Pegasus2 R4/R6/R8 Product Manual Technology Background This chapter covers the following topics: • “Disk Arrays” • “Logical Drives” • “Formatting Logical Drives” • “Spare Drives” • “RAID Controllers” 88
Promise Technologies Disk Arrays Disk array technology includes: • Media Patrol • PDM 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. Media Patrol checks are enabled by default on all disk arrays and spare drives.
Pegasus2 R4/R6/R8 Product Manual 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.
Promise Technologies 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. Then all or a portion of the disk array is formed into a logical drive. The operating system sees the logical drive as a single storage device, and treats it as such.
Pegasus2 R4/R6/R8 Product Manual 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. If physical drives of different capacities are used, there is unused capacity on the larger drives. RAID 0 logical drives on Pegasus consist of one or more physical drives.
Promise Technologies 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. With RAID 1, if one physical drive fails or has errors, the other mirrored physical drive continues to function.
Pegasus2 R4/R6/R8 Product Manual Advantages Disadvantages • Simplest RAID level • • Can increase read performance by processing data requests in parallel since the same data resides on two different drives Very high disk overhead – uses only 50% of total capacity Recommended Applications for RAID 1: • Accounting • Payroll • Financial • Any application requiring very high availability RAID 1E – Enhanced Mirror RAID 1E offers the security of mirrored data provided by RAID 1 plus the adde
Promise Technologies Advantages Disadvantages • Implemented as a mirrored disk array whose segments are RAID 0 disk arrays • High I/O rates are achieved thanks to multiple stripe segments • Can use an odd number of disks • Very high disk overhead – uses only 50% of total capacity Recommended Applications for RAID 1E: • Imaging applications • Database servers • General fileserver RAID 5 – Block and Parity Stripe RAID 5 organizes block data and parity data across the physical drives.
Pegasus2 R4/R6/R8 Product Manual A RAID 5 on Pegasus R4 consists of three or four physical drives. A RAID 5 on Pegasus R6 consists of three to six physical drives.
Promise Technologies A RAID 6 on Pegasus R6 consists of four to six physical drives.
Pegasus2 R4/R6/R8 Product Manual The data capacity RAID 10 logical drive equals the capacity of the smallest physical drive times the number of physical drives, divided by two. In some cases, RAID 10 offers double fault tolerance, depending on which physical drives fail. RAID 10 arrays require an even number of physical drives and a minimum of four. For RAID 10 characteristics using an odd number of physical drives, choose RAID 1E.
Promise Technologies RAID 50 - Striping of Distributed Parity Advantages • High Read data transaction rate • Medium Write data transaction rate • Good aggregate transfer rate • High reliability • Supports large volume sizes Disadvantages • Higher disk overhead than RAID 5 (two drives as hot spares) Recommended Applications for RAID 50 include applications that require high fault tolerance and good I/O performance.
Pegasus2 R4/R6/R8 Product Manual 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. PROMISE implements RAID 60 by creating a data stripe across two RAID 6 sets. This creates very high fault tolerance, two drives in each RAID 6 set can fail without interrupting I/O or loss of data.
Promise Technologies 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. You can access the data while the migration is in progress. When migration is done, your disk array has a different RAID level and/or a larger capacity.
Pegasus2 R4/R6/R8 Product Manual RAID 1 A RAID 1 Source logical drive can migrate to the following Target logical drives: Target RAID 0 RAID 1E RAID 5 RAID 10 RAID 50 Requirements None. 3 or more physical drives. Add 1 or more physical drives. 3 physical drives minimum, maximum 4 (R4), 6 (R6) or 8 (R8). RAID 1 must have less than 4 (R4), 6 (R6) or 8 (R8) physical drives. Add 1 or more physical drives. 4 physical drives minimum. Even number of physical drives. Add 2 or more physical drives.
Promise Technologies RAID 1E A RAID 1E Source logical drive can migrate to the following Target logical drives: Target RAID 0 RAID 1E RAID 5 Requirements None. Add physical drives. 3 physical drives minimum, 4 (R4), 6 (R6) or 8 (R8). RAID 1E must have less than 4 (R4), 6 (R6) or 8 (R8) physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 4 physical drives minimum. Even number of physical drives.
