The expansion blade provides the capability to attach selected PCI Express cards to the HS23. This

capability is ideal for many applications that require special telecommunications network interfaces or

hardware acceleration using a PCI Express card. The expansion blade provides one full-height and full-

length PCI Express x16 (x8-wired) Gen 2 slot and one full-height and half-length PCI Express x16 (x8-

wired) Gen 2 slot with a maximum power usage of 75 watts for each slot. It integrates PCI Express card

support capability into the BladeCenter architecture. Up to four expansion blades can be attached to an

HS23. Each expansion blade occupies a bay in the BladeCenter chassis.

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 (BladeCenter E, H or HT), 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 (BladeCenter H

or HT). With BladeCenter S, both GbE ports are routed to the chassis I/O bay 1, and both 10 GbE ports are

routed to the chassis I/O bay 2 using the 10Gb LOM Interposer Card (if installed).

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.

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.
