Introduction and Overview
The BK835A HPE 1Cn1100e 10 GBe Sfp 2Port Converged Network Adapter is a network interface card designed for high-performance computing and data center environments. It is manufactured by Hewlett Packard Enterprise (HPE) and is part of their HPE Converged Network Adapter (CNA) product line.
The BK835A adapter supports two 10 Gigabit Ethernet (10 GbE) ports, each of which can be configured with either a copper or fiber Small Form-Factor Pluggable (SFP) transceiver module. This flexibility allows the adapter to support a variety of different network topologies, including both copper and fiber-based connections.
The adapter also supports Data Center Bridging (DCB) and Fibre Channel over Ethernet (FCoE) protocols, which enable it to provide converged networking capabilities. DCB allows for the prioritization of different types of network traffic, while FCoE allows for the transport of Fibre Channel storage traffic over Ethernet networks.
The BK835A adapter is designed to be installed in a server's PCI Express (PCIe) expansion slot and is compatible with a variety of different server platforms from HPE and other vendors. Once installed, the adapter can provide high-speed connectivity to the server, enabling it to support demanding applications and workloads.
Design and Dimensions
The BK835A HPE 1Cn1100e 10 GBe Sfp 2Port Converged Network Adapter is a high-performance network interface card designed for HPE ProLiant servers. This adapter is designed to support both Ethernet and Fibre Channel traffic over a single network connection, making it a useful tool for organizations looking to consolidate their networking infrastructure.
The adapter features two SFP+ ports, which can be used to connect to either Ethernet or Fibre Channel networks. These ports support 10 Gigabit Ethernet speeds, allowing for high-speed data transfers between the server and the network. The adapter also supports RDMA (Remote Direct Memory Access) technology, which enables low-latency data transfers over the network.
In terms of dimensions, the BK835A HPE 1Cn1100e 10 GBe Sfp 2Port Converged Network Adapter measures 6.6 x 2.7 x 0.7 inches (16.76 x 6.86 x 1.78 cm) and weighs approximately 0.2 lbs (0.09 kg). This makes it a compact and lightweight device that can easily fit into the server's PCIe slot. The adapter is compatible with HPE ProLiant Gen9 and Gen10 servers and can be installed in either a low-profile or full-height PCIe slot.
Compatibility and Operating Systems
The BK835A HPE 1Cn1100e 10 GBe Sfp 2Port Converged Network Adapter is a high-performance network interface card (NIC) designed for use in HPE (Hewlett Packard Enterprise) servers and storage systems. It is designed to provide high-speed network connectivity for converged applications, combining data, storage, and management traffic onto a single network fabric.
In terms of compatibility, the BK835A is designed to work with a range of HPE servers and storage systems, including HPE ProLiant DL and ML servers, HPE BladeSystem c-Class enclosures, and HPE StoreVirtual storage systems. To ensure compatibility, it's recommended to check the HPE server and storage system compatibility matrix before purchasing the adapter.
In terms of operating system support, the BK835A is compatible with a range of operating systems, including:
- Microsoft Windows Server 2012 and later versions
- Red Hat Enterprise Linux 6 and later versions
- SUSE Linux Enterprise Server 11 and later versions
- VMware ESXi 5.x and later versions
It's important to note that specific driver versions may be required for each operating system, and these can be obtained from the HPE website.

A converged adapter is also referred to as a converged network adapter (CNA) or a single network interface card (NIC). Within a network, the CNA serves the combined roles of a fiber channel host bus adapter and TCP/IP Ethernet network interface card.
The role of a converged adapter is to connect servers to FC-based SANs and Ethernet-based LANs, including workstations and other hardware units. The adapter connects to the server through the PCI-e interface. Therefore, the server will send fiber channel SAN and Ethernet-based LAN to the Ethernet port on the converged adapter through the Fiber Channel over Ethernet protocol for FC-based SAN data and Ethernet protocol for traffic and data on LAN.
At the CNA level, FCoE traffic is first converted into FC and then sent to the FC-based SAN. There's no conversion for Ethernet traffic, which is directly sent to a LAN. Where a CNA is absent, servers must have at the very least two adapters. The first is an FC HBA adapter that aids in connecting the server to SAN, while the second will have a TCP/IP Ethernet NIC that facilitates the connection to the LAN.
We have a wide range of converged network adapters that will come in handy in meeting the requirements of your computer network. The use of a CNA to make the connection between servers to both SAN and LAN helps to reduce costs since it will cut back on the number of adapter cards, PCI-e slots, cables, and switch ports used within the network. As a result, a converged adapter will greatly minimize the challenge of network maintenance and administration, since there will be only a single connection and a single cable to look after.
Other benefits of converged adapters and converged networks are:
- Simplification of the typical storage and network topology
- Access to basic network interface card features and performance virtualization over NIC.
- All-in-one provision of Ethernet, iSCSI, and Fiber Channel (FC) connectivity by offloading FCoE and iSCSI hardware.
- Guaranteed data integrity
- Power saving because of fewer adapters and cables.
- Minimal impact of the overlay network
- Fewer switch ports - 1 Port, 2 Port, 4 Port
- Lower cabling requirements
- Centralized network management
- Improved quality of service
- Remote direct memory access to facilitate data acceleration
- Support for software-defined networking (SDN) programming
Converged network adapter plays a strategic role within networks and many IT setups in that they help business owners and network admins consolidate their systems, harness new and emerging technologies, and ensure efficient IT operations. CNAs will also serve as a foundation for all-inclusive progress to more powerful and sophisticated computing networks and systems. With the increased sophistication in storage, handling, and evaluation of data, CNAs as well as other network admin tools are changing the network landscape and creating intelligent and capable networks.
Besides, the converged adapters can be used with specific hardware pieces that can be used to satisfy performance standards. A CNA can be used alongside 10 Gigabit and 40 Gigabit to support greater performance network transmission.
