Hitachi Data Systems (HDS) has announced major upgrades to its two highest-end storage arrays, including software that allows the systems to mimic optical discs' Worm (write once, read many) capability.
The HDS Thunder 9580V is a high-end modular storage system that can be used to consolidate smaller modular storage systems or older JBOD systems. It can also be used in a tiered storage infrastructure with HDS's monolithic Lightning 9900V array.
HDS's 9580V doubles capacity from 32TBytes on the old model to 64TBytes of San network attached storage or direct attached storage configurations.
HDS has also increased the number of fibre channel ports from four to eight, running at 2Gbit/sec throughput. The array will offer up to 1,024 virtual storage ports with a technology similar to that used to create virtual private networks.
HDS also doubled the cache in its high-end monolithic array, the Lightning 9900V, from 64GBytes to 128GBytes, and increased the number of Escon ports from 36 to 48.
The Worm feature added to HDS's Lightning 9900V array is a move designed to help financial services firms comply with the electronic records storage requirements of the US Securities and Exchange Commission, whcih requires firms to store electronic documents in an unchangeable format such as optical disc.
John McArthur, an analyst at IDC said HDS's Worm capability will compete against EMC's Centera array, which was introduced in April 2002.
