Overview of the Sun Blade 6000 Disk Module
The Sun Blade 6000 Disk Module is a SAS-1 (up to 3 Gb/s data transfer speed) disk module for the Sun Blade 6000 Modular System.
As a disk module, the Sun Blade 6000 Disk Module does not contain a CPU or service processor. It does, however, contain SAS expanders, which are switching circuits that can connect disks in complex patterns.
A fully loaded Sun Blade 6000 Disk Module consists of eight SAS disks, with each disk connected to SAS expanders. The SAS expanders, in turn, connect to a Sun Blade 6000 Modular System chassis’ SAS-NEMs.
The disk module works only with a SAS-NEM. It does not work with a NEM that lacks SAS connectivity. For the disk module to function, there must be a SAS-NEM in at least slot NEM 0. Dual paths to SAS disks require SAS-NEMs in both NEM slots.
Note - You can use a plain NEM (one without SAS connectivity) in slot NEM 1, but not in slot NEM 0. If you do this, you lose the redundant second path to SAS disks.
