NCDE 7.86 Table 0-2 Teaming Driver Revision History Date Driver Version Overview of Changes March 5, 2008 9.20.0.0 Added support for the following: • Windows Server 2008 Removed support for the following: • HP NC31xx Fast Ethernet Adapters • HP ProLiant Essentials Intelligent Networking Pack (Advanced Features) • ProLiant Essentials Licensing support for the ProLiant Essentials Intelligent Networking Pack. • Windows NT and Windows 2000 August 16, 2005 8.10.0.0 Added support for the following: • NC320i, NC324i, NC325i and NC326i LOMs • Read-only web interface accessible through the System Management Homepage. • The ability to create a detailed log of your system configuration for submission to third-level technical support personnel. • Status of the active path and fast path states, along with member ID information and readability enhancements. • Dynamic dual-channel load balancing, so user intervention is minimal and the NIC grouping happens automatically. • User-specified preference order for transmit load balancing, so you can select which team member will be primary. April 29, 2005 8.0.0.0 Added support for the following: • NC370x NICs. • Detects IPMI enabled adapters and disables LSO to prevent members from not joining the team. March 25, 2005 7.86.0.0 Resolved the following issue: • Communication failures when upgrading or creating Switch-assisted Load Balancing with Fault Tolerance (SLB) team types. December 14, 2004 7.80.0.0 Added support for the following: • NIC Teaming Utilization Tab. This tab displays current and peak speed, throughput, and utilization information for the selected team and its members. • Ability to replicate network configuration settings from one ProLiant to a group of target ProLiant servers using the System Insight Manager (HPSIM) group configuration mechanism. Removed support for the following: • HP NC3121 Fast Ethernet Adapter Revision history 7 Table 0-2 Teaming Driver Revision History Date Driver Version Overview of Changes September 11, 2004 7.71.0.0 Added support for the following: • NC320T PCI Express Gigabit Server Adapter. Resolved the following issues: • Blue screen that resulted when the Dual Channel feature was enabled and each channel did not have at least one NIC with link during system initialization. • NCU no longer fails to create teams on a system that has never had this software installed before. August 18, 2004 7.70.0.0 Added support for the following: • large-send offload (LSO) and checksum offload advanced teaming features, which can reduce TCP/IP processing overhead. • NC 320T PCI Express Gigabit Server Adapter, NC 150T PCI 4-port Gigabit Combo Switch Adapter, NC 310F PCI-X Gigabit Server Adapter. • 802.3ad dynamic teaming which allows the user to create channels on the switch without configuring the switch. • ProLiant Essentials Licensing support for the ProLiant Essentials Intelligent Networking Pack. • Active Path Failover guarantees the team to use a port that has a path to a selected destination. • Fast Path Failover allows the team to use the most expedient route to a destination. • Dual channel teaming allows receive load balancing on a team connected to two switches. • Advanced teaming allows teams with dissimilar ports to use large- send offload and checksum offload advanced teaming features, which can reduce TCP/IP processing overhead. Introduction 8 1 Introduction 1-1 Abstract This whitepaper provides a high- and low-level discussion of the technology behind HP ProLiant Network Adapter Teaming for HP ProLiant servers running Microsoft Windows. HP ProLiant Network Adapter Teaming is software-based technology used by server administrators and network administrators to increase a server’s network availability and performance. HP ProLiant Network Adapter Teaming provides network adapter, network port, network cable, switch, and communication path fault recovery technology, in addition to, transmit and receive load balancing technology. 1-2 How to read this document This document is divided into three main sections. These sections have been designed to target three specific audiences: the executive, the first time user, and the advanced user. While a reader may skip to the section that is specific to their needs, HP recommends that any prior sections be read first because some information is not repeated in every section. 1-2-1 Section layout 1-2-1-1-1Section 2 : An executive overview of teaming Target audience: Executive The purpose of this section is to provide a high-level, executive overview and introduction to HP ProLiant Network Adapter Teaming. The main purpose of this section is to provide information for an executive seeking business justification to deploy HP ProLiant Network Adapter Teaming. 1-2-1-1-2Section 3 : Teaming fundamentals for the first-time user Target audience: Beginner to intermediate user In this section, an intermediate introduction to HP ProLiant Network Adapter Teaming is provided for the first time user or implementer. This section also can be used as a quick reference section for the occasional user. A general overview of the capabilities and options for HP ProLiant Network Adapter Teaming is provided. 1-2-1-1-3Section 4 : The mechanics of teaming for the advanced user Target audience: Intermediate to advanced user This section provides detailed information about the design, implementation, and configuration of HP ProLiant Network adapter teaming. The purpose of this section is to assist networking specialists, systems engineers, and IM professionals in the design and troubleshooting of environments incorporating this technology in HP ProLiant servers. Topics for this section include advanced technical discussions o
