Enclosure Features
The HP StorageWorks Modular Smart Array 20 (MSA20) is an Ultra320 host
connect disk drive enclosure that uses Serial ATA (SATA) drives. The MSA20
delivers a low-cost, high-capacity solution that is suitable for minimum I/O workload
situations such as storing reference data, archiving files, and performing disk-to-disk
backups.
You can connect the MSA20 to the external port of any sixth-generation Smart Array
controller or to an MSA1500 controller shelf (MSA1500 cs). These external
controllers enable you to configure the SATA drives in the MSA20 with RAID levels
of 0, 1+0, 5, or ADG.
The MSA20 also has an internal controller module with a battery-backed write cache.
The cache allows data to be transferred rapidly to the SATA drives, and the batterybacked feature protects data held in the cache for up to four days if power to the
enclosure is interrupted.
The enclosure components incorporate some important safety and redundancy
features. For example, if one power supply unit fails, the remaining functional unit
can temporarily provide enough power for a fully equipped enclosure. Similarly, if
one fan fails, the remaining fan runs at a faster speed, and can temporarily provide
enough cooling for a fully equipped enclosure. In either case, replace the failed
component as soon as possible to maximize the life expectancy of the remaining
power supply or fan.
For more information about features of the MSA20 enclosure, refer to the HP
website,
