Submission + - 365 Main Generator Flaw May Affect Other Providers (datacenterknowledge.com)
1sockchuck writes: "A flaw in a Detroit Diesel Electronic Controller (DDEC) was the key point of failure in the July 24th power outage at 365 Main's San Francisco data center, the company said today in a report to customers. The controller manages generator speed, and effectively prevented three of the data center's generators from starting properly when grid power from PG&E was interrupted. While much of the media attention has focused on the blame game, the DDEC flaw may affect other data centers using the same component, which has been discontinued but is still in use in many generators. "We've talked with other people in our industry that have seen the same issues," said 365 Main's VP of operations. "This is a problem that is going to be felt by anyone who is using a Detroit Diesel MTU 4 controller." 365 Main's generator vendor, Hitec Power, is said to be contacting other customers with similar equipment to head off a repeat elsewhere."
