Virtual Machine Failure Monitoring

VMware® High Availability (VMware HA) monitors your virtual
infrastructure for ESX Server host failures and restarts virtual
machines that are interrupted by those failures on alternate hosts.
Starting with ESX Server 3.5, VMware HA can also detect and handle the
failures of individual virtual machines and respond appropriately based
on your specifications.
With this additional functionality, called Virtual Machine Failure
Monitoring, VMware HA deals with both host operating system and guest
operating system failures.

Firewall Configurations for Backup Clients on ESX Server 3

This document provides information about how to configure connections
between different backup software products and VMware® ESX Server 3
hosts. The document explains how to open predefined firewall ports for
supported backup products and how to open specific ports from a command
line. If the backup product you use requires additional configuration
changes to work with ESX Server 3, the document describes any specific
steps you need to perform.

Round-Robin Load Balancing

VMware® ESX Server 3.5 and ESX Server 3i version 3.5 enhance ESX Server
native multipathing by providing experimental support for round‐robin
load balancing. This technical note explains how round‐robin load
balancing works and how to set it.

Configuring and Troubleshooting N-Port ID Virtualization

N‐Port ID Virtualization (NPIV) is an ANSI T11 standard that describes
how a single Fibre Channel HBA port can register with the fabric using
several worldwide port names (WWPNs). This allows a fabric‐attached
N‐port to claim multiple fabric addresses. Each address appears as a
unique entity on the Fibre Channel fabric.
The primary source of information on configuring NPIV in a VMware
Infrastructure 3 environment is the Fibre Channel SAN Configuration
Guide, available on the VMware Web site.
This technical note provides additional details about certain specific
NPIV configurations and information on diagnostic techniques that may
be helpful as you configure NPIV. It also includes information to help
you understand error messages that may appear as you are working with
NPIV in a VMware Infrastructure environment.

Enabling NetFlow on Virtual Switches

NetFlow is a general networking tool with multiple uses, including
network monitoring and profiling, billing, intrusion detection and
prevention, networking forensics, and SOX compliance. NetFlow sends
aggregated networking flow data to a third‐party collector (an
appliance or server). The collector and analyzer report on various
information such as the current top flows consuming the most bandwidth
in a particular virtual switch, which IP addresses are behaving
irregularly, and the number of bytes a particular virtual machine has
sent and received in the past 24 hours.

VMware OVF Tool

The Open Virtual Machine Format (OVF) is a virtual machine distribution
format that supports sharing virtual machines between products and
organizations. The format facilitates the use of virtual appliances,
which are preconfigured virtual machines that package applications with
the operating system they require. Because OVF runs on multiple
platforms, a virtual appliance is ready to run without significant
additional configuration.
