Chapter 
Replacing a SAS Extender or SAS Expander
This server has two factory-configurable options for hard drive backplane connection: the standard SAS 
extender or the optional SAS expander. 
Note The extender and the expander are field-replaceable, but you cannot upgrade an extender to an expander 
after-factory.
The SAS Extender
The SAS extender is installed standard in this server.
Figure 3-22 SAS Extender
 
  • The extender supports connection for up to eight drives. Connector 1 provides connection for drives 
1–4, connector 2 provides connection for drives 5–8. See 
Supported RAID Controllers and Required 
Cables, page C-1 for the required cables.
  • To control more than eight rives, your server must have the optional expander.
The SAS Expander
Note The SAS expander cannot be used with the onboard ICH10R controller. You must use a RAID controller 
card with the SAS expander.
Figure 3-23 SAS Expander
 
  • The expander supports connection for up to 16 drives when using a single LSI MegaRAID 9261-8i 
card. See 
Supported RAID Controllers and Required Cables, page C-1 for the required cables.
  • The expander has two mini-SAS SFF-8087 cable connectors. One connector provides connection 
for up to 16 drives, and the second connector provides redundancy.
