Description
Product Overview
The Dell 540-BBQR Dual-port 25GbE SFP28 Full Height Network Adapter is a high-performance networking component designed for use in enterprise environments. This network adapter is capable of providing two 25GbE SFP28 ports that are ideal for data centers, cloud environments, and other high-bandwidth applications.
Key Features
The Dell 540-BBQR Dual-port 25GbE SFP28 Full Height Network Adapter is a PCIe Gen3 x8 network interface card that supports two 25GbE SFP28 ports. The SFP28 ports are compatible with both 10GbE and 25GbE SFP28 transceivers, providing flexibility for a range of connectivity options. The adapter supports full hardware offload for TCP/IP and iSCSI protocols, which can reduce CPU utilization and improve overall network performance.
One notable feature of the Dell 540-BBQR is its support for Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE). RDMA is a network technology that allows data to be transferred directly between the memory of two systems, bypassing the CPU and improving performance. RoCE is a protocol that enables RDMA over Ethernet networks. This feature can significantly reduce latency and improve network throughput, making it ideal for high-performance computing applications.
Another important feature of the Dell 540-BBQR is its support for network virtualization technologies such as VMware NSX and Microsoft Hyper-V Network Virtualization (HNV). These technologies enable the creation of virtual networks that can be isolated from each other and provide increased security and flexibility. The adapter also supports Single Root I/O Virtualization (SR-IOV), which allows a single physical network adapter to be partitioned into multiple virtual network adapters.
Benefits of Network Adapter
The Dell 540-BBQR Dual-port 25GbE SFP28 Full Height Network Adapter provides several benefits to enterprise environments. One of the main benefits is increased network performance. The 25GbE SFP28 ports offer high bandwidth and low latency, which can improve application performance and reduce network congestion. The full hardware offload for TCP/IP and iSCSI protocols can also reduce CPU utilization and improve overall network performance.
The support for RDMA over RoCE can further improve network performance by reducing latency and improving throughput. This feature is particularly useful in high-performance computing environments where large amounts of data need to be transferred quickly between systems.
The support for network virtualization technologies such as VMware NSX and Microsoft HNV can provide increased security and flexibility. These technologies allow virtual networks to be created and isolated from each other, providing additional layers of security. SR-IOV support can also enable the creation of multiple virtual network adapters from a single physical network adapter, allowing for more efficient use of network resources.
Compatibility
The Dell 540-BBQR Dual-port 25GbE SFP28 Full Height Network Adapter is compatible with a range of Dell systems, including PowerEdge R740, R740XD, R640, R940, R7425, and R7525 servers. It is also compatible with PowerEdge C6420, FC640, M640, MX740c, and MX840c servers.
To ensure compatibility, it is important to check the system specifications and verify that the adapter is supported. Dell also provides a compatibility matrix that lists all supported systems and their corresponding network adapters.
In summary, the Dell 540-BBQR Dual-port 25GbE SFP28 Full Height Network Adapter is a high-performance networking component designed for use in enterprise environments.
