs are written natively to the array as VVol objects which are essentially sub LUNS (block) or files (NFS). There still is a mini VMFS file system with VVols but it is contained within the Config VVol of a VM. So because we don’t have a file system we need a way to connect a VM to it’s VVols when it is powered on.
When a VM is powered on using VVols the bind operation is performed which connects a host to all of the VVols associated with that VM. When a VM is powered off those VVols are then unbound from the host as there is no need for them to be connected and a host can only bind to a limited number of VVols (4,096). To perform the bind though the host needs to know where the VVols of a VM reside and for that it needs to lookup the sub LUN ID’s for each VVol so they can be bound to.
Sub LUN’s are also a new concept with VVols, VMware had to request modifications to the SCSI T-10 standards to support the concept of sub LUNs. A sub LUN is basically a secondary level of LUNs, a host cannot directly see sub LUNs and they will not be visible during any SCSI scans that a host performs. To connect to a sub LUN a host must first connect to an administrative LUN which is visible to the host but it’s a special LUN with no provisioned storage and a bit set identifying it as part of a conglomerate. This administrative LUN is known as the Protocol Endpoint.
So to look up the sub LUN IDs for a VVol, a host has to ask someone for that information. The storage array knows the sub LUN IDs but a host can’t ask it directly, it must instead make the request to the VASA Provider which looks up the sub LUN information on the storage array and passes it on to the host so it can proceed with the bind. Because this process involves an intermediary and is not direct it is considered out-of-band. So essentially the host is asking for directions to get to it’s destination and once the VASA Provider provides it with an address (sub LUN ID) it can directly connect to those VVols via it’s direct in-band data path.
Now the VASA Provider component can be implemented either within a storage array or as an external component such as a VM appliance, it’s up to each vendor to choose how they want to implement it. No matter which way it is implemented the connection to the VASA Provider is via standard network protocols (TCP/IP) and not via a storage protocol (Fiber Channel/NFS/iSCSI). The connection to the VASA Provider is typically over your network via a management port on the storage array, if it’s external you have to connect to whatever VM/server is running the VASA Provider and then on to the storage array. Because the VASA Provider is connected over your standard network it is an out of band operation, to be an in-band operation a host would have to be able to perform this lookup via the data path using whatever storage protocol it is using to connect to the storage array. Below is a diagram which illustrates the components and paths that are used with VVols:
So now that you understand the difference between in-band and out-of-band binding, why does it matter which way you do it, either way you are getting the job done. Well performing the bind operation in-band has several advantages related to performance and availability compared to an out-of-band bind operation. An in-band operation will be performed quicker and more efficiently as a result of having a smaller number of network hops and by using faster in-band network connections. In addition a storage controller will typically higher processing power available to perform the operation faster. There is also no overhead imposed by the entire SOAP based VASA communication that is used when doing an out-of-bind operation.
Doing an in-band bind operation also provides overall better availability and reliability as you are not relying on a 3rd party to perform the operation which if it failed would prevent binding from occurring. This is especially true of external VASA Providers, if they crash, go down or something happens to them for whatever reason you cannot power on VMs until it is back up. In addition it also simplifies the bind process and makes it less likely that a mis-configuration could impact it.
So it sounds like in-band binding is definitely the way to go, why isn’t VVols using it yet? It appears VMware needs more time to implement this, I have seen mentions of in-band binding in both the VASA 2.0 & VASA 3.0 developer documentation. It looks like much of the framework to support in-band bind is already part of the VASA 3.0 spec so I expect to see the capability become available eventually in an upcoming release. Here’s what the developer guide says about this:
The vSphere 6.0 and 6.5 releases did not implement in-band bind. Bind is one of a few VVol management operations that are required for VM power-on. Failure to bind results in a “Data Unavailable” event that reflects poorly on storage system reliability. As a member of the T10 SCSI standard committee, VMware has been working to add in-band BIND and UNBIND commands to the SCSI standard. The intent was to define an in-band alternative to the corresponding VASA calls and enable use of the data path between host and storage array to power-on a VM when the network path between host and VASA provider is unavailable. When the T10 standard is finalized the specifications will be added to the VASA specification.
So for now we’ll just have to wait, once VMware completes what it needs to for in-band bind to be enabled in the VASA spec it will then be up on the storage vendors to make changes on their side to make the switch over to in-band bindings. Regardless of whether a bind operation is in-band or out-of-band it doesn’t impact the many benefits that VVols provides right now. The benefits of in-band binding will be under the covers and provide an extra lit bit of efficiency and reliability. So why wait, get started using VVols today and if you want to read more on VVols be sure and check out my huge VVols link collection and also read about what’s new with VVols in vSphere 6.5.
