VMware vSphere 4.0 – Configuration Maximums

A lot of information about the upcoming 4.0 release of VMware’s Enterprise Virtualization product, vSphere, has been released at VMworld Europe 2009.  I’d like to share some of the exciting new capabilities in this upcoming release.

Virtual Machine Maximums
Virtual CPUs per Virtual Machine – 8
Size of RAM per Virtual Machine – 255GB
NICs per Virtual Machine – 10

ESX Host Maximums
Hosts per Cluster – 32
NFS Datastores per Host – 64
Virtual Machines per Host – 256
Physical CPUs per Host – 64
Logical Processors per Host – 64
Total Cores per Cluster – 4096
Virtual CPUs per Core – 20
Size of RAM per Host – 512GB
Total RAM per Cluster – 32TB
Maximum Network Throughput – 40GB/s (Maximum of 4-10GbE Network Cards per ESX Host)

Not including the above we’re also going to get Fault Tolerance, VM Safe, vNetwork Distributed Switch, vShield Zones, vCenter CapacityIQ, vCenter Data Recovery, vCenter ConfigControl, vCenter Orchestrator, vCenter Chargeback and vCenter AppSpeed.

I completely agree with the statement Paul Maritz made during General Session of VMworld Europe 2009 that, “vSphere will let firms virtualize all of their workloads”.  Bravo VMware…Bravo.

    They’ve also doubled the number of storage IOPS per ESX host to 200k (from 100k in ESX 3.5).

    Has ANYthing been announced about pricing — even rumors??

    I haven’t really heard anything in regards to packaging or pricing. I would assume Enterprise would remain the same price and perhaps include FT and maybe even ChargeBack. Only time will tell, if I hear anything I will definitely post.

    Rick, have you heard any updates as to pricing or licensing information for vSphere? We’re purchasing the hardware and licenses for our virtual infrastructure which must be done prior to the end of April and I’m hoping that the SnS subscription for VI3 enterprise includes (as I was told it should) an upgrade to vSphere.

    JR, If you have a valid SnS Subscription then you’ll have no problem receiving the upgrade to vSphere.

    They haven’t officially released prices and packages yet, but I can only speculate that if you purchase VI3:Enterprise that you’ll get all of the features VI3:Ent has in vSphere.

    I think we’ll know a lot more (officially) on the 21st :)

    Gentleman,
    Do you have any idea about the VCP exam upgradation…from VI3 to VI4(vSphere).?
    Thanks.

    The VCP exam release will be shortly after it becomes GA. I’d speculate that this should be available around June.

    FYI, Pricing for vSphere will be released to partners later this month (April) via Partner webinars. Then we’ll find out all the details, upgrade paths, etc..

    The maximum amount of memory that you can give a VM is not 256GB but 255GB.

    Thanks for catching this Erik, this was written with information from the Beta & I never got around to updating it.

    How someone can get Total Cores per Cluster – 4096

    if 32 is max per cluster and 64 is max per host – 32*64 = 2048??? What I have missed?

    Thanks Eugene for catching that. A lot of these numbers were based on alpha and beta releases of vSphere. The final number is 32 nodes per cluster * 64 cores per node = 2048. The nodes per cluster was once 64 (pre GA), I’ve since changed the number to 32 but did not catch total cores.

    If looking at Nehalem-EX, it will be 4096 threads per cluster :)
