DNAS
- Network
RAID system.
Features both direct connections to servers and Direct connection to network via 10/100 Ethernet, Gigabit
Ethernet, ATM
or Fibre Channel. Setup
and Administration can be done remotely via
a Java application.
FT-RAID
- Totally
Fault tolerant RAID System.
One of the few totally fault tolerant RAID Systems available on the
market. Unlike other RAID systems which claim redundancy, FT-RAID is
designed from the ground up for fault tolerance. Every component in
FT-RAID is duplexed. Most RAID systems which claim fault
tolerance suffer from the fact that if the back plane becomes faulty
the whole system will fail, even though they may have duplexed other
components. We know our competitors have very glossy brochures, but
the problem is hardly any have a true fault tolerant solution.
RAM-RAID
- Worlds fastest RAID System.
RAID system built from solid state RAM disks. Features 4 fibre
channel ports, delivering a total bandwidth of 400MB/sec throughput.
Access times less than 1ms. Designed to be used for database
acceleration, and very
demanding throughput applications.
DNAS
DNAS is
a new type storage technology designed for dynamic networking
environments. DNAS delivers significant benefits over traditional
server attached storage.
Plug and
Play Storage
All DNAS
systems come equipped with a direct connection module, which allows
them to connect to your existing network, by just plugging them into
your network hub. All DNAS units come pre-formatted and RAID 5
configured, thus installation is very simple in fact a typical DNAS
unit can be set up and running in less than 15 minutes. There is no
need for client licenses or servers.
Universal
Accessibility
Virtually
any type of client can connect to a DNAS unit, including PC, MAC,
SUN, HP IBM,AS400, in fact, any computer you can connect to your
network can access a DNAS storage partition. A DNAS storage
partition is the area on the the DNAS unit which is reserved for
user data.
Enterprise
Storage Management via a Web Browser console
The
storage partition, is created and managed via a web browser based
management console. The management console is a powerful program
which allows you to administer the DNAS system, and incorporates
such functions, as allocating storage resources amongst users and
setting up a security regime to restrict access based on group or
user id. The management console manages all the DNAS units
connected to your network. This is a very powerful way to manage the
whole of your companies storage resources from one management
console.
Direct
Tape Backup
DNAS
comes equipped with an integral tape backup option. The system
features an external SCSI port, which can be used to connect an
external tape device. The tape devices are controlled by an inbuilt
tape backup program which is administered via a web browser.
RAID 5
Data Protection
All DNAS
units feature RAID 5 data protection. In addition a hot online spare
drive is provided. The system constantly monitors the status of all
drives, if it detects a drive failure, the hot online spare is
automatically activated and takes the place of the spare drive. When
the faulty drive is replaced the new drive then becomes the online
spare.
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.
Infinite
Scalability
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.
Infinite
Scalability
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.