Pegasus2 R4/R6/R8 Product Manual RAID 6 A RAID 6 Source logical drive can migrate to the following Target logical drives: Target RAID 6 RAID 60 Requirements Add physical drives. Maximum of 4 (R4), 6 (R6) or 8 (R8). 8 physical drives minimum. See “Migrating a Logical Drive” on page 79. RAID 10 A RAID 10 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None.
Promise Technologies RAID 50 A RAID 50 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None RAID 5 None RAID 6 None RAID 10 None RAID 1E None None RAID 60 See “Migrating a Logical Drive” on page 79. RAID 60 A RAID 60 Source logical drive can migrate to the following Target logical drives: Target RAID 6 Requirements None See “Migrating a Logical Drive” on page 79.
Pegasus2 R4/R6/R8 Product Manual 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.
Promise Technologies 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 PROMISE 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.
Pegasus2 R4/R6/R8 Product Manual 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: • PROMISE Utility with default settings (below) • PROMISE Utility with Custom Settings (page 90) • Disk Utility (page 91) Both the PROMISE Utility and the computer’s disk utility offer a choice of formatting options.
Promise Technologies PROMISE Utility with Custom Settings To 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. See “Creating a Disk Array and Logical Drive with the Wizard” on page 47 and “Creating a Logical Drive Manually” on page 61. To format your logical drives using the PROMISE Utility with your own settings: 1.
Pegasus2 R4/R6/R8 Product Manual Disk Utility For information on using your computer’s disk utility, see the online help or the computer’s User Manual. To format your logical drives using the computer’s disk utility, you must create your logical drives using the Wizard Advanced option or create your logical drives manually, and you must UNcheck the Format box. See “Creating a Disk Array and Logical Drive with the Wizard” on page 59 and “Creating a Logical Drive Manually” on page 74.
Promise Technologies 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. See “Creating a Spare Drive Manually” on page 69.
Pegasus2 R4/R6/R8 Product Manual 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.
Promise Technologies 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.
Pegasus2 R4/R6/R8 Product Manual 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. There is no spare drive at this moment. Even if physical drive 5 is of adequate capacity, it has not been designated as a spare, therefore the Pegasus controller cannot use it as a spare.
Promise Technologies 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. See “Running a Transition on a Spare Drive” on page 71.
Pegasus2 R4/R6/R8 Product Manual 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. Cache is important because it can read and write data much faster than a physical drive.
Promise Technologies 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. With Pegasus, you can choose to enable capacity coercion and any one of four methods.
Pegasus2 R4/R6/R8 Product Manual Troubleshooting This chapter deals problems you might encounter with your Pegasus unit and how to resolve them.
Promise Technologies Checking LEDs When you boot Pegasus unit, the Power Button LED turns orange. When fully booted, the LED turns blue. See page 102, Figure 1. See “Subsystem LEDs” on page 102. The drive carrier Power / Status LEDs turn blue if a physical drive is installed. See “Drive Carrier LEDs” on page 103. Subsystem LEDs The Pegasus subsystem LEDs are the Power Button and the Thunderbolt ports.
Pegasus2 R4/R6/R8 Product Manual Drive Carrier LEDs The Pegasus unit spins up the disk drives sequentially to equalize power draw during start-up. After a few moments: • The Power / Status LEDs turn blue. • The Activity LEDs turn blue if a drive is installed. The drive carrier Power / Status LEDs report the condition of the physical drives. See the table below.
Promise Technologies PROMISE Utility If you can open the PROMISE utility, but you cannot create or delete disk arrays and logical drives, nor can you make settings changes, check the UI lock.

Mounting screw Physical drive Mounting screw Mounting screw Mounting screw Drive carrier handle 4. Place the replacement drive into the carrier then install the four mounting screws. Tighten the screws just until they are snug. Position the drive carrier handle in outward position and slide the drive carrier back into the Pegasus unit. 5. Press the drive carrier handle inward until it locks.
