Page 236: Raid 0 - Stripe
VTrak E-Class Product Manual RAID 0 – Stripe When a disk array is striped, the read and write blocks of data are interleaved between the sectors of multiple drives. Performance is increased, since the workload is balanced between drives or “members” that form the disk array. Identical disk drives are recommended for performance as well as data storage efficiency.
Page 237: Raid 1 - Mirror
Chapter 7: Technology Background RAID 1 – Mirror When a disk array is mirrored, identical data is written to a pair of drives, while reads are performed in parallel. The reads are performed using elevator seek and load balancing techniques where the workload is distributed in the most efficient manner.
Page 238: Raid 1E - Enhanced Mirror
VTrak E-Class Product Manual RAID 1E – Enhanced Mirror RAID 1E offers the security of mirrored data provided by RAID 1 plus the added capacity of more than two disk drives. It also offers overall increased read/write performance plus the flexibility of using an odd number of disk drives. With RAID 1E, each data stripe is mirrored onto two disk drives.
Page 239: Raid 5 - Block And Parity Stripe
Chapter 7: Technology Background RAID 5 – Block and Parity Stripe RAID 5 organizes block data and parity data across the physical drives. Generally, RAID Level 5 tends to exhibit lower random write performance due to the heavy workload of parity recalculation for each I/O. RAID 5 is generally considered to be the most versatile RAID level Distributed Parity Data...
Page 240: Raid 6 - Block And Double Parity Stripe
VTrak E-Class Product Manual RAID 6 – Block and Double Parity Stripe RAID level 6 stores dual parity data is rotated across the physical drives along with the block data. A RAID 6 disk array can continue to accept I/O requests when any two physical drives fail.
Page 241: Raid 10 - Mirror + Stripe
Chapter 7: Technology Background RAID 10 – Mirror + Stripe Mirroring/striping combines both of the previous RAID 1 and RAID 0 disk array types. RAID 10 is similar though not identical to RAID 0+1. RAID 10 can increase performance by reading and writing data in parallel while protecting data with duplication.
Page 242: Raid 50 - Striping Of Distributed Parity
RAID 50 arrays consist of six or more physical drives. Using a VTrak E310f/s subsystem expanded by four J300s subsystems, your RAID 50 array supports up to 60 physical drives. See “Configuring JBOD Expansion” on page 18 or page 24. However, Promise recommends that you set aside a few physical drives as hot spares.

Page 249: Choosing Stripe Size
Chapter 7: Technology Background Choosing Stripe Size Stripe Size, also called “Stripe Block Size”, refers to the size of the data blocks written to, and read from, the physical drives. Stripe Size is specified when you create a disk array. In order to change the Stripe Size of an existing disk array, you must delete the disk array and create a new one.
Page 250: Tb Limitation
VTrak E-Class Product Manual • Linux operating systems with the 2.6 kernel support 64-bit LBA. For these OSes, always choose the default 512 B sector size. 2 TB Limitation If your Host PC runs Windows 2000 or Windows XP (32-bit), and you want to create logical drives larger than 2TB, you must choose a sector size larger than 512 B when you create the logical drive.

Page 252: Lun Affinity
VTrak E-Class Product Manual LUN Affinity VTrak Fibre Channel subsystems with two controllers include a LUN Affinity feature. Normally, either controller can access all logical drives. LUN Affinity enables you to specify which controller can access each logical drive. Use this feature to balance the load of your logical drives between the two controllers.
Page 253: Failover And Failback
Chapter 7: Technology Background Failover and Failback When one controller fails, the surviving controller takes over logical drive access until the failed controller is brought back online or is replaced. For example, LUN Affinity is enabled and your logical drives are assigned to Controller 1. The following actions will happen: •...
Page 254: Initialization
VTrak E-Class Product Manual Without Capacity Coercion, the controller will not permit the use of a replacement physical drive that is slightly smaller than the remaining working drive(s). Initialization Initialization is done to logical drives after they are created from a disk array. Initialization sets all data bits in the logical drive to zero.
Page 255: Partition And Format The Logical Drive
Chapter 7: Technology Background Partition and Format the Logical Drive Like any other type of fixed disk media in your system, a RAID logical drive must also be partitioned and formatted before use. Use the same method of partitioning and formatting on an logical drive as you would any other fixed disk. Depending on the operating system you use, there may or may not be various capacity limitations applicable for the different types of partitions.

Page 259: Predictive Data Migration (Pdm)
Chapter 7: Technology Background Predictive Data Migration (PDM) Predictive Data Migration (PDM) is the migration of data from the suspect disk drive to a spare disk drive, similar to Rebuilding a Logical Drive. But unlike Rebuilding, PDM constantly monitors your disk drives and automatically copies your data to a spare disk drive before the disk drive fails and your Logical Drive goes Critical.
Page 260: Transition
VTrak E-Class Product Manual Transition The Transition feature enables you to specify “permanent” spare drives for your VTrak subsystem. Transition is the process of replacing a revertible spare drive that is currently part of a disk array with an unconfigured physical drive or a non- revertible spare.
Page 261 Chapter 7: Technology Background In the example above, there is a four-drive RAID 5 disk array and a global spare drive. Physical drives 1, 2, 3, and 4 belong to the disk array. Physical drive 5 remains unconfigured. Physical drive 6 is a revertible spare drive. If a physical drive fails in a disk array and there is a spare drive of adequate capacity available, the controller automatically rebuilds the array using the spare drive.

Page 290: Critical & Offline Disk Arrays
VTrak E-Class Product Manual Critical & Offline Disk Arrays A fault-tolerant disk array—RAID 1, 1E, 5, 10, and 50—goes critical when a disk drive is removed or fails. A RAID 6 or 60 disk array—goes degraded when a disk drive is removed or fails and critical when two disk drives are removed of fail. Due to the fault tolerance of the disk array, the data is still available and online.
Page 291: Without A Hot Spare Drive
Chapter 8: Troubleshooting After the disk array rebuilds itself using the spare drive, you must replace the failed drive. To set up a spare drive, see “Creating a Spare Drive” on page 135 (WebPAM PROe) or page 181 (CLU). Without a Hot Spare Drive If there is no hot spare drive of adequate capacity, you must remove the failed drive and install an unconfigured replacement drive of the same or greater capacity in the same slot as the failed drive.
