Resource pools are a very useful tool, they allow you to create pools of resources on a cluster using that cluster’s CPU and memory. Then you are able to create VMs on those resource pools and those resource pools will only provide the resources they are limited to to those VMs you can even put…

Yes you read that right, you can actually use shared storage in a vCenter without the use of a NAS or physical SAN all you need is VSAN, virtual storage area network, this is a software defined storage solution from VMware. How it works is when you setup vSAN all the drives in your host…

NFS, or network file system is another file system in vCenter. It is commonly used by NAS (Network attached storage). Similar to VMFS NAS supports file locking so that only one host can access a VMs files at a time, host 2 doesn’t need to access the files of a VM running on host 1….

Datastore cluster are very similar to host clusters, just for an example you have a vm on one host that host goes down that VM goes down. You have a VM on a cluster and one host goes down the VM can be moved with DRS or HA and everything is ok. With a datastore…

Learned a bit more about both VM override as well as vm-vm and vm-host affinity and anti-affinity. VM overrides are pretty simple with services such as HA and DRS enabled at the cluster level you can use VM overrides to change these setting on certain VMs say set DRS to manual or disable HA on…

So let me start this off with a scenario, all your VMs are down, but don’t worry you have HA setup and the VMs are starting back up on another host, however, your other VM running AD has started last so all of that time you spent waiting for it to come up your other…

So as stated in the title fault tolerance is very similar to HA. If a host goes down it ensures the VMs remain up, however how it does this is different. FT is enabled at a per-VM basis and in order for fault tolerance to even work you need to enable FT logging on at…

Just touched up on vSphere High Availability (HA). Not super complicated really HA allows for VMs to be restarted when a host goes down. You simply enable HA on the cluster and it monitors the hosts, how the cluster determines the node is down is by having the “primary host” monitor the entire cluster, vCenter…

Today I dove a little bit more into DRS, or Distributed Resource Scheduler. DRS is an incredibly useful functionality in vCenter, it allows VMs to be moved, or give suggestions on how they should be moved, based on resource utilization and when hosts are brought down for maintenance. There’s manual, partially automated, and automated DRS….

Content libraries in vCenter are actually pretty interesting and not a very discussed topic. So when you need multiple hosts or VMs to be able to access resources between each other in the same vCenter you can set up shared storage, typically vSAN. Now what do you do if you need to share files between…
