9. Access alignment The alignment of a command from a host system is determined by the command s address In an optimal system a write of one chunk of data would reside exactly within a chunk on one disk However if this is not the case this write will be split up into two separate writes to two different data drives This will have a negative effect on performance To overcome these problems you can with more sophisticated operating systems set the access size and alignment to an optimal value 229 Appendix A Optimizing RAID 5 Write Performance To get the highest performance from this system it is necessary to have a number of stripes being written in parallel As the array expands with more and more drives the number of commands and amount of sequential data necessary to do this increases P 56 62 C56 C57 C58 C59 C60 C61 C62 Stripe 8 C49 C50 C51 C52 C53 C54 C55 P 49 55 Stripe 7 c2 C43 C44 C45 C46 C47 P 42 48 C48 Stripe 6 C35 C36 C37 C38 C39 P 20 23 C61 C62 Stripe 5 C28 C29 C30 C31 P 28 34 C22 C33 C34 Stripe 4 C21 C22 C23 P 21 27 C24 C25 C26 C27 Stripe 3 C14 C15 P 14 20 C16 C17 C18 C19 C20 Stripe 2 C7 P 7 13 C8 C9 C10 Cll C12 C13 Stripe 1 P 0 6 C0 C1 C2 C3 C4 C5 C6 Stripe 0 In this table we can see that seven chunks of sequential data are necessary to fill a stripe To have multiple commands active for all hard drives requires

Using a RAID 5 array example adding more drives to the array lets you increase the capacity of that array If you add additional sub arrays it requires the exact number of drives to be available for the original sub array For example if you have an array composed of 4 data drives and 1 parity drive you must have a minimum of five drives available to be able to add at least 1 sub array When you view the array configuration information the RAID type and number of drives are displayed These drives are depicted as data drives plus parity drives In this example it would be displayed as 4 Drives 3 1 which indicates the array sub array is composed of 4 drives of which 3 are data drives and 1 is a parity drive If you were to add 1 sub array to this particular configuration the resulting display would be 8 Drives 6 2 in which case you now have 6 data drives and 2 parity drives Your RAID 5 array now becomes a RAID 50 array because it s composed of two sub arrays each sub array has three data drives and one parity drive If you are expanding a RAID 50 array by adding drives to the array you must add an equal number of drives to each sub array The process of expanding the array by adding additional sub arrays allows for quicker recoveries in the event of a drive failure in any one of the sub arrays and the time required to rebuild the array is significantly shortened To add more drives to your existing arrays refer to Add
