DSI's
Solid State Disk products provide the easiest and
fastest way of removing I/O bottlenecks and increasing
system performance. Utilizing a DRAM architecture
for storage rather than traditional magnetic disks,
these high-performance solid state disk devices are
capable of delivering data of up to 3 GB/s! With
no latencies associated with head positioning or
seek times, the resulting read/write operations are
hundreds of times faster than conventional rotating
disks.

DSI's current line of Solid
State Disk products includes the DSI1200, DSI3250,
and the DSI3250E. With no changes
to the existing operating system or processor hardware,
installation
is easy and usually performed in less than one hour!

Accelerating the Application
Computer
systems and networks have increased exponentially
in both speed and performance throughout the 'Digital
Age'. Conversely, storage device speed— measured
by seek time, operations per second, total bandwidth,
and other mechanics—have remained relatively stagnant.
These storage device limitations have created
a significant bottleneck, resulting in a substantial
performance gap over the years. In high-demand
networks, this performance gap is painfully obvious—the
fastest processors in the world are underutilized
if the storage device can't carry out its orders
fast enough. And in situations where “hot-files”
and databases are constantly read from or written
to by multiple sources across a network, this
bottleneck creates a crisis for the entire network
infrastructure.
Bringing storage devices into the 'Digital Age',
solid state disk technology removes the I/O bottleneck
by replacing hard disk drives with high speed
circuitry. Instead of a rotating disk, a solid
state disk uses memory chips (typically SDRAM)
to read and write data, resulting in full utilization
of existing processors and bandwidth. With an
access time of only 20 microseconds, SDRAM delivers
data 250 times faster than conventional disk
drives. Uncompromised SDRAM data integrity
is maintained through both battery backup and
redundant disk drives, so your data is always
protected on solid state disk. |

| The
3250E doubles the capacity of the
popular DSI 3250. The primary
storage media is the DDR
(Double Data Rate Memory), with four
independent disk drives providing secondary
storage as well as optional data mirroring
(active backup). Writes are performed
to all four media while read operations
are performed by the DDR (active backup
option), thus solving the DDR volatility
issue—three disk drives each have
an updated copy of all data sets even
when the 3250 powers off. Two redundant
and hot swappable power supplies, fans
and multiple drives allow the 3250
to survive multiple points of failure
while maintaining data integrity. Additionally,
3 internal batteries are used in the
event of a power failure. Utilizing
3 GB/s bandwidth at 250,000
I/Os per second, the 3250 gives
you the best of both worlds; fast data
access and high data reliability. |
