Broadcom BCM957414A4142CC P225P Dual-Port 25Gb SFP28 PCIe3.0 x8 25G 光纤网卡

Basic Parameter Table

Core Product Features

1. Broadcom enterprise dual-port 25G optical network adapter based on BCM57414 controller chip, SFP28 modular optical port design, flexible matching of 25G/10G optical transceivers for long-distance fiber transmission.
2. Two independent SFP28 slots, single port up to 25G bandwidth; PCIe3.0 x8 full-duplex bus eliminates high-throughput bottlenecks for all-flash storage clusters and virtualization heavy-load hosts.
3. Full enterprise hardware offload suite: TCP/UDP checksum offload, TSO large segment offload, RSS multi-queue receive balance, VLAN tag segmentation, SR-IOV hardware virtualization partitioning, compatible with VMware ESXi, Linux, Windows Server.
4. Large-area passive black heatsink, ultra-low power consumption, stable 24/7 silent operation in rack data center servers; full-height & low-profile mounting brackets included for standard/slim chassis.
5. Standard IEEE compliant, supports LACP link aggregation, jumbo frames up to 9000 bytes; fiber transmission distance up to 10km+ (depends on SFP28 optical module).
6. Modular optical design advantage: flexible selection of short/long-distance fiber modules, suitable for inter-rack storage networking and cross-room server interconnection scenarios.

Application Scenarios

1. All-flash storage cluster uplink: ZFS/NAS mass storage server high-speed uplink, database core storage redundant dual-link network.
2. Virtualization computing host: Cloud computing heavy IO virtual machine uplink, high-performance computing node interconnection.
3. Data center inter-rack cross-server high-speed transmission, medium-long distance cabinet interconnection (far exceeding 100m copper cable limit).
4. Not applicable: Short-distance desktop internal wiring without fiber deployment.
