Host Bus Adapter with PCIe 3.0 x8

The Microsemi 2293300-R is a 12Gb/s SAS host bus adapter designed for PC and Linux platforms. It connects via a PCI Express 3.0 x8 interface and provides twelve external SAS ports using three SFF-8644 connectors. The low-profile form factor measures 2.5 by 6.6 inches and includes a vented bracket for installation flexibility.

Passive cooling and RoHS compliance

This adapter operates without an active fan, relying on the vented bracket and system airflow for thermal management. The passive design eliminates mechanical noise and reduces power draw during normal operation. Environmental certification confirms RoHS compliance, and the unit is rated for a three-year limited warranty period.

Sustained 12Gb/s throughput across twelve ports

Under continuous load the controller maintains 12Gb/s SAS signalling across all twelve external ports without throttling. The PCIe 3.0 x8 host link provides sufficient bandwidth to keep multiple SAS or SATA devices saturated during prolonged transfers. Steady-state performance is limited by the host bus and attached drives rather than the adapter itself.

Questions about this item

How is the HBA 1100-8e installed in a PCI Express 3.0 x8 slot and which bracket should be used?

Insert the card into a PCI Express 3.0 x8 slot; the package includes a low-profile vented bracket for slim chassis and a standard bracket for full-height cases.

What maintenance or replacement will the HBA 1100-8e need over its service life?

The adapter has no moving parts; keep the vented bracket clear of dust and verify firmware updates from the vendor for continued compatibility.

What throughput limit appears first when all twelve SFF-8644 ports run sustained 12 Gb/s SAS traffic?

The PCI Express 3.0 x8 host link caps aggregate bandwidth at roughly 64 Gb/s, so the bus saturates before the twelve 12 Gb/s SAS lanes can be fully utilised.
