Single-port 100GbE QSFP28 adapter

The LR-LINK LRES1019PF-QSFP28 is a single-port 100GbE network adapter built on the Intel E810 chip. It connects through a PCI Express 4.0 x16 slot and carries one QSFP28 cage for fibre connectivity. The card targets servers that need high-throughput, low-latency Ethernet for virtualization, storage or high-performance computing workloads.

PCIe 4.0 x16 slot with dual-bracket fit

The adapter uses a full PCIe 4.0 x16 electrical interface and is backward compatible with PCIe 3.0 systems. Both low-profile and full-height brackets are supported, allowing installation in standard rack servers or space-constrained blade chassis. A single QSFP28 port accepts compatible 100G transceivers or direct-attach cables for straightforward fibre deployment.

0 to 55 ℃ operating range with RDMA offload

Rated for 0 ℃ to 55 ℃ and up to 90 % non-condensing humidity, the card is designed for typical data-centre environments. Hardware offload for iWARP and RoCEv2 RDMA reduces CPU overhead during heavy data movement. Precision Time Protocol IEEE 1588 v1 and v2 with per-packet time stamping supports synchronised workloads across the cluster.

Küsimused selle toote kohta

What practical throughput limit does the PCIe 4.0 x16 interface impose on this 100GbE card?

The PCIe 4.0 x16 link provides up to 16 GT/s per lane, giving ample headroom so the 100 Gbps Ethernet port can run at line rate without bus saturation.

Which bracket heights are supplied for mounting the LRES1019PF-QSFP28 in a server chassis?

The adapter ships with both a low-profile bracket and a full-height bracket, allowing installation in 1U racks or standard tower servers.

What driver step is often missed when installing this Intel E810-based adapter on Linux?

After loading the kernel module, create the needed virtual functions with the SR-IOV sysfs interface; the 256 VFs do not appear until explicitly enabled.
