RAID expansion modules (REMs) provide host bus adapter (HBA) functionality on some blade servers. They mount to a REM connector on the blade motherboard and are supported as follows:
SAS-1 REMs provide up to 3 Gb/sec data transfer rate and are supported for use with server module internal disks and disks in a SAS-1 disk blade when used in a chassis with SAS-1 NEMs.
When used in a chassis with SAS-2 NEMs, they are supported for use only with a server module's internal disks.
SAS-2 REMs provide up to 6 Gb/sec data transfer rate and are supported for use with server module internal disks and disks in a SAS-2 storage blade when used in a chassis with SAS-2 NEMs. When used in a chassis with SAS-1 NEMs, they are supported for use only with a server module's internal disks (note that other SAS-1 devices in the chassis might require a firmware upgrade to support this configuration).
SAS-2 REMs are required for a server module to work in a SAS-2 chassis environment. Refer to the server module documentation to determine whether or not SAS-2 REMs are supported.
The following illustration shows a REM being installed on a Sun Blade X6450 server module.
The following table lists the REMs and links to the available REM documentation. The REMs listed here were available at the time this topic set was last updated.
