2-Ports Small Form-Factor Pluggable Plus (SFP+)

The HPE 727055-B21 is equipped with two Small Form-Factor Pluggable Plus (SFP+) ports. SFP+ is a compact, hot-pluggable transceiver used for high-speed communication in networking equipment. These ports support a variety of SFP+ modules, allowing flexibility in network configurations. The HPE 727055-B21 network adapter utilizes the Small Form-Factor Pluggable Plus (SFP+) technology. SFP+ is an enhanced version of the original SFP transceiver, specifically designed to support higher data rates. This compact and hot-swappable optical transceiver form factor allows for flexibility in network configurations and simplifies the process of upgrading or replacing network components.

10 Gigabits Per Second (Gbps) Data Transfer Rate

One of the standout features of the HPE 727055-B21 is its impressive 10 Gbps data transfer rate. This high-speed capability is essential for demanding enterprise applications, such as data-intensive tasks, high-performance computing, and large-scale data transfers. The 10 Gbps speed ensures efficient and rapid data communication across the network.

10GBase-X Gigabit Ethernet

The adapter supports 10GBase-X Gigabit Ethernet, a standard that defines the specifications for 10 Gbps Ethernet over optical fiber or copper cabling. This Gigabit Ethernet variant is well-suited for modern data centers and enterprise networks, providing a balance of speed and reliability. With a staggering data transfer rate of 10 Gigabits per second, the HPE 727055-B21 ensures that data can move swiftly and efficiently across the network. This high-speed capability is particularly crucial for modern applications and workflows that demand rapid data access and transmission.

PCI Express Compatibility

The HPE 727055-B21 utilizes the PCI-E 3.0 x8 interface. Before installation, it is essential to ensure compatibility with the server or workstation's available PCI Express slots. Most modern servers and workstations support PCI Express 3.0, but verifying compatibility is crucial for optimal performance. The HPE 727055-B21 network adapter is equipped with a Peripheral Component Interconnect Express (PCI-E) 3.0 x8 interface. PCI-E is a high-speed serial computer expansion bus standard that provides a fast and efficient connection between the network adapter and the server's motherboard. The x8 designation indicates the number of lanes or channels available for data transmission, with x8 providing significant bandwidth to support the adapter's 10 Gigabits per second capabilities.


With two SFP+ ports, the adapter allows for scalability in network design. Organizations can easily scale their network infrastructure by adding more adapters or connecting to additional enabled devices, providing flexibility for future growth. The SFP+ technology employed by the HPE 727055-B21 adds a layer of scalability and flexibility to network design. The small form factor of the SFP+ transceiver allows for efficient use of space within networking equipment. Additionally, the hot-swappable nature of SFP+ modules enables network administrators to make changes or upgrades without disrupting the entire network, contributing to increased scalability and flexibility.

Versatility in Connectivity

The support for 10GBase-X Gigabit Ethernet and SFP+ modules enhances the adapter's versatility in connectivity options. Whether connecting through optical fiber or copper cabling, the HPE 727055-B21 adapts to various network environments, offering a broad range of deployment possibilities.

High Performance

The 727055-B21 HPE 10GbE 2-Ports PCIE SFP+ Ethernet Adapter is a high-performance network adapter designed for use with HPE servers. It is a PCI Express (PCIe) based adapter that provides two 10 Gigabit Ethernet (10GbE) ports, allowing for high-speed data transfer between servers and other network devices.

This adapter uses Small Form-Factor pluggable (SFP+) transceivers, which are small, high-speed, and low-power devices that plug into the adapter and provide the 10GbE connection. This allows for easy and flexible connectivity options, as different types of SFP+ transceivers can be used to connect to various types of network devices.

The adapter also features advanced features such as support for hardware offloads, which can improve performance and reduce CPU utilization, as well as support for various network protocols and standards, such as TCP/IP, iSCSI, and Fibre Channel over Ethernet (FCoE).

Resiliency and High Availability

The HPE 10GbE 2-Ports PCIE SFP+ Ethernet Adapter (part number 727055-B21) is a high-performance networking adapter that is designed for resiliency and high availability in enterprise environments.

Resiliency refers to the ability of the adapter to continue functioning in the event of a failure or interruption. This can be achieved through a number of features such as redundant power supplies, hot-swappable components, and link aggregation (which allows multiple network connections to be combined into a single, high-speed link).

High availability refers to the ability of the adapter to provide uninterrupted service even in the event of a failure. This can be achieved through features such as failover and load balancing, which allow the adapter to automatically switch to a backup connection in the event of a failure.

The HPE 10GbE 2-Ports PCIE SFP+ Ethernet Adapter is designed to provide both resiliency and high availability to ensure that network connections are always available and functioning at optimal speeds.
