I now have the 2240 in production but it hasn't been a breeze. Problems found are as follows: -
1. If your private subnet range for ACP is in the same class as your SP, the SP will not route to a subnet outside of its subnet. I.E. Live network 192.168.30.0/24, ACP network 192.168.0.0/26 will clash even though subnet masks ensure different subnets. You have to change ACP to say 10.0.0.0/26.
2. The Autosupport SMTP can be a little flakey as there is a bug that prevents a SMTP session to terminate correctly after a message is sent.
3. We have only managed to get with Autosupport set to HTTPS through SMTP a Simple report and not full report. This is still with Netapp support. (We have tried both our Exchange and Linux smtp servers). I believe only Linux Sendmail will SMTP correctly in 8.1 RC from reading the bug report.
4. We had an issue that an aggregate was created with a 11 disk RAID set, luns were created and then later another 11 disks were added and re-allocation run on both aggregate and luns and the performance ended up to be 3000 IOPS on the Luns when another aggregate was showing 14,000 IOPS on the same amount of disks. We had to remove and re-create Luns to get the speed back!
5. There have been some serial numbers shipped due to a Oracle to SAP conversion within Netapp that aren't registered at Netapp (including ours!). This stops you using autosupport and can cause mass confusion as the support contract is assigned to completely different Serial numbers meaning a lot of automated tools from now won't work. Netapp are onto this as it is a global issue.
Apart from this fingers crossed it seems quite good. I have pulled all sorts of cables to test failures and it seems solid as a rock.
