The escalating networking, and proven, reliable performance. deployments of servers with multi-core processors and demanding To ensure maximum flexibility, Intel supports the ability to mix applications such as High Performance Computing (HPC), database any combination of the SFP+ optical modules, direct attach clusters, and video-on-demand are the types of applications driv- copper cables, or 1000BASE-T SFP modules on the Intel Ethernet ing the need for 10 Gigabit connections. Customers require flexible X520 Adapters . For instance, customers can remove the optical modules that come installed on the adapter and replace them and scalable I/O solutions to meet the rigorous requirements of with an Intel Ethernet SFP+ Optic, an SFP+ Direct Attach Copper running mission-critical applications in virtualized and unified Cable, or a 1000BASE-T SFP module. Intel Ethernet SFP+ Optics storage environments. are available in both short range (SR) 850 nm and long range (LR) 1310 nm options. Powered by Intels third-generation 10 GbE network controller, the Intel Ethernet 82599 10 Gigabit Ethernet Controller, the This enables customers to create the configuration that best X520 server adapter family addresses the demanding needs meets the needs of their data center environment.General Specifications Network Standards Physical Layer Interface SR 1000BASE-SX 1G Ethernet 10GBASE-SR 10G Ethernet LR 1000BASE-LX 1G Ethernet 10GBASE-LR 10G Ethernet SFP+ Module Specifications E lectrical interface: SFF-8431 Rev 4.1 I 2C Register interface: SFF-8472 Rev 10.4 M echanical: SFF-8432 Rev 5.0 Product Codes E10GSFPSR Intel Ethernet SFP+ SR Optic E10GSFPLR Intel Ethernet SFP+ LR Optic Compatible Intel Ethernet Server Adapters E10G42BTDA Intel Ethernet Server Adapter X520-DA2 E10G41BFSR Intel Ethernet Server Adapter X520-SR1* E10G42BFSR Intel Ethernet Server Adapter X520-SR2* E10G41BFLR Intel Ethernet Server Adapter X520-LR1* * Ships with pluggable optic installed Note: O ther brands of SFP+ optical modules will not work with the Intel Ethernet Server Adapter X520 Series.
