VMware vSphere 4.0 capabilities

My company had the great opportunity to participate to the private beta of VMware vSphere (formely VMware Virtual Center/ESX 4).

Since December last year we have ran several series of tests and we found this new version just superb.

Unfortunately due to a NDA we could not share any information but since last week many information has been released at VMworld Europe 2009.


Rick Sherer attended several sessions and shares with us a list of the new capabilities:

Virtual Machine Maximums
Virtual CPUs per Virtual Machine – 8
Size of RAM per Virtual Machine – 256GB
NICs per Virtual Machine – 10

ESX Host Maximums
Hosts per Cluster – 64
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.
