Notes 1. Hard disk drive capacities influence the way you create arrays. Drives in the array can be of different capacities, but the ServeRAID controller treats them as if they all have the capacity of the smallest disk drive. (See "Hard disk drive capacities" on page 81 for more information.) 2. If you change your mind after selecting the drives for an array, you can delete the array (by selecting Delete Disk Array from the Create/Delete Copy Log Drive menu); then, begin again. 5. After you select all of the drives that you want to include in the array, press Esc to return to the Create/Delete Copy Log Drive menu. Note When the stripe-unit size is 8 K (the default setting) or 16 K (a manual setting), the maximum number of physical drives in an array is 16. When the stripe-unit size is 32 K or 64 K (both are manual settings), the maximum number of physical drives in an array is eight. 6. If you want to create another array, return to step 3 on page 104. Otherwise, continue with step 7. 7. You must define at least one logical drive for each new array. Continue with "Defining logical drives." Defining logical drives: You must define at least one logical drive for each array. The ServeRAID controller supports up to eight logical drives. If you have only one array, you can define it as a single logical drive, or you can divide it into several logical drives. If you have two or more arrays, each array can be one logical drive, or you can divide each array into multiple logical drives, as long as the total number of logical drives for all of the arrays does not exceed eight. Note Refer to the documentation provided with the operating system for information about the recommended logical drive size. To define a logical drive: 1. Select Define Logical Drive from the Create/Delete/Copy Log Drive menu; then, press Enter. 2. Use the Up Arrow (↑) or Down Arrow (↓) key to highlight the array for which you want to define a logical drive; then, press Enter. Netfinity 5500 - Type 8660 105