Oct 20 2016
VMware recently announced vSphere 6.5 and it includes the next big version of Virtual Volumes (VVols) which is based on the updated VASA 3.0 specification. The initial release of VVols was part of vSphere 6.0 which went GA in March 2015 and was based on VASA 2.0. VVols has been out now for over 18 months and with vSphere 6.5 expect to see maturity, improvements and of course a big capability that was missing in the initial release, support for array based replication.
Before I go into what’s new with VVols 2.0, lets first re-visit what I’m currently seeing around customer adoption of VVols. I’ve spoken to dozens of customers and surveyed hundreds of people in my sessions at Discover, VMUGs and VMworld. When I ask who is using VVols today I see very few hands go up. That’s really about what I expected at this point, most companies avoid 1.0 products, the same held true with VSAN, there are additional reasons as well such as lack of replication support, not on vSphere 6.x yet and not understanding what VVols is and the benefits it brings.
I expect that to start to change though, I have also spoke to plenty of customers, some very large that are in the planning phase for migrating to VVols. The release of vSphere 6.5 should help drive adoption as VVols unofficially becomes a 2.0 product and is more complete with support for replication. As far as the understanding aspect goes I think VMware hasn’t overall done all that great a job of helping customers with that. My feeling on that is mainly based on my own observations and interactions with VMware. I do know for a fact that the VMware VVols product management team has done a good job promoting VVols but they are a relatively small part of a big company.
If you watched the VMworld EMEA keynotes were vSphere 6.5 was introduced, you didn’t here a single mention of VVols. Other features like VSAN, NSX, encryption, vRealize, cloud, VM scale, vCenter, new Web UI, etc. all were mentioned. There was a brief callout in the vSphere 6.5 press release but not many people read those. The same was true with the early access blogger briefings that VMware does so the bloggers get the early scoop so they can write about it at launch, VVols was strangely absent. With the initial release of VVols they put a lot more effort into VVols marketing and awareness but this time around it has been relatively quiet. I’d really like VMware to step it up and see people like Pat Gelsinger, Ray O’Farrell and Yanbing Li talking about VVols as well. I know I’m doing my best to evangelize VVols and educate the community and I know other partners are doing so as well but it would be good to see VMware try and do more at all levels of their organization.
So let’s now cover what’s new in VVols 2.0 and really the focus here is all on Replication as there is not much else new. Under the covers I expect there are a lot of improvements but VASA is really a development specification or an enabler for storage vendors to develop their own implementations of array based capabilities to integrate with Storage Policy Based Management (SPBM). As a result every vendor implementation of VVols will be slightly different as it’s up to each vendor to dictate how they can scale, how they implement the VASA provider, what capabilities they will present to SPBM, etc.
With vSphere 6.5 storage array vendors can now implement replication of VVol-based VM’s through the creation of Replication Components and attaching them to vSphere Storage Policies. Previously, a storage policy was a single set of rules built from the list of capabilities offered by the array. With vSphere 6.5 those rules have been broken up into different capability types, known as Components that allows you to define a capability once and re-use it in multiple storage policies. There are different Component class types which include Replication, Performance and Encryption. The below figure show how the Component section in the VM Storage Policy management interface in the vSphere client.
Once you create a Component, you tie it to a vCenter Server, name it and then select the Provider type, in the below figure you can see the multiple types of Providers available in vSphere 6.5 including Replication.
Next you define the properties for the Replication Component, this can include the target Storage Container and disk groups, how frequent replication will occur and desired RPO levels as shown below.
Once you have your component defined you can add it to a VM Storage Policy as shown below, note a Storage Policy can have multiple Components added to it.
Now that your Components are created and assigned to Storage Policies when you go to create a VM on VVol storage when you get to the Storage selection screen and choose an existing Storage Policy to assign to that VM you will also see the option to select a Replication Group for that VM based on what is defined in the policy. as shown below. You can choose from an existing Replication Group or a new one will be automatically created for you. Only existing groups that match the replication constraints defined in the policy will be displayed. A replication group is the minimum level of failover and will contain one or more VVol objects (multiple VMs). Any Replication Group that is automatically created will also be automatically removed once their are no more VMs assigned to it.
