Introduction I2O Support (HP NetRAID-3Si Adapters Only) HP NetRAID-3Si adapters support I2O (Intelligent Input/Output) with some operating systems. For a complete list of operating systems for which HP NetRAID I2O drivers are available, see the HP web site at www.hp.com/go/netserver Physical Disk - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 17
will help you install your HP NetRAID, HP NetRAID-1, or HP NetRAID-3Si adapter, and plan the configuration. It guides you through power-up, launching the HP NetServer Navigator software, making the initial configuration of the adapter, and installing a NOS-specific configuration utility. It contains - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 18
instructs you to install additional I/O cards and to configure the mass storage subsystem. Other Information Sources Disk array administration and management are beyond the scope of this document. Refer to the HP NetRAID Series User Guide in Information Assistant on the HP NetServer Navigator - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 19
Chapter 1 Introduction CAUTION All HP NetRAID adapter cards are sensitive to static electricity and can easily be damaged by improper handling. Using a grounding strap is recommended. Read the following information carefully - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 20

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 - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 22
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. When a disk fails, the HP NetRAID adapter's firmware can automatically rebuild the data from the failed disk onto the hot spare. The system administrator - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 23
level has different advantages in terms of performance, redundancy, and capacity. HP NetRAID Series adapters support both nonspanned array and spanned array configurations. • Non-spanned arrays have logical drives that are contained entirely within the array. Non-spanned array configurations use - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 24
disk space is allocated for redundancy. Access time is fast for both reads and writes. RAID 0 Disadvantages RAID 0 provides no redundancy so if a hard drive fails, data must be restored from backup. Hot spares cannot be used with RAID 0 configurations. RAID 0 Summary Choose RAID 0 if redundancy is - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 25
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. Data is written as follows: Stripe 1 Stripe - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 26
due to disk failure, because if one disk fails, data can be rebuilt. Only one disk in the RAID 3 logical drive is reserved to provide redundancy. HP NetRAID Series firmware optimizes RAID 3 data flow for long, serial data transfers such as video or imaging applications. RAID 3 Disadvantages - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 27
random. For example, to change Block 1 in the diagram above, the HP NetRAID Series adapter must first read Blocks 2, 3, and 4 before it can calculate be rebuilt. Capacity equivalent to only one disk in the RAID 5 logical drive is reserved to store redundant data. RAID 5 outperforms RAID 1 for read - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 28
array: each array can have two disks, three disks, four disks, and so on. NOTE With HP NetRAID-1, a single logical drive can span only two arrays and supports a maximum of six to eight physical drives. RAID 10: Spanning with Mirrored Arrays A RAID 10 configuration uses two, three, or four pairs - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 29
disk failure, because if one disk fails, data can be rebuilt. Only one disk in each array of a RAID 30 logical drive is required to provide redundancy. HP NetRAID Series adapter firmware optimizes RAID 30 data flow for long, serial data transfers such as video or imaging applications. RAID 30 lets - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 30
offline operation only. Performance is slower than RAID 0 or RAID 10. RAID 50 Summary Choose RAID 50 if you need a large logical drive size, and cost, availability, and performance are equally important. RAID 50 performs best for I/O-intensive, high read/write ratio applications such as transaction - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 31

guides you through the planning process. • Step A, Plan Your Hardware, is the first step. • Step B, Plan Arrays and Logical Drives, is the second step. Worksheets are provided in Appendix C to help you record your choices.

channels can be assigned to the same array. HP NetRAID Series adapters support all HP hot swap SCSI devices and certain non-hot swap SCSI devices, such as the Wide hard disk drives installed in the HP NetServer E 45/50 and the HP NetServer LC II. As explained in Chapter 1, "Introduction," for - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 41
configurations permit you to create exactly the configuration that best suits your needs. Automatic Configuration Automatic mode defines the arrays and logical drives for you, and sets their parameters. It makes configuration easy. Automatic mode uses the following rules to define arrays: • It scans - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 42
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. When you create your arrays, you should look - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 43
levels reserve different amounts of capacity to provide redundancy. • A single array can be divided into a maximum of eight logical drives. • A single HP NetRAID Series adapter can control a maximum of eight logical drives. • If you want to use the online capacity expansion feature later on, logical - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 44
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.

Decide the - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 46
. However, if you want to use the online capacity expansion feature later on, plan to create just one logical drive per array. • Consider what RAID levels you need. Review the information in Chapter 2 and look at Tables 2-1 and 2-2 that compare the RAID levels. • Look at the arrays you have defined - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 47
can span both of these arrays. ◊ Spanned arrays must be numbered consecutively. ◊ When you use an HP NetRAID utility to configure your system, and you specify that a logical drive will span arrays, the system will span all eligible arrays that are numbered consecutively and that contain the same - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 48
the following information: • Array number to which the logical drive is assigned • Whether the logical drive spans up to four sequentially-numbered arrays • RAID level For each logical drive, you also need to define the logical drive size (capacity), stripe size, write policy, read policy, and - HP LH4r | Installation and configuration of the HP NetRAID, NetRAID-1 and NetRAI - Page 49
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.