Pegasus2 R4/R6/R8 Product Manual Physical Drive Warning Message If you see messages that says, “ajar HDD from the backplane,” you must reseat the physical drives. To reseat the physical drives: 1. On the Pegasus unit, press and hold the Power Button LED until it turns red. 2. Wait until the Power Button LED goes dark. 3. For each drive carrier, press the Release button, pull the drive carrier part way out of the unit, then press the drive carrier back in until it locks.
Promise Technologies Disk Array and Logical Drive Problems Disk array and logical drive troubleshooting includes: • “Disk Array Degraded / Logical Drive Critical” • “Disk Array Offline / Logical Drive Offline” • “Repairing an Offline Disk Array or Logical Drive” • “Rebuilding a Disk Array” • “Incomplete Array” • “Unreadable Disk Warning” Disk array problems typically result from a physical drive failure. The most common problem is a degraded disk array.
Pegasus2 R4/R6/R8 Product Manual Disk Array Offline/Logical Drive Offline Disk arrays are made up of physical drives. Logical drives are created on the disk array. When a disk array and its logical drives go Offline, the data stored in the logical drives is no longer accessible. RAID 0 logical drives go Offline when ONE physical drive is removed or fails. RAID 1, 1E, 5, and 10 logical drives go Offline when TWO physical drives are removed or fail.
Promise Technologies To recreate your logical drive: 1. Identify the failed physical drive. See “Locating a Physical Drive” on page 124. 2. Replace the failed drive. See ”Replacing a Physical Drive” on page 125. 3. If the disk array had more than one physical drive, delete the disk array and re-create it. See “Deleting a Disk Array” on page 67 and “Creating a Disk Array and Logical Drive with the Wizard” on page 59. 4. Restore the data from your backup source.
Pegasus2 R4/R6/R8 Product Manual Incomplete Array A more serious, but far less common problem is an Incomplete Array. An incomplete array results from a physical drive that fails or becomes missing during: • RAID level migration • Disk array transport Migration Normally, if a physical drive or the controller fails during migration, the disk array goes critical, and you can rebuild it.
Promise Technologies If you choose NOT to accept the incomplete array: 1. Click Cancel in the incomplete array dialog box. 2. Do one of the following: • • Delete the array. This action deletes all logical drives on the array. • • Replace the missing physical drive. Unreadable Disk Warning Your Pegasus logical drive displays on the computer’s desktop as a removable-drive icon (right).
Pegasus2 R4/R6/R8 Product Manual Subsystem Problems Subsystem problem troubleshooting includes: • “Diagnosing a Subsystem Problem” • “Overheating” • “Power Supply” Diagnosing a Subsystem Problem Check System Status on the Dashboard tab. If a yellow ! Status box: or red X 1. icon. Click the name link of the component with the red X appears in the System System Status box on the Dashboard The list containing the problem component displays.
Promise Technologies 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. The smaller fan cools power supply. Cooling fans are not field- replaceable.
Pegasus2 R4/R6/R8 Product Manual 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. • Ambient temperature above 35°C (95°F) where the unit is operating. To cool down a Pegasus unit: • Correct any problems identified above. • Shut down the Pegasus unit.
Promise Technologies Connection Problems Connection problem troubleshooting includes: • “Cables” • “Daisy-Chains” Cables While the installation of the cables and components was correct, they don't function properly, or at all, because: • A connector is dirty or corroded • A connector is loose or damaged • A cable looks OK outside but has an open circuit inside • The wrong cable was used. See the Note below Be sure to use approved cables because: • They are the proper ones for your system.
Pegasus2 R4/R6/R8 Product Manual Daisy-Chains If you have multiple Pegasus units daisy-chained together, all Pegasus units must be running to provide access to your volumes and the data they contain. If you shut down a Pegasus unit in the chain, that unit and those below it are effectively disconnected from your computer. Thunderbolt daisy-chain connections iMac used for this example, any Mac with a Thunderbolt port can be used.
Promise Technologies Performance Monitor The Performance Monitor display can be useful for diagnosing performance issues that will not necessarily trigger any alerts to appear in the System Status display or event logs. Or you can use it for testing performance of different drive types. To display the Performance Monitor information, choose Performance Monitor from the Admin dropdown menu in the Menu Bar. Note that it is necessary to unlock the interface before the option can be selected.
