Product BriefMarvell® FastLinQ® 57840S10Gbps Quad-Port iSCSI, FCoE, and TOE PCI-SIG SR-IOV x8 PCI Express® 3.0 ConvergedController
The Marvell FastLinQ 57840S Converged Controller is a sixth-generation convergedcontroller designed for high-volume, converged LAN on motherboard (LOM) andConverged Network Adapter applications. The controller enables PCI-SIG single root
input/output virtualization (SR-IOV), iSCSI, Fibre Channel over Ethernet (FCoE), data
center bridging (DCB), and on-chip TCP/IP offload engine (TOE). The converged controller supports PCI Express (PCIe®) 3.0, along with embedded virtual bridging and otherswitching technologies for high-performance DMA and virtual machine (VM)-to-VMswitching.

The Marvell FastLinQ 57840S Controller includes quad-channel 10GBASE-KR andSFF-8431 for SFP+ 10Gb and SFP 1Gb interfaces. The 57840S Controller integrates four
IEEE 802.3™-compliant MACs and supports the network controller-sideband interface(NC-SI). Host-BMC communication is also supported on top of NC-SI to permit highspeed communication between the local host and the baseboard management
controller (BMC) or management controller (MC). The feature-complete convergedcontroller requires only 0.82 square inches of printed circuit board (PCB) space andenables 10G speeds at low per-port power.
For more effective use of 10GbE bandwidth, the Marvell FastLinQ 57840S Controller
offers Marvell switch-independent NIC partitioning (NPAR), which enables the segmentation of a single port into two virtual ports (in 4 × 10G mode) or four virtual ports (in2 × 10G or 2 × 20G modes) with flexible bandwidth allocation to each partition. Thesegmentation allows IT organizations to improve resource usage while lowering
infrastructure and operational costs.
The 57840S Controller enables convergence of all possible network communications in
a server, such as data network (LAN), FCoE storage network or block (for example, iSCSI).
The Marvell FastLinQ 57840S Controller can simultaneously support all offload traffic
types on each of the ports, including simultaneous iSCSI and FCoE. Offload results insuperior storage and networking performance, as well as low CPU usage, which resultsin significant system-level power savings.
The Marvell FastLinQ 57840S Controller is designed for PCIe 3.0 and is also compatible
with PCI Express Base Specification, revisions 2.0 and 1.1. PCI Express supports MSI andMSI-X capabilities. A separate PCI function is supported for each of the ports.
