LSI Logic megaraid sas 9260-8i kit [13/92] Sas array limitations

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

Summary of 6gb s megaraid sata sas raid controller characteristics 11

Sas features 12

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

Connecting a sas raid controller with internal connectors to the drives 25

Figure 6 sas plugs and sata plugs and sas backplane receptacle connector 25

Follow these steps to connect your raid controller with internal sas port connectors directly to sas drives or sata drives 25

If you have another drive connect it to another plug on the internal cable 25

Insert the sff 8087 x4 internal mini sas connector on the cable into a sff 8087 x4 internal mini sas connector on the megaraid sas 9260 8i raid controller as shown in the following figure 25

Note the megaraid sas 9260 8i raid controller is shown as an example you can connect other megaraid sas controllers with internal sas port connectors in the same way 25

Plug the hdd connector on the other end of the internal cable into the connector on the sas drive or the sata drive 25

The following subsections provide step by step instructions for connecting the megaraid sas raid controllers to sas drives and sata drives either directly or through an expander 25

This section provides step by step instructions for connecting the sas cable from the internal connectors on the raid controller to sas drives and sata drives 25
