The Thunder 9580V will double the cache available -- to 8 Gbytes -- and will also double the front-end connectivity of the system to a maximum of 8 Fibre Channel ports compared with the 9570V, which is currently the highest-end member of the Thunder line, according to sources familiar with the product.
The new model will be the latest refresh of the Thunder 9500V line, which HDS launched in December 2002 (see HDS Tries to Steal EMC's Thunder). These systems compete with the EMC Corp. (NYSE: EMC) Clariion CX, Hewlett-Packard Co. (NYSE: HPQ) Enterprise Virtual Array (EVA), and IBM Corp. (NYSE: IBM) FastT arrays, among others.
HDS representatives did not respond to repeated requests for information. [Ed. note: Obviously, they were too busy stuffing additional cache into the new Thunder boxes.]
However, HDS will apparently still lag the field in terms of software functionality. For example, the Thunder still lacks snapshotting -- the systems require users to make full copies of replicated data.
