■ Cache Protector takes care of the cache in case of
power failures without the limitations of traditional
battery solutions.
■ Redundant Copy solves the problem of dangerously
increasing recovery times within a RAID group by
copying the data before the drive fails.
■ Data Block Guard helps to ensure data integrity both
on the disk and in the cache via the check code.
■ RAID Migration makes it easy to manage different
storage tiers by moving LUNs dynamically between
different RAID groups.
■ SAS and Nearline SAS hard disk drives as well as
high-end Solid State Drives offer the optimal mixture
of performance and capacity. In addition, Nearline SAS
drives have the capacity and low cost of SATA drives,
while using the enterprise SAS interface which is more
reliable, feature-rich, dual ported and faster.
■ Eco-mode reduces energy consumption and heat
dissipation by using MAID functionality, which
»spins down« your idle drives.
■ Main components such as power supply unit, hard
disks and RAID controller are redundant and hotpluggable.
Redundant Copy
rebuilds a disk automatically out of the parity information of the RAID group, as soon as the first
signs of failure appear. In most cases, Redundant
Copy helps to pro-actively replace a disk before it
actually breaks. This dramatically minimizes the
risk of permanent data loss.
Cache Protector
uses capacitor technology instead of batteries to
write the RAID controller cache to non-volatile flash
memory during power outages. The cache data is
secured for an unlimited time and does not depend
on battery capacity. The array can return to high
performance mode within minutes after restore.
Furthermore, capacitors do not need as much maintenance, and have a longer lifespan than batteries.
