Upgrading the NEM to Allow a SAS-2 Compatible Server Blade in the Chassis

A P P E N D I X B

This appendix provides information on what is required to allow a server module with a SAS-2 RAID Expansion Module (REM) to function in a Sun Blade 6000 Modular System chassis that has SAS-1 NEMs, or SAS-1 NEMs and a Sun Blade 6000 Disk Module (which is a SAS-1 device).

Note - The easiest way to identify SAS-1 and SAS-2 devices is by the maximum data transfer speeds supported by the device. SAS-1 devices have a maximum data transfer speed of 3 Gb per second. SAS-2 devices have a maximum data transfer speed of 6 Gb per second. Refer to your device documentation for a list of specifications.

Server with a SAS-2 REM Might Hang When Inserted into a Chassis with SAS-1 Devices

If a server module with a SAS-2 REM is inserted into a Sun Blade 6000 Modular System chassis that has SAS-1 NEMs, or SAS-1 NEMs and Sun Blade 6000 Disk Module, the server’s SAS-2 REM might hang. To prevent this, you need to upgrade the firmware of your SAS-1 NEMs and Sun Blade 6000 Disk Modules to a firmware version that supports SAS-1/SAS-2 coexistence. This upgrade must be done before you insert a SAS-2 server blade into the chassis.

Available SAS-1 NEMs and disk modules that would require this upgrade include Oracle’s:

Sun Blade 6000 Disk Module (B18-AA)

Sun Blade 6000 Multi-Fabric Network Express Module (X4212A)

Sun Blade 6000 10GbE Multi-Fabric Network Express Module (X4236A)

Sun Blade 6000 Virtualized Multi-Fabric 10GbE Network Express Module (X4238)

An example of a SAS-2 server module is the Sun Blade X6270 M2. This server includes a SAS-2 REM. Available SAS-2 REMs include:

Sun Storage 6 Gb SAS REM RAID HBA (SGX-SAS6-R-REM-Z)

Sun Storage 6 Gb SAS REM HBA (SGX-SAS6-REM-Z)

Refer to your product documentation to find out if your server blade includes a SAS-2 REM.

For detailed instructions on performing the upgrade, refer to the SAS-1/SAS-2 Compatibility Upgrade Guide for the Sun Blade 6000 Modular System (821-1800) which can be found in:
