Appendix A: Introduction to Serial Attached SCSI ● 64 How Do SAS De vices Communicate? SAS devices comm unicate w ith each other th rough links. A link is a physical c onnection between tw o phys.
Appendix A: Introduction to Serial Attached SCSI ● 65 What’s a SAS Port? Note: Because the ph ysical link between SAS devices is from ph y to phy , rather than por t to por t, a “por t” is more of a vir tual concept, di fferent from what is nor mally considered a por t on other types of RAID controllers and storage devices.
Appendix A: Introduction to Serial Attached SCSI ● 66 How are Disk Driv es Identified in SAS? In the BIOS and in the management u t ilities (see page 55 ), disk dr ives ar e identified with numbers .

B Under standing RAID In this appendix... U nderstanding Drive Segments ............................................................................................. 70 N onredundant Arrays (RAID 0) ............................................... ....
Appendix B: Understanding RAID ● 70 Understanding Drive Segments A drive s egme nt is a disk dr iv e or portion of a disk dr iv e that is used to create an array . A disk drive can incl ude both RAID seg ments (segments that are part of an array) and available segments.
Appendix B: Understanding RAID ● 71 RAID 1 Arra ys A RAID 1 array is built fr om two disk driv es, where one disk driv e is a mi rror of the other (the same data is stored on each disk driv e).
Appendix B: Understanding RAID ● 72 RAID 10 Arra ys A R AI D 10 a r r ay i s b u il t fro m t wo o r m ore e qu a l- si z ed RA I D 1 a rr a ys . D a ta i n a RA I D 1 0 ar r ay is both str iped and mi rrored. Mirroring provides data protection, and stripi ng improv es performance.
Appendix B: Understanding RAID ● 73 RAID 5 Arra ys A RAID 5 array is bui lt from a minimum o f three disk driv es, and uses data striping and parity data to pr ovide redundancy . P ar ity data pro v ides data prot ection, and str iping impr oves performance.
Appendix B: Understanding RAID ● 74 RAID 5EE Arra ys A RAID 5EE array—also known as a hot space —is similar to a RAID 5 array e xcept that it includes a distributed spare drive and must be built from a minimum of four disk driv es.
Appendix B: Understanding RAID ● 75 RAID 50 Arra ys A RAID 50 array is built fr om six to fort y-eight disk drives configur ed as two or more RAID 5 arrays, and stripes stored dat a and par ity data across all disk driv es in both RAID 5 arrays. (Fo r more inf or mation, see RAID 5 A r ra y s on page 73 .
Appendix B: Understanding RAID ● 76 RAID 6 Arra ys A RAID 6 array—also known as dual drive fail ure protection—is similar to a RAID 5 array because it uses data striping and par ity data to provide redundancy . How e ver , RAID 6 arr ays include tw o independent sets of parity data instead of one.
Appendix B: Understanding RAID ● 77 Selecting the Best RAID Le vel U se this table to select the RAID lev els that are most appr opri ate for the logical dr ives on y our storage space, based on the number of availa ble disk dr ives and y our requirements f or performance and reliability .
