Green low-profile PCIe card with eight internal connectors

Broadcom

Broadcom MegaRAID 9540-8i RAID controller 8 ch 240 dev PCIe 4.0 x8 05-50134-03

SKU CH-8DTM-FZW38 MPN 05-50134-03

A low-profile RAID controller with eight channels supporting up to 240 SATA, SAS and NVMe devices over a PCIe 4.0 x8 bus

  • 8 internal channels connect up to 240 drives
  • PCIe 4.0 x8 bus delivers 4.0 GT/s per lane bandwidth
  • SATA 6Gb/s and SAS 12Gb/s support covers HDD and SSD arrays
  • NVMe pass-through enables direct PCIe 4.0 storage access
  • Low-profile plug-in card fits 3U and denser server chassis

MegaRAID 9540-8i RAID controller

The Broadcom MegaRAID 9540-8i is a low-profile storage controller that installs in a PCIe 4.0 x8 slot. It manages up to 240 SATA or SAS drives across eight internal channels. The card supports NVMe devices through the same PCIe 4.0 interface. It is built for servers and workstations that need hardware RAID acceleration.

Suits arrays up to 240 drives

This controller fits administrators who need a single card to handle large SAS or SATA arrays with hardware RAID offload. It is not for systems that lack a PCIe 4.0 x8 slot or that require external drive connectivity. Builds limited to PCIe 3.0 bandwidth or low-profile clearance constraints should verify compatibility before purchase.

Eight channels and 240-device limit

The eight internal channels set the physical connection count, while the 240-device maximum defines the logical scaling ceiling. Both numbers must match the planned array size and drive topology. Exceeding either limit will require additional controllers or a different model.

Punti di forza

  • 8 internal channels connect up to 240 drives
  • PCIe 4.0 x8 bus delivers 4.0 GT/s per lane bandwidth
  • SATA 6Gb/s and SAS 12Gb/s support covers HDD and SSD arrays
  • NVMe pass-through enables direct PCIe 4.0 storage access
  • Low-profile plug-in card fits 3U and denser server chassis

Domande su questo articolo

What does the 240-device limit mean once this card is installed?

The controller can manage up to 240 storage devices across its eight channels when expanders are used.

How does the PCIe 4.0 x8 interface cap real-world throughput?

PCIe 4.0 x8 provides the bus bandwidth for SATA 6Gb/s, SAS 12Gb/s and NVMe traffic.

What slot and bracket does the 9540-8i need to fit?

It requires a PCIe x8 or wider slot and uses a low-profile bracket.
