VTrak M310p, M210p Product Manual RAID 0 – Stripe When a disk array is striped, the read and write blocks of data are interleaved between the sectors of multiple drives. Performance is increased, since the workload is balanced between drives or “members” that form the disk array. Identical disk drives are recommended for performance as well as data storage efficiency. The disk array’s data capacity is equal to the number of disk drive members multiplied by the smallest drive's capacity.
Chapter 7: Technology Background RAID 1 – Mirror When a disk array is mirrored, identical data is written to a pair of 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 drive fails or has errors, the other mirrored drive continues to function.
VTrak M310p, M210p Product Manual RAID 1E – Enhanced Mirror RAID 1E offers the security of mirrored data provided by RAID 1 plus the added capacity of more than two disk drives. It also offers overall increased read/write performance plus the flexibility of using an odd number of disk drives. With RAID 1E, each data stripe is mirrored onto two disk drives. If one drive fails or has errors, the other drives continue to function, providing fault tolerance.
Chapter 7: Technology Background RAID 5 – Block and Parity Stripe RAID 5 organizes block data and parity data across the physical drives. Generally, RAID Level 5 tends to exhibit lower random write performance due to the heavy workload of parity recalculation for each I/O. RAID 5 is generally considered to be the most versatile RAID level Distributed Parity Data Blocks Disk Drives Figure 3.
VTrak M310p, M210p Product Manual RAID 6 – Block and Double Parity Stripe RAID level 6 stores dual parity data is rotated across the physical drives along with the block data. A RAID 6 disk logical drive can continue to accept I/O requests when any two physical drives fail. Double Distributed (P and Q) Parity Data Blocks physical drives The total capacity of a RAID 6 disk logical drive is the smallest physical drive times the number of physical drives, minus two.
Chapter 7: Technology Background RAID 10 – Mirror + Stripe Mirroring/striping combines both of the previous RAID 1 and RAID 0 disk array types. RAID 10 is similar though not identical to RAID 0+1. RAID 10 can increase performance by reading and writing data in parallel while protecting data with duplication. At least four drives are needed for RAID 10 to be installed. With four disk drives, the drive pairs are striped together with one pair mirroring the first pair.
VTrak M310p, M210p Product Manual RAID 50 – Striping of Distributed Parity RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across disks 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. Distributed Parity Axle 1 Data Stripes Axle 2 Disk Drives Figure 5.
Chapter 7: Technology Background attempts to distribute the number of disk drives equally among the axles but in some cases, one axle will have more disk drives than another. No. of Drives in RAID 50 Array No. of Axles in RAID 50 Array No.
VTrak M310p, M210p Product Manual Choosing a RAID Level There are several issues to consider when choosing the RAID Level for your VTrak disk array. The following discussion summarizes some advantages, disadvantages, and applications for each choice.
Chapter 7: Technology Background RAID 1E Advantages Disadvantages Implemented as a mirrored disk array whose segments are RAID 0 disk arrays Very high disk overhead - uses only 50% of total capacity High I/O rates are achieved thanks to multiple stripe segments Can use an odd number of disks Recommended Applications for RAID 1E: • Imaging applications • Database servers • General fileserver RAID 5 Advantages Disadvantages High Read data transaction rate Disk failure has a medium impact on thro
VTrak M310p, M210p Product Manual RAID 10 Advantages Disadvantages Implemented as a mirrored disk array whose segments are RAID 0 disk arrays Very high disk overhead - uses only 50% of total capacity High I/O rates are achieved thanks to multiple stripe segments Recommended Applications for RAID 10: • Imaging applications • Database servers • General fileserver RAID 50 Advantages Disadvantages High Read data transaction rate Higher disk overhead than RAID 5 Medium Write data transaction rate
Chapter 7: Technology Background 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 disk array. In order to change the Stripe Size of an existing disk array, you must delete the disk array and create a new one. You can select Stripe Size directly when you use the Advanced function to create a disk array.
VTrak M310p, M210p Product Manual To make use of logical drives greater than 2TB in size, a larger sector size is required. The table below correlates sector size with logical drive capacity. Logical Drive Size Sector Size 8 to 16 TB 4096 bytes (4 KB) 4 to 8 TB 2048 bytes (2 KB) 2 to 4 TB 1024 bytes (1 KB) 0 to 2 TB 512 bytes (512 B) When you create a Disk Array using the Express or Advanced methods, and when you create a Logical Drive, you can specify sector size of 512 B; 1, 2, or 4 KB.
Chapter 7: Technology Background • Read Ahead – The read cache and the read-ahead feature are enabled. Read-ahead anticipates the next read and performs it before the request is made. Can increase read performance. • No Cache – The read cache is disabled. Write Cache Policy • Write Back – Data is written first to the cache, then to the physical drive. Better performance. VTrak has a cache backup battery to protect data in the cache from a sudden power failure. • Write Thru – Also “Write Through”.
VTrak M310p, M210p Product Manual Capacity Coercion also affects a replacement drive used in a disk array. Normally, when an physical drive fails, the replacement drive must be the same capacity or larger. However, the Capacity Coercion feature permits the installation of a replacement drive that is slightly smaller (within 1 gigabyte) than the remaining working drive. For example, the remaining working drives can be 80.5GB and the replacement drive can be 80.3, since all are rounded down to 80GB.
Chapter 7: Technology Background The spare drive effectively takes the place of the failed drive and the RAID system immediately begins to rebuild data onto the drive. When the rebuild is complete, the disk array is returned to fault tolerant status. VTrak 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 200.

