Enhanced Network Connectivity

The HPE B22 Fabric Extender offers enhanced network connectivity capabilities that allow for improved performance and scalability. This device can extend the capabilities of HPE BladeSystem c-Class switches by providing additional uplink ports and reducing the amount of cabling required in the data center.

The B22 Fabric Extender connects to the BladeSystem c-Class switch through a high-speed 10 Gigabit Ethernet connection, providing an additional 16 downlink ports that can be used to connect to servers, storage devices, and other network devices. This improves network connectivity and helps reduce latency and bottlenecks, allowing for faster and more reliable data transfers.

In addition, the B22 Fabric Extender is designed to support a variety of network protocols and topologies, including Ethernet, Fibre Channel, and Virtual Extensible LAN (VXLAN). This makes it a flexible and adaptable solution for a wide range of data center environments.

Scalability and Flexibility

Scalability and flexibility are essential for any networking product, as they allow organizations to easily adapt to changing business needs and growing network demands. The HPE B22 Fabric Extender is designed to provide excellent scalability and flexibility to meet the needs of modern enterprise networks.

One of the key features that enable scalability in the HPE B22 Fabric Extender is its modular design. The product is designed to work with HPE BladeSystem c-Class enclosures, and it can be easily expanded by adding additional modules to the enclosure. This modular design allows organizations to quickly and easily add new network capacity as needed, without having to replace existing hardware.

The HPE B22 Fabric Extender also supports a range of networking protocols and standards, including 10 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE), and Data Center Bridging (DCB). This means that organizations can use the product to support a wide range of network configurations, including virtualized environments and converged network environments.

In addition to its modular design and support for multiple networking protocols, the HPE B22 Fabric Extender also offers excellent flexibility. The product includes a range of features that make it easy to manage and configure, including an embedded web interface and support for common network management tools like Simple Network Management Protocol (SNMP).

The HPE B22 Fabric Extender also supports Virtual Extensible LAN (VXLAN) technology, which allows organizations to create virtual networks that span across multiple physical network segments. This feature is especially useful for organizations that need to create complex network topologies or segment their networks to improve performance or security.

Simplified Network Management

The HPE B22 Fabric Extender offers simplified network management by providing a unified management platform that can be used to manage both the fabric extender and the upstream switch as a single entity. This simplifies management by reducing the number of management points and simplifying troubleshooting.

The HPE B22 Fabric Extender is also designed to be easy to install and configure. It can be quickly deployed using HPE SmartStart, which is a simple, easy-to-use software tool that automates many of the configuration tasks required to deploy the fabric extender.

In addition, the HPE B22 Fabric Extender provides support for standards-based management protocols such as SNMP, allowing it to be easily integrated into existing management systems. This simplifies the process of managing the fabric extender and allows it to be easily monitored and managed along with other network devices.
