How much storage does VMware use?
For Installation — 80MB (Linux) or 150MB (Windows) free disk space required for basic installation.
How do I monitor a VMware Datastore?
Click the name of your VMware ESX/ESXi monitor to open it in a new dashboard. In the monitor’s dashboard, click on the hamburger icon near the name of the monitor, and click Edit. In the add monitor form that opens up, enable monitoring Datastores by selecting Yes under Discover and auto-add resources.
How does VMware manage storage?
vSphere Virtual Volumes—manages storage objects packaged into virtual storage arrays. This makes the virtual machine a unit of storage management, comprising one or more virtual disks, which appear to storage hardware as a regular disk drive.
What is SAN storage in VMware?
A storage area network (SAN) is a dedicated, independent high-speed network that interconnects and delivers shared pools of storage devices to multiple servers. Each server can access shared storage as if it were a drive directly attached to the server.
What is VMware active memory?
Active memory is the amount of memory actively used by the virtual machine. This may differ from what the guest operating system reports because the guest operating system generally has a more accurate view of the memory actively used.
What is VMware Vmci?
The Virtual Machine Communication Interface (VMCI) is an infrastructure that provides fast and efficient communication between a virtual machine and the host operating system and between two or more virtual machines on the same host.
What should the CPU overcommitment be in VMware?
The CPU overcommitment parameter is the ratio of the number of virtual processors assigned to VMs to the number of physical CPU cores on the host. If the value is 3:1 – there should be no reason to worry. If the value is 5:1, VM performance degrades.
What can I do to improve the performance of my VM?
VMware Tools is a set of drivers and utilities used to improve VM performance and user experience. Graphics performance is increased after installing VMware Tools. The mouse is synchronized and works without lags. With VMware Tools, you can use a VM in the full-screen mode with higher performance.
What happens if you leave too much memory in a VM?
If you provide a big amount of memory for a VM and don’t leave enough memory for the host OS, then the host OS uses a swap file. This leads to the degradation of OS and application performance. Moreover, VM performance degrades as well in this case. Don’t assign too much memory to a VM, and, at the same time, leave some for the host.
How does a snapshot affect the performance of a VM?
Virtual disk snapshots reduce virtual disk performance. Each snapshot produces an additional delta VMDK file of a virtual disk. The copy-on-write mechanism is used. Each delta VMDK contains data differences (change log) compared to a parent VMDK file, and a VM reads all this data when interacting with a VM disk.
