Controller Node Overview
InForm OS Version 2.2.4 3PAR InForm OS Concepts Guide
The number of host ports each storage server model can accommodate is summarized in
Table 13-3.
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 13-1 on page 13.4 for an example of controller node numbering in
an InServ T800 Storage Server fully populated with 8 controller nodes.
Table 13-3. Storage Server Models and Number of Ports
Storage Server Model Number of FC Ports Number of iSCSI Ports
InServ S400 and T400 0-64 0-16
InServ S800 and T800 0-128 0-32
InServ E200 and F200 0-8 0-4
