The NSS3U16SA-FC SAN-ready subsystem combines the cost-effective SATA drives in a high availability 4G FC array. IT managers will find it is an easy-to-use and easy to maintain storage solution for their DAS, Fibre Channel SAN and clustered servers or any application requiring dedicated bandwidth.
The NSS2U12SA-SI & NSS2U8SA-SI feature
reliable SCSI host interfaces and large, cost-effective SATA disk
drives. The series models are ideal for building a shared storage
pool for data backup in the digital media, broadcast, medical
imaging, and security/ surveillance environments.

IOSmart
IOSmart allows for the
flexible configuration of logical drives,
logical volumes and logical partitions and
ensures instant RAID availability via background
logical drive initialization. Fibre loops' load
balancing is provided within the subsystem. The
firmware's embedded intelligent algorithms, such
as Adaptive Write Policy and Guaranteed Latency
I/O, improve sequential write performance and
ensure the fast and continuous flow of data.
DrvSmart
The DrvSmart utility provides
an easy way to store data while keeping it safe.
One of the main DrvSmart functions, Media Scan,
retrieves data from degraded or damaged hard
drives and handles low quality drives in both
the degraded mode and during the rebuild
process. Other DrvSmart features include disk
cloning, drive roaming, SMART, transparent
resetting of non-responsive hard drives, and
RAID parity update tracking and recovery.
SysSmart
SysSmart combines enclosure
monitoring and firmware management capabilities
in order to minimize the chance of down time
caused by hardware failures. The Auto data
protection mechanisms are developed to ensure
data safety. Other SysSmart functions include
the event-triggered and the various monitoring
utilities and monitoring approaches combined
with the powerful RAIDWatch manager. Component
status, voltage and temperature readings, and
system events are instantly revealed through the
manager's graphical interface.
