Network adapters
x3750 M4 supports two integrated Gigabit Ethernet ports. Optionally, two 10 Gb Ethernet ports can be
added by installing one of the available dual-port 10 Gb Ethernet cards listed in Table 12 (88Y7429 or
88Y7427). These cards use a dedicated connector on the system board and do not consume a PCI
expansion slot. The onboard Emulex BE3 controller provides both the Gigabit Ethernet ports and the 10
Gb Ethernet ports. The optional cards are used route the ports to external RJ45 or SFP+ ports.
The integrated controller has the following features:
Emulex BE3 chip
Two Gigabit Ethernet ports and two 10 Gb Ethernet ports with optional adapter (1 Gb and 10 Gb
auto-negotiation)
Full-duplex (FDX) capability
Supports IPv6
Optional 10 Gb ports that operate in either a virtual NIC (vNIC) or physical NIC (pNIC) mode:
vNIC mode: Up to six vNICs (up to three vNICs per one 10 Gb port):
Virtual Fabric mode or Switch Independent operational mode
Virtual port bandwidth allocation in 100 Mbps increments
Up to two vNICs can be configured as an iSCSI or FCoE vNICs (one per port) with optional
Advanced Upgrade (90Y9310)
pNIC mode: Dual-port 1/10 Gb Ethernet adapter
IEEE 802.1Q VLAN tagging
VLAN insertion and extraction
Jumbo frames up to 9000 bytes.
Load balancing and failover teaming support, including adapter fault tolerance (AFT), switch fault
tolerance (SFT), adaptive load balancing (ALB), and IEEE 802.3ad
Supports Serial over LAN (SoL) and concurrent KVM (cKVM)
Wake On LAN support (1 Gb ports only)
Message Signal Interrupt (MSI-X) support
IPv4/IPv6 offload:
IPv4 TCP Chimney Offload
TCP, UDP checksum offload
Large send offload (LSO)
Large receive offload (LRO)
Receive side scaling (RSS)
Enhanced Ethernet (draft) support:
Enhanced Transmission Selection (ETS) (P802.1Qaz)
Priority-based Flow Control (PFC) (P802.1Qbb)
Data Center Bridging eXchange Protocol (DCBX) (P802.1Qaz)
