Replacing a SAS Extender or SAS Expander
This server has two factory-configurable options for hard drive backplane connection: the SAS extender
or the 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
Figure 3-20 shows the SAS extender.
Figure 3-20 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 3-20 shows the SAS expander.
Figure 3-21 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.
