Page 95: A Raid Technology
RAID TECHNOLOGY RAID technology is used by your HP SureStore E Disk Array to utilize your disk space efficiently and to keep your data safe in case a problem occurs with one of your disk drives. RAID technology combines low cost and high performance, while providing you with high reliability.
Page 96: Using Raid0/1
Using RAID0/1 RAID0/1 uses both RAID0 and RAID1 technologies implemented together to achieve high reliability and high I/O performance on your disk array. RAID0 produces a striped drive volume. Striped data means that the stream of data from the host is split and distributed onto two or more of your disk devices on a byte or bit basis.
Page 97 2D + 2D Array Group Data Mirror Data Mirror LUN0 Mirror Data Mirror Data LUN1 LUNn RAID0/1 is a striped and mirrored copy within an ACP pair Figure 13. RAID0/1 Array Group RAID Technology...
Page 98: Understanding Raid3
Understanding RAID3 RAID3 is not supported on your XP disk array, but it is a preface to understanding RAID5, which is supported. RAID3 allows data to be split and distributed on two or more disk drives using striping. Because two or more disk drives are recording the data simultaneously, the transfer speed is faster.
Page 99: Using Raid5
Using RAID5 RAID5, like RAID3, processes data between two or more disk drives simultaneously. RAID5 also saves parity information to a separate disk drive. RAID5, unlike RAID3, saves information as blocks of data, which allows the RAID controller to access each disk for only one stripe of data. This also allows RAID5 to perform input/output operations on other disks in parallel.
Page 100 RAID5 requires four disks for an array group. RAID5 on the XP512 allows the data to be split and distributed onto three disk drives using striping. Parity data for the group is created and stored on the parity disk as in figure 16 (page 101).
Page 101 3D + 1P Array Group (1-3) (4-6) (7-9) (10-12) Figure 16. RAID5 with Parity Disk The downside to RAID0/1 over RAID5 is that there is a 100% overhead on storage redundancy associated with RAID0/1. RAID0/1 is often referred to as mirrored storage, because the user data is physically duplicated in the array.
Page 102 You will get more overall usable storage out of the array with a RAID5 implementation. RAID5 achieves the storage redundancy by generating parity data based on the data stored. RAID5 only requires a 33% storage overhead. Table 15. RAID Array Usage and Overhead RAID Type Disk Usage Overhead...
Page 103: Configuring Dynamic Spare Disks
Configuring Dynamic Spare Disks You can configure the disk array with a minimum of 1 and a maximum of 16 spare disk drives. For both RAID0/1 and RAID5 array groups, any dynamic spare drive can back up any other disk drive of the same capacity, anywhere in the disk array, even if the failed disk and the spare disk are on different array control processor (ACP) pairs.
