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.
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 SAS expander firmware of your SAS-1 NEMs and Sun Blade 6000 Disk Modules to a version that supports SAS-1/SAS-2 coexistence. The minimum SAS expander firmware required for SAS-1 NEMs and the Sun Blade 6000 Disk Module is 5.04.03. 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:
