Chapter 7: Technology Background This chapter covers the following topics: • Disk Arrays (below) • Logical Drives (page 333) • Spare Drives (page 355) • RAID Controllers (page 361) • iSCSI Management (page 366) • Internet Protocols (page 373) Disk Arrays Disk array technology includes: • Media Patrol (page 331) • PDM (page 331) • Power Management (page 332) Media Patrol Media Patrol is a routine maintenance procedure that checks the magnetic media on each disk drive.
VTrak E-Class Product Manual PDM constantly monitors your physical drives and automatically copies your data to a spare drive before the physical drive fails and your logical drive goes Critical. The following actions trigger PDM: • A phyical drive with unhealthy status (see below) • Media Patrol finds a critical error • You initiate PDM manually PDM also counts the number of media errors reported by Media Patrol.
Chapter 7: Technology Background Logical Drives Logical drive technology includes: • RAID Levels (page 333) • RAID Level Migration (page 347) • Stripe Size (page 353) • Sector Size (page 353) • Preferred Controller ID (page 353) • Initialization (page 354) • Partition and Format (page 354) 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.
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 336
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 341 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 The chart below shows RAID 50 logical drives with 6 to 32 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle. RAID 50 Logical Drive No. of Drives No. of Axles Drives per Axle No. of Drives No.
VTrak E-Class Product Manual Recommended Applications for RAID 50: • File and Application servers • Transaction processing • Office application with many users accessing small files 344
Chapter 7: Technology Background RAID 60 – Striping of Double Parity RAID 60 combines both RAID 6 and RAID 0 features. Data is striped across disks as in RAID 0, and it uses double distributed parity as in RAID 6. RAID 60 provides data reliability, good overall performance and supports larger volume sizes. Figure 8.

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.
VTrak E-Class Product Manual RAID 5 A RAID 5 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. RAID 5 Add physical drives. 32 maximum. RAID 6 4 physical drives minimum, 32 maximum. 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. If existing physical drives have no unused space, add 1 or more physical drives.

RAID 5 3 physical drives minimum, 32 maximum. RAID 10 must have less than 16 physical drives. RAID 6 4 physical drives minimum, 32 maximum. RAID 10 must have less than 32 physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 Add physical drives. Even number of physical drives.
VTrak E-Class Product Manual RAID 50 A RAID 50 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. 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 167 or page 245.
Chapter 7: Technology Background Spare Drives Spare drive technology includes: • Definition (page 355) • Options (page 355) • Requirements (page 355) • Transition (page 356) 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 173.
VTrak E-Class Product Manual A revertible spare drive requires: • You to replace the failed physical drive in the disk array • You to run the Transition function 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.
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 RAID controller technology includes; • LUN Affinity (page 361) • ALUA (page 361) • Cache Policy (page 362) • Preferred Controller ID (page 364) • Power Saving (page 364) • Capacity Coercion (page 364) LUN Affinity VTrak subsystems with dual RAID 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.
VTrak E-Class Product Manual Cache Policy As it is used with VTrak, the term cache refers to any of several kinds of highspeed, 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. There are read caches, which hold data as it is read from a physical drive; and write caches, which hold data as it is written to a physical drive.
Chapter 7: Technology Background The Forced Read-Ahead cache policy setting provides predictive pre-fetching of data requests, allowing the controller to aggressively buffer large chunks of data in cache memory to prevent frame drops on high-bandwidth video playback. Not normally enabled for non-video applications. Adaptive Writeback Cache On the VTrak subsystem, you can set the logical drive write cache policy to Write Thru or Write Back.
VTrak E-Class Product Manual Preferred Controller ID See “Preferred Controller ID” on page 353. 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: • Park the read/write heads – Referred to as Power Saving Idle Time on VTrak. • Reduce disk rotation speed – Referred to as Power Saving Standby Time on VTrak.
Chapter 7: Technology Background 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.
VTrak E-Class Product Manual iSCSI Management iSCSI management uses the following terms: • Basic iSCSI (page 366) • iSCSI on a VLAN (page 368) • Initiator (page 369) • Target (page 370) • Portal (page 371) • Port (page 371) • Trunk (page 372) • Session (page 372) • iSNS (page 372) • CHAP (page 372) • Ping (page 373) Also see “Managing iSCSI Connections” on page 188 or page 257.

