Page 215 Pegasus32 Product Manual Troubleshooting Overheating Overheating is a potentially serious condition because the excessively high temperatures can lead to physical drive failure and controller malfunction. Overheating usually results from: • Fan failure • Inadequate air circulation around the Pegasus unit Fan Failure The larger fan on the back of the Pegasus unit cools the physical drives and the RAID controller.
Page 216 Promise Technology Pegasus32 R4/R6/R8 Inadequate Air Circulation Air circulation around the Pegasus unit might be a more complex problem. Check for these conditions: • Accumulated dust or objects blocking the fans. • Less than a minimum of 13 cm (5 inches) space between the back of the unit and the wall or other object.

Page 221: Disk Arrays
Pegasus32 Product Manual Technology Background Disk Arrays Disk array technology includes: • Media Patrol • Media Patrol Media Patrol is a routine maintenance procedure that checks the magnetic media on each disk drive. Media Patrol checks all physical drives assigned to disk arrays and spare drives. Media Patrol does not check unconfigured drives.
Page 222 Promise Technology Pegasus32 R4/R6/R8 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 223: Technology Background
Pegasus32 Product Manual Technology Background Logical Drives Logical drive technology includes: • “RAID Levels” • “RAID Level Migration” • “Stripe Size” • “Sector Size” • “Initialization” RAID Levels RAID (Redundant Array of Independent Disks) allows multiple physical drives to be combined together in a disk array.
Page 224 Promise Technology Pegasus32 R4/R6/R8 The disk array’s data capacity is equal to the number of disk drive members multiplied by the smallest drive’s capacity. For example, one 100 GB and three 120 GB drives form a 400 GB (4 x 100 GB) disk array instead of 460 GB.
Page 225: Raid 1 - Mirror
Pegasus32 Product Manual Technology Background RAID 1 – Mirror When a logical drive is mirrored, identical data is written to a pair of physical 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 is accessed first.

Promise Technology Pegasus32 R4/R6/R8 RAID 60 – Double Parity + Stripe The PROMISE RAID 60 combines RAID 6 distributed (double) parity and RAID 0 block-level striping. RAID 60 can increase performance by reading and writing data in parallel or striping, while simultaneously providing parity.
Page 233: Raid Level Migration
Pegasus32 Product Manual Technology Background RAID Level Migration The term “Migration” means either or both of the following: • Change the RAID level of a logical drive. • Expand the storage capacity of a logical drive. On Pegasus, RAID level migration is performed on the disk array but it applies to the logical drives. Migration does not disturb your data.
Page 234 Promise Technology Pegasus32 R4/R6/R8 RAID 1 A RAID 1 Source logical drive can migrate to the following T arget logical drives: Target Requirements None. RAID 0 3 or more physical drives. RAID 1E Add 1 or more physical drives. 3 physical drives minimum, maximum 4 (R4), 6 (R6) or 8 (R8).
Page 235 Pegasus32 Product Manual Technology Background RAID 1E A RAID 1E Source logical drive can migrate to the following T arget logical drives: Target Requirements None. RAID 0 Add physical drives. RAID 1E 3 physical drives minimum, 4 (R4), 6 (R6) or 8 (R8). RAID 5 RAID 1E must have less than 4 (R4), 6 (R6) or 8 (R8) physical drives.

Page 238: Stripe Size
Promise Technology Pegasus32 R4/R6/R8 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 logical drive. You can choose Stripe Size directly when you use the Wizard Advanced Configuration function to create a logical drive. You cannot change the Stripe Size of an existing logical drive. You must delete the logical drive and create a new one.
Page 239: Sector Size
Pegasus32 Product Manual Technology Background Sector Size A sector is the smallest addressable area on a physical drive. Sector size refers to the number of data bytes a sector can hold. A smaller sector size is a more efficient use of a physical drive’s capacity. 512 bytes (512 B) is the most common sector size, and the default in the Pegasus Utility. When you create your logical drive using the Wizard Advanced option or you create a logical drive manually, you can choose a sector size of 512 B, 1 KB, 2 KB, or 4 KB.
Page 240: Formatting Logical Drives
Promise Technology Pegasus32 R4/R6/R8 Formatting Logical Drives A RAID logical drive must also be formatted to be compatible with your computer. In this Product Manual, the term format includes both partition and format operations. You can format your logical drives using the: • Pegasus Utility with default settings (below)
Page 241 Pegasus32 Product Manual Technology Background Pegasus Utility with Custom Settings T o use your own format settings, you must create your logical drives using the Wizard Advanced option or create your logical drives manually, and you must UNcheck the Format box.

Page 243: Spare Drives
Pegasus32 Product Manual Technology Background Spare Drives Spare drive technology includes: • Definition (page 92) • Options (page 92) • Requirements (page 92) • Transition (page 93) Definition A spare drive is a physical drive that you designate to automatically replace the failed physical drive in a disk array.
Page 244: Equirements
Promise Technology Pegasus32 R4/R6/R8 Requirements The spare drive must: • Have adequate capacity to replace the largest physical drive in your disk arrays. • Be the same media type as the physical drives in your disk arrays. A revertible spare drive requires: •...
Page 245 Pegasus32 Product Manual Technology Background Transition happens manually when you specify a different unconfigured physical drive to transition (move) the data from the revertible spare drive. See the example on the following pages. 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. Physical drive 6 is a revertible spare drive.
Page 246 Promise Technology Pegasus32 R4/R6/R8 When the rebuild is complete, the spare drive has replaced the failed drive. In this example, failed drive 3 was replaced by spare drive 6. The disk array now consists of physical drives 1, 2, 4, and 6.
Page 247 Pegasus32 Product Manual Technology Background Returns drive 6 to spare status When the Automatic Transition is finished, physical drives 1, 2, 3, and 4 belong to the disk array and physical drive 6 is a revertible spare drive. The original configuration is restored. Manual Transition If you wanted to use the drive in slot 5 as a member of the disk array, rather than the drive in slot 3, you would run the Transition function manually.
Page 248: Raid Controllers
Promise Technology Pegasus32 R4/R6/R8 RAID Controllers RAID controller technology includes: • Cache Policy (“Read Cache Policy” and “Write Cache Policy”) • “Capacity Coercion” As it is used with Pegasus, 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.
Page 249: Apacity C Oercion
Pegasus32 Product Manual Technology Background Capacity Coercion This feature is designed for fault-tolerant logical drives (RAID 1, 1E, 5, 6, and 10). It is generally recommended to use physical drives of the same size in your disk arrays. When this is not possible, the system adjusts for the size differences by reducing or coercing the capacity of the larger drives to match the smaller ones.
