Hi, We have existing VNX storage connected to the Brocade SAN switches. (no free ports available on Brocade SAN Switches) We have procured new AFF400 and Cisco SAN switches. Our objective is to migrate the data from VNX to NetApp. Please help on how can we achieve this. Can ISL be done between OLD Brocade and New Cisco SAN switches. From VNX the LUN are mapped to Windows servers Viren

Hello. I have a question about the system manager. When I download the performance of the system manager, there are read, write, and other parts. However, the proportion of other in the IOPs portion of our customer's data is applied too large. What does the value of other mean? In addition, from which value can the latency value be considered to be delayed? When monitoring latency values, at what point should I tell the customer that it can affect them?

Hi, I was trying to locate information on the power requirements/typical draw for A900 controller and NS224 disk shelf so I can properly size the power feeds for the entire rack. All I was able to find in the available documentation is the combined power draw for a A900 configured with a single NS224 shelf? I'd really appreciate if anybody out there could share any info.

Need some help with a FAS2520 2-node switchless cluster. Since some time one of the nodes appears in red (node down) in OnCommandSystemManager. Here's some commands output that I've managed to run (I'm a NetApp newbie, hope these make sense):

I've tried to reboot the failed node from command line, but:
ntapcl-bul-sf::*> system node reboot -node ntapcl-bul-sf-01 Warning: Rebooting or halting node "ntapcl-bul-sf-01" in an HA-enabled cluster may result in client disruption or data access failure. To ensure continuity of service, use the "storage failover takeover" command. Are you sure you want to reboot node "ntapcl-bul-sf-01"? {y|n}: y Warning: Unable to list entries on node ntapcl-bul-sf-01. RPC: Couldn't make connection Error: command failed: RPC: Couldn't make connection
Looks like a communication issue, there is no ping to any of the IPs of the failed node - not from a workstation, not from the second node.
What would be the right thing to do next? Is it safe to turn the power off/on , or reconnect all network cables one by one? Or something else?
Thanks in advance for the help!

Hi Team we have an issue on one of our netapp appliances. One of the controllers keeps faulting every 2 days. Only a hard reset seems to solve the issue temporarily. Some of the resources do stay online but the rest do not failover to the other controller. kindly Advise
