nec hydrastor

Corporation NEC, as source reports, is assembled in the near half year to complete revolution in the region of storing data : we deal here with the development of distributed system, which possesses best best safety data even in case of failures or failures of separate units.
Platform NEC was called Hydrastor - obviously, from the word hydra, which designates essence, which quietly survives the loss of part of its extremities. The source, which is referred to the official representatives of Japanese company, asserts that NEC has already been located on the stage of testing .

Hydrastor works under the administration of software dynamicStor, which makes possible to build cluster from the standard servers on x86- compatible processors. However, user will see not separate servers units, but one large accumulator.

But as the answer to logical question and how new system is principally differed from RAID?, the representative NEC gave three arguments:

Control system is differed from control of disk massif RAID. In particular, the possibility of connection or turning off individual servers from the system for preventive or repair work without the cessation of applications working with them is provided. For this dynamicStor starts (in the background regime) the processes of data transfer from servers, who are prepared for turning off, to the working or newly connected systems. On the completion of these processes servers it is possible to disconnect from system.

Minimization of redundancy data, that are stored in the corporate centers storage. For example, if user changed altogether only one slide in the presentation Of powerPoint, which it repeatedly sent out to its associates, then in the system remains both the old and new version of file. DynamicStor, according to its creators, tracks changes in such files and preserves only updated data.
Improved vitality of system: DynamicStor reserves 25% of disk space, which makes possible to survive failure to three servers simultaneously. As the comparison with RAID the source cites these data: 20% of reserved disk space make possible for RAID- system to survive painlessly the failure of one entering its composition disk.

According to the preliminary estimations, the cost of distributed system storage data will be about 1 dollars for giga-byte. Source reports that to Hydrastor appeared interest in the federal backup system OF USA. This, and also good recommendations IDC, it can serve as not bad advertisement for new system, and also for corporation as a whole : NEC survives sufficiently complex times and in the past month it was excluded from the list of firms, on which is comprised market index NASDAQ.
