![]() This way, dead ends would be preserved and previous generations of hardware, circuit boards and software could be identified. ![]() Previously, nothing was thrown away, but moved into hierarchs of "Canon" and "Apocrypha" according to the last revision signed off. I asked if they looked at the ToO doc I wrote and I was told that the documentation system had been "streamlined" to get rid of deadwood and it was quite likely that all of my descriptions were tossed by my replacement who didn't like me with a passion for some reason never specified. Years after I left, I talked with another engineer that had also left and told me I had been cursed due to somebody that couldn't get their head around a multi-input redundant power supply I had designed and built. I felt that if everybody had to figure out things from first principle analysis, they wouldn't be there long enough to sort out what they needed to know to be productive. ![]() The company was growing and at the same time had lots of turn over due to lack of adult supervision. A lot of things we did were "one-off" and very unique. I got told off for writing them at an aerospace company, but as the head of the department, I felt they were needed for a better understanding of what the engineer was trying to accomplish and the problems they were trying to solve. The long lost "theory of operation" statements have need of a comeback. "however somewhere in the 20 years since the campus was built the message was lost" It took a long weekend where everything was turned off, then brought back on in a controlled order before things worked again. If systems were built that redundant pairs were in alternate racks then the failure of a single generator should be manageable - however somewhere in the 20 years since the campus was built the message was lost - many systems turned out to have redundant capacity fed by a single generator, and one such system was the AD farm.The grid power was quickly restored but systems had already failed by that point. When the campus was originally designed it was decided to "stripe" power from the generators - every other desk, every other rack in the DC etc. Except one day one of the generators didn't kick in. Once a month - as a test - grid power was turned off and the backup generators kicked in, then they were failed back. They had a pair of very large diesel generators in a different building - which provided backup power to the entire campus. Many years ago I worked for an organization that ran its own data centers. No fire damage was inflicted on customer servers.Re: This would never have happened at a certain broadcaster I used to work for. Those builds have a high probability that data is intact.' They added: 'Customer's servers in one of our main bays were exposed to water and possible damage may have occurred. 'Some servers will have an extended outage as they may require rebuilds due to some water damage. 'However, during that transition, one of our backup generators that had been recently tested and benchmarked specifically for this situation experienced a catastrophic failure, caught fire, and as a result initiated the fire suppression protocol.' 'Sunday afternoon the city power was disrupted and, as designed, our backup generators automatically switched on,' the company said in a Facebook post. He also confirmed that some of Ogden City's IT services were down on Sunday and Monday as a result of the data center fire. He said power was cut to the building until an electrical engineer could inspect the facility to make sure current could be restored safely, which he added is standard procedure. The fire, he said, 'originated in a generator in the building and spread to several servers.' Brown said the facility's fire suppression system contained the blaze and that fire department personnel assisted with the cleanup. ![]() Kevin Brown, Fire Marshal for the US city's Fire Department told The Register in a phone interview that firefighters responded to a call on Sunday evening. Joe_Dragon shares a report from The Register: A power outage kicked off a fire in web hosting biz WebNX's Ogden data center in Utah on Sunday, knocking the facility offline temporarily and leaving several servers in need of a rebuild. ![]()
