• In summary although sas and parallel scsi both use the scsi command set how they move data from one place to another is very different to support point to point serial data transport sas introduces new types of connectors cables connection options and terminology generally speaking sas is faster and more flexible than parallel scsi and provides more options for building your storage space sas lets you mix sas and sata disk drives together and lets you connect many many more devices this table describes many of the main differences between the two interfaces p.77
• How is sas different from parallel scsi p.77
• When you create arrays or logical drives you can assign a raid level to protect your data each raid level offers a unique 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 p.78
• Understanding drive segments p.78
• Non redundant arrays raid 0 p.78
• B understanding raid p.78
• An array with raid 0 includes two or more disk drives and provides data striping where data is distributed evenly across the disk drives in equal sized sections however raid 0 arrays do not maintain redundant data so they offer no data protection compared to an equal sized group of independent disks a raid 0 array provides improved i o performance drive segment size is limited to the size of the smallest disk drive in the array for instance an array with two 250 gb disk drives and two 400 gb disk drives can create a raid 0 drive segment of 250 gb for a total of 1000 gb for the volume as shown in this figure p.78
• 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 drive is not part of any logical device the entire disk is an available segment p.78
• Raid 1 arrays p.79
• Raid 1 enhanced arrays p.79
• Raid 10 arrays p.80
• A raid 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 two 250 gb disk drives and two 400 gb disk drives can create two mirrored drive segments of 250 gb for a total of 500 gb for the array as shown in this figure p.80
• Raid 5 arrays p.81
• A raid 5 array is built from a minimum of three disk drives and uses data striping and parity data to provide redundancy parity data provides data protection and striping improves performance 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 limited to the size of the smallest disk drive in the array for instance an array with two 250 gb disk drives and two 400 gb disk drives can contain 750 gb of stored data and 250 gb of parity data as shown in this figure p.81
• Raid 5ee arrays p.82
• A raid 5ee array also known as a hot space is similar to a raid 5 array except that it includes a distributed spare drive and must be built from a minimum of four disk drives unlike a hot spare a distributed spare is striped evenly across the disk drives with the stored data and parity data 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 for parity data and spare data in this figure s represents the distributed spare p represents the distributed parity data p.82
• Raid 50 arrays p.83
• A raid 50 array is built from six to forty eight 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 81 the parity data provides data protection and striping improves performance raid 50 arrays also provide high data transfer speeds drive segment size is limited to the size of the smallest disk drive in the array for example three 250 gb disk drives and three 400 gb disk drives comprise two equal sized raid 5 arrays with 500 gb of stored data and 250 gb of parity data the raid 50 array can therefore contain 1000 gb 2 x 500 gb of stored data and 500 gb of parity data in this figure p represents the distributed parity data p.83
• Use this table to select the raid levels that are most appropriate for the logical drives on your storage space based on the number of available disk drives and your requirements for performance and reliability p.84
• Similar to a raid 50 array see raid 50 arrays on page 83 a raid 60 array also known as dual drive failure protection is built from eight disk drives configured as two or more raid 6 arrays and stripes stored data and two sets of parity data across all disk drives in both raid 6 arrays two sets of parity data provide enhanced data protection and striping improves performance raid 60 arrays also provide high data transfer speeds p.84
• Raid 60 arrays p.84
• Raid 6 arrays p.84
• Comparing raid levels p.84
• A raid 6 array also known as dual drive failure protection is similar to a raid 5 array because it uses data striping and parity data to provide redundancy however raid 6 arrays include two independent sets of parity data instead of one both sets of parity data are striped separately across all disk drives in the array raid 6 arrays provide extra protection for your data because they can recover from two simultaneous disk drive failures however the extra parity calculation slows performance compared to raid 5 arrays raid 6 arrays must be built from at least four disk drives maximum stripe size depends on the number of disk drives in the array p.84
• Disk drive usage read performance and write performance depend on the number of drives in the logical drive in general the more drives the better the performance p.85
