Does EMC's DMX Measure Up?: Page 3 of 5

"EMC claimed that the Symmetrix DMX non-blocking architecture 'delivered the world's highest performance,' yet it has failed to disclose any industry-standard benchmark results, such as those available from the Storage Performance Council, that would back this claim up," says David Scott, CEO of 3PARdata Inc., a startup that has developed a high-end utility storage array competitive with the Symmetrix and HDS Lightning (see 3PAR Claims Benchmark Title).

EMC's position is that the SPC-1 benchmark is meaningless, because it doesn't test "real-world performance." That said, EMC is the only major vendor that is not participating in the SPC. "Until EMC shows what the box can actually do on the SPC benchmark, there isn't any fair comparison that can be made," says IBM Corp. (NYSE: IBM) spokeswoman Sandra Dressel (see LSI Screams Past IBM, Sun and HP Fiddles With Cache).

Meanest: In terms of pricing, the DMX simply drops the Symm in line with the rest of the industry. The DMX 800 starts at a list price of $409,000, cutting the entry-level price point for the Symm by about a third. EMC says its entire family of storage is priced at between 4 cents and 8 cents per MByte.

This is clearly a good development for customers, and it makes the DMX all the more attractive to prospective buyers. But it also reveals that EMC recognizes the tables have turned -- and that it's unable to charge a significant premium over its competitors.

Biggest: Nope. At least, not yet. The DMX, in fact, drops the maximum number of disk spindles it can support from 384 in the Symmetrix 8000 to 288 in the DMX 2000. However, EMC notes that with parity RAID turned on, the DMX has greater usable capacity -- 36.8 TBytes -- than the Symm 8830, which offered 34 TBytes of usable capacity with mirroring turned on.
