Teraserver Darrel Sharpe Matt Todd Rob Neff Mentor: Dr. Palaniappan

About the Terraserver A network server with 1000 gigabytes of storage space Designed for the MU-CECS Multimedia Lab Will run Kolam imaging software Will deliver appropriate bandwidth to authorized network users for fast loading of large images

Teraserver Goals 1)Cost under $5000 2)One terabyte of storage 3)Reliable 4)Versatile 5)Fast

The Two Best Raid Options

Hard Drive

SuperTrak66 Raid Controller

Constraints 1)A terabyte of available disk space 2)Cost around $5000 3)Able to be mounted by client MacOS, Windows, and UNIX There is no constraint on the type of OS as long as the external clients are able to mount the file share.There is no constraint on the type of OS as long as the external clients are able to mount the file share.

Performance Requirements 1)Deliver image data to workstations and other connected devices to allow for seamless scrolling of the viewed image through the Kolam software. 2)Prove the server’s reliability by staying up for months at a time.
