The system consists of one main file server called Caesar and a set of client drones. The units are 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. Access to the room is on a need basis and Professor Jonas is the key holder. 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.

List of Machines

 * NOTE - Lutetia is on a different subnet, can only be accessed via ROME as ROOT on Rome's Secondary IP

For OS Release number: cat /etc/redhat-release

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.

 * Total Memory: Memory per (# free -m)
 * Total Disc Space: Total Disc space per (# df -h)
 * Used Disc Space: Used Disc space per (# df -h)
 * OS version: Which operating system is installed

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 (132.177.189.63). 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.