VTrak E-Class Product Manual iSCSI on a VLAN VTrak supports up to 32 iSCSI portals per iSCSI port. Each iSCSI portal can belong to a different VLAN for a maximum of 32 VLANs. See the diagram on page 335, Figure 2. To set up the VTrak subsystem for a VLAN: 1. Add a new portal with a VLAN association. See “Adding iSCSI Portals” on page 194 or page 264. Note which iSCSI port you chose for the portal. 2. Add a new target. See “Adding iSCSI Targets” on page 190 or page 259. 3.

VTrak E-Class Product Manual Each initiator has a unique iSCSI qualified name (IQN). You specify the initiator by that name when you map a LUN or logical drive to the initiator. Initiators come in two varieties, software and hardware. Software A software initiator uses code to implement iSCSI. The software emulates SCSI devices for a computer by speaking the iSCSI protocol.
Chapter 7: Technology Background CHAPs Challenge Handshake Authentication Protocol (CHAP) is an authentication mechanism used to authenticate iSCSI sessions between initiators and targets. A uni-directional or peer CHAP authenticates from the target (VTrak) to the initiator (host PC or server). A bi-directional or local CHAP authenticates target to initiator and initiator to target. Portal A portal is the logical point of connection between the VTrak and the iSCSI network.
VTrak E-Class Product Manual Trunk A trunk is an aggregation of two or more iSCSI ports on the same RAID controller. Also known as a link aggregation. This feature combines ports to increase bandwidth. Ports must be enabled to add them to a trunk. Trunks are identified by their Trunk IDs. When you create a trunk, you specify: • Controller ID – RAID controller whose iSCSI ports you are using. • Master port – Any available iSCSI port. • Slave ports – The remaining available iSCSI ports.
Chapter 7: Technology Background A uni-directional or peer CHAP authenticates from the target (VTrak) to the initiator (host PC or server). A bi-directional or local CHAP authenticates target to initiator and initiator to target. Ping Ping is a computer network administration utility that tests whether a device is accessable over the IP network. Ping sends echo request packets to the target node, such as your host PC or server, and waits for a response.

Appendix C: Multipathing on Linux The appendix covers the following topics: • Before You Begin (below) • Task 1: Meeting Package Requirements (page 473) • Task 2: Preparing the Configuration File (page 476) • Task 3: Making Initial Host Settings (page 478) • Task 4: Create and Configure Devices (page 480) • Task 5: Setting-up ALUA (page 481) • RPM Packages and Documents for Linux MPIO (page 486) • Linux MPIO: Known Issues (page 488) • Sample multipath.
VTrak E-Class Product Manual Check Initial Setup To check your initial setup, verify that you can view the logical drives on your VTrak from your Linux desktop or terminal window. Refer to the Linux Administration Manual for the procedure on your system. • If you can see your logical drives, the system is properly configured. Go to “Task 1: Meeting Package Requirements” on page 473. • If you cannot see your logical drives, make the necessary adjustments and check again.
Task 1: Meeting Package Requirements Task 1: Meeting Package Requirements The latest device mapper and multipath packages must be loaded onto your Linux host before configuring Device Mapper Multipath (DM-MP). When this document was written, the current versions were: • • • • • • • For RHEL 5.3 • device-mapper-1.02.28-2.el5 • device-mapper-multipath-0.4.7-23.el5 For RHEL 5.4 • device-mapper-1.02.32-1.el5 • device-mapper-multipath-0.4.7-30.el5 For RHEL 5.5 • device-mapper-1.02.39-1.
VTrak E-Class Product Manual 2. Type the following command and press Enter: # rpm -ivh device-mapper-multipath-0.4.7-8.el5.i386.rpm The system returns the following lines: Preparing... ##################### [100%] 1:device-mapper-multipath##################### [100%] # (or a similar message) Important Where possible, obtain the device mapper and multipath tool from the original installation CDs to ensure full compatibility with your existing OS. Refer to your OS documentation for more information.
Task 1: Meeting Package Requirements 2. Type the following command and press Enter: # rpm -qa | grep device-mapper If the required package is present, the system returns the following line.
