Click Delete. e A message appears confirming the deletion of the logical drive. 4. Click OK.
Marvell RAID Utility User Guide Rebuilding a Logical Drive ly 2.5 On The MRU can rebuild the logical drive by reconstructing data from a failed drive onto one of its spare physical drives. Rebuilding is available for logical drives created using RAID level 1 and 10, which have the capability of mirroring data. RAID 0 excludes rebuild capabilities. Therefore, the entire stripe is lost if one of the physical drive fails.
Marvell RAID Utility User Guide Initializing a Logical Drive ly 2.6 There are two methods for initializing a logical drive: Quick initialization. Use this method if the logical drive consists one or more disk drives. This On method erases only the Master Boot Record (MBR) in all of the selected disk drives. Full Background initialization. In this method, data synchronization occurs in the background while the operating system continues to have access to the logical drive.
Marvell RAID Utility User Guide Checking the Integrity of a Logical Drive ly 2.7 On This feature enables the software to check and fix the data parity in the logical drives using RAID levels 1 and 10. Checking the integrity of data on your logical drive is performed as a housekeeping function. Note: Perform this task when the logical drive you want to check is not performing RAID activities. To check integrity of a logical drive 1. Start the MRU. 2.

Marvell RAID Utility User Guide SELECTING A RAID LEVEL ly 4 On Redundant array of independent disks (RAID) is a storage technology consisting of one or more disks working in parallel. RAID technology allows an array of physical disks to be combined together to form a logical drive, which appears as a single storage device to the user. You can configure a RAID logical drive in several different ways, with each configuration offering its own benefits.
Marvell RAID Utility User Guide RAID 0 (Striping) ly 4.1 On RAID 0 is known as striping because data stripes of equal size on the logical drive are divided among an even number of physical disks, as shown in Figure 4-1. Consequently, the speed at which data is read and written is increased because data stored on multiple drives can be read and written simultaneously.
Marvell RAID Utility User Guide RAID 1 (Mirroring) ly 4.2 On RAID1 is known as mirroring because the data on the logical drive is written to a pair of physical disks, which ensures that identical data appears on both of the physical disks. See Figure 4-2 for more detail.
Marvell RAID Utility User Guide RAID 10 (Mirroring and Striping) ly 4.3 On RAID 10 is a combination of the mirroring (RAID 1) and striping (RAID 0) techniques. At least four physical disks (two pairs) are needed to configure a RAID 10 logical drive. Both pairs of physical disks make separate RAID 0 stripes, and then the first RAID 0 drive is mirrored to the second RAID 0 drive. See Figure 4-3 for more detail.
Marvell RAID Utility User Guide Comparing RAID Levels ly 4.4 4.4.1 On Each RAID level has features that may or may not be suitable in certain situations, so it is important to carefully consider which RAID level is best suited for a particular purpose. RAID 0 (striping) RAID 0 is simple to implement and provides increased reading and writing speed by spreading the transfer of data across multiple channels and drives.