Chapter 7: Technology Background Important • The Target disk array may require more disk drives than the Source disk array • If the Target disk array requires an EVEN number of disk drives but the Source disk array has an ODD number, ADD a disk drive as part of the migration process • You cannot reduce the number of disk drives in your disk array, even if the Target disk array requires fewer disk drives than the Source disk array • RAID 1 (mirroring) works with two drives only.
VTrak M310p, M210p Product Manual Current LD Size Maximum LD Expansion Size Sector Size 8 to 16 TB 16 TB 4096 bytes 4 to 8 TB 8 TB 2048 bytes 2 to 4 TB 4 TB 1024 bytes 0 to 2 TB 2 TB 512 bytes You can direct WebPAM to expand a logical drive beyond the maximum expansion size. When the expansion is finished, WebPAM will show the logical drive in the desired size.
Chapter 7: Technology Background Predictive Data Migration (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.
VTrak M310p, M210p Product Manual Transition The Transition feature enables you to specify “permanent” spare drives for your VTrak 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 nonrevertible spare. The revertible spare drive returns to its original status. Transition happens automatically when the following sequence of events takes place: • You create a revertible spare drive.
Chapter 7: Technology Background 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. If a physical drive fails in a disk array and there is a spare drive of adequate capacity available, the controller automatically rebuilds the array using the spare drive.
VTrak M310p, M210p Product Manual Automatic Transition At this juncture, you would replace the failed drive in slot 3 with a new one of the same or greater capacity. When the VTrak controller detects the new drive in slot 3, it will: • Automatically transition the data on drive 6 to drive 3 • Return 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.

VTrak M310, M210p Product Manual Critical & Offline Disk Arrays A fault-tolerant disk array—RAID 1, 1E, 5, 6, 10, and 50—goes critical when a disk drive is removed or fails. Due to the fault tolerance of the disk array, the data is still available and online. However, once the disk array goes critical, the disk array has lost its fault tolerance, and performance may be adversely affected.
Chapter 8: Troubleshooting To set up a spare drive, see “Create Spare Drive” on page 113 (WebPAM PROe) or “Create New Spare Drive” on page 155 (CLU). Without a Hot Spare Drive If there is no hot spare drive of adequate capacity, you must remove the failed drive and install an unconfigured replacement drive of the same or greater capacity in the same slot as the failed drive. Until you install the replacement drive, the logical drive will remain Degraded.
VTrak M310, M210p Product Manual • The drive carrier holding the rebuilding physical drive displays a green Activity (left) LED while the Status (right) LED flashes green once per second. During rebuilding, you can still read and write data to the logical drive. However, fault tolerance is lost until the Disk Array returns to OK (not-rebuilding) status.
Chapter 8: Troubleshooting Enclosure Problems WebPAM PROe displays yellow !s components that need attention. red Xs in Tree View to identify When a yellow ! appears over a Subsystem in Tree View, click on the Enclosure icon. The Enclosure screen will display (below). In this example, a power supply has failed. The Enclosure Diagram displays color and motion changes to identify the failed power supply. In this case, you must replace the power supply.
VTrak M310, M210p Product Manual Overheating Overheating is a potentially serious condition because the excessively high temperatures can lead to disk drive failure and controller malfunction. Overheating usually results from: • Fan failure • Poor air circulation around the enclosure WebPAM PROe reports failed fans along with elevated temperature.
Chapter 8: Troubleshooting Power Supplies VTraks are equipped with redundant power supplies. The advantage of dual power supplies is that, should one fail, the other will continue powering the subsystem until the faulty one can be replaced. VTrak is capable of operating on a single power supply. As a result, if one power supply fails you must watch the front panel LEDs or WebPAM PROe in order to become aware of the condition.
VTrak M310, M210p Product Manual Connection Problems When you install your Promise product following the instructions in the Quick Start Guide and this Product Manual, you should have little trouble getting your equipment to work the first time. But connection problems can arise that are not the User's or Installer's fault. Every conceivable problem cannot be covered in the documentation but some guidelines could be helpful. Connection problems cause a majority of failures in almost any electrical system.
Chapter 8: Troubleshooting CONSOLE SCSI “Out” connector Mgmt SCSI “Out” connector This means you can, for example, connect your Host PC to one of the VTrak’s SCSI “In” ports without the need of an external SCSI terminator. You can also connect both SCSI connectors in a “daisy-chain” with other VTraks. Be sure to enable termination on the last VTrak in the chain. Promise recommends that you attach the SCSI cable to the “In” connector and set the internal termination to “On” or “Automatic”.

Chapter 9: Support • Frequently Asked Questions (below) • Contact Technical Support (page 239) • Limited Warranty (page 242) • Returning product for repair (page 243) Frequently Asked Questions What kind of disk drives can I use with VTrak? VTrak supports 1.5 and 3.0 GB/s Serial ATA disk drives. Can I take the disk drives from my UltraTrak, put them into the VTrak and keep my disk array or logical drive intact? Yes.
VTrak M310, M210p Product Manual My WebPAM connection was working OK. But later on, it timed out. What do I do now? The network condition can time-out for several reasons. When an open connection has no action for a specific amount of time (the Administrator can change it), the connection times-out automatically for security reasons. When you attempt to use WebPAM, it returns to the login screen. Enter your user name and password and click Login, and WebPAM will establish a new connection.
Chapter 9: Support How can I be sure everything is working OK on the VTrak? Locally: The VTrak enclosure has LEDs on the front to monitor the status of power, field replaceable units (FRUs) and logical drives. When these are green, VTrak is functioning normally. Remotely: Check the Tree Icons in WebPAM. If there are no yellow or red warning icons displayed, VTrak is functioning normally.
