Lesson 6 VSphere VM creation and management

Lesson 6 VSphere VMS Create and manage 1-term 1-1 virtual hard disks in three formats:

Thick Provisioning Delay 0: Simply say: Reserve 500GB space (the value you entered), do not erase the data held on the hard drive, zero on demand

Thick Provisioning Setting 0: Simply say: Reserve 500GB space (the value you enter) thin provisioning that erases the persisted data on the hard disk, resets the zeros at once, and performs better on the first write

Thin provisioning: Similar to dynamic hard disks

1-2 Virtual Disk operating mode:

Turning on standalone persistence mode means that the snapshot feature is turned off

The independent non-persistent mode is turned on, which means that the snapshot function is turned off and the opportunity is restored to its original state at each turn

1-3vmtools function

1. Optimized SCSI Driver

2. Enhanced video and mouse performance

3. Virtual Machine Heartbeat

4. Virtual machine quiescing for snapshots and backups

5. Enhanced memory management

Optimization Features:

2-clone VMS

Understood as full replication

In a domain environment, problems with the same SID occur, and the problem can be solved by using a template

3-VM templates

Clone to TEMPLATE:VM is also converted to a template at the same time

Convert to TEMPLATE:VM disappears, converted to template

Create a custom specification ---> This is called when a new virtual machine is deployed

4-OVF templates

The OVF template is a compact format for exchanging virtual devices between virtual platforms, whether VMware VSphere, Xen server, or Hyper-V

Another VM template is not easy to transfer in two vcenter, then you can use the OVF template

Memory snapshot-A snapshot of the VM used for power-on status and a certain amount of capacity (Recommended Groove selection)

Silent snapshot-it is to stop and take a snapshot while reading and writing. Use File server for consistency
