Engineers Take LeftHand Turn: Page 2 of 3

To keep up with the mountain of files it produces, WJE looked at NAS solutions from Snap Appliance Inc. and Maxtor Corp. (NYSE: MXO) but concluded these systems weren't stable enough to cope with its load. It contacted a local value-added reseller in Illinois for some advice and received a laundry list of options, including Fibre Channel-based SAN storage, direct-attached storage (DAS), and IP storage.

Each option would have solved WJE's problem, but the question was which to go with.

The firm considered Adaptec Inc.'s (Nasdaq: ADPT) DuraStor DAS solution, which had an attractive price but did not allow much expandability. "It is limited as to the number of servers that can use it," Jaskot says.

Meanwhile, Jaskot liked the Hewlett-Packard Co. (NYSE: HPQ) Modular SAN Array 1000 (MSA1000) but says the Fibre Channel switches used to support it were too expensive. Moreover, he says, "Fibre Channel seems to be a stagnant technology. The upgrade path isn't clear."

He'd done some research into IP SANs but was unsure about the reliability of the technology -- until he watched a demo from LeftHand Networks.
