From: [email protected] [mailto:[email protected]] On Behalf Of Gabe Goldberg Sent: Tuesday, 13 May 2014 12:26 p.m. To: z/VM Discussion List; IBM-MAIN automatic digest system; VSE Discussion List; LINUX-390 List Subject: Query for Destination z website -- relocating a data center Have you moved a data center? What was involved? How much "fun" was it? What was involved, from start to finish? Does the old disruption rule, "two moves equals one fire" apply? Please share lessons learned, gotchas suffered or avoided, "if only" wishes, war stories, etc. Here's some thinking points (not necessarily in project order, listed for completeness)... * Was the move worse than an data center build, initial installation, or upgrade? * Planning * Schedule, timeline, milestones * Logistics * DIY move vs. contractors/subcontractors * Site preparation, e.g., check outlet before plugging in anything too stupid to protect against bad circuit. I saw one vendor's (not IBM) equipment burned out when field manager didn't check power. * Achieving non-stop operation or outage tolerable? * Business continuity during execution * Flexibility during execution * Move equipment vs. install all new? * Incremental move or big-bang cutover? * Parallel operation of old/new data centers? * Back-out plan or point-of-no-return? * Transition period? * Testing * Software licensing * Costs * Results, assessment, postmortem, etc. As usual, please copy reply to me so it's not lost in list digest.
