Sun Fire Server

Sun Microsystems Sun Fire 12000 ServerThe Sun Fire 12K server is a high-end data center server that lets customers reduce acquisition and ongoing operating costs through more precise hardware selection. Supporting up to 52 UltraSPARC® III Cu 1.2-GHz processors and 288 GB of memory per domain. An ideal platform for server consolidation, mainframe rehosting, high-end technical computing, and data-intensive applications, the Sun Fire 12K server enables customers to deliver large-scale, mission-critical services at lower costs than competing solutions. To support future growth, the Sun Fire 12K server also provides a smooth upgrade path to the Sun Fire 15K server without disrupting service.

Biostatistical Support:The Biostatistics Section in the Department of Public Health Sciences offers expertise and support in many biostatistical areas, including: Bayesian analysis, categorical data analysis, causal inference, clinical trial design, empirical Bayes methods, epidemiological statistics, health services research, hierarchical models, imaging and pattern recognition methods, incomplete data analysis, Markov Chain models, measurement error models, latent variable models, longitudinal and clustered data analysis, misclassification error, multivariate analysis, nonparametric methods, psychometrics, sampling, statistical computing, statistical genetics, survival analysis, and sequential data analysis Computing Support:

Research computing (RC) for Wake Forest University Health Sciences is provided by the Department of Public Health Sciences (phS) . Computing is supported through an FTE-based monthly fee which pays for the LAN access, network infrastructure, desktop support, CPU use, and disk storage. Core processors which form the computing base for the PHS Computing Facility include

Unix Servers (Sun Solaris)
  • 2-SunFire V880 with 8 900 MHz CPU, 16 GB of RAM, and 430 GB internal storage
  • 1-SunFire F12 with 12 105 0 MHz CPUs, 96 GB of RAM, and 576 GB internal storage
  • 1-Sun E3500 with 6 450 MHz CPU, 3GB of RAM, and 170 GB internal storage
Storage Area Network (SAN)

Each of these UNIX systems is connected via Fibre Channel to a SAN. The SAN is comprised of:

  • 2 Brocade Fibre Channel Switches
  • 1 MTI Storage Array containing 1.5 TB of RAID protected storage
UNIX Workstations (Sun Solaris)

In addition to the core Sun servers, RC also supports an integrated UNIX workstation configuration, configured as follows:

  • 11-SunBlade 150 (user node)
  • 1-SunBlade 2000 (user node)
  • 2-Sun Enterprise 250 (user node)
  • 2-Sun SparcStation Model 20 (user node)
  • 15-Sun SparcStation Model 4/5 (user nodes, web server)
  • 7-Sun UltraSparc Systems (user nodes)
High Performance Compute Cluster (HPCC)

Researchers may also leverage the HPCC system. The HPCC system is a collection of servers running as one. This system is made up of 18 Dell servers (compute nodes) working together under the direction of one head node. The head node utilizes Sun Grid Manager to distribute jobs to the compute nodes thus allowing jobs to be split up and run simultaneously amongst many CPUs. The cluster is made up of the following components

Head Node - 1 Dell 2650 Dual 2.8GHz Xeon processors 2GB RAM and 290GB internal storage

Compute Nodes - 2 Dell 1750 Dual 2.4GHz Xeon processors 8 GB RAM and 36 GB internal storage - 16 Dell 1750 Dual 2.4GHz Xeon processors 4 GB RAM and 36GB internal storage

  • Sun Grid Engine
  • Ganglia system performance monitoring
  • System Imager for node re-creation
  • Gigabit Ethernet interconnect
Additional support equipment
  • Dual Drive SDLT 30-Tape Library
  • 5-4mm DAT cassette tape drives
  • 1-1.7GB Hitachi magneto-optical disk drive
  • 1-9 track reel to reel tape drive (6250, 3200, & 1600 bpi)
  • 1-HP IIIsi Laser printer (Ethernet based)
  • 1-HP IVsi Laser printer (Ethernet based)
  • 2-HP Vsi Laser printer (Ethernet based)
  • 1-Xerox 4920 Color Laser printer
  • 8 Windows NT 4.0 application servers
  • 5 Windows NT 4.0 web servers
Supported Software

PHS utilizes many specialized applications to do perform genomics research. This following list comprises a subset of these applications:

  • Gene Hunter
  • Merlin
  • Solar
  • PedSys
  • loki
  • glogit
  • ghp

Statistical software supported includes SAS, S-Plus, BMDP, Stata, StatXact, IML, and Fortran. Other compilers include C, C++, and Pascal. Editors available include VI, EMACS, Nedit and ed.

Windows NT and Computer Room

The Department supports 300 Windows based workstations. A computer center houses 23 IBM and Dell Servers. These Departmental servers include database servers, web hosting servers, SAS servers, application servers, file servers, web site development servers, and workstation backup servers.

All servers that are available to the Internet, are secured in a DMZ zone, with two hardware firewalls. Local software firewalls are also used on each public server. Public server access is monitored at the hardware firewall location, by an outside monitoring company. The Department also monitors public servers, at the server software location, to help guarantee security. Operating system patches and hotfixes are implemented in a timely fashion, and can be managed remotely in an emergency.

All servers utilize RAID storage configurations for hardware reliability. Servers are backed up to tape, nightly, using our Legato Networker server backup system. The tape backup system has redundant SDLT Quantum drives with an on-line storage capacity of 7.5 Terabytes. The backup system in monitored daily by redundant administrative staff. Backup tapes are stored in a locked, fire-proof, storage vault, located outside the computer center, to ensure optimal disaster recovery. Additionally, a secure, off-site vault is used for tape storage. The computer center is air-conditioned, power conditioned, and monitored. Power conditioning and battery back-up capability is provided by our 7000 KVA BEST FERRUPS uninterruptable power supply, and our 18,000 KVA Powerware UPS.

The computer center is equipped with an automatic notification system to ensure response to unexpected electrical outages, temperature abnormalities, and excessive noise conditions (i.e. fire alarms, smoke detectors, cooling fan noise etc.).

Secure, monitored, VPN access is available to system administrators to allow remote access to computing resources.
