EMC Muffs Migration

EMC Corp. (NYSE: EMC) has deeply annoyed one of its major customers by not disclosing an incompatibility between the older Symmetrix 3000 series and its recently launched DMX storage arrays.

Last month, EMC launched the Symmetrix DMX, a major enhancement to its flagship enterprise storage lineup. It's pushing these boxes hard, expecting the new systems to account for around half of all its high-end Symmetrix storage revenues for the current quarter (see EMC Soups Up Symm, Does EMC's DMX Measure Up?, and EMC's DMX a Slow Starter?).

But at least one Fortune 100 company -- which is eager to move to the DMX platform -- has been stymied because EMC's data-replication utility on the DMX isn't compatible with the one running on the older Symmetrix model the company already has.

Here's the issue, according to one of the company's storage administrators contacted by Byte and Switch, who insisted that he and his company remain unnamed. This admin says his company was in the process of moving from a three-bay Symmetrix 3930, which had maxed out its capacity at 256 drives and around 10 TBytes.

The company had already submitted a purchase order on a DMX 2000, which was attractive because it offers almost four times the usable capacity (up to 36.8 TBytes) than the 3930. But late in the process, the administrator says, EMC informed him that there's no way to connect the 3930 with the DMX via Symmetrix Remote Data Facility (SRDF), the data-replication software for Symmetrix.
