The United States IBM high performance computing (HPC) to receives the fact that interest has increased between the enterprise user, has tackled strengthening the high performance file system.
IBM strengthened file management performance "General Parallel File System (GPFS)" new version is the schedule which release is done on October 5th. Marketing of the IBM power systems/strategic charge vise President, the Scot handy person has explained besides the fact that the search which strided the plural systems concerning the new version of GPFS, is possible, when it can process in parallel to the maximum of 1,000 nodes.
NSD (Network Shared Disk) the constitution example of GPFS due to connection
The handy person emphasized that it succeeds in the file scan of 10 hundred million cases with the test which used GPFS, appealed the functional predominance to the customer of banking facilities and retail which handle the mass non structuring file field. According to the same person, with the test it completed scan at about 2 hour half, but as for IBM, you say that the match which furthermore shortens this to 1 hour is being advanced.
GPFS (presently version 3.2), policy based file management function can be loaded in update edition, the user can indicate the preservation method and search method of the file vis-a-vis the system. If this function is used, the file which is retained with the format of specification and the like it becomes possible to retain in the disk of type of specification.
The handy person has explained when it is possible to decide the distribution method of the data, with the approach of ranking. For example, it draws up policy on side of the user, most at high speed retains the data of type of specification in the expensive disk, as retained low in the system of the cost where performance is not seriously considered, it calls the data other than that that it can set.
If this function is utilized, low it is possible according to the type of data which is retained is connected to cost avoidance savings to utilize the storage of cost efficiently.
In addition, in the policy based system, for example, also it becomes possible 30 days by the fact that the fixed time limit which was said is set, at that time to make the file which does not have access the system of cost move completely low. According to the same person, with the old version of GPFS, as for such processing you say that it was not possible. IBM in addition, has tackled also cluster management functional addition.
It works GPFS, in System p of IBM, and the System x series other than AIX, supports the part version of Red Hat and SUSE Linux.
