VTrak E-Class Product Manual • Each controller activity LED flashes green when there is activity on that controller. • The controller heartbeat LED blinks green once per second for five seconds, goes dark for ten seconds, then blinks green once per second for five seconds again. Steady means the LED is on. Blinking means a regular on/off pattern. Flashing means an intermittent and irregular on/off pattern. See the table below.
Chapter 3: Setup Drive Status Indicators The VTrak spins up the disk drives sequentially to equalize power draw during start-up. After a few moments: • The Power/Activity LED displays blue when a physical drive is present. • The Drive Status LED displays green when the physical drive is configured as a member of a disk array or as a spare. When the physical drive is unconfigured, the LED is dark. Steady means the LED is on. Blinking means a regular on/off pattern.
VTrak E-Class Product Manual Setting up the Management Ports Setting up the Management Ports consists of the following actions: • Setting up the Serial Connection (below) • Choosing DHCP or a Static IP Address (page 36) • VTrak Default IP Addresses (page 37) • Setting up VTrak with the CLI (page 37) • Setting up VTrak with the CLU (page 39) Setting up the Serial Connection VTrak has a Command Line Interface (CLI) to manage all of its functions, including customization.
Chapter 3: Setup If you choose to enable DHCP, have your Network Administrator dedicate an IP address for the VTrak, linked to the VTrak’s MAC address. This action prevents the DHCP server from assigning a new IP address when the VTrak restarts, with the result that users can no longer log in.

Chapter 7: Technology Background This chapter covers the following topics: • Disk Arrays (below) • Logical Drives (page 261) • Spare Drives (page 283) • RAID Controllers (page 289) Disk Arrays 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.
VTrak E-Class Product Manual • You initiate PDM manually PDM also counts the number of media errors reported by Media Patrol. 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 have a capacity of 512 reassigned blocks and 2048 error blocks.
Chapter 7: Technology Background Logical Drives 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. RAID 0 – Stripe When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple physical drives.
VTrak E-Class Product Manual Advantages • • • Disadvantages Implements a striped disk array, the data is broken down into blocks and each block is written to a separate disk drive I/O performance is greatly improved by spreading the I/O load across many channels and drives • Not a true RAID because it is not fault-tolerant • The failure of just one drive results in all data in an disk array being lost • Should not be used in mission critical environments No parity calculation overhead is involve
Chapter 7: 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.
VTrak E-Class Product Manual Advantages Disadvantages • • Simplest RAID storage subsystem design • 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 264
Chapter 7: Technology Background RAID 1E – Enhanced Mirror RAID 1E offers the security of mirrored data provided by RAID 1 plus the added capacity of more than two physical drives. It also offers overall increased read/ write performance plus the flexibility of using an odd number of physical drives. With RAID 1E, each data stripe is mirrored onto two physical drives. If one drive fails or has errors, the other drives continue to function, providing fault tolerance. Figure 3.
VTrak E-Class Product Manual 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. It works well for file, database, application and web servers. Figure 4.
Chapter 7: Technology Background 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 logical drive can continue to accept I/O requests when any two physical drives fail. Figure 5. RAID 6 stripes all drives with data and dual parity Data Blocks Double Distributed (Wide-space Q+Q) Parity Physical Drives Hence, a RAID 6 logical drive with (7) 100 GB physical drives has a capacity of 500 GB.
VTrak E-Class Product Manual RAID 10 – Mirror + Stripe Mirror + Stripe combines both of the RAID 1 and RAID 0 logical drive types. RAID 10 can increase performance by reading and writing data in parallel or striping, and duplicating the data, or mirroring. PROMISE implements RAID 10 by creating a data stripe over one pair of disk drives, then mirroring the stripe over a second pair of disk drives. Some applications refer to this method as RAID 0+1. Figure 6.
Chapter 7: Technology Background 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 • Recommended Applications for RAID 10: • Imaging applications • Database servers • General fileserver 269 Very high disk overhead – uses only 50% of total capacity
VTrak E-Class Product Manual RAID 50 – Striping of Distributed Parity RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across physical drives 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. Figure 7.

