Regarding Proper RAID Selection
Posted on 2006-04-06
Our company is currently moving to Co-Location. We are building a slew of servers, probably from Dell.
We are a heavy SQL Based company and the multitude of computers running these seperate databases.
Some of the machines have HEAVY Reads, While some have HEAVY Writes.
I understand how RAID's work in a simple sense, I am just looking for clarification on which RAID is most Suitable for our needs.
I need proper RAID Configs from the following systems:
- For a machine with HEAVY Reads, Small Writes and Data Safety is EXTREMELY Critical
- For a machine with HEAVY Reads, Medium Writes and Data Safety is Semi-Critical
- For a machine with Extremely Heavy Reads/Writes where Data Safety is of Highest Concern
- For a machine with Very Small and Infrequent Reads/Writes where Data Safety is of minimal Concern
I am either looking for Direct Answers or General Answers Regarding RAID Configuration Tips with Emphasis in the questions that I have asked.
If anyone knows of any tools on the internet that let you pick the kinds of needs you have and then recommends a particular RAID setup that would be cool.
Thanks in advance.
