Page 341: Raid 1E – Enhanced Mirror
Chapter 9: Technology Background RAID 1E – Enhanced Mirror RAID 1E offers the security of mirrored data provided by RAID 1 plus the added capacity of more than two physical drives. It also offers overall increased read/ write performance plus the flexibility of using an odd number of physical drives. With RAID 1E, each data stripe is mirrored onto two physical drives.
Page 342: Raid 3 – Block Stripe And Dedicated Parity
100 GB physical drives will have a capacity of 300 GB. A RAID 3 logical drive with two 120 GB physical drives and one 100 GB physical drive will have a capacity of 200 GB. A RAID 3 on ASUS Storage consists of 3 to 32 physical drives.
Page 343: Raid 5 – Block And Parity Stripe
120 GB physical drives and one 100 GB physical drive will have a capacity of 200 GB. RAID 5 is generally considered to be the most versatile RAID level. A RAID 5 on ASUS Storage consists of 3 to 32 physical drives.
Page 344: Raid 6 – Block And Double Parity Stripe
RAID 6 provides double fault tolerance. Your logical drive remains available when up to two physical drives fail. RAID 6 is generally considered to be the safest RAID level. A RAID 6 on ASUS Storage consists of 4 to 32 physical drives.
Page 345: Raid 10 – Mirror / Stripe
RAID 10 can increase performance by reading and writing data in parallel or striping, while protecting data by duplicating it or mirroring. ASUS implements RAID 10 by creating a data stripe over one pair of disk drives, then mirroring the stripe over a second pair of disk drives. Some applications refer to this method as RAID 0+1.
Page 346: Raid 30 – Striping Of Dedicated Parity
Chapter 9: Technology Background RAID 30 – Striping of Dedicated Parity RAID 30 combines both RAID 3 and RAID 0 features. Data is striped across physical drives as in RAID 0, and it uses dedicated parity as in RAID 3. RAID 30 provides data reliability, good large file read, and high transfer rate performance.
Page 347: Raid 50 – Striping Of Distributed Parity
Chapter 9: Technology Background RAID 50 – Striping of Distributed Parity RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across physical drives as in RAID 0, and it uses distributed parity as in RAID 5. RAID 50 provides data reliability, good overall performance, and supports larger volume sizes.
Page 348 Chapter 9: Technology Background RAID 30 and 50 Axles When you create a RAID 30 or RAID 50, you must specify the number of axles. An axle refers to two or more RAID 3 logical drives striped together to make a RAID 30.
Page 349: Raid 60 – Striping Of Double Parity
Chapter 9: Technology Background RAID 60 – Striping of Double Parity RAID 60 combines both RAID 6 and RAID 0 features. Data is striped across disks as in RAID 0, and it uses double distributed parity as in RAID 6. RAID 60 provides data reliability, good overall performance and supports larger volume sizes.
Page 350 Chapter 9: Technology Background RAID 60 Axles When you create a RAID 60, you must specify the number of axles. An axle refers to a single RAID 6 logical drive that is striped with other RAID 6 logical drives to make RAID 60. An axle can have from 4 to 16 physical drives, depending on the number of physical drives in the logical drive.

Page 355: Choosing Stripe Size
Stripe Size. If you do not know the cache buffer or fixed data block sizes, ASUS suggests you choose 64 KB as your Stripe Size. Generally speaking, email, POS, and Web Servers prefer smaller stripe sizes.
Page 356: Tb Limitation
Cache Policy As it is used with ASUS Storage, the term cache refers to any of several kinds of high-speed, volatile memory that hold data moving from your computer to the physical drives or vice-versa. Cache is important because it can read and write data much faster than a physical drive.
Page 357: Read Cache Policy
Write Back. Forced Read-Ahead Cache On the ASUS Storage subsystem, you can set the logical drive read cache policy to Forced Read Ahead an enable the aggressive pre-fetch feature. The Forced Read-Ahead cache policy setting provides predictive pre-fetching of data requests, allowing the controller to aggressively buffer large chunks of data in cache memory to prevent frame drops on high-bandwidth video playback.
Page 358: Capacity Coercion
With ASUS Storage, you can choose to enable Capacity Coercion and any one of four methods.
Page 359: Hot Spare Drive(S)
ASUS Storage will replace a failing disk drive in a disk array with an unassigned drive, if one is available. The unassigned drive is not part of any disk array. Such a drive is called a hot spare drive.
Page 360: Partition And Format The Logical Drive
Chapter 9: Technology Background ASUS Storage includes a function that enables you to return a hot spare drive from a disk array back to spare status. When you create the hot spare drive, check the Revertible box to enable this feature. See ―Transition‖ on page 352.
Page 361 Chapter 9: Technology Background RAID 0 A RAID 0 source logical drive can migrate to the following target logical drives: Target Requirements RAID 0 Add physical drives. RAID 1 2 physical drives only. Only a single-drive RAID 0 can migrate to RAID 1 by adding 1 physical drive.

Page 368: Ranges Of Disk Array Expansion
Note that once you create your logical drive, you cannot change the size of the sectors. Nor can you increase the number of address blocks that the OS recognizes. You can direct ASUS Storage Management to expand a logical drive beyond the maximum expansion size. When the expansion is finished: •...
Page 369: Media Patrol
Backup the data from the current logical drive. Delete the current logical drive. See page 158 (ASUS Storage Management) or page 235 (CLU). Create a new logical drive with the desired capacity. See page 156 (ASUS Storage Management) or page 234 (CLU).
Page 370: Predictive Data Migration (Pdm)
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. See ―Running PDM‖ on page 71 (ASUS Storage Management) or page 233 (CLU).
Page 371 Transition The Transition feature enables you to specify ―permanent‖ spare drives for your ASUS Storage 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. The revertible spare drive returns to its original status.
Page 372 Chapter 9: Technology Background Example Following is an example to explain the Transition function. 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.
Page 373 At this juncture, you would replace the failed drive in slot 3 with a new one of the same or greater capacity. When the ASUS Storage controller detects the new drive in slot 3, it will: • Automatically transition the data on drive 6 to drive 3 •...
