  • IT mode P20 firmware enables direct drive control for ZFS and unRAID
  • LSI SAS2208 controller delivers 6 Gbps SAS and SATA throughput
  • PCIe 3.0 x8 interface provides eight lanes of bandwidth
  • Eight internal ports via two SFF-8087 connectors support up to eight drives
  • Includes full-height and low-profile brackets for flexible installation

Eight-port 6Gbps SAS/SATA HBA

The LSI M5110 is an eight-port host bus adapter built around the LSI SAS2208 controller. It connects to a PCIe 3.0 x8 slot and ships with firmware in IT mode version P20 (20.00.07.00). Two SFF-8087 mini-SAS cables are included along with full-height and low-profile brackets.

Suited for ZFS, FreeNAS and unRAID arrays

This card targets builders who want direct drive control for software-defined storage without hardware RAID abstraction. The IT mode firmware presents each drive to the operating system for native management. Users needing on-board RAID processing or bootable hardware RAID volumes should consider a different adapter.

IT mode firmware P20 decides suitability

The defining specification is the factory-flashed IT mode firmware at version P20 (20.00.07.00). It removes RAID logic so the OS sees every attached SAS or SATA device individually. Verify that your platform can initialise a PCIe 3.0 x8 card and that IT mode matches your storage software requirements.

Questions about this item

Should I pick the 8-port version or a different port count for my storage array?

This card provides exactly 8 ports via two SFF-8087 connectors, so choose it when you need eight SAS or SATA drives connected to a single PCIe slot.

What does the 6Gbps rating mean when the card is installed in a server?

Each of the eight ports can transfer data at up to 6Gbps, so the practical limit per drive is 6Gbps whether you attach SAS or SATA disks.

Does the PCIe 3.0 x8 interface cap the total throughput of the eight ports?

The PCIe 3.0 x8 link offers far more bandwidth than eight 6Gbps ports can saturate, so the host bus will not bottleneck the controller.
