Detailed Specifications
Intel E10G42BFSR Network Adapter
Overview :
The Intel E10G42BFSR is an enterprise-class dual-port 10 Gigabit Ethernet (10GbE) short-range fiber network interface adapter from the X520 server series. Purpose-built to optimize high-density multi-tenant cloud architectures, virtualized enterprise server banks, and network-attached storage pipelines, this PCI Express component addresses intense bandwidth congestion. It delivers highly reliable, short-range optical connectivity to securely accelerate modern data center transformation.
Powered by the high-performance Intel 82599ES 10 Gigabit Ethernet Controller chipset, the network adapter includes native hardware-level stateful and stateless offloads. It integrates dual Small Form-factor Pluggable Plus (SFP+) cages pre-populated with 10GBASE-SR short-range LC duplex multi-mode fiber transceivers, accommodating reliable data transit distances up to 300 meters. The board deploys advanced Intel Virtualization Technology for Connectivity (Intel VT-c), optimizing hypervisor layout execution via Single Root I/O Virtualization (SR-IOV) and Next-Generation Virtual Machine Device Queues (VMDq) to guarantee near-native I/O speeds.
This optical server adapter interfaces through a physical PCI Express 2.0 x8 slot profile, sliding directly into full-height or low-profile expansion bays on mainstream rack or blade systems. Operating with a low 10.7W maximum Thermal Design Power footprint, it dramatically scales system performance while minimizing localized heat production. The implementation of Receive Side Scaling (RSS) and Direct Cache Access (DCA) safely routes inbound network traffic across available multi-core processor blocks to prevent processing choke points.
The controller supplies native unified storage networking infrastructure by concurrently managing standard TCP/IP traffic along with hardware-accelerated Fibre Channel over Ethernet (FCoE) and iSCSI target protocols on a single physical link. Do not deploy this hardware inside legacy non-PCIe environments or over single-mode long-range fiber paths without replacing the native transceivers. Active chassis airflow is necessary to safely cool the on-board aluminum heat sink under full duplex operational limits.
Key Features :
Dual 10GBASE-SR SFP+ LC fiber interfaces move data up to 300 meters.
Single-chip Intel 82599ES controller slashes host virtualization overhead.
Native SR-IOV and VMDq offloads bypass virtual switches for raw throughput.
Consolidated storage convergence runs LAN, iSCSI, and FCoE streams together.
Low 10.7W maximum power footprint preserves rack-level thermal efficiency.
