FastLinQ® 1000 Series CNA
The Cavium™ FastLinQ® BR-1020 dual-port Converged Network Adapter (CNA) integrates 10Gbps Ethernet Network Interface Card (NIC) functionality with Fibre Channel technology—enabling transport over a 10 Gigabit Ethernet (GbE) connection through the new Data Center Bridging (DCB) and Fibre Channel over Ethernet (FCoE) protocols, providing best-in-class LAN connectivity and I/O consolidation to help reduce cost and complexity in next-generation data center environments.
OverviewToday's IT professionals face the difficult challenge of reducing data center cost and complexity while satisfying numerous service-level agreements (SLAs) and performance requirements. As a result, organizations are seeking ways to improve server and storage utilization, reduce ongoing operational costs, and increase their flexibility and responsiveness.
Improved TCO through I/O Consolidation
DCB is a new set of industry standards that enhances the Ethernet protocol to enable low-latency, lossless, and deterministic network infrastructure for storage and other highly demanding traffic types. Cavium CNAs support all of these standards, including priority-based flow control (PFC), enhanced transmission selection (ETS), congestion notification (CN), and Data Center Bridging Exchange (DCBX).
FCoE encapsulates and transmits Fibre Channel frames over this enhanced Ethernet infrastructure while preserving the Fibre Channel constructs and management paradigm for backward compatibility and investment protection.
By leveraging these technologies, Cavium CNAs enable organizations to consolidate multiple 1 GbE NICs and Fibre Channel host bus adapters (HBAs) into a single adapter. Cavium CNAs provide a powerful 10Gbps solution that helps consolidate both TCP/IP and storage (iSCSI/FC) traffic over a single link. This helps significantly reduce server deployment costs, as well as power and cooling requirements, delivering best-in-class LAN and SAN connectivity while reducing total cost of ownership (TCO).
Cavium CNAs enable virtual machine (VM) discovery in VMware ESX environments within Cavium DCFM. VM discovery provides an end-to-end view of the VM-to-LUN path information for all the VMs running on each physical server. This provides unprecedented levels of visibility into the virtual server infrastructure, enabling network administrators to more efficiently manage their storage network resources.
For simple device configuration, driver updates, or to obtain CNA and port statistics, a graphical user interface (GUI) element manager—Cavium Host Connectivity Manager (HCM)—and a command line interface (CLI) are also available. Both Cavium DCFM and HCM provide open APIs and standards-based interfaces for integration with popular third-party applications and higher-level frameworks to help orchestrate network services.
The 1000 Series adapter integrates with Brocade® Network Advisor to help simplify SAN and LAN management.
The explosive growth of server virtualization and high-bandwidth applications, such as video-on-demand and high-performance computing (HPC), are leading to increased performance demands, making 10Gbps connectivity a key requirement. Recent advances in server technology, including Intel Romley processors, now enable servers to run more workloads, increasing consolidation and virtualization ratios. With more VMs deployed per server, network bandwidth and storage I/O requirements are higher than ever before.
Cavium CNAs are fully featured 10 GbE NICs that deliver 10Gbps line rate performance per port. They provide stateless networking offloads such as TCP checksum and segmentation offloads for improved performance and more efficient CPU usage. Additional CPU cycles can then be dedicated for additional application processing.
Cavium CNAs deliver full hardware-based FCoE offload to provide superior performance for storage applications.
Ultimately, this means that businesses of all sizes can scale their virtual server deployments and virtualize highly demanding applications with greater confidence, resulting in better server resource utilization and lower capital and operational costs.
Optimized for Virtual Environments
In non-virtualized environments, applications are tied to physical servers, which in turn connect to physical switch ports in a "static" manner. Applying network policies or monitoring application performance is simple because the applications are permanently associated with the physical ports.
With server virtualization, multiple applications share a physical switch port. Furthermore, applications can move across the virtualized server infrastructure based on a number of user-defined policies and in response to dynamic business requirements. Virtualization hypervisors implement virtual switching technologies to connect the VMs to the network, and to move data between VMs.
Virtual Machine Optimized Ports (VMOPs) offload the hypervisor of essential virtual switching tasks, such as incoming packet classification and sorting tasks, helping to reduce latency and improve throughput while freeing CPU cycles that can be used to further scale an organization's virtualization environment.
Cavium CNAs support N_Port ID Virtualization (NPIV) with up to 255 virtual ports, and are qualified with all major hypervisor solutions in the industry. Leveraging NPIV technology, organizations can extend Cavium fabric services to the server and all the way to the VM and application level.
