[. . . ] The drives required per RAID level is RAID Level 0 1 10 Minimum Number of Drives Maximum Number of Drives One Two Four Four Two Four 82 5 Configuring IDE Software RAID Selecting a RAID Level To ensure the best performance, you should select the optimal RAID level when you create a system drive. The optimal RAID level for your disk array depends on the following factors: · · · · Number of drives in the disk array Capacity of the drives in the array Need for data redundancy Disk performance requirements The factors you need to consider when selecting a RAID level are listed below. RAID Level 0 Description and Use Data divided in blocks and distributed sequentially (pure striping). Use for readintensive fault tolerant systems Data divided in blocks and distributed sequentially and each block is duplicated to another disk. Pros Cons Number of Drives One to Four Fault Tolerant No High data throughput for large files. No fault tolerance. All data lost if any drive fails. 1 100 percent data redundancy Double disk space. Reduced performance during rebuilds. Two Yes 10 100 percent data redundancy and High data throughput. A minimum of four drives required. Four Yes 83 Configuring Arrays After you have enabled IDE Software RAID in BIOS and have attached all physical disk drives, perform the following actions to prepare a RAID disk array Step 1 2 3 4 5 Action Press <CTRL>+<M> to run the IDE Software RAID Manager Define and configure one or more logical drives. After initialization, you can install the operating system. Creating a Mirrored Array From an Existing Drive To build a new mirrored array from an existing drive, connect the current drive and a new drive to the RAID card. · · · Turn on the computer and Press <CTRL>+<M> to start the IDE Software RAID manager. You can identify the existing drive and the new drive by their connection location. select the newly connected drive as the target drive by pressing <SPACE> and then <ENTER>. If there are any errors during the building of the array, you will be prompted with a message box. The SPARE POOL option is not a RAID mode, but a way to assign a physical drive as a hot spare to be used n case of a mirror failure. When a mirror configured array has a drive failure, a spare drive can be used to replace the failed drive and rebuild the array. Note: To rebuild a drive from the SPARE POOL, the size of the physical drive in SPARE POOL must be the same or larger than the smallest drive in the array. 87 Drive(s) - There is no default setting for this field. When this field is selected, a pop-up window will display all the available physical drives with check boxes. Drive Selection Box [] [] [] [] Cntlr 0 - Primary Master Cntlr 0 - Primary Slave Cntlr 0 - Secondary Master Cntlr 0 - Secondary Slave Use the arrow navigation keys and press <SPACE> to select or deselect the drive or drives to be put into the array. If you select Mirror mode as the array type, you must select two drives to be in the array. This pop-up window will appear only when configuring RAID 0 (Stripe) and RAID 1 (Mirror) arrays. A RAID 10 array contains drives in each Stripe of the array and only two drives are allowed in each stripe. The size options are: · · · · · · · · 32 KB 64 KB 128 KB 256 KB 512 KB 1024 KB 2048 KB 4096 KB Note: You cannot change the Stripe size of an array that has already been configured. Bootable - This determines which of the configured arrays should be used for booting the system. Only one array is allowed to be bootable in a system. 88 5 Configuring IDE Software RAID Drive Size - This field cannot be edited. When the array type is Stripe, the drive size is the total of all the drives selected (one or more drives). When Mirror, drive size is shown by an individual drive, and for Spare Pool, drive size shows the total drive capacity. Build Array - The build array option is valid for RAID 1 (Mirror) and RAID 10 arrays only.
