SKU CH-QZR3-HG3P2

Connects 24 internal SAS and SATA drives at up to 12Gb/s over eight PCIe 3.0 lanes using SFF-8643 connectors

  • 24 internal SAS and SATA ports at 12 Gb/s each
  • Eight-channel PCIe 3.0 full duplex bandwidth
  • 24 SFF-8643 connectors for dense drive attachment
  • SAS link rates of 3, 6 and 12 Gb/s supported

24-port SAS 12Gb/s HBA

The LSI 9305-24i is a host bus adapter that provides 24 internal SAS and SATA ports running at up to 12Gb/s each. It connects through an eight-lane PCIe 3.0 interface and uses SFF-8643 connectors for internal cabling. The card operates in IT mode for direct drive access without hardware RAID abstraction.

Sustained throughput with eight PCIe lanes

Eight lanes of PCIe 3.0 give the adapter enough bandwidth to keep all 24 ports active at 12Gb/s simultaneously without bottlenecking the bus. Link rates automatically negotiate down to 6Gb/s or 3Gb/s when slower drives are attached, so mixed generations run at their native speeds. Builders who need external ports or hardware RAID offload should look at a different model.

Questions about this item

How much power and heat does the 9305-24i produce when running all day?

The card uses an eight-channel PCIe 3.0 interface, so power draw and heat output stay within the slot's standard limits during continuous operation.

What cables or backplane do I need to use the 24 SFF-8643 ports on this HBA?

You need mini-SAS HD cables or a backplane with SFF-8643 connectors to attach up to 24 SAS or SATA drives at 12Gb/s.
