IT Core Infrastructure

When is this service available

The IT Core Infrastructure systems are normally available 24/7.  If a planned outage must occur, it will be announced on LibNews-L and typically scheduled during our Scheduled Maintenance Period (05:00 - 09:00 Sundays, excepting finals weeks).

Priority level for this service

Maintaining the normal operations of the IT Core Infrastructure systems is the #1 critical priority for Library IT Infrastructure & Software Development Unit. We and the system vendors make every effort to resolve problems with this service as quickly as possible, including evenings and weekends.  We have automated systems to monitor and alert ISD staff if systems fail.  Also, the Compellent SAN is proactively monitored by the vendor 24x7 under support contract, and VMware is under a 24x7 support contract.

How to report a problem

Any significant problem with the Core Infrastructure will cause multiple user-accessible systems/services to be downgraded or unavailable, and those services each have their own distinct Service Commitments.  It is unlikely that Library staff would be able to directly detect a Core Infrastructure outage, but if multiple systems dependent on it fail together, it is a likely cause.

During business hours (8:30AM-5:00PM M-F) please log a ticket with the IT Help Desk or call the Help Desk at 244-4688.  If no answer, try ISD directly at 244-6300.

Outside normal business hours, please call ISD directly at 244-6300 and contact the Grainger Library at 333-3576.  Grainger staff can notify appropriate Library IT personnel.

Description

The Core Infrastructure is actually an aggregation of several systems upon which most of our user-accessible systems and services depend.  From a layman's high level perspective, the Core systems can be considered a single large service because in most cases, we provision virtual servers along with their virtual data storage from within the Core -- currently over 20 of our servers are virtual machines operating that way.  Individual IT services then run on one or more of these virtual servers.  Our virtual servers each run either Windows 2003 Server or Red Hat Enterprise Linux.  Additional information is on ISD's web site.
