Note: Four power modules are required in the BladeCenter S chassis if both disk
storage modules are installed.
To access the hard disk drives in the disk storage module, SAS RAID controller
modules must be installed.
Note:
1. SAS RAID controller modules must be installed, one in I/O module bay 3 and
the other in I/O module bay 4. Each SAS RAID controller module will have
access to both disk storage modules (for high availability).
2.
Mixing one 2.5-inch disk storage module and one 3.5-inch disk storage module
in a BladeCenter S chassis is currently not supported.
There is one LED on each disk storage module:
Fault Solid (amber) when there is a disk storage module failure.
There are two LEDs on each hard disk drive:
Green Flashing when an operation, such as a read or a write, is being performed.
Flashing when the hard disk drive is being rebuilt (fast blink) or identified
(slow blink).
Note: When power is restored to the BladeCenter S chassis after a
complete loss of power and you have implemented the hard disk drives as
a redundant array (RAID 1, RAID 10, RAID 5), the green light will blink as
the hard disk drive is being resynchronized.
The redundant array is accessible during resynchronization although
performance may be slightly slower.
