ESXi storage partitioning issue

[hkito]

Hi,

Since ESXi host server has 2 HDDs only and RAID 1 is applied. Thus only 1 partition (datastore) was created after installed ESXi.

• Is possible to create one more partition to separate OS (datastore for ESXi) and Data (datastore for VM) ? Is yes, how ?
• Otherwise, if only 1 datastore (storing ESXi OS and VM) existed. Will ESXi migration / update impact to VM ?

Thanks !!

The vmfs datastore created as part of the install is the partition you can use to keep VMs. If you dont have SAN.

the partitioning will cause no issues during migrations.

Below is an example of the partitions created on the local RAID when you install ESXi. The last one is the vmfs datastore.

Hi,

ESXi partitions is separated from the Datastore that you will create. So don't worry about that.

There is no big impact because all are in the same disks, but is local disks so dont expect to much performance(if need).

vMotion or live migrations are only possible between Storage Shared SAN. Not possible between local disks.

Hope this can help.
