Sun Microsystems X6450 manual Solid State Disk Drive SSD, Connecting to SAS Devices

Solid State Disk Drive (SSD)

The SSD is a 32-gigabyte solid-state SATA drive that mounts on the motherboard.

Note – This feature requires a F540-7821-01 or newer motherboard, with 2.0 software installed. The motherboard part number appears on the motherboard, and can be read using the service processor.

When an SSD is present, it appears as a disk device, and you can install an operating system on it.

Note the following conditions:

■The SSD can only be driven by the onboard SATA controller.

■A server module with an SSD cannot have a Sun Blade RAID 5 Expansion Module.

■A server module with an SSD can have a Sun Blade RAID 0/1 G2 RAID Expansion Module, however it cannot drive the SSD.

For instructions to install an SSD, see the Sun Blade X6450 Server Module Service Manual.

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.
