Core Services
Core services cover all application and network support that our community commonly uses. These include, but are not limited to, email, web, file, SQL database and application support. Each of these services is generally housed on its own machine running Windows Server 2003 patched to the latest level. Most of these services are hosted on Dell 1855 blade servers with dual Intel Xeon CPUs and 4 gigabytes of RAM. Many of these servers are also connected to the University’s Storage Area Network (SAN) to provide the maximum flexibility for disk storage. Currently, the University has 4.5 terabytes of raw disk storage available.
Email services are hosted on 2 HP Proliant DL380G5 servers. One machine serves as the email gateway and provides virus and SPAM email scanning. This machine has 1 dual core Intel Xeon CPU and 2 gigabytes of RAM. The other provides internal email services via Microsoft Exchange. This machine has 2 dual core Intel Xeon CPUs with 8 gigabytes of RAM.
