RAID card

This topic provides information to help you locate the connectors on the RAID card if a RAID card installed
is in the longer slot of the riser card assembly 1.
Some server models come with a RAID card to provide advanced SATA/SAS hardware RAID functions. You
also can purchase a supported RAID card from Lenovo and install it into the server. See "Installing or
removing the RAID card" on page 107.
Notes:
• The option kit for a RAID card is designed for different types of servers and might contain additional
cables that are not required for your server.
• The server must have a RAID card and an expander card installed to support more than eight hard
disk drives.
Your server supports the following RAID cards:
• ThinkServer RAID 500 Adapter (also known as ThinkServer 9240-8i RAID 0/1 Adapter)
• ThinkServer RAID 700 Adapter (also known as ThinkServer 9260-8i SAS RAID Adapter)
• ThinkServer RAID 710 Adapter (also known as 9270CV-8i RAID adapter)
