Chapter 6: Management with the CLI

Summary

The config command has two options: Automatic and Express.

Automatic configuration takes all available unconfigured physical drives to create an optimized disk array following a default set of parameters. There are no options.

Express configuration takes your input, creates one or two arrays, and spreads their capacity evenly over all of the logical drives that you specify.

The redundancy option creates redundant logical drives (RAID 1, 10, 1E, 5, 50, 6, or 60).

The capacity option enables optimizes the logical drives for capacity. The performance option optimizes the logical drives for performance.

If you choose all three options, redundancy gets highest priority and capacity gets lowest priority.

Automatic configuration with no options.

Creates an optimized disk array. One or more logical drives are created automatically.

Express configuration. RAID level is dependant on the options chosen.

Selects the redundancy option. Selects the performance option. Selects the capacity option.

Allows mixing SATA and SAS physical drives in the same array.

Includes a spare drive in the array.

Note: Requires 5 or more unconfigured physical drives. Specifies the intended application for this array. Sequential large block reads.

Random read/write mix, small to medium sized IO. Sequential small block write.

Random read/write mix, small to medium sized IO. Random read/write mix, small to medium sized IO.

Specifies how many logical drives to include in the configuration. Array capacity is divided evenly among the logical drives.
