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

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.

SWITCH

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.
