Adaptec today announced the recall, saying that errors were discovered in QLogic's 12160A SCSI devices, which were used in DPT SmartRAID Decade VI Ultra160 SCSI controller shipped prior to May. The recall affects up to 2,500 RAID controllers, according to Adaptec, which acquired the DPT product line late last year when it bought privately-held Distributed Processing Technology (DPT) in Maitland, Fla. (see Nov. 1 story). The flawed SCSI chips could send incorrect information to the RAID system controller, which then can hang up the bus or cause parity errors, according to Bob Schultz, chief operating officer at Adaptec in Milpitas. "Adaptec has a zero tolerance policy for components that compromise data protection," Schultz said. He added that because the defects are difficult to detect in the QLogic chips, the company has decided to recall all of the potentially affected components as a precaution. During a conference call with financial analysts today, QLogic officials in Aliso Viejo, Calif., said Adaptec's problems resulted from the company being too aggressive in shipping RAID controller products with pre-production ICs than were still being tested prior to release as volume products. Other system makers do not have the same problem, since they decided not to ship products with the pre-production SCSI devices, said H.K. Desai, chairman, CEO and president of QLogic. The QLogic CEO added that the problem and Adaptec's recall will have no financial impact on his company, which today reported record revenues of $68.3 million in the fiscal quarter, ended July 2., and a net income of $21.1 million. Adaptec's Schultz said problems in the QLogic chips were discovered during advanced testing of compatibility in the DPT RAID controllers. Serial numbers for the recalled products are 03-000001 through 03-005599 (located at the bottom right hand corner on the face of the RAID controllers). Adaptec said it was providing a replacement RAID product as well as up to $300 for installation expenses. semibiznews.com
