Low-profile RAID controller card with eight U.2 NVMe ports

HighPoint Technologies, Inc.

HighPoint Technologies, Inc. R 1180 RAID controller 8x U.2 NVMe PCIe 3.0 x16

SKU CH-4W45-A3H0C MPN R 1180

Adds eight U.2 NVMe drives via a single PCIe 3.0 x16 slot in a low-profile card

  • Eight U.2 NVMe drives on one low-profile card
  • Dedicated PCIe 3.0 x4 lane per port for full bandwidth
  • PCIe 3.0 x16 bus interface delivers 8 GT/s transfer rate
  • Low-profile form factor fits 2.71" height chassis slots
  • Compact 6.55" x 0.83" board weighs 0.93 lbs

HighPoint Rocket 1180 eight-port NVMe HBA

The HighPoint Rocket 1180 is a PCIe 3.0 x16 host bus adapter that adds eight internal U.2 ports to a server or workstation. Each port delivers a dedicated PCIe 3.0 x4 link for up to eight 2.5-inch U.2 NVMe SSDs. The low-profile form factor fits space-constrained chassis while providing high-density storage connectivity. It targets system builders who need maximum NVMe device count in a single slot.

Passive cooling with low-profile clearance

The card operates without an onboard fan, relying on system airflow across its compact 6.55 by 2.71 by 0.83 inch PCB. Passive thermal design keeps noise at zero while maintaining stability for sustained NVMe workloads. Power draw is limited to the slot and attached drives, avoiding auxiliary connectors. Builders must ensure case ventilation supplies adequate airflow over the heatsink area.

Low-profile bracket and eight U.2 connectors

A low-profile bracket is fitted for 2U or slim enclosures, while the eight U.2 ports accept standard 2.5-inch drive cables or backplanes. Each connector carries a full x4 electrical link, so cable routing must preserve signal integrity for 8 GT/s operation. The 0.93 lb weight adds minimal stress to the motherboard slot. Systems without eight internal U.2 bays cannot use the full port count.

Pitanja o ovom artiklu

How is the R 1180 installed and what step is often missed?

Insert the low-profile card into a PCIe 3.0 x16 slot and connect eight U.2 cables to the ports; the step often missed is ensuring each cable carries a dedicated PCIe 3.0 x4 link to every drive.

What maintenance or replacement will the R 1180 need later?

The controller has no moving parts; plan to replace the eight U.2 cables if they show wear, and verify drive firmware updates through the host system.

What limit appears first on the R 1180 under sustained use?

Each of the eight ports is capped at a PCIe 3.0 x4 link running at 8 GT/s, so aggregate throughput hits that per-port ceiling before the x16 host slot saturates.
