Emulex OneConnect is a universal CNA that supports 10 Gigabit Ethernet (10GbE) networking with high-performance CPU offloads for fiber channel over Ethernet (FCoE), iSCSI, stateless TCP/IP and TCP Offload Engine (TOE) with a single-chip, multi-function adapter. OneConnect is a family of products that are all based on a common architecture. The payoff is a single framework for all 10GbE connectivity with simplified version management and testing. With OneConnect, you can choose a specific product that has the appropriate support for networking and storage. That decision is then future-proofed with the option to reconfigure the same physical adapter to support a different set of protocols if requirements change.
Single 10GbE architecture and strategy
OneConnect is a family of products that are all based on a common architecture. The payoff is a single framework for all 10GbE connectivity with simplified version management and testing.
Lower operating temperature
OneConnect UCNAs operate 43°F cooler than the QLogic QLE8100 CNA. The figure below shows thermal "hot spots" on the QLE8100 with temperatures detected near the 212°F maximum where immediate component failure can occur. Lower operating temperatures result in greater reliability for the adapter and other components in the server.
The quantum leap to 10GbE bandwidth makes iSCSI a more viable option for data center deployments. Although QLogic sells an older 1GB iSCSI adapter, they are not supporting iSCSI offload with any of their 10GB products. QLogic support for 10GB iSCSI is based on software initiators that use CPU resources for I/O processing, reducing virtualization ratios and slowing compute-intensive applications.
TOE/TCP chimney offload
TCP Offload Engine (TOE) is a proven technology that is supported by Windows Server 2003 and Windows Server 2008 as TCP chimney offload. TCP chimney offload is particularly well suited for long-lived connections and large packet payloads, which are closely aligned with applications like streaming media that are driving demand for 10GE bandwidth.
OneCommand Manager applicationProduct Highlights
The OneCommand Manager application enables management of Emulex One Connect UCNAs and LightPulse HBAs and CNAs throughout the data center from a centralized console. Administrators can manage high-performance connections for networking and storage with a single view of the entire network.
- Higher server virtualization ratios
- Greener" data centers that use less power and cooling
- Better performance for compute-intensive applications
- Lower operating temperature, greater reliability
