Xframe E - 10 Gigabit Ethernet PCI Express Server & Storage Adapter

Xframe E

Xframe E is the newest member of Neterion’s Xframe 10 Gigabit Ethernet product family. PCI-Express (PCIe) is a next-generation I/O interconnect standard that is rapidly gaining traction in the server and storage world. The pairing of Neterion’s industry-leading Xframe technology with PCIe means that best-in-class Ethernet performance is available to more servers than ever before. The Xframe product family offers a unique multi-channel device model. A total of eight independent transmit and receive paths are available and each path may be prioritized for true Quality-of-Service support. By combining this novel architecture with the power of Extended Message Signalled Interrupts (MSI-X), Neterion has established a leading-edge framework for I/O Virtualization.

Capitalizing on Ethernet, a proven industry standard for 30 years, the Xframe E adapter allows end-users to preserve their existing environment: operating systems, network administration tools, core cabling, personnel training, and network infrastructure. Xframe E dramatically increases network performance, eliminates bottlenecks resulting from the explosion of data volume, frees-up server and user-level bandwidth, boosts application response, and significantly improves data backup times. Xframe E is fully compliant with both the PCIe 1.1 specification and the IEEE 802.3ae 10 Gigabit Ethernet standard. The adapter connects to the host system using a PCIe x4 connector. On the network side, Xframe E utilizes industry-standard SR and LR optical transponders. All Xframe products include full IPv4 and IPv6 support, combined with comprehensive stateless offloads that preserve the integrity of current TCP/IP implementations without “breaking the stack.” Xframe drivers are available for all major Operating Systems, including Microsoft Windows, Linux (included in the kernel), Hewlett-Packard HP-UX, IBM AIX, Sun Solaris and SGI Irix. All Neterion products are designed to be fully software forward-compatible with future releases.


Xframe E is based on a sophisticated ASIC state machine architecture with built-in HA/RAS (High Availability/Reliability, Availability, Serviceability) features that provide the highest performance and reliability available.
