LSI Logic 9305-24i 24-Port SAS 12Gb/s PCI-Express 3.0 Host Bus Adapter

SKU CH-9R5F-SXWPQ

A 24-port SAS 12Gb/s HBA connects up to 1024 drives via expanders, delivering 1.5 million IOPS over PCIe 3.0

  • 24 internal ports connect up to 24 SAS or SATA drives directly
  • 6 Mini SAS HD SFF-8643 connectors simplify cabling for dense enclosures
  • PCIe 3.0 x8 host bus delivers 6,400 MB/s throughput for demanding workloads
  • Over 1.5 million IOPS from the SAS 3224 controller accelerates performance-sensitive applications
  • Supports up to 1,024 devices through expanders for massive storage scaling

24-Port SAS 12Gb/s HBA

The LSI Logic 9305-24i is a low-profile host bus adapter that connects up to 24 SAS or SATA drives directly through six internal Mini SAS HD SFF-8643 connectors. It uses the SAS3224 controller on a PCI Express 3.0 x8 interface to deliver 6,400 MBps throughput and over 1.5 million IOPS for direct-attach storage.

Suited for non-RAID JBOD deployments

This card suits administrators who need maximum port density for software-defined storage, ZFS pools, or backup targets running Windows, Linux, VMware, FreeBSD or Solaris. It is not suited for builds that require hardware RAID acceleration or external drive connectivity without additional cabling.

PCIe 3.0 x8 host interface

The adapter requires a PCI Express 3.0 x8 slot and draws 16.2 W typical power from +12 V and 3.3 V rails. Operating temperature ranges from 0 to 55 °C with 5 to 90 % non-condensing humidity. Passive copper and active optical cables are supported for internal drive links.
