Thanks for the reply. Here are my comments.
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.
Is the 2040 using any dedupe on the volumes?
What is this?
