Hello,
We have been using Netapp FAS 2040 in HA mode with 2 Controllers. And having 33 Disks (500GB/1TB/2TB)s providing effective Size of 11 TB. Netapp operates on 1 GB Network with NFS connectivity.
We are looking for a new mid-range solution as the Model FAS2040 is out of warranty and support. The recommendation we received is FAS 2720 with ( 12 x 2 TB) disks.
1. Firstly I would like to know if this suggested upgrade is practical? Has anyone experience using this model FAS2720 or FAS2700 Series?
2. I feel 24 TB will be not sufficient, considering the fact that Netapp's RAID-DP will have 3 Disks reserved plus there will be some disks kept in reserve as well. So lets says 3 Disks for reserve and 3 for RAID-DP , giving approximate size of 6 or 7 x 2 TB ~ 14 TB. I feel then we should go for 4 TB Disks giving us, 12 x 4 TB ~ 48 GB or effective 6 x 4TB = 24 TB Size.
I would appreciate your comments/suggestions on this topic. I am currently reading the datasheet of FAS2720.
I would update this case with more questions as and when required. Thanks in advance.
Regards,
admin
