5. RAID 10 A RAID 10 array is formed using a two layer hierarchy of RAID types At the lowest level of the hierarchy are a set of RAID 1 arrays i e mirrored sets These RAID 1 arrays in turn are then striped to form a RAID 0 array at the upper level of the hierarchy The collective result is a RAID 10 array The figure below demonstrates a RAID 10 comprised of two RAID 1 arrays at the lower level of the hierarchy arrays A and B These two arrays in turn are striped using 4 stripes comprised of the strips 1A 1B 2A 2B etc to form a RAID O at the upper level of the hierarchy The result is a RAID 10 Advantage RAID 10 ensures that if one of the disks in any parity group fails its contents can be extracted using the information on the remaining functioning disks in its parity group Thus it offers better data redundancy than the simple RAID types such as RAID 1 3 and 5 Also a RAID 10 array can improve the throughput of read operations by allowing reads to be performed concurrently on multiple disks in the set RAID 50 A RAID 50 array is formed using a two layer hierarchy of RAID types At the lowest level of the hierarchy is a set of RAID 5 arrays These RAID 5 arrays in turn are then striped to form a RAID 0 array at the upper level of the hierarchy The collective result is a RAID 50 array The figure below demonstrates a RAID 50 comprised of two RAID 5 arrays at the lower level of the hierarchy arrays X and Y These two arrays in turn

It is Intel s local bus standard that supports up to four plug in PCI cards per bus Since PCs can have two or more PCI buses the number of PCI cards they can support are a multiple of four The current PCI bus implementation version 2 2 incorporates two 64 bit slots at 66 MHz Consequently the highest throughput achievable using such a bus is 528 MB sec PCI X An enhanced version of PCI version 2 2 It supports one PCI slot per bus when running at 133 MHz two slots when running at 100 MHz and four slots when running at 66 MHz It is intended to provide throughputs in excess of 1 GB sec using a 64 bit wide 133 MHz implementation PlatinumRAID Pro Owner s Manual D Glossary Performance Performance is an important criterion on which a customer judges a RAID controller There are a number of popular benchmarking utilities that are available to measure the I O performance of a controller Some of these utilities simulate specific real life applications and provide the user a score indicating the controller s overall performance in that niche Others allow the user to specify tests with specific I O characteristics and generate throughput numbers corresponding to each specification The nature of the tests a user may wish to conduct on a controller depends on the application space in which that controller is anticipated to be deployed Physical Drive A single tangible drive is referred to as a physical drive Primary Storage Main
