This chapter describes the user interface, and provides step-by-step instructions on using Adaptec Storage Manager to configure and manage your storage subsystem.
  • Page 9 Adaptec RAID controllers support the following types of array: RAID-0 A RAID-0 is created by striping data across two or more disk drives. Simple striping like this creates no redundancy to protect the data, but by sharing the load equally across multiple drives, it does provide the best read and write performance of any RAID type.

  • Page 10: Raid-0

    Adaptec SCSI RAID 2120S/2200S Software User’s Guide The cost of this redundancy is inefficient use of capacity, because all data is written to both drives, only half of the total capacity is available. RAID-1 offers no write performance advantage over a single drive, but read performance benefits from being able to share the load between two drives.

  • Page 11: Raid-10

    RAID-10 A RAID-10 is an example of a dual-level array and is created by using two or more equal-sized RAID-1s to create a RAID-0. RAID-1 Data 0 Data 2 Data 4 Data 6 Drive Data 0 Data 2 Data 4 Data 6 The top level RAID-0 shares the load among the second level RAID-1s, improving both read and write performance.

  • Page 13: Raid Volume

    Introduction RAID Volume A RAID volume is created by joining two or more single-level arrays of the same RAID type. Unlike dual-level arrays, the arrays in a RAID volume do not have to be of equal capacity. In direct contrast to dual-level arrays, the second-level arrays in a RAID volume are not striped together, instead they are connected end-to- end.

  • Page 22: Creating Arrays

    Adaptec SCSI RAID 2120S/2200S Software User’s Guide Creating Arrays Before creating arrays, make sure the disks for the array are connected and installed in your system (or enclosure). Note that any disks with MS-DOS partitions, disks with no usable space, or disks that are uninitialized appear dimmed and cannot be used for creating a new array.
  • Page 23 Assigning Array Properties Note that you cannot change array properties from the ACU once the array is created. To change array properties once the array is created, use Adaptec Storage Manager. To assign properties to the new array: In the Array Properties menu, select an array type and press Enter.
  • Page 24 Adaptec SCSI RAID 2120S/2200S Software User’s Guide Select the desired stripe size. The allowable stripe sizes are 16, 32, and 64 KB (the default). For RAID 50 arrays, 64 KB is the only stripe size supported by ACU. The default stripe size gives the best overall performance in most network environments.

  • Page 25: Initializing Disk Drives

    Initializing Disk Drives If an installed disk does not appear in the disk selection list for creating a new array or if it appears grayed out, you may have to initialize it before you can use it as part of an array. Caution: Initializing a disk overwrites the partition table on the disk and makes any data on the disk inaccessible.
