Connecting to SAS Devices
The SAS-NEM module, mounted in the back of the chassis, allows to the Sun Blade
X6450 Server Module to connect to SAS devices inside the chassis and outside of the
chassis. Each chassis can support one or two SAS-NEM modules.
These configurations require the Sun Blade X6450 Server Module to have either a
REM or a FEM.
■
Inside the chassis, the Sun Blade 6000 Disk Module provides eight SAS drives.
The Sun Blade 6000 Disk Module and the Sun Blade X6450 Server Module work
in pairs, with the server module in an even-numbered slot, directly to the left of
the disk module. Thus, the pairs can be in slots 0+1, 2+3, 4+5, 6+7, or 8+9.
In this configuration, the eight disks on the disk module are available to the
server module, and appear in the boot list as local drives.
■
Outside the chassis, the Sun Blade 6000 10GbE Multi-Fabric Network Express
Module provides four 10 GbE SAS external ports as well as connections to the
Sun Blade 6000 Disk Module.
For more information, see the Sun Blade 6000 Disk Module Installation Guide (820-
1702), and the documentation for the corresponding SAS NEM module.
The following device requires software 3.0 or newer.
