All,
I'm setting up a new 7133 drawer and need some advice on cabling. Our
current drawer is connected to two adapters. 2 RAID-0 stripes, and an AIX
mirror. Is the correct cabling? It's been running in production like
this for years:
SSA1 7133 SSA2
B2 4 |-- 1 B2
|
B1 5 | 16--| B1
| |
A2 ---- 8 | 13 |--A2
|-------
A1 -- 9 12 A1
| |
---------------
So on the 1st adapter, A2->8, A1->1, 2nd adapter A2->16, A1->9.
For the new drawer, i'd like to do RAID-10 in hardware. It's also connect
to two separate adapters. The first config i did looks like this and
seems to work fine:
1st adapter A2->8, A1->9, 2nd adapter A2->1, A1->16.
But the "Understanding SSA Subsystems" book seems to suggest this cabling
for a "Simple loop with two adapters":
1st adapter A2->8, A1->9, 2nd adapter B2->1, B1>16.
Any advice as to which is more correct?
