many receive descriptors are used, the driver unnecessarily consumes memory resources. This property is only available through the HP Network Configuration Utility.

Multifunction Gigabit Server adapter properties

•SRB Timeout Delta. Increases or decreases the timeout value for I/O operations through the iSCSI HBA. Increasing this value may help prevent premature I/O timeouts if your network is highly congested and packets are being dropped frequently. The default setting is 15 seconds. This property only displays if iSCSI is enabled on the adapter. iSCSI capabilities are only available through HP Multifunction Gigabit Server Adapters and Multifunction Server Adapters for HP BladeSystem running Windows 2000, Windows Server 2003, and Windows Server 2003 x64.

•Receive-Side Scaling (RSS). Allows the network load from a network adapter to be balanced across multiple CPUs. (Microsoft Scalable Networking Pack (SNP) for Windows 2003 SP1 or later and Windows 2003 x64 SP1 or later)

•TCP Offload Engine (TOE). Offloads TCP connections to the Multifunction Server Adapter. (Microsoft Scalable Networking Pack (SNP) for Windows 2003 SP1 or later and Windows 2003 x64 SP1 or later environments only.) See the Microsoft (http://www.microsoft.com) website to download the latest version of the Microsoft Windows Server 2003 Scalable Networking Pack (SNP) and the required Microsoft hotfixes in article numbers 921136, 919948, and 923187 of the Microsoft Knowledge Base (KB).

Windows 2000 adapter properties

•802.1p QoS. The 802.1p QoS parameter is a standard that enables Quality of Service. This parameter is disabled by default. To change this parameter, select Enable or Disable.

•Checksum Offload. Normally the Checksum Offload function is computed by the protocol stack. By selecting one of the Checksum Offload parameters, the checksum can be computed by the Gigabit Ethernet Adapter.

To enable one of the Checksum Offload parameters, select the parameter. o None. Disables checksum offloading

o Rx TCP/IP Checksum. Enables receive TCP, IP, and UDP checksum offloading o Tx TCP/IP Checksum. Enables transmit TCP, IP, and UDP checksum offloading

o Tx/Rx TCP/IP Checksum. (Default) Enables transmit and receive TCP, IP, and UDP checksum offloading

•Ethernet@WireSpeed. The Ethernet@WireSpeed parameter enables a 1000Base-T Ethernet adapter

to establish a link at a lower speed when only two pairs of wires are available in the cable plant. By default, this parameter is enabled. To disable the Ethernet@WireSpeed parameter, select Disable from the Value list on the Advanced tab.

o Disable. Disables Ethernet@WireSpeed

o Enable. (Default) Enables Ethernet@WireSpeed

NOTE: This property is not supported by NC1020 and NC7761 adapters.

•Flow Control. The Flow Control property allows the user to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the transmit rate. The side that is receiving the PAUSE frame will momentarily stop transmitting. The
