Description
The Sun StorEdge[TM] 3310 SCSI Array is capable of 160-Mbyte/second performance, but performs at only half speed (maximum throughput is 80 Mbyte/second) when it is attached to the Sun Fire[TM] V440 server's external SCSI port.


Steps to Follow
This issue only applies to arrays with firmware revision level 3.25Q or earlier. To check what the firmware level is do the following:

 ok probe-scsi-all
