Xframe II - 10 Gigabit Ethernet PCI-X 2.0 Server & Storage Adapter

Xframe II

Xframe II is a 10 Gigabit Ethernet adapter taking advantage of the PCI-X 2.0 bus architecture. It doubles the data rate delivered by the earlier bus standard (PCI-X 1.0) and unleashes the full line speed of 10 Gb/sec. It allows data center managers faced with exponentially increasing bandwidth needs to boost their network’s performance while preserving their investment in Ethernet.

Capitalizing on Ethernet, the proven industry-standard for 30 years, the Xframe II 10 Gigabit Ethernet Adapter allows end-users to preserve their existing environment: operating systems, network administration tools, core cabling, personnel training, etc. Xframe II dramatically increases network performance, eliminates bottlenecks resulting from the explosion of data volumes, frees-up server and user-level bandwidth, boosts application response and slashes data backup times. Xframe II is fully compliant with the PCI-X 2.0 Mode II specification and the IEEE 802.3ae 10 Gigabit Ethernet standard. The Xframe II host system interface is a 64-bit, 133 MHz (DDR) capable PCI-X bus. The Xframe network interface is a 10 Gigabit Ethernet link, using standardized PMD (Physical Media Dependent) devices to ensure ready interoperability. All Xframe products include full IPv4 and IPv6 support, and 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’s HP-UX, IBM’s AIX, Sun’s Solaris and SGI’s Irix. All Neterion products are designed to be fully software forward-compatible with future releases.


Xframe II is based on a sophisticated state machine architecture with built-in HA/RAS features that provide the highest performance and reliability available.

  • Extensive Protocol Offloads and Assists maximize host efficiencies by reducing host processing loads, and optimizing bus utilization
  • “Deep-Split Bus Transaction Capacity” provides full utilization of PCI-X bus while achieving the industry’s lowest latency
  • Flexible Interrupt Features include INTA, PCI 2.2 Message Signaled Interrupt (MSI), and next generation MSI-X
  • True QoS (Quality of Service) support for up to 8 levels in both directions, allowing traffic to be classified, prioritized, and queued at line rate
  • 32 MB of on-board memory drastically reduces performance-degrading link-layer flow control
  • Turn-key driver support for all major Operating Systems and server architectures (Custom driver development is available)
  • ECC (SEC/DED) protection for all PCI-X Mode II bus transactions and on-board data and control structures
  • “Carrier Grade” environs for power, thermal, and noise characteristics
  • Modular design permits various connectivity options, including Short Reach optical (SR), Long Reach optical (LR), and CX-4 (copper)
