I have no experience with Sql 2005 and am finally jumping into from Sql2k. Setting up a brand new install for client of mine and would love to hear some recommendations for the correct set up. Server: Dell PowerEdge R900 4x Quad Core X7350 Xeon, 2.93GHz, 8M Cache 32GB Memory 2x 36G 15k SCSI Drive Shelf: Dell PowerVault MD3000 2x 36G 15k SAS 2x 73G 15k SAS 11x 300G 15k SAS OS/DB: Win 2003 Ent. SQL 2005 Ent. Data is: 90% eCommerce & statistical data (35% reads, 65% writes) 10% cross-selling data stored separately for faster reads (90% read, 10% write) The eCommerce non-text inventory & sales data is expected to grow 6M rows/10Gb per month (each) in 5 separate tables. The text columns will grow 25G per month. There is one table with varchar(75) and one with a text column, each will have its own Full Text Index. The cross-selling data has no more than 500k rows at any one time which can be lost and quickly created at any time, so Raid 5 is not needed. I'm thinking that the correct Raid config would be as follows: Server: OS 2x 36G Raid 1 Drive Shelf: tempdb 2x 36G Raid 1 translogs 2x 73G Raid 1 eCommerce data 5x 300G Raid 5 Cross-selling data 2x 300G Raid 1 Statistical data 2x 300G Raid 1 Hot Spare 2x 300G Another question I had was can I/should I do Raid 6 instead of 5? I'm thinking that I will eventually create a table(s) partition. Any help on this set up would be greatly appreciated.
