Network adapters
The HS23 offers two integrated Gigabit Ethernet ports and two integrated 10 Gb Ethernet ports with the
integrated Emulex BladeEngine 3 (BE3) controller. Two Gigabit Ethernet ports are routed to the chassis
I/O bays 1 and 2, and two 10 Gb Ethernet ports are routed to the chassis I/O bays 7 and 9 using either
10Gb LOM Interposer Card or Emulex Virtual Fabric Adapter II for HS23.
The integrated BE3 4-port NIC has the following features:
Two Gigabit Ethernet ports and two 10 Gb Ethernet ports (1 Gb and 10 Gb auto-negotiation).
Full-duplex (FDX) capability.
10 Gb ports 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
IPv4/IPv6 offload:
TCP, UDP checksum offload
Large send offload (LSO)
Large receive offload (LRO)
Receive side scaling (RSS)
IPv4 TCP Chimney Offload.
