  • Page 21: Raid Overview, Physical Drive, Arrays

    2 RAID Overview This chapter summarizes concepts and terminology used to describe RAID systems. It describes the different RAID levels available with the HP NetRAID Series adapters. For definitions of terms not introduced here, see the Glossary. RAID Overview HP NetRAID Series adapters let you link multiple hard disk drives together and write data across them as if they were one large drive.

  • Page 22: Hot Spare, Logical Drive

    Chapter 2 RAID Overview Arrays can combine disk drives that are all on one channel, or they can combine disk drives from two or three different channels. Hot Spare A hot spare is a powered-on, stand-by disk drive that is ready for use should another disk drive fail.

  • Page 23: Understanding Raid Levels

    Chapter 2 RAID Overview Figure 2-3. Sample Configuration with Three Arrays and Three Logical Drives Understanding RAID Levels During installation, you configure your logical drives by running a disk array configuration utility. Each of the logical drives you define must have an assigned RAID level.

  • Page 24: Arrays With No Redundancy: Raid Level 0

    Chapter 2 RAID Overview Arrays with No Redundancy: RAID Level 0 RAID 0: Striping In RAID 0 configurations, data is distributed among hard disks in the array via an algorithm called striping. Data written to a logical drive is divided into pieces called blocks.

  • Page 25: Non-spanned Arrays With Redundancy: Raid Levels 1, 3, And 5

    Chapter 2 RAID Overview Non-spanned Arrays with Redundancy: RAID Levels 1, 3, and 5 RAID 1: Mirroring In RAID 1 configurations, data on one disk is completely duplicated on another disk. This is called mirroring. RAID 1 must be configured on a two-disk array. (The array cannot contain more than two disk drives.) With this algorithm, if either of the two disks fail, data is available from the duplicate disk.

  • Page 26

    Chapter 2 RAID Overview RAID 3: Striping with Dedicated Parity In RAID 3 configurations, each data stripe generates one parity block to provide redundancy and data protection. The parity block is encoded information that can be used to reconstruct the data on that stripe if one of the disks fails. RAID 3 configurations dedicate one disk in the array to store all parity blocks.

  • Page 27

    Chapter 2 RAID Overview RAID 5: Striping with Distributed Parity RAID 5 is the most common configuration because it provides good overall performance and data protection with a minimum loss of storage capacity. RAID 5 distributes the parity blocks equally among all disk drives to achieve better overall performance than if a dedicated parity disk is used (RAID 3).

  • Page 28: Spanned Arrays: Raid Levels 10, 30, And 50

    Chapter 2 RAID Overview Spanned Arrays: RAID Levels 10, 30, and 50 With HP NetRAID and NetRAID-3Si adapters, array spanning allows the capacity of two, three, or four arrays to be combined into a single storage space. A spanned array configuration must have the same number of disk drives in each array: each array can have two disks, three disks, four disks, and so on.

  • Page 29

    Chapter 2 RAID Overview RAID 30: Spanning with Dedicated Parity Drives In RAID 30 configurations, parity blocks provide redundancy to a logical drive that spans two, three, or four arrays. (RAID 30 is a RAID 3 configuration with array spanning.) If your RAID 30 logical drive has two arrays with four physical drives each, data blocks are written as follows: Array 1 Array 2...

  • Page 39: Multiple Adapters, Slot Selection And Boot Order

    Chapter 4 Planning Multiple Adapters The disk array drivers and firmware will support up to six adapters, but your particular model of HP NetServer may have fewer PCI slots available. Be sure to check your system's PCI I/O slot availability and any slot restrictions before purchasing another adapter.

  • Page 40: Channels

    Chapter 4 Planning Log the adapter's PCI slot on Worksheet A. Channels In this section you determine which physical devices will connect to each SCSI channel of the adapter. Record the SCSI ID number and physical capacity of each disk drive in the correct channel on Worksheet A. No two devices on a single channel can have the same SCSI ID.

