A. B. C. D.A.
Before enabling deduplication and compression in a VMware environment, it is important to verify certain things to ensure that the process goes smoothly and does not cause any issues. These verifications include:
A. Adequate space is available: Enabling deduplication and compression will cause the data on the disks to be compressed, which means that more data can fit into the same amount of space. However, it is important to ensure that there is enough space available to accommodate the compressed data. Therefore, it is important to ensure that adequate space is available before enabling deduplication and compression.
B. Ensure disk groups are balanced: Disk groups in VMware are used to store virtual machine data. If the disk groups are not balanced, the deduplication and compression process may not work efficiently. Therefore, it is important to ensure that the disk groups are balanced before enabling deduplication and compression.
C. Autoclaim mode is enabled: Autoclaim mode is a feature in VMware that automatically assigns disks to disk groups. This feature should be enabled before enabling deduplication and compression to ensure that the correct disks are used for deduplication and compression.
D. All hosts are in maintenance mode: Enabling deduplication and compression can put additional strain on the hosts in the VMware environment. Therefore, it is recommended that all hosts be placed in maintenance mode before enabling deduplication and compression. This will ensure that the hosts are not overloaded during the process.
In conclusion, before enabling deduplication and compression in a VMware environment, it is important to verify that adequate space is available, disk groups are balanced, autoclaim mode is enabled, and all hosts are in maintenance mode. This will ensure that the process goes smoothly and does not cause any issues.
