13.5.1 S-Class and T-Class Node Numbering
13.5.2 S-Class and T-Class Controller Node Numbering
InServ S-Class and T-Class Storage Servers have 2, 4, 6, or 8 controller nodes depending on the
storage server model. The controller nodes assume the number of the bay they occupy in the
storage server backplane. The bays are numbered from 0 to <n>, from left to right, and from
top to bottom. See Figure 13-11 for an example of controller node numbering in an InServ
T800 Storage Server fully populated with 8 controller nodes.
InServ E200 and F200 0-8 0-4
InServ F400 0-16 0-8
