VTrak M-Class 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 M-Class 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 M-Class Product Manual 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.
Chapter 7: Technology Background 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.
VTrak M-Class Product Manual 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.
Chapter 7: Technology Background 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.
VTrak M-Class Product Manual 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 throughpu
Chapter 7: Technology Background RAID 50 Advantages Disadvantages High Read data transaction rate Higher disk overhead than RAID 5 Medium Write data transaction rate Good aggregate transfer rate High reliability Supports large volume sizes Recommended Applications for RAID 50 • File and Application servers • Transaction processing • Office application with many users accessing small files 249
VTrak M-Class 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 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.
Chapter 7: Technology Background 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.
VTrak M-Class Product Manual • 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”.
Chapter 7: Technology Background 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.
VTrak M-Class Product Manual 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 258.

VTrak M-Class Product Manual Ranges of Disk Array Expansion There are limitations to how large you can expand a disk array, depending on the size of your current disk array. The current iSCSI, SCSI, and Fibre Channel HBA cards and PC Operating Systems support a 10-byte LBA format. This means that a disk array can have up to 4 billion address blocks or sectors.
Chapter 7: Technology Background 2. Delete the current logical drive. See page 137 (WebPAM PROe) or page 188 (CLU). 3. Create a new logical drive with the desired capacity. See page 135 (WebPAM PROe) or page 187 (CLU). 4. Restore the data to the new logical drive. 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. Media Patrol does not check unconfigured drives.
VTrak M-Class Product Manual A disk drive becomes unhealthy when: • A SMART error is reported • The bad sector remapping table fills to the specified level Because data would be lost if written to a bad sector, when a bad sector is detected, the disk drive creates a map around it. These maps are saved in the bad sector remapping table, which has a capacity of 512 reassigned blocks and 1024 error blocks.
Chapter 7: 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. 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 M-Class Product Manual 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 controller cannot use it as a spare. Automatic Transition At this juncture, you would replace the failed drive in slot 3 with a new one of the same or greater capacity.

VTrak M-Class Product Manual Critical & Offline Disk Arrays A fault-tolerant disk array—RAID 1, 1E, 5, 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 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. • If the Auto Rebuild function is ENABLED, the disk array will begin to rebuild automatically as soon as you replace the failed drive.

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 fan has stopped turning, indicating a failure. The Enclosure Diagram displays color and motion changes to identify a failed fan. In this case, you must replace the power supply.
VTrak M-Class 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 M-Class 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 SCSI “Out” connectors 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”.
VTrak M-Class Product Manual Network Connections VTrak has an RJ-45 Management Port connector on the back of its cabinet. This is a Gigabit Ethernet connector designed to connect to your network. The VTrak becomes a node on your network like any other PC, server or other component with an IP address. VTrak ships from the factory an IP address of 10.0.0.1. You must change this address to one that will work with your network. You make the initial IP address setting using the CLI or CLU.
Chapter 8: Troubleshooting Unsaved Data in the Controller Cache The VTrak M-Class controller has a 256 MB data memory cache protected by a battery backup. If there is a power failure while unsaved data is in the cache, the battery will power the cache and hold the data up to 72 hours. Dirty Cache LED (Fibre Channel) Dirty Cache LED (iSCSI) Dirty Cache LED (SCSI) An LED (marked with the icon) is provided to inform you that there is data in the cache that has not been saved to non-volatile memory.
