This page provides some diagrams and information about how our server systems and virtual machines are organized. For detailed information about our network layout, see the network page.

Systems Diagram

Here is a diagram of our current system layout.

System layout current.png

Black Systems represent physical hardware.

Blue Systems represent Virtual Machines

Arrows indicate which system a Virtual Machine is running on. Other hosts with VMWare capability can be used to fill in for the main Virtualization server during downtime.

Operating System is listed in italics beneath each system's name

Services are listed in the second row of the diagram, followed by the name of the software used to provide that service.

System Descriptions

Brief descriptions of our computing systems. For more detailed information see the servers and workstations page.

Server Hardware

Endeavour is a 26-node beowulf cluster.

Gourd is a 2U rackmount server from Microway with two Quad-Core AMD Opteron processors and 32 GB of memory. It is the workhorse of the NPG server farm, hosting user's home folders as well as acting as the primary host for kvm virtual machines.

Lentil is our backup server, and it is a custom built Dual-Core Pentium D machine with 2 GB of memory.

Pumpkin is a Microway 5U rackmount server with four Dual-Core AMD Opteron processors and 32 GB of memory. It is used primarily for data storage and computation.

Taro is a computation and data storage server with two Quad-Core Intel Xenon processors and 24 GB of memory. It also serves as a secondary host for virtual machines.

Tomato was previously Einstein, and now is a secondary DNS server and kvm host.
