COLDSTORE 3U is a unique
sequential surveillance storage
array designed from the ground
up for surveillance
COLDSTORE 3U is ideal for projects requiring affordable high
storage capacity, extended disk lifetimes, long file-retention and
simple system management.

Reliability assured
Our Linear Array of Idle Disks (L.A.I.D™)
technology combined with unique
Sequential disk Filing System (S.F.S™)
produces a powerfully simple system
which can provide generous storage
capacity at low cost. Whilst simple in
concept, this delivers a highly reliable
storage system which dramatically
extends disk lifetime even when using
the lowest cost disks available.
Low power, low cost
COLDSTORE 3U uses only one tenth
of the power of comparable systems,
is resilient to disk failure, requires no
disk rebuild process and reduces
running costs.
It provides an easy way to instantly
extract and transport critical evidential
video data.
Extended Disk Lifetimes
Disks are used sequentially, with all of
the disks not in use being switched
off, saving power and thus greatly
reducing temperature, vibration and
wear – the three primary disk killers.
The system uses a unique mirrored
overlapping-pair writing pattern to
provide full data redundancy during
the critical writing process. This
delivers the redundancy of RAID1
on write, but unlike RAID1, does not
require double the number of disks.
Within the disk, the sequential disk
filing system eliminates vibration from
the read/write head and lowers the
operating temperature. Within the array,
the use of sequential overlapping
mirrored writing pairs requires only
two active disks at any one time
DATA
with the others switched off. This
greatly reduces wear and further
reduces array vibration and operating
temperature. Thus every disk is off, on
average, for 87% of the time. Disks
automatically switch on for playback,
but typically playback from non-writing
disks is infrequent and hardly affects
the average duty cycle.
Purpose-Designed System
COLDSTORE 3U is built around a
custom designed main-board system
with low-power CPU and directly
connected SATA backplane.
Even a fully populated 210TB array
will only use 60 watts. The low power
system extends the electronic component
lifetime, which, combined with the
extended disk lifetimes results in a
very low overall total cost of ownership.

Wisenet WAVE NVRs record to external COLDSTOREs. Multiple NVRs can write to a single
COLDSTORE. A single NVR can be configured to write to two or more COLDSTOREs
(for long retention time applications) with automatic load-balancing. A software plug-in
for the Wisenet WAVE servers enables full COLDSTORE compatibilty.
