Chapter 7: Technology Background • Introduction to RAID (below) • Choosing a RAID Level (page 196) • Choosing Stripe Block Size (page 199) • Gigabyte Boundary (page 199) • Initialization (page 199) • Hot Spare Drive (page 200) • Partition and Format Logical Drive (page 200) • Cache Settings (page 201) • RAID Level Migration (page 201) Introduction to RAID RAID (Redundant Array of Independent Disks) allows multiple hard drives to be combined together to form one large logical drive.
VTrak 15200 User Manual RAID 0 – Striping When a disk 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 7: Technology Background RAID 1 – Mirroring 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.
VTrak 15200 User Manual RAID 3 – Block Striping with Dedicated Parity RAID level 3 organizes data across the disk drives of the logical drive, and stores parity information on to a disk drive dedicated to this purpose. This organization allows increased performance by accessing multiple disk drives simultaneously for each operation, as well as fault tolerance by providing parity data.
Chapter 7: Technology Background RAID 5 – Block Striping with Distributed Parity RAID 5 is similar to RAID 3 as described above except that the parity data is distributed across the disk drives along with the data blocks. In each case, the parity data is stored on a different disk than its corresponding data block. RAID 5 makes efficient use of hard drives and is the most versatile RAID Level. It works well for file, database, application and web servers.
VTrak 15200 User Manual RAID 10 – Mirroring / Striping Mirroring/Striping 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 5.
Chapter 7: Technology Background RAID 50 – Striping of Distributed Parity Logical Drives 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. RAID 50 also provides high reliability because data is still available even if two disk drives fail (one in each data stripe). Distributed Parity Data Stripe Disk Drives Figure 6.
VTrak 15200 User Manual Choosing a RAID Level There are several issues to consider when choosing the RAID Level for your VTrak logical drive. The following discussion summarizes some advantages, disadvantages and applications for each choice.
Chapter 7: Technology Background RAID 3 Advantages Disadvantages High Read data transfer rate Disk failure has an insignificant impact on throughput Parity drive can become bottleneck if a lot of data is being written to the logical drive Recommended Applications for RAID 3 • Image Editing • Prepress Applications • Any application requiring high throughput RAID 5 Advantages Disadvantages High Read data transaction rate Disk failure has a medium impact on throughput Medium Write data transacti
VTrak 15200 User Manual 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 198
Chapter 7: Technology Background Choosing Stripe Block Size The stripe block size value can be set to 4KB, 8KB, 16KB, 32KB, and 64KB. 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.
VTrak 15200 User Manual 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. VTrak will replace a failing disk drive in a logical drive with an unassigned drive, if one is available.
Chapter 7: Technology Background Cache Settings There is a data cache on the VTrak controller and another one on each Physical disk drive. A cache holds data in volatile memory during RAID management and data transfer activity. The right combination of cache settings for your needs can improve VTrak’s efficiency and performance. Physical Drive Write Cache – Activates the write cache on the disk drive. Write Back Cache – Activates write-back feature of VTrak’s controller cache.
VTrak 15200 User Manual Different types of logical drives use different organizational models and have varying benefits. The following outline breaks down the properties for each type of RAID supported by Promise products.

Chapter 8: Troubleshooting Critical & Offline Logical Drives A fault-tolerant logical drive—RAID 1, 3, 5, 10 and 50—goes critical when a drive is removed or fails. Due to the fault tolerance of the logical drive, the data is still available and online. However, once the logical drive goes critical, the logical drive has lost its fault tolerance, and performance may be adversely affected.
VTrak 15200 User Manual With a Hot Spare Drive If the logical drive rebuilds itself using the hot spare: 1. Replace the failed drive. 2. Check the automatic rebuild and hot spare policy to be sure your logical drive(s) recognize(s) the new drive as a hot spare. Without a Hot Spare Drive If no hot spare drive is available, the VTrak will not rebuild the logical drive and it will remain Critical.
Chapter 8: Troubleshooting 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 15200 User 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 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 in order to become aware of the condition.

Chapter 9: Support Why can a RAID 1 logical drive on VTrak consist of only two disk drives? On VTrak, RAID 1 logical drives work in matched pairs. But you are not limited to just one RAID 1 logical drive. VTrak supports up to 7 RAID 1 logical drives, using up to 14 disk drives. See page 189 for more information on the number of disk drives you can use for each RAID level. Are logical drives on VTrak limited to 2.199 terabytes? No. The 2.199 TB logical drive size limit does not apply to VTrak.
VTrak 15200 User Manual How can I be sure everything is working OK on the VTrak? VTrak has several 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. What happens if a logical drive goes critical? On the front of VTrak, the logical drive LED turns amber and an audible alarm sounds. This condition is described in Chapter 4 of the VTrak User Manual on the Software CD.
