IBM Power System E850C: Technical Overview and Introduction
2.12.2 EXP24S common usage scenarios
The EXP24S drawer is versatile in the ways that it can be attached to Power Systems. This
section describes the most common usage scenarios for EXP24S and Virtual I/O Servers,
using standard PCIe SAS adapters (#5901).
Scenario 1: Basic non-redundant connection
This scenario assumes a single Virtual I/O Server with a single PCIe SAS adapter #5901 and
an EXP24S set on mode 1, allowing for up to 24 disks to be attached to the server.
Figure 2-27 shows the connection diagram and components of the solution.
Figure 2-27 Scenario 1: Basic non-redundant connection
The following are the required feature codes for this scenario:
One EXP24S drawer #5887 with indicator feature #9359 (mode 1 with single #5901)
One PCIe SAS adapter #5901
One SAS YO cable 3 Gbps with proper length
Note: Not all possible scenarios are included. See the “Planning for serial-attached SCSI
cables” guide in the IBM Knowledge Center to see more supported scenarios.
