vSphere release cycle bounces back to the old VI3 days

Back in 2013 I did a post comparing number of days between major vSphere releases that highlighted VMware’s fast pace of delivering new vSphere versions. That fast pace has now slowed down considerably with vSphere 6.0 as VMware wasn’t able to keep up with the zippy one year cycle they had fallen into. Now with the release of vSphere 6.0 we’re back to around the same numbers of days that it was at years ago with VI3. One of the reasons for the delay was most likely due to the engineering of the new Virtual Volumes (VVOLs) storage architecture which took considerable time and effort to complete. Whether that will continue or not as yet to be seen, the next release of vSphere may not be as big as this one was. VMware now has many of their new architectural changes in place so they may speed up again based on the development efforts required for the next vSphere release.

Only 4 vendors support VVOLs on Day 1 of vSphere 6 GA

VMware has added a new category to their Hardware Compatibility Guide specifically to show vendor support for Virtual Volumes (VVOLs) called vSphere APIs for Virtual Volumes (VVols). On Day 1 of the vSphere 6 launch just 4 partners showed up as supporting VVOLs on their storage arrays, those partners & supported models are shown below:

VVOL-HCL

Below is a detailed listing if you click on one:

VVOLs-HCL2

A summary of the the full list of what storage array models are currently supported by those partners is shown in the below table:

PartnerModelsArray TypeFW/OS Ver.Features
HP3PAR StoreServ 7000 & 10000 StorageFiber Channel3.2.1
IBMXIVFiber Channel11.5.1Multi-VC,VPHA (active-passive)
NEC iStorage M110, M310, M510, M710Fiber Channel & iSCSI010A
SANBlaze TechnologyVirtuaLUNFiber Channel & iSCSI7.3Multi-VC,VPHA (active-active)

I few things to note about the above:

  • Of the 3 original VVOLs design partners (HP-Fiber Channel, Dell-iSCSI, NetApp-NFS) only HP delivered day 1 support for VVOLs. This doesn’t mean the other arrays don’t support VVOLs yet, their array firmware may very well support it but they haven’t completed the certification process yet. Expect to see more show up as vendors complete their certification process.
  • The Features field in the VVOLs listing is a bit mis-leading as it doesn’t indicate which storage array features each vendors supports with VVOLs such as snapshots, QoS, thin provisioning, etc. No vendor specific features are part of the certification process, the tests may use specific features but it doesn’t know what those features are. Instead this column lists features related to the implementation such as if multiple vCenter Servers (Multi-VC) are supported with the VASA Provider and if the VASA Provider has High Availability (VPHA) features built-in. Note vendors can choose to implement their VASA Provider embedded within the array or externally as a VM or physical server. Of the ones listed I know that 3PAR implements their VASA Provider in the array and IBM’s is external as part of their Storage Integration Server.
  • Certification is protocol specific, right now all 4 vendors support Fiber Channel and only NEC & SANBlaze supports iSCSI. Expect to see NetApp show up as supporting NFS and Dell EqualLogic as supporting iSCSI.
  • In the listing their is Profile section which lists Virtual Metro Storage Cluster, all arrays listed say No for this as vMSC is currently not supported with VVOLs.
  • The VASA provider version is based on VMware’s current VASA Provider specification. Version 2.0 was the new VASA Provider spec in vSphere 6 that was specifically developed to support VVOLs replacing the version 1.0 in vSphere 5.x. I’d have to check the latest specification document but I’m assuming 2.1 was an incremental upgrade to this. I have no idea why SANBlaze lists their as 7.3.

UPDATE:

On the VASA Provider version I checked with our engineering team and that is the version specific to each vendors VASA Provider. So this is not related to VMware’s  VASA 2.0 specification and is really up to the vendor on how they want to version their specific VASA provider.

Maximum Virtual CPU support cut in half in vSphere 6.0

I was reviewing the Configuration Maximums document for vSphere 6.0 which was released today and comparing it to vSphere 5.5 to see what has changed and noticed that the maximum Virtual CPU support (vCPU) was reduced by half from 4,096 in vSphere 5.5 to 2,048 in vSphere 6.0. Not sure if this is a typo or if this is actually the case, it seems odd though as the support for the number of physical CPUs in a host has increased from 320 in vSphere 5.5 to 480 in vSphere 6.0. Also note the number of VM’s per host has doubled from 512 in vSphere 5.5 to 1,024 in vSphere 6.0 so the reduction in the max vCPUs seems strange.

vSphere 5.5 Configuration Maximums:

config-max-55-arrows

vSphere 6.0 Configuration Maximums:

config-max-60-arrow

UPDATE: VMware must of read my post and fixed their error in the vSphere 6.0 documentation, the supported vCPUs in vSphere 6.0 remains the same as vSphere 5.5 at 4,096.

vSphere 6.0 is now available!

You can download it here.

Also check out the documentation here, the first doc that I always go to is the Configuration Maximums to see how things have grown.

And be sure to read through my Summary of What’s New in vSphere 6.0 post and check out my huge vSphere 6.0 Link-O-Rama.
