Enterprise-class blade server connectivity for next-generation virtualized data centers

Enterprise-class blade server connectivity for next-generation virtualized data centers

Help reduce cost and complexity in next-generation data center environments with the Brocade BR1741M-k CNA for Dell PowerEdge M-Series blade servers. It’s a powerful dual-port 10GbE network interface card (NIC) that supports DCB and FCoE standards to deliver enterprise-class local area network (LAN) connectivity and server I/O (input/output) consolidation.

  • High-performance line-rate 10GbE for reliable, enterprise-class LAN connectivity for Dell blade servers
  • DCB support for low-latency, lossless and deterministic 10GbE connectivity and storage over Ethernet applications (FCoE/Internet SCSI [iSCSI])
  • Advanced Ethernet performance, including IP version 4 (IPv4) and IP version 6 (IPv6) checksum offload, Receive Side Scaling (RSS), Header Data Split (HDS), jumbo frame support and TCP Segmentation Offload (TSO)
  • Scalable connectivity features, including virtual switching offloads, across a secure, multiprotocol lossless environment
  • Unified Fibre Channel, FCoE and Ethernet driver stack that enables a single driver for both Brocade CNAs and Fibre Channel host bus adapters (HBAs)

Improved TCO through I/O consolidation

The Brocade BR1741M-k CNA leverages DCB and FCoE technologies to help you consolidate 1/10 GbE NIC and Fibre Channel HBA mezzanine cards into a single adapter and to transport both TCP/IP and storage (iSCSI/FC) traffic over a common link.

DCB is a new set of standards that is designed to enhance the widely adopted Ethernet protocol to deliver a low-latency, lossless and deterministic network infrastructure for storage and other highly demanding traffic types. FCoE encapsulates Fibre Channel frames and transmits them over this enhanced Ethernet infrastructure while preserving the Fibre Channel constructs and management paradigm.

This I/O consolidation helps dramatically reduce blade server deployment costs as well as power and cooling requirements, delivering best-in-class connectivity while reducing total cost of ownership (TCO).
Unmatched performance

Unmatched performance

With the recent advances in server technology, servers are capable of running more workloads than ever. This drives higher consolidation and virtualization ratios and unprecedented I/O requirements.

The Brocade BR1741M-k CNA is a full-featured 10GbE NIC delivering full 10 Gbps line-rate performance on both ports. It provides industry-standard stateless networking offloads, such as TCP checksum and segmentation offloads, to improve performance and reduce CPU loads, enabling them to dedicate more resources to application processing.

In addition, the Brocade CNA delivers full hardware-based FCoE offload to provide superior performance for storage applications, delivering up to twice the performance of competing products in real-world application scenarios.

Optimized for virtual environments

The Brocade BR1741M-k CNA supports NPIV with up to 255 virtual ports, and it’s qualified with all major hypervisor solutions in the industry. Leveraging NPIV technology, you can not only extend Brocade fabric services to the server but also to the VM and application level. 

Virtual Machine Optimized Ports (VMOP) is a feature that offloads essential packet classification tasks from the hypervisor, reducing latency and improving throughput while freeing CPU cycles that can be used to further scale an organization’s virtualization environment.
