i have a 1U - HP DL360G5, 20GB of RAM
running windows vmware server 2.0
SAS array A has 2x72GB 10K SAS drives at RAID 1+0
SAS array B has 4x146GB 10K SAS drives at RAID 1+0
i have roughly 4-5 vms and the vms are running kinda slow and laggy. these are all test and development vms.
i have another DL360G5, running ESXi 3.5
SAS array A has 2x72GB 10K SAS drives at RAID 1+0
SAS array B has 2x300GB 10K SAS drives at RAID 1+0
that one has 5 vms running and is also a test vm host server, i do not notice the same performance issues that i see on the windows vmware server 2.
i would probably put the blame on the windows OS in general. i keep reading around the web about people saying do raid5 do not do rain5, blah blah blah.
i plan to scrap the windows box and start from scratch with esxi again. any recommendations how to proceed with the raid setup for esxi?
SAS array A has 2x72GB 10K SAS drives at RAID 1+0 (for the esxi os)
for the vm storage do i either do RAID 5 or stick with RAID 1+0
RAID 5 would probably be 4x146GB i would get about 400GB of usable space for vms.
SAS array B has 2x146GB 10K SAS drives at RAID 1+0
SAS array C has 2x146GB 10K SAS drives at RAID 1+0
so i would get 2 datastores at 137GB each?
or do i do 1 array at RAID 1+0 and get about 290GB of usable space?
most of the test vms are less than 40GB.
thanks for any input.
