Figure 22 HP 3PAR StoreServ 10000 Controller Node Numbering
T-Class Controller Node Numbering
T-Class systems contain two, four, six, or eight controller nodes per system and only use T-Class
controller nodes. Controller nodes are loaded into the system backplane enclosure from bottom to
top.
For a T800 storage system with only two controller nodes installed, those controller nodes would
occupy the lowest 4U of the backplane and would be numbered node 6 and node 7.
A controller node takes on the number of the bay that it occupies in the system backplane, as
shown in Figure 23 (page 70).
