Access "Midrange arrays get a makeover"
This article is part of the Vol. 4 No. 4 June 2005 issue of Exploring new options for disk-based backup
What you will learn from this tip: Two fixtures of the midrange modular array scene have received substantial makeovers, and more are on the way. Last month, IBM announced a successor to the DS4500 (formerly FAStT900) -- the new DS4800. Based on an OEM version of Engenio's 6998 controller, the DS4800's newest asset is its 4Gb/sec Fibre Channel (FC) host interface which, according to Engenio, delivers 550,000 IOPS from cache vs. 148,000 IOPS for the previous-generation 5884. Furthermore, the 550,000 IOPS are roughly twice as much as EMC quotes for its Clariion CX700. The DS4800 is scheduled to ship next month.

Another Engenio OEM for this product, Silicon Graphics Inc. (SGI), sells the array as the SGI InfiniteStorage TP9700, and has placed it in support of a 2,048 processor ... Access >>>
