Hi,

First time mounting netapp and not familiar with its storage concepts. We got a 12 disk fas2520 (600gb sas) with 2 controllers. We must to use it in 2 node vmware connected by iscsi. With the system setup tool I choose active/pasive  so its configure 3 disk to one controller and all other in the other one, this setup makes my available 2.7 tb usable I didnt use the option active/active becvause the usable space was even lower. Please is it like is?  from a 7.2 raw space i can only use 2.X.? I have read that netapp needs at least 3 disks per head but this not sounds good, as I usually works with SAN storage that can profit best the raw space no matter one or to controllers.
Im running 7-mode ontap with a switch dedicates for ISCSI traffic, is this the best approach? ISCSI is a must.
Greetings

You do not have enough disks, to do anything other than Active/Passive, if you want to maintain max storage with the disks you have available, so the Quick Setup program has done it's best.

Why iSCSI, as NetApp will recommend using it with NFS as performance is better!

You will need at least 3 disks allocated and owned by both controllers for HA operation. Which then leaves 6 disks left, which does not leave many to split between controllers, so I would allocate the remainder of the disks to controller A.

Then create your storage LUNs, or NFS Exports, and with HA functionining, in the event controller A fails, controller B will take over controller A.

Assign two IP Addresses to Controller A and Controller B, and setup multi path for iSCSI as per my EE Articles