Chapter 7: 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 VTrak, 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.
VTrak E-Class Product Manual RAID 0 A RAID 0 source logical drive can migrate to the following target logical drives: Target Requirements RAID 0 Add physical drives. RAID 1 2 physical drives only. Only a single-drive RAID 0 can migrate to RAID 1 by adding 1 physical drive. RAID 1E 3 or more physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 5 3 physical drives minimum, 32 maximum. RAID 0 must have less than 16 physical drives.
Chapter 7: Technology Background RAID 1 A RAID 1 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E 3 or more physical drives. Add 1 or more physical drives. RAID 5 3 physical drives minimum, 32 maximum. RAID 1 must have less than 32 physical drives. Add 1 or more physical drives. RAID 10 4 physical drives minimum. Even number of physical drives. Add 2 or more physical drives. RAID 50 6 physical drives minimum, 32 per axle maximum.

RAID 5 32 physical drives maximum. RAID 50 must have less than 32 physical drives. RAID 6 32 physical drives maximum. RAID 50 must have less than 32 physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 Even number of physical drives. RAID 50 Add physical drives.
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 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.
VTrak E-Class Product Manual Initialization Initialization is done to logical drives after they are created from a disk array. Full initialization sets all data bits in the logical drive to a specified pattern, such as all zeros. The action is useful because there may be residual data on the logical drives left behind from earlier configurations. For this reason, Initialization is recommended for all new logical drives. See “Initializing a Logical Drive” on page 137 or page 197.
Chapter 7: Technology Background Spare Drives 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 142.
VTrak E-Class Product Manual Transition 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 non-revertible spare. The revertible spare drive returns to its original status. In order to run the Transition function, the spare drive must be revertible. In addition, you must specify an unconfigured physical drive of the same or larger capacity and same media type as the revertible spare drive.
Chapter 7: Technology Background Example Following is an example to explain the Transition function. 1 2 Array Drives 3 4 5 Spare Drive 6 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.
VTrak E-Class Product Manual drive. In this example, physical drive 3 failed and the array is rebuilt using physical drive 6, the revertible spare drive. 1 2 Array Drives 3 4 5 6 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.
Chapter 7: Technology Background 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 E-Class Product Manual 1 2 Array Drives 3 4 5 Spare Drive 6 When the Manual Transition is finished, physical drives 1, 2, 4, and 5 belong to the disk array and physical drive 6 is a revertible spare drive. At this point, you would replace the drive in slot 3. The new drive in slot 3 remains unconfigured until you assign it to a disk array or as a spare.
Chapter 7: Technology Background RAID Controllers LUN Affinity VTrak subsystems with two controllers include a LUN Affinity feature. Normally, either controller can access all logical drives. LUN Affinity enables you to specify which controller can access each logical drive. Use this feature to balance the load of your logical drives between the two controllers. To use LUN Affinity you must: • Have two controllers in the subsystem • Enable LUN Affinity under controller settings.
VTrak E-Class Product Manual • Write Thru – Also “Write Through.” Data is written to the cache and the logical drive at the same time. Safer.
Chapter 7: Technology Background Preferred Controller ID See “Preferred Controller ID” on page 281. Power Saving Power saving is a method of conserving energy by applying specific actions to hard disk drives (HDD). After an HDD has been idle for the set period of time, you can elect to: • Parking the read/write heads – Referred to as Power Saving Idle Time on VTrak. • Reducing disk rotation speed – Referred to as Power Saving Standby Time on VTrak.
VTrak E-Class Product Manual replacement drive that is slightly smaller (within 1 gigabyte) than the remaining working drive. For example, the remaining working drives can be 80.5 GB and the replacement drive can be 80.3, since all are rounded down to 80 GB. This permits the smaller drive to be used. Without capacity coercion, the controller does not permit the use of a replacement physical drive that is slightly smaller than the remaining working drives.

Overheating usually results from: • Fan failure • Inadequate air circulation around the enclosure Fan Failure In the Ex30 series VTrak subsystems, the power supply fans are the Cooling Units for the enclosure. When a power supply fan fails, you must replace the power supply.
Chapter 8: Troubleshooting Batteries The RAID controllers in the VTrak subsystem use a battery for backup power to protect data in the cache. Should a power failure occur, the battery enables the cache to hold data up to 72 hours. The battery recharges during normal subsystem operation. In most cases, installing a replacement battery corrects a marginal or failed condition. The battery is located inside the RAID controller housing.
