 Storage in the EnterpriseThis newsletter is sponsored by Silver PeakNetwork World's Storage in the Enterprise Newsletter, 05/22/07Hitachi releases speedy, bigger arrayBy Deni ConnorHitachi Data Systems last week set out to prove that bigger and faster is better with the launch of a refreshed storage system. The Universal Storage Platform (USP) V offers 3.5 million I/Os per second of performance and scales to as much as 247PB of data capacity. The USP V has a 4Gbps Fibre Channel switch backplane, which provides customers with immediate access and storage of their business-critical data. Like its predecessor, the USP V allows the virtualization of external heterogeneous storage. A new feature, Dynamic Provisioning allows storage utilization to exceed 85%.
The internal virtualization of the USP V includes thin provisioning, logical storage pools, wide striping, virtual partitions and QoS. Its external virtualization allows management of heterogeneous storage systems. The USP V is 520% faster in writes to disk and 210% faster than its predecessor. The company also improved the performance of its Hitachi Universal Replicator by 130% and its TrueCopy Synchronous link performance by 200%. The crossbar switch architecture now features full 4Gbps Fibre Channel connectivity from front-end director level switches to back-end disks. Further, the USP V is capable of 320 concurrent internal memory operations, a figure Hitachi claims is 900% faster than ultra large scale storage systems from EMC and IBM. The control memory of the USP V has doubled from 16GB to 32GB and the dedicated control paths increased 33% to 256. Dedicated control bandwidth has increased by 138% to 38Gbps and total internal bandwidth has increased by 31% to 106Gbps, which according to Hitachi’s claims, is a 560% increase over systems from EMC and IBM. Finally, the USP V offers 224 front-end 4Gbps Fibre Channel ports for connection to host computers. It supports 112 4Gbps FICON ports and 112 ESCON ports.
