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.
There are two models currently in the 27xx series. the 2720 and 2750. the 2720 is the more entry level model, typically using SATA disks, where the 2750 is SAS/SSD typically.
We are currently having only SAS disks and was looking for both solutions 1. SAS and 2 SSD. So we got 2 offers . 1st for 2720 and other one AFF A200 HA with 24 x 960 GB SSDs. But the cost of it just goes beyound sky.
So its good to know that 2720 only supports SATA disks, otherwise I was thinking of asking for SSD disks for this model.
As far as sizing goes, either will work, the 4T disks will give you more room to grow, but do you plan on growing that much and is it worth the extra upfront cost?
If not 4TB then maybe lesser than that maybe 3 TB. But I really feel 12 x 2TB ~ 18 TB for 3-4 Years will not be sufficient.
I do not see exponential growth but atleast , 12 x 3 TB ~ 25-27TB should suffice for 5-10 Years.
