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 2U is a low cost option with the same unique COLDSTORE sequential video storage technologyCOLDSTORE 2U is ideal for smaller 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 uniqueSequential 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 costCOLDSTORE 2U is designed to provide all the key features and reliability of COLDSTORE technology at a lower cost and in a smaller rackmount format. It is aimed at small to medium-sized projects with camera counts up to 100 channels with typical bit-rates. With a Gigabit Ethernet port, the system can handle up to 600Mbps of video traffic, depending upon integration. 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.
