View ArticleStorage Array - Performance Knee
Good morning. We're an SMB-sized governmental entity (10 hosts and <100 VMs) and we're finalizing a list of storage solutions (EMC VNX, HDS HUS, NetApp FAS, Tegile HA21xx and X-IO ISE-2) to replace...

The idea is rather silly I think. Each configured array has it's particular capabilities - if the solution is properly designed then you will not experience anything like this. If you choose an array...

I ran some perf tests on my production environment on both my md3200's. The test ran for 24 hours (including Veeam backups). I'll post some more findings on a few arrays: host 16 x 600gig 15K 3.25 raid...

I know, it sounded like FUD to me too, but thought I would sound out the community on this one. We are looking at the 3PAR 7400 too, but their pricing doesn't seem to be that competitive with the...

What is the benefit of allocating multiple VMs in one datastore?
Hi, Quite a stupid and basic question but I cannot answer it . What is the benefit of having multiple VMs in one VMFS datastore instead of having each VM in one different VMFS datastore? (eg. 3 VMs in...

Fewer LUNs/Volumes also keeps administration a bit easier on the VMware side. There are also the "LUNS per server" limits listed in the Configuration Maximums.

1)management - having a datastore for each vm just does not scale. If the virtual system is very small, you COULD do that - but, why?2)performance efficiency - few vms require dedicated storage - to do...
View ArticleRe: What is the benefit of allocating multiple VMs in one datastore?
By allowing multiple VMs into one datastore, you can run more than 256 virtual machines in a DRS cluster.As a Host has a limit of 256 scsi IDs that means it can access no more than 255 shared luns. 1...
