16-Port SAS/SATA RAID Controller

The LSI RocketRAID 2840C is a PCIe 3.0 x8 host bus adapter that provides 16 internal 6Gb/s SAS and SATA ports through four SFF-8643 connectors. It supports RAID 0, 1, 5, 6, 1/0, 5/0, JBOD and single-disk modes for up to 16 enterprise-class hard drives and is managed through a cross-platform suite for Windows, macOS and Linux.

Who this suits

This card suits builders adding high-density internal storage to servers or workstations that run Windows, macOS or Linux and need hardware RAID across many spindle drives. It is not for systems that lack a PCIe 3.0 x8 slot or for configurations that require external drive connectivity.

Deciding specification

The single specification that decides fit is the four SFF-8643 ports delivering 16 lanes of 6Gb/s SAS/SATA connectivity; the backplane or cables must match this connector and the chassis must accommodate the x8 card length.

Highlights

  • 16 ports connect up to 16 SAS or SATA drives
  • PCIe 3.0 x8 host interface delivers 6 Gb/s per port
  • Four SFF-8643 connectors simplify high-density cabling
  • RAID 0, 1, 5, 6, 1/0, 5/0 and JBOD cover diverse storage needs
  • Unified management suite runs on Windows, macOS and Linux

Questions about this item

How do I install the RocketRAID 2840C into a PCIe 3.0 x8 slot and what step is commonly missed?

Insert the card into a PCIe 3.0 x8 slot, secure the bracket, then connect up to four SFF-8643 cables to the 16 ports; the step often missed is enabling the controller BIOS or UEFI option ROM in the motherboard firmware so the RAID array appears during boot.

What maintenance or replacement will the 16-port controller need over time?

The controller itself has no moving parts, but the attached SAS or SATA hard drives will eventually require replacement; monitor SMART data through the management suite and swap any drive that reports reallocated sectors or excessive seek errors.

What limit appears first when all 16 ports run sustained workloads?

The PCIe 3.0 x8 host link caps aggregate throughput at roughly 8 GT/s per lane, so combined read or write traffic from all 16 drives will saturate the bus before the individual 6 Gb/s SAS or SATA ports reach their own ceiling.
