You've probably had it happen, and there's nothing quite like it. First thing Monday morning, a "MUST be handled before noon!" list of emergencies hits you in the face: 1. The sales manager is squawking because CRM database is slow 2. Accounting is nagging because email is slow 3. The NAS server is averaging unacceptably high counts of queued disk I/Os 4. You're getting constant poor performance alerts from the SAN 5. Backups have not been completing during the backup window These nagging, ulcer-creating problems are also the subject of several emails from the CFO because, on top of being bad for company production, in this time of economic uncertainty they're also bad for business. Work is being slowed down and the company is losing money.
