Redundant elements to enhance fault tolerance
DNAS units feature a number of redundant elements to
enhance the operational fault tolerance of the units. These elements include redundant hot swap power supplies, and
online spare hard drives.
Unlike traditional RAID systems with their limitations as to cabling and the number of PCI slots e.t.c.
DNAS, units can be scaled infinitely, you can start out with 144GB unit and scale to 8000GB.
DNAS features an advanced file system and volume manager which allows the addition of extra storage
without the need for rebuilding raid. Storage can be added and become instantly available.

The systems are designed from the ground up, to optimize I/O processing. Unlike traditional servers
which are designed as general purpose computers, and are typically running a large operating system
which has to share the workload among competing tasks, DNAS units only do one thing: move data off
the disks as fast as possible. DNAS units come equipped with multiple channels for I/O processing.
The installation of a DNAS system on a network usually leads to an improvement in general network
performance as they offload a lot of typical server processing. DNAS units allow servers to concentrate
on running applications such as database, messaging etc rather than managing file I/O. The network
performance of DNAS units can be further enhanced via the addition of extra network ports on the
DNAS units. The standard ethernet based DNAS unit can have the number of network ports (NICs)
increased from 1 to 6, a GIGABIT , ATM, Fibre Channel or Firewire option is also available.
