to Serial Attached SCSI ● 71 What's a SAS Port? Note: Because the physical link between SAS devices is from phy to phy, rather than port to port, a "port" is more of a virtual concept, different from what is normally considered a port on other types of RAID controllers and storage devices - Adaptec 4805SAS | User Guide - Page 72
Introduction to Serial Attached SCSI ● 72 How are Disk Drives Identified in SAS? In the BIOS and in the management utilities (see Identifying Disk Drives on page 91), disk drives are identified in the following formats: ● CNX:DevY = Device Y is attached to Connector X (see Direct-attach Connections - Adaptec 4805SAS | User Guide - Page 73

combination of performance and redundancy. RAID levels also vary by the number of disk drives they support. This appendix describes the RAID levels supported by your Adaptec RAID controller, and provides a basic overview of each to help you select the best level of protection for your data storage. - Adaptec 4805SAS | User Guide - Page 76
Understanding Drive Segments A drive segment is a disk drive or portion of a disk drive that is used to create an array. A disk drive can include both RAID segments (segments that are part of an array) and available segments. Each segment can be part of only one logical device at a time. If a disk - Adaptec 4805SAS | User Guide - Page 77
one disk drive is a mirror of the other (the same data is stored on each disk drive). Compared to independent disk drives, RAID 1 arrays provide improved performance, with twice the read rate and an equal write rate of single disks. However, capacity is only 50 percent of independent disk drives - Adaptec 4805SAS | User Guide - Page 78
10 array is built from two or more equal-sized RAID 1 arrays. Data in a RAID 10 array is both striped and mirrored. Mirroring provides data protection, and striping improves performance. Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an array with - Adaptec 4805SAS | User Guide - Page 79
. Parity data is an error-correcting redundancy that's used to re-create data if a disk drive fails. In RAID 5 arrays, parity data (represented by Ps in the next figure) is striped evenly across the disk drives with the stored data. Drive segment size is - Adaptec 4805SAS | User Guide - Page 80
and can't be shared with other logical disk drives. A distributed spare improves the speed at which the array is rebuilt following a disk drive failure. A RAID 5EE array protects your data and increases read and write speeds. However, capacity is reduced by two disk drives' worth of space, which is - Adaptec 4805SAS | User Guide - Page 81
disk drives configured as two or more RAID 5 arrays, and stripes stored data and parity data across all disk drives in both RAID 5 arrays. (For more information, see RAID 5 Arrays on page 79.) Note: Because they support four disk drives only, the Adaptec 2420SA RAID controller can't support RAID 50 - Adaptec 4805SAS | User Guide - Page 82