  • Page 41: Step B. Plan Arrays And Logical Drives, Automatic Configuration

    Chapter 4 Planning Step B. Plan Arrays and Logical Drives There are two ways to set up arrays and logical drives. Automatic configuration is explained for those users who do not want to customize their arrays and logical drives. Custom configurations permit you to create exactly the configuration that best suits your needs.

  • Page 42: Custom Configuration

    Chapter 4 Planning Custom Configuration To plan a custom configuration, you will do the following: Plan your arrays Plan hot spares Decide the rebuild rate Plan logical drives Plan Your Arrays In this section you specify which physical drives are assigned to which arrays. For each physical disk drive that is assigned to an array, log its array number in Worksheet A.

  • Page 43

    Chapter 4 Planning Consider what RAID levels you will need. Different RAID levels require different minimum numbers of physical drives. For example, RAID 1 requires exactly two physical drives, RAID levels 3 and 5 require at least three physical drives, and arrays with only one physical drive must be assigned RAID 0.

  • Page 44

    Chapter 4 Planning Figure 4-2. Three Logical Drives Where Each Array Uses a Different Channel Figure 4-3 shows the same configuration, except Array A1 contains physical drives from both Channel 0 and Channel 1, and Array 2 contains physical drives on Channels 1 and 2.

  • Page 45

    Chapter 4 Planning Plan Hot Spares (Optional) On Worksheet A for each adapter, log any hot spare disk modules and indicate whether each is global or dedicated to a particular array. A hot spare is a powered-on, stand-by disk that is ready for use should another disk fail.

  • Page 46

    Chapter 4 Planning Plan Logical Drives Logical drives are virtual drives configured within an array or across arrays. Logical drives can take three forms: A logical drive can use all of the storage capacity of one array. A logical drive can use less than the available storage capacity of one array.

  • Page 47

    Chapter 4 Planning Although each drive in an array must have the same capacity, one logical drive can span two or more arrays with different capacities. For example, one array might contain three drives of 4 MB each, and the second array might contain three drives of 12 MB each.

  • Page 49

    Chapter 4 Planning Logical Drive Size You can calculate the usable capacity to assign to each logical drive, or you can let the HP NetRAID Assistant Wizard specify it during configuration. If you calculate logical drive capacity, record it in Worksheet B. If you want a logical drive to occupy less space than is available on one array, you must enter the logical drive size.

    Chapter 4 Planning Write Back: In a write-back cache, data is written to disk only when it is forced out of the cache. Write-back is efficient, because an entry may be written many times in the cache without a disk access. Write Back can be used if an Uninterruptible Power Supply maintains the data in cache memory in the event of a power failure.

    Glossary logical drive in the array. You cannot use online capacity expansion on logical drives that span arrays (RAID levels 10, 30, or 50). Channel: An electrical path for the transfer of data and control information between a disk and a disk adapter. Format: The process of writing zeros to all data fields in a physical drive (hard drive) and to map out unreadable or bad sectors.

    Glossary pass a Consistency Check. Arrays work without initializing, but they may fail a Consistency Check because parity fields may not have been generated. Logical Drive: A virtual drive within an array, which may consist of more than one physical disk. Logical drives divide up the contiguous storage space of an array of disk modules or a spanned group of arrays of disks.

Physical Disk Roaming: The ability of an adapter to keep track of a hot swap disk module that has been moved to a different slot in the hot swap cages. Both slots must be controlled by the same adapter.

    Glossary RAID 5 has parity redundancy distributed over all the disks in the array. It requires three or more physical drives in an array. RAID levels 10, 30, and 50 result when logical drives span arrays. Table 2-2 in Chapter 2 describes RAID levels for logical drives that span arrays. RAID 10 results when a RAID 1 logical drive spans arrays.

    Glossary SCSI Disk Status: A SCSI disk module (physical drive) can be in one of five states: Ready: a powered-on and operational disk that has not been configured. Online: a powered-on and operational disk that has been configured. Hot Spare: a powered-on, stand-by disk ready for use should a disk fail. Not Responding: the disk is not present, not powered-on, or has failed.
