Old Hardware Configuration (no longer exists)

 * The system consists of 1 Dell PowerEdge 2650 fileserver named Caesar and 9 Dell PowerEdge 1750 queue clients named after characters in the French Asterix and Obelix comic book series (using German translation names). The physical hardware components are located in a locked room in the UNHM CIS lab back room (room number XX). Access to the room is on a need basis and Professor Jonas is the key holder. Looking at the server rack, Caesar is on the top and the 9 clients are directly below. The system is connected to the UNH network via Caesar's access card. The hardware itself is dated, but functionally sound and in good condition. No future upgrades are planned at this time.

Description of Fields

 * Hardware Component Name:
 * CPU Speed: CPU Processor information and top speed (# grep "model name" /proc/cpiunfo) Note: Four Processors are displayed with this command. However our system only has 2 processors per component, but each processor displays 2 virtual processors.
 * http://us.generation-nt.com/answer/2-processors-show-4-redhat9-help-173485141.html
 * Total Memory: Memory per (# free -m)
 * Total Disc Space: Total Disc space per (# df -h)
 * Used Disc Space: Used Disc space per (# df -h)
 * Functionality: System test passed
 * Usability: Students feedback, responsiveness of components, and researched analysis of hardware needs versus system needs
 * Estimated Market Value: Mean Value of Google Search on replacement hardware
 * Upgrade Options: Analysis of hardware needs versus system needs

Rack and Network Configuration

 * The 10 servers reside in a half height rack with Caesar connecting to UNHM's network (the 132.177.188.0) on eth0 (132.177.188.63). Caesar's eth1 port is connected to a dell switch located in the back of the rack which provides local connectivity between caesar and the rest of the batch servers in the 192.168.10.0 address space. For more information on the network bridge setup see the "Network Bridge" page. Through the local network, the clients are able to mount to Caesar's raid array. A KVM switch has been installed at the top of the stack which provides desktop access to each server in the rack.
