Enhancements to QMUL HEP Facilities: Workstations, Servers, and Future Plans (April 2005)

This report outlines significant upgrades to the QMUL High Energy Physics (HEP) facilities as of April 2005. Key improvements include the addition of Linux and Windows workstations, high availability servers, and an E-Science farm. Renovations also led to an expanded capacity for dual-processor nodes and enhanced storage solutions, bringing total RAID capacity to 40 TB. The report details daily backups, load balancing, and future plans for transitioning to dual 64-bit workstations. Amid these advancements, we bid farewell to Chris Williams, our esteemed SysAdmin.
