we would like to setup a new VI3 Infrastructure with the following HW-config. It´s not a consolidation project.
-126 VM guests ==> 90 % of the machines are Windows XP (it´s a customer request!)
-each should have 30 GB vHD ==> Sum 126VM x 30GB= 3780 GB
-512 GB RAM ==> Sum 126VM x 512MB= 64 GB
SAN EVA 8000==>
-9 VMFS, 9 LUNS (each about 450 GB) ??? or
-9 VMFS, 18 LUNS (each about 200 GB) ???
HP BL480c, 2P Socket Intel QuadCore 3 GHz, HBA, 4 NICs (1 for VMOtion, 1 Service Cons., 2 VM NIC-Teaming), 24 GB DDRAM , RAID 1 72GB SAS
Now I have to choices:
Constraint 16 VM per host ==> 12 x BL480c ??? Seems to be oversized in my opinion. Maybe 24 VM per host would be better.
Constraint 4 VM per core ==> 4 x BL480c ??? Seems to be undersized to me.
Is my sizing OK?
Would you constraint on VM guest per host or VM guest per core?
Thanks in advance!
9 LUNS sounds ok to me.
I'd be looking to get at least 25 vm's per host. But you need to consider the impact of a host failure.
VMware will support 11 instances per core if you're running VDI, otherwise 8.
