We have Esxi, Dell equallogic SAN array and windows OS.
I see the esxi says 7GB free space on that datastore.
Dell equalloigc says 100GB free space.
Here the desll array does not give correct info.
Does the Esxi give what the OS does, that is, disk space is being used by OS.

Is the datastore configured to take up the whole LUN you have configured on your Dell EQ array? Do you have thin provisioning configured anywhere (in vSphere or on your SAN)?

can you upload screenshots, the VMware Datastore, sometimes do not refresh automatically, and may take time to report correct usage.

100GB free on the Equallogic array yes, but Equallogic doesn't know what an ESX datastore is so it has no idea about what free space that has. Think of a 1TB hard disk with a 100GB partition on it with Windows on, the hard disk has 900GB free, but Windows only has 100GB less what's in use free.
