Introduction
22 MSA1000 Reference Guide
System Power
Power to the MSA1000 does not shut off completely with the power switch. The
two positions of the front panel power switch should be considered as on and
standby, instead of on and off. The standby position removes power from most of
the electronics and the drives, but portions of the power supply and some internal
circuitry remain active.
Consequently, to remove all power from the MSA1000 storage system, you must
disconnect the power cord from the storage system. In environments with multiple
power supplies, you must disconnect all power cords to remove power completely
from the MSA1000 storage system.
WARNING: To reduce the risk of electric shock or damage to the equipment,
disconnect power from the storage system by unplugging all power cords from
either the electrical outlet or the storage system.
Maximum Storage
A maximum of 14 1-inch Universal drives can be installed in the MSA1000. Up to
two additional external storage enclosures can be cascaded from the MSA1000,
expanding the capacity to 42 drives.
Refer to the MSA1000 website:
www.hp.com/go/msa1000 , for the most up-to-date information on supported drives
and enclosures.
Note: The maximum size of a logical unit is 2 TB. If you have more than 2 TB of
storage attached to your MSA1000, you must create multiple logical units.
SCSI ID Assignments
SCSI IDs are assigned automatically in the storage system according to the drive
bay used for each drive. It is not necessary to assign SCSI IDs manually. Drive
bay numbers are indicated on the front panel. See the “SCSI ID Assignments”
appendix for a complete table of SCSI ID assignments.
