PE310G4I40-T Descripción general
A 10 Gigabit Ethernet (10GbE) Network Interface Card (NIC) is a server-class adapter that connects a host system to a copper or fibre 10Gbps Ethernet network. Within the broader networking hierarchy, a NIC belongs to the data link / layer-2 adapter category, sitting between the host PCIe bus and the physical (PHY) Ethernet transceiver. Server-grade 10GbE adapters like the PE310G4I40-T typically implement NIC partitioning, SR-IOV, checksum offload, and large send offload to accelerate virtualised and high-throughput workloads, offloading work that would otherwise consume CPU cycles from the host.
Key features of the PE310G4I40-T include four RJ45 10GBase-T ports backed by the Intel X540 MAC+PHY silicon, PCI Express 3.0 x8 host-side bus for sufficient headroom across all four ports, low-profile bracket compatibility, and a typical server-grade MTBF in the order of 91 years per Telcordia SR-332 Issue 2. The Intel X540 controller provides hardware offloads including TCP/UDP checksum, LSOs, RSS, and VMDq/SR-IOV support, common to enterprise NIC deployments.
From an architecture standpoint, the X540 integrates four 10GBase-T PHYs together with PCI Express MAC and DMA engines, allowing the entire card to be a single-chip MAC+PHY solution (with magnetics on each RJ45). This integration enables the quad-port board layout to fit into a half-height, half-length (HHHL) form factor while maintaining full line-rate 10Gbps per port. The card operates from the PCIe slot power rails only (no external power connector documented in the standard datasheet cover).
Typical applications include virtualised server connectivity, network function virtualisation (NFV) nodes, high-performance storage back-ends using iSCSI or NFS over 10GbE, top-of-rack server links for database clusters, and upgrade paths for legacy servers that need 10GBase-T copper aggregation. Customers often standardise on the PE310G4 family to consolidate four ports onto one PCIe slot, freeing an adjacent slot for storage or accelerator cards.
When designing with the PE310G4I40-T, confirm that the host motherboard provides PCIe 3.0 x8 lane availability at the target slot; the X540 can operate in x4 and x8 slots but full quad-port line-rate requires x8 lanes of PCIe 3.0 or better. Note that this part is now marked EOL by Silicom, so availability for new designs should be verified and a successor or alternative cross-brand part may need sourcing. Cabling should be CAT6A or better for full 10GBase-T runs longer than 55 metres, per IEEE 802.3an guidelines cited in enterprise deployment guides.

Aplicaciones típicas
PE310G4I40-T es adecuado para 6 aplicacións: Virtualised Server Network Aggregation, Network Function Virtualisation (NFV) Node Uplinks, Database Cluster Back-end Storage Link, High-End Network Appliance Port Expansion, Legacy Server 10G Upgrade Path, Top-of-Rack 10GBase-T Server Connections.
Virtualised Server Network Aggregation
The PE310G4I40-T provides four 10GBase-T RJ45 ports backed by Intel X540 silicon in a single PCIe 3.0 x8 slot, ideal for virtualised server deployments that need to provision dedicated bandwidth to multiple VMs. Hardware offloads such as SR-IOV and VMDq (standard on X540) allow hypervisors to map virtual functions directly to guest OSes, minimising vSwitch overhead. Compared with dual-port NICs, the quad-port density halves PCIe slot consumption and aggregate per-port TCO in VMware ESXi or KVM server farms where uplink bandwidth per host exceeds 20 Gbps. Cabling uses standard CAT6A copper, which simplifies rack cabling versus fibre infrastructure.
Recomendado
Network Function Virtualisation (NFV) Node Uplinks
NFV nodes require multiple high-throughput uplink paths for service chaining (firewall → DPI → load balancer) and the PE310G4I40-T offers exactly four RJ45 10GBase-T ports on one Intel X540 chip, fitting a half-height low-profile slot. Hardware RSS and checksum offload preserve CPU cycles for VNF data-plane processing, while SR-IOV allows direct PCIe function assignment per VNF. This makes the card suitable for uCPE / edge-computing appliances that must expose multiple network services through a single host, where fibre infrastructure is unavailable.
