In short:
*) X6729A is not supported on V880, use X6799A instead;
*) To connect X6799A HBA to the switch, use an SC-LC cable;
*) To connect a T3+ to the switch, use an LC-LC cable;
*) Use an SFP to connect the "LC-end" of the cable to the switch;
Million thanks to Drew Skinner, David Livingston and E. (NO UCE)
for the following:
Drew Skinner pointed out that the master of a T3+ partner pair
would shut down both arrays if you fail to replace a FRU (a disk)
within a certain time frame, and that in his opinion it's better if
the T3+s are mirrored using SDS or similar software.
David Livingston pointed out that I will need SC-LC cables to connect
the HBAs to the switches, LC-LC cables to connect the T3+s to the
switches, and SFP (370-5211) modules to connect the LC-end of the cables
to the switches.
E. (quote) "throwed a spanner in the works" by pointing out that X6729A
isn't supported on USIII or higher CPU systems (this includes V880).
Actually, this saved me a lot of grief, thanks, E!. Also, confirmed what
cables I need.
A great list, this is!
