The world's most reliable surveillance storage system with increased throughput and performance

COLDSTORE's sequential recording system SFS™ writes to hard disk in a revolutionary way and offers extreme reliability with low total cost of ownership.

COLDSTORE 3U Pro is a unique sequential surveillance storage array designed from the ground up for video surveillance

COLDSTORE 3U Pro 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 COLDSTORE's 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 if using the lowest cost disks available.

Low Power, Low Cost
This 3U Pro version of COLDSTORE provides higher performance over the standard 3U system but with the same high levels of reliability. It is aimed at the more demanding applications of high camera count and higher bit rates. With dual Gigabit Ethernet ports which can be bonded, the system can handle up to 1Gbps of video traffic.

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 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 Pro is built around an industry standard main-board system with a power-efficient CPU and Veracity designed backplanes.

Even a fully populated 300TB array will use less than 60 watts. This low power consumption extends the electronic component lifetime, which, combined with extended disk lifetimes, reduced cooling costs and lower UPS purchase cost, results in a very low overall total cost of ownership.
