    How to configure RAID 5 sys using SAS controller for APP CS4

      Hi I would like to know how to configure my 3 HardDrives (600GB each) on RAID 5 connected to SAS controller to work smoothly with PremierePro CS4. Mainly to store scratch disk, and all preview files, etc.. At present it shows as one big hard drive in C:\ It shows as follows: OS(C 0.98 TB free of 1.08TB I would like to have at least one HDD out of 3 to store my scratch disk files and preview files... I have installed only CS4 Master Collection + Windows 7 64bit Ultimate as OS in this machine. Following is my system configuration: Intel Xeon E5620, 2.4GHz processor/12M Cache, 5.86GT/S, QPI, Turbo, HT, 4C Intel 5520 Chipset 12GB DDR3 RDIMM Memory,1333MHz, ECC Three 600GB (15000rpm) SAS HardDrives Perc6/i SAS/SATA Harware RAID card All SAS Drives, RAID 5, 3 drive configuration BlueRayBurner1GB PCIe X16 nVidia Quadro FX3800 ,Dual monitor DP+1 DVI Capable I am in a little bit strife on this. I am in a little bit strife on this and Open for any good and effective suggestions are much appreciated. Thanks Nathapushpa

          A 3 x 600 GB disk Raid5 array shows up as 1.08 TB capacity. That sounds about right. What does not sound right is that it shows as C:

           

          That probably means you have no separate boot disk and then you have effectively a single disk system, which is less than minimum requirements. Normally you would have your boot disk show up as C and this array as D, because the minimum requirements for CS4 stated a DEDICATED drive for editing.

           

          With only 3 HDD's, it makes more sense to remove the raid altogether and just use 3 separate non-raided drives.

            Thx Harm 4 ur advice.

             

            Do u know how to do that.??

            If I do that, then I do not have any redundency for the HDDs..isn't it?? I am not very much sure about the RAID 5 now..

            FYI, there is a spare SAS connector coming out of the SAS controller..If I connect another 600GB SAS drive can I use it as a Drive D:\ or I am just wasting my HDDs for nothing??

            Your help is much appreciated. Thx.

              You even have three more connectors free on your Perc controller, so you could add three more disks, without using any motherboard connectors.

               

              I think you have two alternative approaches:

               

              1. Add a smallish disk as a boot disk, i.e. a 150 GB Velociraptor and install OS and programs there and let your raid5 exist as it is, or

               

              2. Add another 600 GB to your raid5 to make it a four disk array.

               

              Of course you could also do both. Breaking the raid out to individual disks means that all data on the current raid will be lost, unless you have a backup available, but it will still mean a fresh install of OS & programs, so remember to deactivate Adobe before you do anything to your disk setup like in alternative 1 or breaking out the array.
