Scenario 3: Dual Virtual I/O Servers sharing a single EXP24S
This scenario assumes a dual Virtual I/O Server with two PCIe SAS adapters #5901 each
and an EXP24S set on mode 2. This configuration allows for up to 12 disks to be attached to
each Virtual I/O Server. Figure 2-29 shows the connection diagram and components of the
solution.

Figure 2-29 Dual Virtual I/O Servers sharing a single EXP24S
The following are the required feature codes for this scenario:
One EXP24S drawer #5887 with indicator feature #9366 (mode 2 with quad #5901)
Four PCIe SAS adapter #5901
Two SAS X cables 3 Gbps with proper length
The ports that are used on the SAS adapters must be the same for both adapters of the pair.
This scenario provides no SSD support.
