We are a fairly straightforward user of the FAS2020. We utilize the iSCSI capabilities to connect the FC drives to our SQL and Exchange servers. The setup was pretty straightforward (running active/passive), but we are slowly running out of space. We were going to wait for the new SAS shelves, but I think that the combination of timing and pricing is going to send us back in the direction of a FC-SATA shelf.
The question I have is, how easy is the addition of shelfs to a FAS2020? I understand that I cannot mix drive types, but can I have FC-SAS drives in my FAS2020, and add a DS14 with FC-SATA drives in it? DS14MK4?
Will I need to shutdown my Netapp when I make the addition?
Is there a document on doing the upgrade that i am missing?
Any help in this area would be greatly appreciated!
The addition of an additional shelf will be very straightforward. Since you have SAS 15k rpm drives internal to the unit, you will want to purchase a DS14mk4 Shelf with Fibre Channel 15k rpm drives. You can add this shelf to the 2020 while it is online. Just be sure to connect the shelf to the FC ports on the controllers (one from each) and be sure they are active (they should be by default) before you power on the shelf. After power up, the drives should show as spares immediately and be ready to add to the aggregate.
(You would not want to add SATA drives, in this scenario).
correct, you need to have the right shelf type for the disk type of your choice and you cannot mix disk types in a shelf. Usualy the local netapp sales representative takes care of that when you request a quotation.
In both cases, S-ATA or FC, it will be attached with FC cables.
About the SAS stuff, NetApp now sells shelves with SAS technology, called DS4243 or DS4246 shelves, you cannot use these with a FAS2020.
