P411W-32P NVMe PCIe 4.0 switch adapter (model number 50054) provides high-performance storage
connectivity for servers and workstations. The adapter uses the PEX88048 PCIe 4.0 switch that provides a x16 PCIe 4.0,
16 GT/s interface to a host system with up to 32 PCIe 4.0 16 GT/s ports for NVMe device connection.
NVMe technology is a logical device interface specification used to access nonvolatile storage media that attach by using a
PCIe bus. Nonvolatile memory is usually flash memory in SSDs.
1 Features
This section lists the adapter features.
Supports 32 PCIe 4.0 lanes, which can be configured as x4, x2, and x1 ports for NVMe connectivity
Supports 16-lane, PCIe 4.0 host-interface performance
Supports PCIe link rates of 16 GT/s
Provides four internal x8 Slimline connectors (SFF-8654)
Complies with SFF-9402 sideband signaling
Offered with a full-profile bracket and a low-profile vented bracket
Provides one heartbeat LED and one system error status LED
Complies with
SFF-TA-1005 Specification for Universal Backplane Management (UBM)
2 PCIe Interface
PCIe is a high-speed standard local bus for point-to-point interfacing of I/O components to the processor and the memory
subsystems in high-end computers and servers. The PEX88048 switch provides the PCIe functionality for the adapter. The
PEX88048 switch connects directly to the PCIe bus and generates timing and protocol in compliance with PCIe
specifications.
The adapter supports 16-lane PCIe 4.0 16 Gb/s performance up to 256 Gb/s single direction and 512 Gb/s dual direction.
Each port supports PCIe speeds up to 16 Gb/s in each direction.
3 Operating System and Driver Support
The adapter does not require a driver for operation or communication to attached NVMe drives. The drives are presented
natively to the host and use the native NVMe drivers.
Use the inbox Fusion-MPT™ SAS driver for firmware updates. The following operating systems support the inbox
Fusion-MPT SAS driver. See
