WebPAM User Manual Spare Drives A spare drive is a physical drive designated to function as a hot spare drive. A hot spare drive automatically replaces a failed physical drive. You can also set the Controller to rebuild a logical drive from a Free disk drive. See “Controller Settings” on page 49 and “Logical Drive Rebuild” on page 70 for more information on how spare drives work. Spare Drive View Spare Drive View provides a list of all spare drives currently on the Host PC.

From the Logical Drive dropdown menu, select • Global Spare – This Spare Drive can be used by any qualified Logical Drive. • Logical Drive – The name of the logical drive to which this Spare Drive will be assigned or dedicated. Click on a disk drive to select it. Available drives have a black frame. Selected drives have a red frame. Drives with a blue frame are assigned to a logical drive. You cannot assign a split drive as a spare drive. 5.

Check the box to the left of the spare drive you want to delete. 4. Click the Delete button. 5. In the Confirmation box, click the OK button. The selected spare drive is deleted.

WebPAM User Manual RAID 0 – Stripe When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple disk drives. Performance is increased, since the workload is balanced between drives or “members” that form the logical drive. Identical drives are recommended for performance as well as data storage efficiency. The logical drive's data capacity is equal to the number of drive members multiplied by the smallest logical drive member's capacity.
Chapter 6: Technology Background RAID 1 – Mirror When a logical drive is mirrored, identical data is written to a pair of disk 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. Whichever drive is not busy and is positioned closer to the data will be accessed first. With RAID 1, if one disk drive fails or has errors, the other mirrored disk drive continues to function.
WebPAM User Manual RAID 10 – Mirror / Stripe Mirror/Stripe combines both of the RAID 0 and RAID 1 logical drive types. It can increase performance by reading and writing data in parallel while protecting data with duplication. At least four disk drives are needed for RAID 10 to be installed. With a four-disk-drive logical drive, one drive pair is mirrored together then striped over a second drive pair. Data Stripe Data Mirror Disk Drives Figure 3.
Chapter 6: Technology Background JBOD – Single Drive Just a Bunch of Disks (JBOD) arranges individual physical drives on the ATI SB600 Controller controller the same as if they were attached to the PC’s motherboard controller. The advantage is that the ATI SB600 Controller can accommodate up to four physical drives, more than most PC motherboards. JBOD offers none of the performance or security advantages of a RAID logical drive.
WebPAM User Manual Choosing a RAID Level There are several issues to consider when choosing the RAID Level for your logical drive. The following discussion summarizes some advantages, disadvantages, and applications for each choice.
Chapter 6: Technology Background RAID 10 Advantages Disadvantages Implemented as a mirrored logical drive Very high disk overhead - uses only whose segments are RAID 0 logical 50% of total capacity drives High I/O rates are achieved thanks to multiple stripe segments Recommended Applications for RAID 10 • Imaging applications • Database servers • General fileserver JBOD Advantages Disadvantages Easy management of multiple No increase in performance, capacity or fault tolerance.
WebPAM User Manual Choosing Stripe Block Size For RAID 0 and RAID 10 logical drives, the stripe block size value can be set to 64 KB or 128 KB. 64 KB is the default. This selection will directly affect performance. There are two issues to consider when selecting the stripe block size. • Choose a stripe block size equal to or smaller than the smallest cache buffer found on any disk drive in your logical drive.
Chapter 6: Technology Background Hot Spare Drive(s) A hot spare is a disk drive that is connected to the logical drive system but is not assigned as a member of the logical drive. In the event of the failure of a drive within a functioning fault tolerant logical drive, the hot spare is activated as a member of the logical drive to replace a drive that has failed. The ATI SB600 Controller will replace a failing disk drive in a logical drive with an unassigned drive, if one is available.
WebPAM User Manual You can change the RAID level of a logical drive with certain combinations of RAID level and number of physical drives, as described in the table below.
Chapter 6: Technology Background address blocks or sectors. This limitation does not apply to Windows XP (64-bit), 2003 Server, Vista, and Linux OSes with the 2.6 kernel. For Windows 2000 and Windows XP (32-bit), multiply the number of blocks by the sector size to find the capacity of a logical drive: 4,000,000,000 blocks x 512 bytes per sector = 2,048,000,000,000 bytes of data for a 2TB drive.

WebPAM User Manual Why do the Rebuild, Synchronize, Expand, and Migrate operations take so long compared to moving data? When data is moved, the operation consists of reading, writing, and checking one or more files. Rebuild, Synchronize, Expand, and Migrate involve reading, writing, and checking all the logical block addresses or individual data blocks on each disk drive. Plus, your disk array remains available while these operations take place.
Appendix B: Partition and Format In order for your operating system to recognize and work with the disk drives attached to your ATI SB600 Controller, the drives must be partitioned and formatted.
