Dual-Port 10GbE Converged Adapter
The Dell T520-CR is a dual-port 10GbE converged network adapter built on a Chelsio T5 ASIC. It connects through a PCI Express 3.0 x8 slot and carries a Dell part number of PDHV4. The card presents two SFP+ ports for fibre or direct-attach cables. It is supplied new in a green PCB finish.
Suits servers needing unified wire offload
This adapter suits administrators who want iSCSI, FCoE and TCP/IP handled on a single card with hardware offload to reduce CPU load. It fits servers that expose a PCI Express 3.0 x8 slot and run Linux, Windows Server or VMware. Builders without an x8 slot or without SFP+ cabling should consider other connectivity options.
PCI Express 3.0 x8 interface requirement
The single specification that decides fitment is the PCI Express 3.0 x8 interface. The board requires a physical and electrical x8 slot operating at Gen 3 speed. Without that slot the adapter cannot be installed or will fall back to lower bandwidth. Verify the server backplane and riser layout before ordering.

Questions about this item
Does my server have the PCI Express 3.0 x8 slot this T520-CR requires?
The adapter fits any server with a PCI Express 3.0 x8 slot. Verify your system board or riser provides that physical and electrical connection before purchase.
Will the dual 10GbE SFP+ ports link at full speed with my existing 1 GbE switch?
The SFP+ ports negotiate down to 1 GbE when connected to slower switches, so legacy cabling and switches remain usable while the adapter is ready for future 10 GbE upgrades.
How can I confirm the Chelsio T5 ASIC is offloading traffic after driver installation?
Check the adapter statistics in the OS network panel or Chelsio utilities; offloaded iSCSI, FCoE or TCP/IP sessions will show reduced CPU utilisation and hardware counters incrementing for those protocols.
