Overview
The Lerner Research Institute Computing Services group provides support for the desktop, server, and network-computing infrastructure of the Institute. The combined supported user base is greater than 1,000. Platforms supported include Windows 9x/NT/2000/XP, Windows Server 2000 and 2003, Macintosh OS 7 to 9 and Macintosh OS X, and the Unix variants SGI Irix, Sun Solaris, and Linux. The group provides support for shared network disk space and backup, various Internet communication and collaboration protocols, remote access, and application and print servers. It maintains domain name services for the /19 CIDR IP allocation (32 subnets) assigned to the Lerner Research Institute and administers the lerner.ad.cchs.net subdomain of Cleveland Clinic’s Active Directory forest. The Desktop group provides custom support of the scientific computing workstations across the Macintosh and Windows platforms. The Integration/Network Services team specializes in supporting the Windows Server environment, including domain controller, file, and print services, and Windows and Unix backup. In cooperation with Unix and Desktop support, Integration/Network Services works to provide a collaborative cross-platform computing environment. Unix workstations and servers currently participate in a unified computing structure supported by a dedicated Unix administrator. Online disk storage exceeds 17 terabytes, which is fully replicated in hardware. A dual-head 670-cartridge LTO-2 tape robot, a quad-head 120-cartridge LTO-2 tape library and a dual-head 30-cartridge LTO tape library provide backup services. Shared advanced computing resources include a quad-processor SGI 3400 with 4 gigabytes of memory, a quad-processor SGI Origin 200 with 4 gigabytes of memory, a dual processor SGI Origin 200 with 2 gigabytes of memory, and a 14 node Linux cluster. Other Windows, Linux, SGI, and Solaris server resources are available for special hardware or software needs. The infrastructure that provides connectivity for Lerner Research Institute computing is a high-speed, redundant meshed fiber and copper network running on an OC48 (2.4 Gbs) single-mode fiber backbone. Service to the desktop is 155 Mbs ATM (copper or fiber), 100/10 Mbs ethernet (copper), or 622 Mbs ATM (fiber). LAN services (TCP/IP, IPX, Appletalk) are provided via ATM LAN emulation (LANE). After June 30, 2006, a Cisco Ethernet network is slated to replace the ATM network. The backbone speed will be 10 Gbs; basic service to desktop computers will be 100 Mbs Ethernet, with gigabit Ethernet available where needed.