Some other things to note about replication, all of a VM’s VVol objects will be replicated to the target to ensure VM integrity, this includes and snapshots attached to the VM. Replication may be array based but it is solely designed to be implemented and managed by vSphere via SPBM and other vSphere interfaces. You must configure Storage Containers on both the source and target arrays before creating replication profiles. While it is possible to replicate only certain disks of a VM to a target site, a VM must have all of it’s VVols that it is replicating in teh same Replication Group.
So while it is great that we now have array based replication with VVols, how do you actually make use of it in a real world DR scenario? In this release there is no automation component like SRM to orchestrate replication, failover, testing, failback, etc. Eventually vRealize Orchestrator will be able to do much of this but for now all operations must be scripted using the VVol APIs that exist. There are 3 main operations that you can do in this release, a test failover, an actual failover (planned or unplanned) and a reverse failover (recovery). All of these operations are strictly performed within the vSphere environment, your storage admin is not involved in any of this.
Under normal operations VVols at the secondary site are hidden from vSphere and can not be bound to. When you perform a test failover it is not a true failover operation, just a simulated one. What happens is the VVols at both the primary and secondary sites remain in their current state and copies of each replica VVol are made at the secondary site so they may be presented to the vSphere environment and are now capable of being bound to at the secondary site for testing. These copies are in a consistent state and vSphere will automatically fix-up the copies so they can be utilized for testing purposes. Once testing is complete all of the VVols at the secondary site will cleaned up and removed.
If you perform an actual failover it is initiated from the secondary site, a final sync operation is performed (planned failover) and replication is halted between the sites. If the failover is forced or unplanned the secondary site is not allowed to contact the primary site. After the failover call is made to the VASA Provider at the secondary site, the VVols at that site become visible and are able to be bound to hosts. After a failover, the only operation allowed is is to recover the group (failback). As the primary site can no longer be the replication source, vSphere will issue a reverse operation. A reverse operation essentially just sets up replication back to the primary site where you can failback at some point when needed. As part of a planned failover you initiate both the failover and reverse replication at the same time.
As far as the orchestration of all this I’m still trying to come up to speed on that so as I learn more I’ll provide more detail on that. For a planned failover you will have to manually script (i.e. PowerCLI) out the workflows as you don’t have a tool like SRM to build them for you. At some point vRealize Orchestrator and Automation will be capable of doing all this but until then you will have to build this on your own. I suspect VMware will have all the tools, docs, sample scripts, etc to help you with this. I’m actually just kicking off a tech paper that will cover how to do this for 3PAR, however most of the workflows/scripts should be generic as they are calling the standard tasks outlined in the VASA 3.0 specification.
You can also read more about the capabilities in VVols 2.0 on the VMware Virtual Blocks blog.
Oct 19 2016
A long time ago in a vSphere version far, far away VMware introduced support for automatic space reclamation which allowed vSphere to send UNMAP commands to a storage array so space from deleted or moved VMs could be un-allocated (reclaimed) on the storage array. This was a welcome feature as block storage arrays have no visibility inside a VMFS volume so when any data is deleted by vSphere the array is unaware of it and it remains allocated on the array. UNMAP was supposed to fix that so when data was deleted vSphere would send a string of UNMAP commands to the array telling it exactly which disk blocks it could have back. Doing this allowed thin provisioned storage arrays to maintain a much smaller capacity footprint.
Shortly after this feature was introduced in vSphere 5.0 which was released back in 2012 problems started surfacing. As the UNMAP operation was real-time (synchronous) vSphere would have to wait back for a response from the array that the operation was complete. In many scenario’s this wasn’t a problem, but some arrays apparently had problems completing the operation in a timely manner which would cause timeouts and disk errors in vSphere. As a result VMware quickly issued a KB article recommending to disable UNMAP support and in vSphere 5.0 Update 1 they completely disabled it.
What VMware did next was introduce a manual reclamation method by modifying the vmkfstools CLI command and adding a parameter to it that allowed UNMAP to run on an array as a manual operation. While this worked it took quite a while to execute and was very resource intensive on the array. The reason for that is all the manual operation was doing was creating a balloon file using un-used space on a VMFS volume and then sending UNMAP commands to the array to reclaim it all. The end result was that instead of reclaiming just the blocks from deleted VMs it tried to reclaim all the remaining free space on the VMFS volume which was terribly inefficient. You can read all about how this all worked in this post I did back then.
