•
SATA II drive interface (Backward-compatible)
•
Configurable N-way mirror for high data protection
•
On-line volume expansion with no system down-time

Extensible APIs for host server integration
When properly configured,
RAC 141
provides non-stop data storage
service with a high degree of fault tolerance through the use of RAID technology
and advanced array management features.
RAC 141
connects to the host system through an U320 SCSI interface
for optimized performance in speed. It can be configured to any RAID level to
provide the most reliable data protection and fastest data transfer rates as
required by user applications.
RAC 141
is designed with a new level of polynomial technology to
implement the RAID 6 function. RAID 6 arrays allow up to two simultaneous HDD
failures without impact on the existing data, making the
RAC 141
the
most reliable RAID system.
RAC 141
has
SNAPSHOT
feature that can perform an online speedy
logical data backup on the controller level without affecting the performance of
the server host.
RAC 141
offers array migration and expansion technology to give users
the flexibility to change RAID levels and increase array capacity for increased
performance or data security to meet the changing demands of applications.
RAC 141
is the most cost-effective disk array subsystem with
