## Long description

Chelsio T540-LP-CR is a low-profile 4-port network adapter with SFP+ connectors that provides 1/10GbE connectivity for servers and workstations. The card uses a PCI Express x8 Gen3 interface and is engineered to support high-density virtualized and storage networking environments. With capabilities to manage up to 32,000 simultaneous connections, the adapter addresses requirements for low-latency packet processing, multi-tenant deployments and reliable 10GbE links in constrained form-factor systems.
Advantages
The adapter combines four SFP+ ports with a low-profile design to fit compact server and workstation chassis while offering 1/10GbE performance. The PCIe x8 Gen3 interface provides sufficient bandwidth for aggregated 10GbE traffic. Support for up to 32K connections enables large numbers of concurrent sessions typical of virtualization, storage networks and multi-tenant services. The design emphasizes low latency and reliable packet handling suitable for demanding network I/O.
Suitable for
 Virtualized server environments with high session density
 Storage networks requiring 10GbE links
 Multi-tenant hosting and cloud infrastructure
 Workstations and compact servers with low-profile PCIe slots
 Applications requiring low-latency packet processing
Key specifications
 Form factor: low-profile network adapter
 Ports: 4 × SFP+ supporting 1GbE and 10GbE optics
 Interface: PCI Express x8 Gen3
 Connection capacity: up to 32,000 simultaneous connections
 Performance focus: low-latency packet processing and high-density session handling
How to use
Install the Chelsio T540-LP-CR into an available low-profile PCIe x8 (or higher) slot on a compatible server or workstation. Populate the SFP+ ports with appropriate 1GbE or 10GbE SFP/SFP+ modules or DAC/optical cables, and connect to the network or storage fabric. Ensure the host operating system has the appropriate Chelsio drivers and firmware installed and configured; follow standard procedures for assigning network interfaces, configuring link speed and enabling any vendor-provided offload or virtualization features as required.
Usage recommendations
For optimal results, use certified SFP+ modules or cables that match your network infrastructure and verify firmware/drivers are up to date. In virtualized or multi-tenant deployments, allocate sufficient host resources and leverage the adapter's connection capacity to balance sessions across ports. Monitor link status and throughput after installation to confirm expected 1/10GbE performance and low-latency behavior.
