HP releases 10-petabyte D2D system
Last year, HP released the first D2D disk backup systems based on the HP Labs deduplication technology developed by the scientists with selective indexing of the StoreOnce .
Recall that the main highlight of StoreOnce's selective indexing is the accelerated processing of backups due to the more efficient organization of duplicate search in the backup device index.
At the next all-European forum of HP customers and partners, which this year took place in the Austrian capital at the end of November, the company showed a new enterprise-class D2D backup system, which also uses StoreOnce deduplication. The HP B6200 system scales from 48 to 768 TB of physical capacity (384 two-byte full-size SAS disks) or 512 TB of usable capacity and provides backup speeds of up to 28 TB / hour, which allows a standard eight-hour backup window to store 224 TB of data. If we take into account that StoreOnce can reduce the size of backups up to 20 times, then the maximum amount of backups that can be stored on this system is ten petabytes! The HP B6200 is equipped with 4-16 ten-gigabit Ethernet ports and the same amount of eight-gigabit Fiber Channel.

Since this system is designed for large corporations (it is able to accumulate data from 384 network systems), to increase the reliability of backup, its controllers are integrated into a failover cluster and redundancy of all major hardware components and links is used, i.e. there is no single point of failure. Most backup devices offered by other vendors today lack such means of protection against failures. The basic system consists of two controllers and two disk shelves. When upgrading, both controllers (up to 8 pcs.) And disk shelves (up to 32 pcs.) Are added, which allows increasing not only capacity, but also system performance.
HP Labs continues to improve StoreOnnce and the HP B6200 implements a new deduplication feature, Sliding Window Assigne, to speed up data recovery from its backup copy using containers of different sizes and multi-threading mechanisms. HP is also going to integrate StoreOnce-based deduplication into the next version of the HP Data Protector backup software package.
