Hi Folks Thanks for a great website, exactly what I've been looking for. I have a single database running an 85GB mdf file, and 1.5GB ldf. We have a Dell PE2900 with 12GB RAM and dual Xeon 5160 3.0GHz/4MB 1333FSB, running a RAID1 143GB SAS 15K drive partitioned into 12GB C: drive, and 124GB D: drive which I've moved the Tempdb to. The server also has a Perc 5i controller card running 8 x 143GB SAS 15K drives in a RAID10 configuration, single 544GB partition. I am running the mdf file from here. We also have a Dell MD1000 running off a Perc 5e controller card, running 8 x 143GB SAS 15K drives, single 544GB partition. Currently this is being used for the 1.5GB ldf file! As the Perc 5e controller card has 2 channels, I know I can split the MD1000 into 2 RAID10 arrays of approx 272GB each. Is it worth doing this and moving the indexes from the mdf into a seperate filgroup and onto this seperate array? It would mean the log files and indexes would be on seperate arrays, seperate channels, but the same controller card. Any thoughts?
