The Structural Biology computer network consists of over 360 computer systems throughout the department for individual, shared, and instrument use. Computers are connected via gigabit Ethernet and run Linux, Mac OS X, or Windows. Authentication to computers, storage, and other network resources is provided via a centralized LDAP directory.
Storage is provided using a flexible and dynamically tiered Storage Area Network (SAN) architecture. The SAN passes data over an independent and redundant 10-gigabit-ethernet backplane using jumbo frames and the iSCSI protocol. The SAN combined with direct-attached storage resources currently provide over 260 Terabytes of capacity to network users.
Backups and archiving are administered via an expandable LTO-5 robotic tape library system. Intermediate disk staging of backup sets is used to minimize tape wear and network traffic. Our magnetic data backup and archiving capacity is in excess of 700 Terabytes.
We have two computer labs consisting of 19 workstation-class Linux computers with access to many data processing and structure analysis programs for NMR spectroscopy, CryoEM, and X-ray crystallography. Scientific software environments and versioning are managed with environment modules. These computers and software are available to all of the faculty and students in our department.
