Microsemi 2293400-R 1100-4i 12Gb/s SAS RAID controller

Microsemi 1100-4i 12Gb/s SAS HBA

The Microsemi 2293400-R is a 12Gb/s SAS host bus adapter that connects up to four SAS or SATA drives through a single SFF-8643 mini-SAS HD internal connector. It installs in a PCI Express 3.0 x8 slot and includes both full-height and low-profile brackets for flexible chassis fit. The card operates without embedded hardware RAID, presenting drives directly to the operating system for software-defined storage configurations.

Suits direct-attached storage builders.

This adapter suits administrators who want the operating system or a hypervisor to manage storage redundancy and performance. It supports Microsoft Windows, Red Hat Linux, SUSE Linux, CentOS, Ubuntu Linux and VMware ESXi, making it a fit for heterogeneous server farms. Buyers who require on-board RAID 0, 1, 5 or 10 acceleration should look at a controller with an embedded RAID processor instead.

Verify PCIe 3.0 x8 slot and SFF-8643 cabling

Before ordering, confirm the host system has an available PCI Express 3.0 x8 slot and sufficient physical clearance for a card measuring 2.54 by 6.60 inches. Ensure the backplane or drive cages use SFF-8643 mini-SAS HD connectors, or source compatible breakout cables for the four internal ports. The board is RoHS compliant and rated for standard server operating environments.
