P.S. raid 5 is ok for general use - read is pretty good. Write is twice as slow. Raid 5 is also based on striping which can take a while to recover a dead disk - basically has to realign across all disks. Raid 5 is not good for databases.<br />

For your OS, you can use a RAID 5. &nbsp;For where you place your data files and log files, your best bet is to use RAID 10 if you can afford it. &nbsp;It is a lot faster than RAID 5, and is fault tolerant. &nbsp;<br />
<br />
Also, you'll want to place your log files and data files in seperate containers if possible, as the log is written to sequentially, and the data files and written to/read from randomly.

We are looking at buying a new database server and I would like to know the best raid setup to use. &nbsp;I have read rad 1 for the os, another raid 1 for the logs and a raid 10 for the database.<br />
<br />
Cost is always a concern so to curb costs I will either needs to do 1 raid 5 or 1 raid 10. &nbsp;The OS/Database/ and logs would all be on the chosen raid.<br />
<br />
So is 1 raid 10 better than 1 raid 5 with a hotspare?<br />
<br />
Thanks,

What raid to choose for OS and Database

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

Microsoft SQL Server

Microsoft SQL Server 2005 is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning. It includes support for managing XML data and allows a database server to be exposed over web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests.