So since that time VMware has never figured out a way to make it work again until now. In vSphere 6.5 they have again made in an automatic operation but not in the same way as before. What they did was kind of a compromise, instead of trying to do it all as a synchronous operation they are now scheduling it and sending UNMAP commands in bursts to the storage array in an asynchronous manner. So it is truly an automatic process now but it operates in the background and how fast it works is based on priority levels that can be set on individual VMFS datastores.
Now this only works in vSphere 6.5 and only on VMFS6 datastores, VMFS5 datastores must still use the manual method using the esxcli command to reclaim space with the balloon file method. When you create a VMFS6 datastore the default priority will be set to Low which sends UNMAP commands at a less frequent rate to the storage array. In the vSphere Web Client you will only see the option to change this to either None or Low with None disabling UNMAP completely. However using the esxcli command (esxcli storage vmfs reclaim config) you can also change this setting to Medium or High which increases the frequency in which UNMAP commands are sent by 2x (Medium) and 3x (High) over the Low setting.
Now why did VMware not allow you to choose Medium or High from the Web Client? There is a good reason for that, they hid those options for your own good. UNMAP is still a resource intensive operation, when you do an UNMAP operation you are literally telling the array to un-allocate millions or billions of disk blocks. When you get more aggressive with UNMAP commands it will start putting a heavier load on the storage array which can seriously impact your VM workloads as the array tries to handle everything at once. Having this set to Low is a good compromise as you get your disk space back automatically but with minimal impact to your VM workloads. If you do happen to set it to Medium or High via esxcli it will still show those settings in the Web Client, you just can’t select them there.
So welcome back UNMAP, we missed you and are glad to have you back. Of course if you are using VVols you don’t have to worry about UNMAP at all as the array has VM-level visibility and knows when VMs are deleted and can reclaim space on it’s own without vSphere telling it to.

Oct 18 2016
VMware has just announced a new release of VSAN as part of vSphere 6.5 and this post will provide you with an overview of what is new in this release. Before we jump into that lets like at a brief history of VSAN so you can see how it has evolved over it’s fairly short life cycle.
With this 6.5 release VSAN turns 2 1/2 years old and it’s remarkable how far it has come in that time frame. Note while VMware has announced VSAN 6.5 it is not yet available, if VMware operates in their traditional manner I suspect you will see it GA sometime in 30 days as part of vSphere 6.5. Unlike previous versions there isn’t a huge list of things that are new with this release of VSAN but that doesn’t mean that there are not some big things in it. Let’s now dive into what’s new in VSAN version 6.5.
Customer adoption of VSAN continues to increaseWith this release VMware is claiming that is has over 5,000 VSAN customers and they they are the #1 hyper-converged vendor. That 5,000 number sounds low to backup that #1 claim but VMware is basing this on total revenue and not customer counts. VMware had stated that they have an over $100 million revenue run rate and over 20,000 CPU licenses sold with VSAN back when they had over 3,000 customers which would put the average VSAN deal size around $30,000. The VSAN growth rate over the past two years according to VMware has been as follows:
From these numbers it appears that VMware has added a lot of VSAN customers in the last 6 months which can be attributed to their aggressive sales/marketing and rapid product development life-cycle.
VSAN is going mainstream with the #1 use case being business critical appsBack when VSAN was first announced VMware had positioned VSAN as more for VDI, Tier 2/3, ROBO and dev/test use cases. As VSAN has evolved and acquired increased scalability and resiliency as well as enterprise features VMware has been claiming since vSphere 6.0 that it is ready for the enterprise and business critical/Tier-1 apps. Apparently VMware has done some customer research (249 respondents) and is claiming that business critical apps are the #1 VSAN use case by quite a large margin. I don’t really doubt that number as VSAN is a significant financial investment for customers and when you are making that big of an investment in storage you are going to maximize your usage of it. Add in all-flash support and enterprise features and I can definitely see that many customers running business critical apps on VSAN as I suspect VSAN serves as the primary vSphere storage platform for those customers.
VMware is trying to make All-Flash affordable for everyoneBased on licensing models in prior releases of VSAN you had to pay a All-Flash tax if you wanted to get the maximum performance that VSAN can offer by utilizing all SSD storage. With VSAN 6.2 the Standard license was priced at $2495/CPU and did not include the ability to use VSAN in an all-flash configuration. To get all-flash support you had to purchase VSAN Advanced license which was priced at $3,995/CPU which also included de-dupe, compression and erasure coding. VSAN Enterprise was priced at $5495/CPU and added on support for QoS and stretched clustering.
