Term
Describe the process to Mount an NFS Datastore
Definition
Go to the host's configuration tab and click 'Add storage'.
Select 'NFS' as the storage type.
Enter the NFS Server Name or IP, the mount point and a desired name for the datastore.
If the volume has been exported as read only, be sure to select Mount NFS Read only.
Term
Describe the process to unmount an NFS Datastore
Definition
Right click the datastore and select unmount!
Term
Explain why you may have multiple VMFS/NFS datastores because you have separate spindles
Definition
Having different spindles can help with performance. If multiple VMs, especially I/O intensive VMs are all sitting on the same datastore, there could be latency and performance issues.
Term
Explain why separate RAID groups may lead to multiple VMFS/NFS datastores
Definition
For certain applications, such as critical applications, you may require a different RAID configuration. E.g. you may use a different RAID configuration for the disks that logs sit on an a DB sits on for SQL server
Term
Explain why you might end up with multiple NFS/VMFS datastores for redundancy
Definition
If you are doing any sort of replication, you would want your replicated VMs to sit on different disks than your production VMs in the case of failure of production storage
Term
Explain why Tiered Storage may lead to multiple NFS/VMFS datastores
Definition
You may have a use case to have storage formatted in different arrays to service different tier applications.
