Today we received a Violin Memory 3140 Flash Memory Array in our lab for testing. This device is basically a SAN made out of flash memory and is said to be capable of 200,000 IOPS.
It uses Fibre Channel as the storage protocol (it can also do iSCSI) and the only Fibre ports we have in our lab are on our UCS Fabric Interconnect. I thought that this would be no problem since Cisco released Firmware 1.4 for the fabric interconnects which allows direct connection of Fibre Channel devices to the Fabric Interconnect. I connected the cables changed the port type to “Configure as FC Storage Port”… the ports changed immediately to Administrative Down. After searching for a couple hours to find the procedure to enable direct connection of the fibre channel devices I finally found it on this blog. The Fabric Interconnect needs to be set to “FC Switching Mode” and “Enable Default Zoning” needs to be selected on the VSAN that is configured for the FC ports.
