Research Core Services
The Lerner Research Institute's Core Services seek to facilitate and advance research throughout Cleveland Clinic by providing technologies that support basic, translational, and clinical research.
LRI Computing Services
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, and application and print servers. It maintains domain name services for the /17 RFC 1918 IP allocation assigned to the Lerner Research Institute by the Cleveland Clinic Information Technology Division 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 Windows Server team specializes in supporting the Windows Server environment, including domain controller, file, and print, and application services, and Windows and Unix backup. In cooperation with Unix and Desktop support, the Windows Server Team 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 administration team.
Online disk storage exceeds 15 terabytes, which is fully replicated in hardware. A quad-head 670-cartridge LTO-2 tape robot and a quad-head 120-cartridge LTO-2 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, a quad processor Sun 420R with 4 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.
Basic network service to desktop computers is 100 Mbps Ethernet, with 1 Gbps Ethernet available where needed. The Cisco-based network has a redundant 20 Gbps portchannel backbone. Distribution switches link to the backbone via redundant 2 Gbps portchannel connections, or in some cases redundant 1 Gbps connections. Uplinks to the Cleveland Clinic Core are via redundant 2 Gbs portchannel connections. Internet service is provided via the Cleveland Clinic 150 Mbs link.
