RE: VMWare RAID 10 or Raid 5
Indeed we are slowly moving towards RAID6 On some of the EMC Systems we have here. From: Joseph L. Casale [mailto:[EMAIL PROTECTED] Sent: Monday, June 23, 2008 9:16 PM To: MS-Exchange Admin Issues Subject: RE: VMWare RAID 10 or Raid 5 Just an opinion, but if your going that route, use Raid 6 if your controller does it. Your scenario puts you in jeopardy the moment one drive fails, as during the rebuild your not redundant. In Raid 6, two can go and bring you down to zero ft which is no worse than what you would have your way accept it can happen faster without loosing it all. jlc From: Garcia-Moran, Carlos [mailto:[EMAIL PROTECTED] Sent: Monday, June 23, 2008 1:54 PM To: MS-Exchange Admin Issues Subject: RE: VMWare RAID 10 or Raid 5 Haha yup sorry bout that, Webster is correct 8 Drives Plus One Hot Spare, all Fiber 15K From: Webster [mailto:[EMAIL PROTECTED] Sent: Monday, June 23, 2008 3:16 PM To: MS-Exchange Admin Issues Subject: RE: VMWare RAID 10 or Raid 5 From: Rob Bonfiglio [mailto:[EMAIL PROTECTED] Subject: Re: VMWare RAID 10 or Raid 5 Is it safe to assume that you meant RAID 5+1?

I have 56 spindles -Original Message- From: Jason Gurtz [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 24, 2008 9:13 AM To: MS-Exchange Admin Issues Subject: RE: VMWare RAID 10 or Raid 5 Indeed we are slowly moving towards RAID6 On some of the EMC Systems we have here. Just for my overall perspective on this Raid6 topic: Like anything else, it's a tradeoff. In this case yet another performance hit for peace of mind. I wish I could remember the exact formulas and numbers, but the basic idea is that the chance of failure while rebuilding increases with the amount of spindles and volume size (length of time to rebuild). A little research should turn up the numbers, but I think I feel safe saying if there's less than 8 drives the RAID6 perf penalty probably isn't worth it. Of course, every situation is different and one must consider the value of the data, backup strategy in place, recovery time, etc... On the other end, if spindles goes more than 15-20 or so, you would probably start looking more at layered raid levels like 50 or even 60 to increase redundancy and perf at the cost of storage space and $.

VMWare RAID 10 or Raid 5
I am looking at installing VMWare in my environment. For about 20 -30 users at this point. Have any of you implemented it on a raid 5? I don't envision anything too intense for useage but if you could give me feedback on your experience using vmware on raid 5 or raid 10 and your preferences. obviously it depends on what i am running - exchange and some small databases in this case.

Re: VMWare RAID 10 or Raid 5
At some point yes ...a SAN would be justified. performance is more important at this point. My next thought is to eventually move to a SAN. when may depend on the size of my disks. but really want to see if RAID 10 is worth the sacrifice of space. - Original Message From: Andy Shook [EMAIL PROTECTED] To: MS-Exchange Admin Issues exchangelist@lyris.sunbelt-software.com Sent: Monday, June 23, 2008 11:49:36 AM Subject: RE: VMWare RAID 10 or Raid 5 Thinking long term, would you rather have space or performance?

RE: VMWare RAID 10 or Raid 5
If you want to go RAID10, do you have enough space for all your VMs + growth needs? If so, go RAID10, if not go RAID5, I don't think you'll notice much given the size of implementation.
