SERIS Infrastructure

SERIS is part of the University of Tennessee's SunSITE server park. SERIS production services run on two Sun Fire 280R servers, each with two 900MHz UltraSPARC-III Cu processors, 8MB E-cache, 4GB memory (4 x 1GB DIMMs), two 73GB 10,000rpm HH internal FCAL disk drives and two power supplies.

For pre-deployment testing and staging, we use another identically configured Sun Fire 280R server and a Sun Ultra Enterprise 450 server with dual 400MHz SPARC2 processors.

Our principal mass-storage consists of a 2TB Sun StorEdge 6320 system and three StorEdge A1000 RAID units. Total storage capacity is over 3.5 Terrabytes.

Our systems are running Solaris 9 and 10, Oracle 9i and 10g Enterprise DBMS with Oracle Spatial, and the latest versions of ArcIMS, ArcSDE, Apache, Jakarta Tomcat, Lyris ListManager, WebObjects, and Summary Plus. Our map services comply with the OpenGIS Web Mapping Services 1.1.1 standard. We also are using a variety of other open source software (OSS).

Our web-mapping research and development system consists of two Sun Fire V100 servers and several Windows and Mac OS X workstations.

To guarantee security for the servers, all systems are maintained to the current stable patch levels, and each server is scanned regularly for vulnerabilities.

One of SunSITE's primary goals, with regard to all its resources, is to provide reliable 24x7x365 service. To assure this, we have taken the following steps:

SunSITE@utk is housed in one of the university's primary computer centers, which has uniterruptible power supplies, a backup diesel generator, and an autonomous backup air conditioning system.

The University of Tennessee is currently connected to the Internet via a 622MB/s OC-12 (90MB/s via Internet 1, 532MB/s via Internet 2). Each server is connected to a redundant network backbone via a 100MB/s link. (An additional dedicated 155MB/s DS-3 is available for on-campus student residences.)

The University of Tennessee's Center for Computational Sciences and the Joint Institute for Computational Science (with Oak Ridge National Laboratory) have a long history of advancing high-performance computing and networking in support of science and education. JICS also is the home of GLORIAD, the network for global cooperation in science and education.
