Advanced features are what really add value to v. Sphere and help distinguish it from its competitors. The features covered in this chapter provide protection for virtual machines VMs running on ESX and ESXi hosts, as well as optimize resources and performance and simplify VM management. These features typically have many requirements, though, and they can be tricky to set up properly. So, make sure you understand how they work and how to configure them before using them. High Availability HAHA is one of ESXs best features and is a low cost alternative to traditional server clustering. HA does not provide 1. VMs, but rather provides higher availability by rapidly recovering VMs on failed hosts. The HA feature continuously monitors all ESX Server hosts in a cluster and detects failures, and will automatically restart VMs on other host servers in an ESX cluster in case of a host failure. How HA works. HA is based on a modified version of the EMCLegato Automated Availability Manager AAM 5. VMware bought to use with VMware VI3. HA works by taking a cluster of ESX and ESXi hosts and placing an agent on each host to maintain a heartbeat with the other hosts in the cluster loss of a heartbeat initiates a restart of all affected VMs on other hosts. Center Server does not provide a single point of failure for this feature, and the feature will continue to work even if the v. Center Server is unavailable. In fact, if the v. VMware HA and DRS are two critical vSphere features that will help solution providers monitor and manage VMs in their customers environment. Center Server goes down, HA clusters can still restart VMs on other hosts however, information regarding availability of extra resources will be based on the state of the cluster before the v. Center Server went down. HA monitors whether sufficient resources are available in the cluster at all times in order to be able to restart VMs on different physical host machines in the event of host failure. Safe restart of VMs is made possible by the locking technology in the ESX Server storage stack, which allows multiple ESX Servers to have access to the same VMs file simultaneously.

The job of the primary hosts is to replicate and maintain the state of the cluster and to initiate failover actions. If a primary host fails, a new primary is chosen at random from the secondary hosts. Any host that joins the cluster must communicate with an existing primary host to complete its configuration except when you are adding the first host to the cluster. At least one primary host must be functional for VMware HA to operate correctly. If all primary hosts are unavailable, no hosts can be successfully configured for VMware HA. HA uses a failure detection interval that is set by default to 1. HA settingdas. failuredetectiontime 1. Ecc 5.2 Cs 1.6 Zero more. A host failure is detected after the HA service on a host has stopped sending heartbeats to the other hosts in the cluster. A host stops sending heartbeats if it is isolated from the network, it crashes, or it is completely down due to a hardware failure. Once a failure is detected, other hosts in the cluster treat the host as failed, while the host declares itself as isolated from the network. By default, the isolated host leaves its VMs powered on, but the isolation response for each VM is configurable on a per VM basis. These VMs can then successfully fail over to other hosts in the cluster. HA also has a restart priority that can be set for each VM so that certain VMs are started before others. This priority can be set to either low, medium, or high, and also can be disabled so that VMs are not automatically restarted on other hosts. Heres what happens when a host failure occurs. Enter-license.jpg' alt='Vsphere 5 Serial Key' title='Vsphere 5 Serial Key' />One of the primary hosts is selected to coordinate the failover actions, and one of the remaining hosts with spare capacity becomes the failover target. VMs affected by the failure are sorted by priority, and are powered on until the failover target runs out of spare capacity, in which case another host with sufficient capacity is chosen for the remaining VMs. If the host selected as coordinator fails, another primary continues the effort. If one of the hosts that fails was a primary node, one of the remaining secondary nodes is promoted to being a primary. The HA feature was enhanced starting with ESX 3. Arrow Powershot Pro Staple Gun Manual. VM failure monitoring in case of operating system failures such as the Windows Blue Screen of Death BSOD. If an OS failure is detected due to loss of a heartbeat from VMware Tools, the VM will automatically be reset on the same host so that its OS is restarted. This new functionality allows HA to also monitor VMs via a heartbeat that is sent every second when using VMware Tools, and further enhances HAs ability to recover from failures in your environment. When this feature was first introduced, it was found that VMs that were functioning properly occasionally stopped sending heartbeats, which caused unnecessary VM resets. To avoid this scenario, the VM monitoring feature was enhanced to also check for network or disk IO activity on the VM. Once heartbeats from the VM have stopped, the IO stats for the VM are checked. If no activity has occurred in the preceding two minutes, the VM is restarted. You can change this interval using the HA advanced settingdas. Interval. VMware enhanced this feature even further in version 4. HA. With application monitoring, an applications heartbeat will also be monitored, and if it stops responding, the VM will be restarted. However, unlike VM monitoring, which relies on a heartbeat generated by VMware Tools, application monitoring requires that an application be specifically written to take advantage of this feature. To do this, VMware has provided an SDK that developers can use to modify their applications to take advantage of this feature. Configuring HAHA may seem like a simple feature, but its actually rather complex, as a lot is going on behind the scenes. This document tracks the release of vSphere Web Client workflow functionality not available in the vSphere Client at the release of VMware vSphere 6. Update 1. ESXi and vCenter Server 5. Documentation VMware vSphere ESXi and vCenter Server 5. Documentation vSphere Installation and Setup Updated Information. Whats in the Release Notes. The release notes cover the following topics Whats New Internationalization Compatibility Installation and Upgrades for This Release. You can set up the HA feature either during your initial cluster setup or afterward. To configure it, simply select the cluster on which you want to enable HA, right click on it, and edit the settings for it. Put a checkmark next to the Turn On VMware HA field on the Cluster Features page, and HA will be enabled for the cluster. You can optionally configure some additional settings to change the way HA functions. To access these settings, click on the VMware HA item in the Cluster Settings window. The Host Monitoring Status section is new to v. Sphere and is used to enable the exchange of heartbeats among hosts in the cluster. In VI3, hosts always exchanged heartbeats if HA was enabled, and if any network or host maintenance was being performed, HA could be triggered unnecessarily. The Enable Host Monitoring setting allows you to turn this on or off when needed. Flex. Pod Data Center with VMware v. Sphere 5. 1 Design Guide. Table Of Contents. About the Authors.
