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.
