the storage doctors
December, 2006
Hello and welcome to the December 2006 edition of Bell Micro's Bellcast: a show designed to help you get up to speed on the latest in server and storage products, especially those that take advantage of Apple technologies.
What we are trying to do with these broadcasts is to help everyone get a better understanding of storage and server offerings as well as highlight products and applications from different manufacturers that add value to the basic technology.
We hope to make these Bellcasts available on a monthly basis. Let us know if there is a specific topic you would like covered by sending us an email at assistance@bellmicro.com
To get everyone off on an equal footing, this first show goes over the basics of RAID: what it is, what it offers, and how to apply it. I will also include a description of Apple's Xraid offering and why we think it deserves a closer look from any VAR or customer looking for RAID.
- RAID 0 divides the data into various drives, improving performance with no redundancy(stripping).
- RAID 1 makes an exact copy of the data from ones hard disk to another (mirroring).
- RAID 3 uses striping and the parity information is sent to a dedicated parity disk.
- RAID 5 makes uses stripping at the byte level, but the parity information is distributed in more than one disk (distributed parity).
