Scenario 2: Basic redundant connection 

This scenario assumes a single Virtual I/O Server with two PCIe SAS adapters #5901 and an 
EXP24S set on mode 1. This configuration allows for up to 24 disks to be attached to the 
server. Figure 2-28 shows the connection diagram and components of the solution. 

Figure 2-28   Scenario 2: Basic redundant connection

The following are the required feature codes for this scenario:

򐂰

One EXP24S drawer #5887 with indicator feature #9360 (mode 1 with dual #5901)

򐂰

Two PCIe SAS adapter #5901

򐂰

Two SAS YO 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.

EXP24S – Mode 1 with 2 x #5901 (config indicator #9360)

#5901

SAS YO Cable
