I am evaluating new file storage, Hyper-V virtualizaiton and deployment of exchange 2010 standard (moving from 2003 standard). Ultimately, it sounds like we need a SAN, however due to cost reasons, I'd like to stay with NAS if possible. Environment is 100% Windows with approximately 100 users.
We currently have 2 physical DCs, 1 physical Exchange (60GB DB), 2 physical servers (combined file data 600GB), BES 5 running on ESXi 4, Business Contact Manager 2010 running on the same ESXi box. Additionally we have Symantec End Point running on Microsoft Virtual Server 2005 r2 .
My original thought was to go with HP Storageworks x1600 G2 6TB SAS model - BV864A, 2 HP switches E2910-24F - J9145A#ABA and 3 x DL 380 G7 639829-005 boxes (also ordering 12 x 4GB DDR 1333Mhz RAM). The problem with this idea is that all of my eggs would be in one basket. The other issue is the IOPS, so I'm choosing a NAS with approximately 10 x 600GB SAS 10K drives, plus I'm getting 6 more 600GB SAS for use in same storageworks or in exchange if we decide to go with physical Exchange and Local storage.
If we use HP Storageworks x1600 G2, I can eliminate 2 servers as I could just combing File Servers directly on the Windows Storage Server 2008. Convert to Hyper-V following machines: SEP, BES 5, build a new VM for accounting, possibly virtualize Exchange... But I also would like to provide some form of replication/redundancy.. Netgear offers ReadyNAS where you can replicate the 2 NAS boxes, am I able to do the same with Storageworks without 3rd party software ? Yeah, backing up is one thing, but when you have everything running on one NAS, we need some form or replication so if one box goes South, we are still fully functional on another one.... My concern with ReadyNAS is that it uses SATA and I’d like to stay with SAS.
Backing up VMs, I would probably use SCVMM or perhaps something else….
Dell recommended EqualLogic, 3 x R710 and 2 switches, but the cost of EqualLogic = 2 x Storageworks Units with 6TB SAS in each… Even with a SAN, I would still have everything in one basket….
I'm attaching results from Dell tool that we ran for 24 hours, it shows total storage including the OS and everything, realistically my file storage is 600GB, exchange is 60GB and my utility directory is 200GB, not including the actual VMs currently....
Any suggestions or recommendations ?
Sorry for a long post....
