Storage System Facilitates Transition from Print Publishing to Electronic Publishing
The Julian Samora Research Institute was f
ounded in 1989 at Michigan State University to research relevant social, economic, educational and political conditions of Latino communities nationwide. It started out a decade ago, publishing small books and some reports. Since then, it has increased both its research and publishing volume ten times over. Up until three years ago, the institute could get away with publishing a book on paper, and then filing it away. Danny Layne, who divides his time between network administration and publishing production, recalls, “If we needed to print a book, we’d pull it out of the file and then put it away.”
To keep up with the volume of research it had to publish, the Institute found itself producing more electronic files. These files kept getting larger and more complex. Researchers, who are students at the University, broke down chapters into multiple files. One book could consist of 20 different files. Charts and graphs were also generated electronically, as were PowerPoint presentations. Books had to be published in hardcopy and also made available via the institute’s Web site. Says Layne, “ To this end, we were generating new types of files that we never had before.”
Disk space on a desktop personal computer couldn’t handle the volume being churned out. Layne asserts that they didn’t want to start adding large hard disk drives to their desktop PCs. “If one PC’s disk drive failed, then we’d have to restore files from a previous backup tape and recreate what we lost. That’s inefficient.” So, with some technology funds from the government and the university, the institute decided to buy a central storage system to house all its publications and all the files for its Web site. Since the institute has a small computing staff and limited resources, the storage device had to be highly reliable, easy to set up and maintain, and able to accommodate more storage space as needed, with the addition of more disk drives. “Our search for a storage solution brought us to Winchester Systems in Woburn, Massachusetts,” recalls Layne. “We purchased a FlashDisk external RAID storage system with seven 9-GB disk drives.”
As it appears to a user, a RAID (Redundant Array of Independent Disks) storage device functions as one big disk. Data is spread across a number of individual disks, which arise from the redundant manner in which data is stored. If any single disk in the array fails, the unit continues to function without loss of data. The redundant information can be a copy or a mathematical model of the data that was stored on the failed disk.
How It Works
Layne says that three years ago they had virtually no storage — just a few desktop PCs. “In this short time, the FlashDisk has allowed a small research department within a large university to turn itself into a publishing powerhouse on a small purse. Some of the other departments on campus are in awe of our storage system. And there are good reasons for it.”