With VSAN 6.5 that all-flash tax is gone but with a caveat, you can deploy VSAN in an all-flash configuration now with the Standard license but you do not get the space efficiency features with it, for that you still have to move up to an Advanced license. In addition VMware is offering a new VSAN Advanced ROBO license that brings all-flash and space efficiency features for ROBO at a more affordable price point. This new ROBO licensing will be sold in 25-VM packs, if you exceed 25 VMs you have to move up to the regular VSAN license tiers. All in all with the affordability of all-flash media these days it looks like VMware is responding to try and not alienate customers that want to use all-flash but can’t afford higher licensing tiers.
New 2-node Direct Connect deployment modeRemember back in the day when we used to use special cables to connect two PC’s directly together and then use Laplink to transfer data back and forth between them. Because you had a direct connection between the devices it was cheaper, easier, faster and more secure to transfer data. The same holds true with storage devices, a direct connection eliminates the need for connecting 2-nodes together via a network switch, this was fairly common with SAS storage devices.
In vSphere 6.5 VMware has come out with a new 2-node direct connect deployment model for those use cases were it might be desirable to connect only 2 VSAN nodes together such as ROBO or SMB. This can help drive down costs as it eliminates teh need for 10Gbps switches, it also reduces the deployment complexity and helps customers with compliance concerns as VSAN traffic will never touch the network. Basically this solution involves just connecting a NIC port from one VSAN node directly to another VSAN node using a special crossover network cable. In prior versions of VSAN this wasn’t possible as you had both VSAN traffic and witness traffic were occurring on the same VMkernel port so if you used a direct connection there was no way to communicate with the witness.
To make this possible in VSAN 6.5 you now have the ability to separate out witness traffic onto a separate VMkernel port which essentially de-couples it from the VSAN traffic flow. To use this solution it is recommended to use 2 VMkernel connections in an active/standbay configuration. You then have to designate which vmKernel interface will have the witness traffic by using an esxcli command. You can continue to use vMotion with this type of configuration.
VSAN can now provide storage to more than just vSphere hosts with iSCSI supportThis is a big one, in prior releases VSAN presents out storage to ESXi hosts and other VSAN nodes via a proprietary communication protocol, what this means nothing but an ESXi host could use VSAN for shared storage. In VSAN 6.5 the proprietary protocol is still used as the main transport between hosts but support for industry standard protocols has been added in the form of iSCSI support. What this means is that potentially any device in the data center be it physical or virtual could utilize VSAN as primary storage.
Why is this big? It opens the door for VMware for VSAN to be used for just about every use case in the data center and eliminates the barrier that may have previously existed that required customers to deploy an additional primary storage array to fulfill their non-vSphere shared storage needs. In other words VSAN is now positioned to take over your entire data center. However VMware is currently not targeting this solution to support non-VSAN ESXi clusters, but those shouldn’t exist in a perfect VSAN world.
iSCSI support is being done natively from within the vmKernel and not using any type of virtual appliance. There are some scale limitations with only 128 targets supported and 1024 LUNs but the solution is compatible with Storage Policy Based Management so you can use extend SPBM to more than just VMs. To use this you must first enable the Virtual SAN iSCSI target service and select a VMkernel port which automatically sets this amongst all of the VSAN cluster nodes. You can then select a default SPBM policy and optionally configure iSCSI authentication (CHAP). You then configure LUN information such as the LUN number and size (up to 62TB) and optionally multiple initiators.
Enhanced PowerCLI supportVSAN PowerCLI has been enhanced for those that want to automate VSAN operations to include things like Health Check remediation, iSCSI configuration, Capacity and Resync monitoring and more.
Support for Cloud Native Apps running on the Photon PlatformFinally VSAN support has been extended to support additional VMware Cloud Native Applications to now include the Photon Platform. This positions VSAN to be able to handle any VMware-centric container deployment model.

VMware just announced vSphere 6.5 almost a year and half after the release of vSphere 6.0 and this post will give you a quick summary of all the new features and enhancements in this release. There is actually quite a lot packed into this release and rather than try to cover it all in detail here I will be doing separate posts that go into much more detail on vSphere 6.5, VM Encryption, VSAN, VVols and much more. As much of the new stuff is more minor in nature I first wanted to highlight a few big things in this release.
And now for the full list which is based on the VMware published What’s New doc from the Beta 3 release combined with my own additions and embellishments.
The only remaining function that has dependencies is Windows Session Authentication, so any user that does not use this functionality does not need to install CIP.
