Forum OpenACS Q&A: Re: OT: Dell PowerEdge RAID 10 Configuration
The workload is mostly read with some large batch reads. No large batch writes. The database does have a large amount of clob data.
In most cases I would say for the same money you are better off with more memory and raid 5 than less memory and raid 10. The problem is in the current world unless you run 64bit you can't get very much memory in a machine and drives are so large it does not take very many.
For cheap and fast I'd run dual AMD 64 with 2 SATA drives mirrored. You could get up to 16gig of memory and 250gig of disk for maybe 5K but no Oracle 64 bit support yet.
