  • Page 14: Physical Disk Roaming And Data Migration

    Chapter 1 Introduction Enhanced Array Spanning The HP NetRAID-1M and 2M adapters allow up to eight arrays to be spanned together as one logical drive, although all the disks in the logical drive must be connected to the same adapter. The maximum number of disks connected to one adapter depends on the number of channels (one or two) and whether you are using the internal or external SCSI connectors.

    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- 1M and 2M adapters. For definitions of terms not introduced here, see the Glossary later in this guide. RAID Overview HP NetRAID-1M and 2M adapters let you link multiple hard disk drives together and write data across them as if they were one large drive.

  • Page 20: Hot Spares, Logical Drives

    Chapter 2 RAID Overview Arrays can combine disk drives that are all on one channel of an HP NetRAID-1M or 2M adapter, or they can combine disk drives from both channels of an HP NetRAID-2M adapter. However, all the disk drives in an array must be connected to a single NetRAID adapter.

  • Page 22: Arrays With No Redundancy: Raid Level 0

    Chapter 2 RAID Overview Spanned arrays have logical drives that are spread across multiple arrays (as many as eight). This permits the physical drives in up to eight arrays to function as one large logical drive. Each spanned array must contain the same number of disks and all the disks in the logical drive must be connected to the same NetRAID adapter.

  • Page 23: Basic Arrays With Redundancy: Raid Levels 1 And 5

    Chapter 2 RAID Overview Basic Arrays with Redundancy: RAID Levels 1 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 24

    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. If you have five physical drives configured as one RAID 5 logical drive, data blocks are written as follows: Disk 1...

  • Page 25: Spanned Arrays: Raid Levels 10 And 50

    Chapter 2 RAID Overview Spanned Arrays: RAID Levels 10 and 50 With HP NetRAID-1M and 2M adapters, array spanning allows the capacity of up to eight basic arrays to be combined into a single storage space. A spanned array configuration must have the same number of disk drives in each basic array.

  • Page 26

    Chapter 2 RAID Overview RAID 10 Disadvantages Costs are high, because 50% of all disk space is allocated for redundancy. Capacity expansion is an offline operation only. RAID 10 Summary RAID 10 provides the best performance for most applications where redundancy and large logical drive size are required, and cost is not a factor.

  • Page 27

    Chapter 2 RAID Overview With the HP NetRAID-2M adapter, you can span up to eight RAID 5 arrays, although the total number of disks in the RAID 50 logical drive is limited by the number of disks that can be attached to the two SCSI channels.

  • Page 33: Planning, Overview, Step A. Plan Your Hardware, Gather Information

    4 Planning Overview Before attempting to install and configure your disk array subsystem, you should invest some time in planning the configuration that best suits your computing environment. The options you choose depend on factors such as the host operating system used and your requirements for data protection, performance, and capacity.

  • Page 35: Multiple Adapters, Boot Order, Channels

    Chapter 4 Planning Multiple Adapters The HP NetRAID 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 36: Step B. Plan Arrays And Logical Drives, Automatic Configuration

    Chapter 4 Planning As explained in Chapter 1, "Introduction," for each channel, you have either one internal or one external connection. HP NetRAID-1M and 2M adapters support the following channels and connectors: The HP NetRAID-1M adapter provides an internal and external connector for Channel 0.

  • Page 37: Custom Configuration

    Chapter 4 Planning If a group contains three to five drives, and you checked Redundancy, the logical drive is assigned RAID level 5. If an array contains only one drive, the logical drive is assigned RAID level 0. (No redundancy is possible on a logical drive containing just one physical drive.) Automatic configuration does not create hot spares.

  • Page 38

    Chapter 4 Planning The physical drives in an array can be all on the same channel, or they can be on separate channels. You might plan to reserve one or more physical drives for use as a hot spare. See "Plan Hot Spares (Optional)" later in this chapter for more information.

    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 41

    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 42

    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.

    Chapter 4 Planning Write Policy When the IOP writes to disk, the data is first written to the cache on the assumption that the IOP will read it again soon. The two Write policies are: Write-Through: In a write-through cache, data is written to disk at the same time it is cached.

  • Page 46

    Chapter 4 Planning Read Policy The three Read policies for HP NetRAID are: Read-Ahead: This is a memory caching feature that tells the adapter to read sequentially ahead of requested data and cache the additional data in memory, anticipating that the additional data will be requested. Read-Ahead supplies sequential data faster, but it is not as efficient when accessing random data.
