- Sas is a serial point to point enterprise level device interface that leverages the proven scsi protocol set sas is a convergence of the advantages of sata scsi and fibre channel and it is the future mainstay of the enterprise and high end workstation storage markets sas offers a higher bandwidth per pin than parallel scsi and it improves signal and data integrity 10

- The following figure shows an example of a sas raid controller configured with an lsisasx12 expander that is connected to sas drives sata iii drives or both 10
- The sas interface uses the proven scsi command set to ensure reliable data transfers while providing the connectivity and flexibility of point to point serial data transfers the serial transmission of scsi commands eliminates clock skew challenges the sas interface provides improved performance simplified cabling smaller connectors lower pin count and lower power requirements when compared to parallel scsi 10

- Although you can have up to 16 virtual drives per drive group and up to 128 drive groups on most of the controllers a limit of 64 virtual drives exists on those controllers 13
- Data transfer using scsi information units 13
- Sas array limitations 13
- Support of narrow ports consisting of a single phy 13
- Support of wide ports that consist of two three or four phys within a single quad port 13
- The following table lists the array limitations for the megaraid 6gb s sas raid controllers 13
- The maximum numbers in the previous table depend on how many physical devices you have connected to the raid controller for example the maximum number of drive groups is equal to the number of drives that are supported by the controller thus for the megaraid sas 9240 4i raid controller the maximum number of drive groups per controller is 16 which is based on the maximum number of physical devices that you can connect in addition the maximum number of hot spares per controller is equal to the maximum number of drives per controller 13
- These raid controllers support 64 bit logical block addressing lba which makes it possible to connect a large number of drives to the raid controller directly and through expanders however the actual number of drives that you can attach depends on the limits listed in this table rather than by actual raid volume capacity 13
- This section describes the array limitations of the megaraid 6gb s sas raid controllers these limitations include the number of drives supported per controller the maximum number of drives per controller and the maximum number of virtual drives allowed per controller 13
