This is my small home/office system. I got it from ghetto shop (aka ebay), so i don't have Netapp support to ask questions.
I have FAS3220HA with 8.1.4 7-mode and 1 ds2246 shelf with 24x600gb sas, 4x 400GD SSD. Also i have some spare ds14mk shelfs with FC drives.
I could get one more ds2246 shelf and more SAS drives if needed for superconfig 😄
What would be recommended config for drives/shelfs?
1) Is it ok, to mix SAS and FC shelves? (i could uses FC shelf for both root volumes) Is this idea normal? What is bad with this idea it is fact that i can have only single link to fc shelf because on controller i use other FC pair (1 from each controller) for data.
2) Is 4 SSDs enough to make flash pool in ds2246 with 4ssd+20sas? Or is it better to have 5ssd and then have 2data+2par+1hs (ssd) (yes, i remember that 8.1 can have only 500gb for flash pool, but i could upgrade to 8.2 with 1.5TB flash pool size) + 16data+2par+1hs (sas)
Holy war raid-4 vs raid-dp?
3) Maybe its better to have 1 root + data + flashpool on ds2246 and other root + slower data on FC shelf? On the other hand i will loose SAS spindles that will be used for root aggregate 😕
In general, what would be community recommendations on how to setup drives?
