An urgent service outage is needed today to address performance issues with several campus systems such as Active Directory (AD), Blackboard and Financial Systems. Specifically, these services operate on what is known as “virtual” servers or dedicated “zones” on a small number of physical servers. Over the past four weeks the primary storage arrays for our virtual servers have been experiencing performance issues resulting in occasional failures of various systems. Many of these outages have occurred during the weekend hours when they were less noticeable. Our storage vendor has recommended upgrading these systems immediately to resolve these issues. The services listed below will be offline Friday, October 29, 2010 between 10 p.m. and 3 a.m. while an updated storage firmware patch is applied.
