I’m trying out my frist QuickPress. Let’s see how this turns out.
Right off the bat, I’m missing the autocomplete feature for Tags. As it turns out, typing more than three lines in the small content box isn’t much fun.
On with the VMware content… This all comes from the VMware vSphere Configuration Maximums document. I’ve bolded some of what I’d call core stats which capacity planners or architects would need to be aware of on a regular basis:
15,000 VMs registered per Linked-mode vCenter Server
10,000 powered on VMs per Linked-mode vCenter Server
4,500 VMs registered per 64-bit vCenter Server
4,000 VMs concurrently scanned by VUM (64-bit)
3,000 powered on VMs per 64-bit vCenter Server
3,000 VMs registered per 32-bit vCenter Server
3,000 VMs connected per Orchestrator
2,000 powered on VMs per 32-bit vCenter Server
1,280 powered on VMs per DRS cluster
320 VMs per host (standalone)
256 VMs per VMFS volume
256 VMs per host in a DRS cluster
200 VMs concurrently scanned by VUM (32-bit)
160 VMs per host in HA cluster with 8 or fewer hosts (vSphere 4.0 Update 1)
145 powered on Linux VMs concurrently scanned per host
145 powered on Linux VMs concurrently scanned per VUM server
145 VMs per host scanned for VMware Tools
145 VMs per host scanned for VMware Tools upgrade
145 VMs per host scanned for virtual machine hardware
145 VMs per host scanned for virtual machine hardware upgrade
145 VMs per VUM server scanned for VMware Tools
145 VMs per VUM server scanned for VMware Tools upgrade
100 VMs per host in HA cluster with 8 or fewer hosts (vSphere 4.0)
72 powered on Windows VMs concurrently scanned per VUM server
40 VMs per host in HA cluster with 9 or more hosts
10 powered off Windows VMs concurrently scanned per VUM server
6 powered on Windows VMs concurrently scanned per host
6 powered off Windows VMs concurrently scanned per host
5 VMs per host concurrently remediated
Got all that?
Update 5/10/10: Added the row 160 VMs per host in HA cluster with 8 or fewer hosts (vSphere 4.0 Update 1) – Thanks for the catch Matt & Joe!
I just read that PDF this morning… interestingly only 6 Windows VMs vs 145 Linux VMs scanned per host. Why?
Shouldn’t it be 160 per host in HA cluster with 8 or fewer hosts… with Update 1 anyways.
Hello,
Great quick reference. Just thought I’d point out that that in 4.0 Update1:
“100 VMs per host in HA cluster with 8 or fewer hosts”
has become :
“160 VMs per host in HA cluster with 8 or fewer hosts”
