Compact IP video surveillance storage system

COLDSTORE Compact 8-Bay, 2.5" Storage System

Compact, low power, high-reliability, sequential video surveillance storage system

COLDSTORE COMPACT is a Networked Server designed specifically for IP video surveillance systems which need a compact storage system for mega-pixel IP cameras. Designed from the ground up specifically for surveillance, this very compact sequential storage system maintains the veracity of your data in an uncompromisingly secure way with the following unique features :

• 40TB capacity using only 16watts – massive power saving versus RAID

• Very high disk reliability even using the lowest cost disk drives available

• No data loss on disk failure, with no rebuild required, and simple disk hot-swap for evidence seizure

• Sequential filing system (SFS™) unique

• Uses 8 x 2.5 inch drives - a 5TB drive fits in your pocket

Whilst simple in concept and in use, the technology incorporated within COLDSTORE COMPACT delivers a very high reliability system even when using the lowest costs disks available.  Our Linear Array of Idle Disks (LAID™) system combined with our unique Sequential Filing System™ (SFS) produces a powerfully simple system which provides large capacities at very low cost. The compact system is extremely simple to manage, as all disk set up and configuration is entirely automatic.  The end-user can add, remove, replace and even upgrade disks.  These operations are done without ever stopping the recording of data.

Sequential Recording

Disks are used sequentially, with all disks not in use being switched off, saving power and thus dramatically 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, but not requiring twice the number of drives of fully-mirrored RAID1 systems.

Even More Power Efficiency

COLDSTORE COMPACT exploits the fact that only 3% of video data is ever replayed, and so every disk is off (on average) for 87% of the time.  SFS™ controls the disk read/write heads, moving them across the disk very much like a vinyl record player, virtually removing disk vibration.  Combining LAID™ and SFS™ together with a custom-designed low-power main CPU board results in a disk array which hardly needs any cooling at all, and uses as little as 16 watts even with a fully populated 40TB array.

As there are special times when it may be necessary to run all the drives simultaneously for an extended period (e.g. during a mass search process), COLDSTORE COMPACT is designed to handle this with ease, using a 12V DC, 3A external power supply - and almost silent cooling fan.  Even in this mode, COLDSTORE COMPACT will use around only 25 watts maximum - far more efficient than typical RAID systems.

Disk Types and Physical Location of Data

COLDSTORE COMPACT can use a mix different capacity's of 2.5" SATA disks.  Disks may be added "on the fly" and will automatically be incorporated into in the array.  Disks may also be extracted at any time, and due to the strictly sequential writing pattern, physical location (and extraction) of any particular recording for evidential purposes is simple, this powerful feature allows the disks in the array to be easily managed by the end users themselves.

Operating Modes

In addition to the mirrored overlapping-pair mode, COLDSTORE COMPACT can also operate in single sequential disk mode and sequential mirrored-pair mode (i.e. sequential RAID1) as required.  These modes of operation still benefit from the power-saving, low temperature, vibration and wear features of LAID and SFS, including simple disk management and instantaneous extraction of evidence.

Integration with Video Recording and Management Systems

Veracity provides a simple SDK to DVR/NVR manufacturers who wish to provide their end users with the benefits of COLDSTORE COMPACT.  Direct control of COLDSTORE via a defined network protocol is an alternative method of integration.  COLDSTORE COMPACT is delivered with a full configuration and management application.  Once configured, disks may be removed and extracted at any time without re-configuration.  LEDs on the exterior front panel show the drive status.
