SAN recommendation for VSPhere Essentials Plus
Posted on 2014-08-31
I got quotes for new server hardware (2 hosts and 1 SAN array for VSphere Essentials Plus) and I would like to get some opinion on the SAN’s I am being quoted as price wise they are all very close to each other (each quote is based on the results of a Dell DPACK analysis). The main requirement that everyone got was that our ERP system requires a separate RAID 10 array with at least 15k drives.
1. HP MSA 2040 (iSCSI) with 16x600GB 10K drives 4x200GB SSD drives. One thing to note here is that the vendor is ordering the array without disks. They are ordering Western Digital SAS and Samsung SSD Disks so the HP warranty/support will not cover those.
2. EMC VNXe3200 (iSCSI) with 24x300GB 15k drives. They are not guaranteeing that our switches (Dell Powerconnect 5548) will work.
3. Dell PowerVault MD3420 (SAS Connected) with 16x600GB 10k drives, 4x300GB 15k drives and 1x800GB SSD for cache.
The performance on all 3 should be more than enough as we currently run everything (except our ERP) on a NAS with 7.2k drives.
So far I prefer the Dell Quote as it has the SSD Cache and uses a SAS connection so I don’t have to worry about our switches supporting the SAN.
Thanks in advance for any feedback.
