• How RAID 5 Works

As part of Allmar Technologies' commitment to making charitable contributions, we have created a Folding@Home team. F@H is a distributed computing project created by Stanford University in an effort to find cures for cancers and and cancer-related syndromes.

The folks at Stanford University have been studying protein folding, misfolding, aggregation, and related diseases for several years now. The overwhelming amount of data that they need to process has grown beyond what their resources can handle. This is where Allmar Technologies and you can help them out by joining the Allmar Technologies team and participating in their F@H distributed computing project.

Allmar Technologies is fanatical about uptime. To aide us in ensuring the operational integrity and high availability of your website we have deployed a data storage scheme known as RAID 5. RAID can protect uptime. RAID 5 allows a mechanical hard disk to fail while keeping your website on the array accessible to your visitors. Rather than being required to perform a time consuming restore from tape, DVD, or other slow backup media, RAID 5 allows data to be restored to a replacement disk from the other members of the array, while being simultaneously available to your website visitors. This is of high value to businesses, as downtime quickly leads to lost earning power.

This article is going to discuss how RAID 5 calculates the missing data on the failed hard drive. Since computers work in a base 2 (binary) numbering system, the math is very simple for all of us to follow. This article is by no means all inclusive, however, it demonstrates how powerful this very simple method works.
