RAID options for a LAMP web server
- by jetboy
I'm due to set up a LAMP web server with four drives and a RAID controller to act as a web server. The drives are 146Gb SAS, and the machine has two quad core processors and 16Gb RAM.
There will be very few write operations to the MySQL database, and I'll be using as much caching as possible to reduce disk I/O.
Question is: Would I be better off splitting the drives into two RAID 1 arrays, splitting up sequential and random disk I/O, or would I get better overall performance putting them all in a single RAID 1+0 array?
