Green circuit board with four Mini SAS HD ports and gold PCIe edge connector

LSI

LSI 9400-16i 12Gbps SAS/SATA HBA IT Mode 16/20-Port Network Card

SKU CH-M65N-RZAJP

12 Gbps SAS and 6 Gbps SATA controller with four SFF-8643 ports supporting 16 drives and NVMe protocol in IT mode

  • 12 Gbps SAS throughput for fast storage arrays
  • x8 PCI Express 3.0 lane for high-bandwidth connectivity
  • Four Mini SAS HD SFF-8643 ports link up to 16 drives
  • IT mode firmware enables 20-port NVME and SATA support

16-port SAS HBA for storage arrays

The LSI 9400-16i is a 12Gbps SAS/SATA host bus adapter that presents 16 internal ports through four Mini SAS HD SFF 8643 connectors. It installs in an x8 PCI Express 3.0 slot and ships in IT mode so the operating system manages every attached drive directly. This card targets builders assembling JBOD enclosures or software-defined storage nodes who need dense connectivity without a RAID layer.

Upgrades from 8-port or 6Gbps HBAs

Moving to this adapter adds port count and doubles the SAS link rate to 12Gbps while keeping the same PCIe 3.0 x8 interface. The jump is worth it when a single chassis must serve more than eight drives or when newer 12Gbps SAS SSDs and NVMe protocol hard disks would be bottlenecked on a 6Gbps controller. Buyers who only need a handful of SATA ports or who require hardware RAID offload should look elsewhere.

Questions about this item

What slot width does the 9400-16i need on the motherboard?

The card requires an x8 PCI Express 3.0 slot to operate at its rated 12Gbps SAS and 6Gbps SATA speeds.

How are the four Mini SAS HD SFF-8643 ports cabled, and what mistake do builders make?

Each SFF-8643 connector breaks out to four SATA or SAS drives; the common error is using forward breakout cables instead of the reverse pin-out required for backplane connections.
