4/19/2023 0 Comments Affinity group definitionTo fill this need, people at many companies have started affinity groups - groups united by a common interest or a common goal - to foster this kind of community. If you are part of a marginalized or differently-abled group, it can be helpful to find community with people like you at work. At Fairygodboss, our goal is to help connect women and nonbinary professionals connect with organizations that prioritize diversity and equity, as well as serve as a resource for organizations to improve their own DEI initiatives. Diverse workplaces are more likely to be inclusive, progressive and equitable - but they do not eliminate the experience of difference. Preferential rules can be violated to allow the proper functioning of DRS, vSphere HA, and vSphere DPM.Diversity in the workplace is often a point of positive discussion and for good reason. Ensure that the number of hosts in the cluster with which each virtual machine is affined is large enough that losing a host does not result in a lack of hosts on which the virtual machine can run. To avoid these situations, exercise caution when creating more than one required affinity rule or consider using VM-Host affinity rules that are preferential only (those where the virtual machine DRS group 'should run on' or 'should not run on' the host DRS group). vSphere DPM does not optimize power management by placing hosts into standby mode.DRS does not place virtual machines for power-on or load balance virtual machines. DRS does not evacuate virtual machines to place a host in maintenance mode.If improperly used, required VM-Host affinity rules can fragment the cluster and inhibit the proper functioning of DRS, vSphere HA, and vSphere DPM.Ī number of cluster functions are not performed if doing so would violate a required affinity rule. Accordingly, you should exercise caution when using this type of rule because of its potential to adversely affect the functioning of the cluster. DRS only tries to satisfy activated rules and deactivated rules are ignored.ĭRS, vSphere HA, and vSphere DPM never take any action that results in the violation of required affinity rules (those where the virtual machine DRS group 'must run on' or 'must not run on' the host DRS group). When two VM-Host affinity rules conflict, the older one takes precedence and the newer rule is deactivated. So it is possible for you to create a rule that conflicts with the other rules you are using. When you create a VM-Host affinity rule, its ability to function in relation to other rules is not checked. For example, a virtual machine that belongs to two DRS groups, each of which belongs to a different required rule, can run only on hosts that belong to both of the host DRS groups represented in the rules. Be aware that this has implications for how the rules interact. If you create more than one VM-Host affinity rule, the rules are not ranked, but are applied equally. When using VM-Host affinity rules, you should be aware of when they could be most useful, how conflicts between rules are resolved, and the importance of caution when setting required affinity rules. You use a VM-Host affinity rule to specify an affinity relationship between a group of virtual machines and a group of hosts.
