Help on Logical volume creation on MR408 controller (Unmap capability)

[dotmax]

Hi to all, i'm configuring my first gen11 with a MR408i-o controller.

When creating a new logical drive i have to select if enable or disable the unmap capability. (see attached photo)

I suppose that i must/should turn it on only on ssd volumes, But I'm looking for some reassurance.

Thank you

Hi,

UNMAP Capability Feature at page# 28.

The UNMAP feature allows an application or OS to tell the storage array that the disk blocks contain deleted data so the array can deallocate the blocks, reducing the amount of space allocated or in use on the array.

Thank You!