Recomendado
Database Cluster Back-end Storage Link
Database clusters running MySQL, PostgreSQL, or NoSQL workloads over iSCSI / NFS over 10GbE benefit from the PE310G4I40-T's quartet of ports to bond multiple storage links and isolate replication traffic from client-facing connections. The Intel X540 silicon supports large send offload (LSO), reducing CPU cost for big sequential writes such as checkpoint flushes and dump loads. Aggregating four 10G links with LACP achieves effective 40 Gbps throughput per host, helping sustain low-latency storage transactions without dropping into TCP retries.
Recomendado
High-End Network Appliance Port Expansion
The Silicom PE310G4I40-T enables network appliance OEMs (UTM gateways, IDS / IPS probes, VPN concentrators) to deliver a 4x10GbE port density in a single HHHL slot, leveraging the standard Intel X540 driver ecosystem across Linux / FreeBSD. This accelerates time-to-market compared with designing a custom multi-NIC appliance, and reduces validation cost because the IXGBE driver is already battle-tested on every major server OS. Bracket compatibility with low-profile chassis supports 1U rack-mount appliance designs where slot height is constrained.
Recomendado
Legacy Server 10G Upgrade Path
Many existing servers with PCIe 2.0 / 3.0 slots cannot accept full-height NIC cards but support low-profile brackets. The PE310G4I40-T explicitly targets this upgrade market: a half-height quad-port 10GBase-T card that drops into existing server slots and immediately upgrades legacy 1G servers to 10G copper aggregation. Customers can use the existing CAT6A cabling infrastructure and avoid fibre trenching, which materially shortens the migration window. Per-port cost is competitive with single-port upgrades because one card replaces four discrete Gigabit NICs.
Recomendado
Top-of-Rack 10GBase-T Server Connections
Top-of-rack (ToR) servers that aggregate multiple traffic flows (east-west VM traffic plus north-south client traffic) benefit from the PE310G4I40-T splitting four 10GBase-T ports into different VLANs. This isolates replication, backup, and user traffic on the same card without dedicating multiple NICs. Intel X540's VMDq and SR-IOV assist in virtual environments, ensuring that NIC queues map cleanly to VM vCPUs for predictable throughput. The card's PCIe 3.0 x8 interface provides ample headroom for line-rate across all four ports simultaneously, which older PCIe 2.0 x8 cards cannot guarantee.

Notas de diseño
The PE310G4I40-T is a half-height, half-length (HHHL) add-in card. Confirm that the target chassis supports HHHL brackets or has an included full-height replacement bracket option. Reserve a PCIe 3.0 x8 (or PCIe 2.0 x8 with degradation) slot adjacent to system airflow vents; the card consumes slot power only and produces moderate heat through the X540 silicon, so clear airflow within the slot keep-out region is recommended.
Estimated thermal envelope: the Intel X540 silicon TDP is approximately 11 W across four ports operating at line-rate, so the card's local junction temperature rise under full load is moderate. In a 1U chassis with 10–15 W per slot of cooling budget, deploy additional airflow verification. The card includes no active fan; passive heatsink-only cooling relies on chassis airflow. Verify the datasheet thermal guidance for elevated-temperature deployments before designing into industrial or NEBS environments.
Two common pitfalls: (1) using CAT6 instead of CAT6A cabling for 10GBase-T — CAT6 is rated only for short 10G runs and the link will fall back to 1G/100M on longer runs; (2) installing in a PCIe 2.0 x4 electrical slot — the four-port card needs PCIe 2.0 x8 (or PCIe 3.0 x8) for full line-rate; x4 backplane slots will throttle throughput. Also note that the part is EOL, so engineer for last-time-buy procurement and stock the card in production only after securing the forecast build quantity.
