lets you link multiple hard disk drives together and write data across them as if they were one large drive. With the integrated HP NetRAID controller, you can configure your linked drives into a RAID (Redundant Array of Independent Disks) subsystem. Physical Drives The term "physical drive" refers - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 14
. Hot Spares 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 firmware can automatically rebuild the data from the failed disk onto the hot spare. The system administrator can then replace the failed disk and - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 15
an assigned RAID level. Each RAID level has different advantages in terms of performance, redundancy, and capacity. The integrated HP NetRAID controller supports both non-spanned array and spanned array configurations. • Non-spanned arrays have logical drives that are contained entirely within the - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 16
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. RAID 0 provides no data redundancy. - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 17
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 - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 18
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 firmware optimizes RAID 3 data flow for long, serial data transfers such as video or imaging applications. RAID 3 Disadvantages Performance is slower than - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 19
, may be slower than RAID 1, especially if most writes are small and random. For example, to change Block 1 in the diagram above, the integrated HP NetRAID controller must first read Blocks 2, 3, and 4 before it can calculate Parity Block 1-4. Once it has calculated the new Parity Block 1-4, it must - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 20
Chapter 2 RAID Overview Spanned Arrays: RAID Levels 10, 30, and 50 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 - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 21
, 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 firmware optimizes RAID 30 data flow for long, serial data transfers such as video or imaging applications. RAID 30 lets you create large logical - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 22
Chapter 2 RAID Overview RAID 50: Spanning with Distributed Parity In RAID 50 configurations, parity blocks are distributed throughout the logical drive that spans two, three, or four arrays. (RAID 50 is a RAID 5 configuration with array spanning.) If your RAID 50 logical drive has two arrays with - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 23

However, you can change the SCSI transfer Automatic mode uses the following rules to define arrays: • If integrated HP NetRAID is enabled for SCSI B, Automatic mode does not distinguish non- - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 34
drives, do not use Automatic mode. See "Custom Configuration," next in this guide, for recommendations on making best use of your non-hot-swap devices. If do the following: • Plan your non-hot-swap devices (only if integrated HP NetRAID is enabled for SCSI B) • Plan your arrays • Plan hot spares - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 35
Chapter 4 Planning Plan Your Non-Hot-Swap Devices If you plan to enable integrated HP NetRAID on SCSI B, you need to decide how to use the non-hot-swap SCSI devices. For each non-hot-swap device log its array - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 36
amounts of capacity to provide redundancy. • A single array can be divided into a maximum of eight logical drives. • The integrated HP NetRAID controller can support a maximum of eight logical drives. • If you want to use the online capacity expansion feature later on, logical drives cannot span - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 37

to a particular array. A hot spare is a powered-on, stand-by disk that is ready for use should another disk fail. When a disk fails, the HP NetRAID firmware can automatically rebuild the data from the failed disk onto the hot spare. Unless a rebuild occurs, a hot spare does not contain user data - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 39
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 - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 40
drives of 12 MB each. One logical drive 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 - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 41
in the sections that follow. 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 - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 42

disk modules into a single segment of contiguous storage space. The integrated HP NetRAID controller can group disk modules on one or more of its SCSI and 5 to RAID levels 10, 30, and 50, respectively. BIOS: (Basic Input/Output System) The part of the operating system of the computer that provides - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 130
is an industry-standard, I/O subsystem architecture independent of the network operating system and the peripheral devices supported. I2O uses drivers that are split into operating system services modules (OSMs) and hardware device modules (HDMs). I2O increases overall system performance by shifting - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 131
group of arrays of disks. The storage space in a logical drive is spread across all the disks in the array or spanned arrays. An integrated HP NetRAID controller can be configured with up to eight logical drives in any combination of sizes. Configure at least one logical drive for each array - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 132
Single Large Expensive Disk (SLED). A RAID disk subsystem improves I/O performance using only a single drive. The RAID array appears to the host HP NetServer as a single storage unit. I/O is expedited because several disks can be accessed simultaneously. RAID Levels: A style of redundancy applied to - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 133
RAID 5 logical drive spans arrays. Read Policy: The three Read policies for HP NetRAID are: • Read-Ahead: This is a memory caching ability that tells data in Fastand-Wide, Ultra SCSI, or Ultra2 SCSI mode. An integrated HP NetRAID controller can manage one or two SCSI channels. SCSI Disk Status: A - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 134
: errors on the disk have caused it to fail, or you have used an HP NetRAID utility to take the drive offline. • Rebuilding: a disk in the process of that the processor will probably read it again soon. The two Write policies for HP NetRAID are: • Write Back: In a write-back cache, data is written - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 135
Glossary memory read. Write-back is efficient, because an entry may be written many times in the cache without a disk access. • Write Through: In a write-through cache, data is written to disk at the same time as it is cached. Write-through is simpler than write-back, because an entry that is to be - HP D5970A | Integrated HP NetRaid Controller Configuration Guide - Page 136
