COLDSTORE 3U Pro is a network attached Sequential Array designed specifically for today's video surveillance systems which need very high capacity storage for mega-pixel IP cameras and/or long archive periods. Designed from the ground up for IP video surveillance, this sequential storage system achieves the following unique features.
Simplicity
Whilst simple in concept and in use, the technology incorporated within the COLDSTORE 3U Pro architecture delivers a very high reliability system even when using the lowest costs disks. Linear Array of Idle Disks (LAID™) system combined with unique Sequential Filing System™ (SFS) produces a powerfully simple system which provides massive capacities at very low cost. The system is extremely simple to manage, with all disk set up and configuration being entirely automatic. The end-user can add, remove, replace and even upgrade disks. These operations are done without ever stopping the recording of data. COLDSTORE 3U Pro is extremely simple to manage. No data loss on disk failure, with no rebuild required. Unprecedented reliability - even using low costs disks.
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.
Power Efficiency
COLDSTORE 3U Pro 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 60 watts even with a fully populated 300TB 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 3U Pro is designed to handle this with ease, incorporating a well-specified power supply - dual hot-swappable PSU and temperature-controlled chassis cooling fans. Even in this mode, COLDSTORE 3U Pro will use around 120 watts maximum - more than three times as efficient as typical RAID systems.
Disk Types and Physical Location of Data
COLDSTORE 3U Pro can use any make and size of SATA disk and indeed any mix of 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, the recorded time-span of any disk may be displayed on the front panel. This allows simple physical location (and extraction) of any particular recording for evidential purposes. Such simple, yet powerful features allow 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 3U Pro 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 3U Pro. Direct control of COLDSTORE 3U Pro via a defined network protocol is an alternative method of integration. COLDSTORE 3U Pro is delivered with a full configuration and management application. Once configured, disks may be removed and extracted at any time without re-configuration. Array management may also be done directly via front-panel controls. The front panel is also used to show array status, disk capacities, disk time span and IP address.
