Chapter 3: MegaRAID SAS RAID Controller Characteristics
6Gb/s MegaRAID SAS RAID Controller Family
The MegaRAID SAS 9271-8iCC RAID controller controls eight internal SAS+SATA ports through two SFF-8087 mini
SAS 4i internal connectors. This RAID controller ships as standard with CacheCade (CC) Pro 2.0 and Fast Path software
enabled out of the box.
3.1.7.1 MegaRAID SAS 9271 RAID Controller – Board Layout and Jumper/Connector Information
This subsection provides the board layout, and the connector and jumper information for the MegaRAID SAS 9266-8i
RAID controller.
The following figure shows the jumpers and the connectors on the RAID controller. The jumpers are set at the factory,
and you usually do not need to change them.
Figure 18 Layout of the MegaRAID SAS 9271-8i RAID Controller
The following table describes the jumpers and the connectors on the MegaRAID SAS 9271 RAID controllers.
NOTE The MegaRAID SAS 9271-4i RAID controller does not contain the J5B1 connector, which supports
ports 4 to 7. The J5B1 connector is on the MegaRAID SAS 9271-8i RAID controller and on the MegaRAID
SAS 9271-8iCC RAID controller.

- Summary of 6gb s megaraid sata sas raid controller characteristics 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
- Note the number of devices varies depending on the megaraid product check the lsi website http www lsi com for specific details about your product 13
- Sas array limitations 13
- Table 1 6gb s megaraid sata sas raid controllers array limitations 13
- The following table lists the array limitations for the 6gb s megaraid sata 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
- They provide a scalable interface that supports up to 240 devices through the use of expanders 13
- They support narrow ports consisting of a single phy 13
- They support wide ports that consist of two three or four phys within a single quad port 13
- They transfer data by using scsi information units 13
- This section describes the array limitations of the 6gb s megaraid sata 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

- 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
