IBM QLOGIC CNA 10GB FOR SYSTEM x

The QLogic 10Gb CNA is a PCI Express 2.0 x4 10Gb Converged Network Adapter and is available for both IBM System x and IBM Power Systems servers. For IBM Power Systems, the adapter is known as the 10 Gb FCoE PCIe Dual Port Adapter (Feature 5708). The adapter connects to SFP+ Multimode Fiber SR optical modules. The System x version also supports SFP+ Active Copper cables, depending on the Ethernet switch used.

This adapter supports 10 Gbps per port maximum bidirectional throughput for high-bandwidth storage (SAN) and networking (LAN) traffic, with full hardware offload for Fibre Channel over Ethernet (FCoE) protocol processing.

The QLogic 10Gb CNA has the following features:

- PCI Express 2.0 compliance.
- Operates at PCI Express 2.0 x4 or PCI Express 1.1 x8.
- Transceiver support: System x option: Two SFP+ cages for either SFP+ Fiber SR or SFP+ Active Copper; Power Systems feature: Two QLogic 10Gb SFP+ SR Optical Transceivers standard.
- Standard PCI Express half length card with low profile form factor.
- Support for both standard PCI-E slot and low profile PCI-E slot (System x option only).
- Support for 10Gb Converged Enhanced Ethernet (CEE).
- Support for Fibre Channel over Converged Enhanced Ethernet (FCoCEE).
- Full hardware offload for FC protocol processing.
- Support for IPv4 and IPv6.
- Support for SAN boot over CEE and iSCSI boot.
