A MSL5030 tape library with HP OpenView DataProtector software provides automated backup capability. All components are connected via a local Gigabit network. Image post-processing is performed on two dedicated diagnostic workstations (Siemens Leonardo) and two dual-CPU G5 Macs.
All computers are currently networked via Ethernet to the Internet. In addition to the MIPortal system, the computer network contains the following equipment: SGI Silicon Graphics Octane workstation, over 80 Macintosh computers and over 70 PCs.

The area is equipped with a cage/rack washing facility and autoclave. Two 250 sq. ft. limited access animal rooms and attached procedure room for the exclusive housing of immunocompromised rodents located within the 8th floor Central Animal Facility, and will be used for housing all mice. The procedure room to be used for studies under this proposal is equipped with a tissue culture hood, centrifuge, CO2 incubator, refrigerator, microscope and bench space. Animal care in these spaces is under the direction of the Director, Office of Laboratory Animal Resources, and ACLAM certified veterinarian.
