AX150 with 1Gb FC-Switch - no_sync-Problem

Question

Hello List,

I have 2 FSC-Server and 2 AX150.
To connect all devices, I use a Compaq 16-EL with FW 2.6.2d.
I see 4 HBAs (2 from each FSC-Server), but all Raid-FC-Connections have no_sync state.
Is the AX150 (2Gb) able to talk to slower FC-Devices (1Gb) ?

By the looks of your settings, I'd say - No does not look like it will communicate so slowly.
Just worth a look though, have you tried setting the switch ports to AutoNeg? - perhaps you will get lucky.

In the mean time though - FC switches are not to dear these days so may be worth investing. Failing that - you can always direct connect from the San's SP's to the Servers HBA's, ignoring the switch altogether. Granted - you may need two HBA's per server and each HBA may be a single point of failure, but your switch would have been a Single point of failure anyway.

So -
Ideal - buy two cheep 2gb switches, ensure 2x 2gb hba's per server and cross cable for redundancy.
OK - buy a single 2gb switch, ensure a minimum of 1x2gb hba per server (no redundancy)
Just get it working - ignore switches, ensure 2x 2gb hba's per server and direct cable to a single Stroage processor on each of the two arrays.

Hope this helps.
