Re: Upgrading to 2780 I/O Controllers

[Jeff Kennedy <jkennedy@xxxxxxxxxxxxx>]

We are running a 2757 on our 810 (V5R2).  The early 2757 had a problem 
and we replaced. There are PTF's for V5R2 to let you check the 2757 
through SST. The 2780 is the same card with Read Cache added, probably 
only helpful for Windows or LINUX.
