TRIM support

Hi all,

Does ScaleIO 1.32 support TRIM for SSD?

Re: TRIM support

Hi,

ScaleiO offers "Trim" capability which enables the host to instruct ScaleiO to decommission  previously provisioned blocks in a volume that are no longer in use.  

This can be done for Blocks which are aligned to 1MB boundaries.

Hope this helps,

Kind regards,

Mark

Re: TRIM support

@msr, thank you! Is it documented anywhere? Does TRIM support work if ScaleIO is deployed into ESXi?

Re: TRIM support

Hello,

I do not believe TRIM support is documented at this time.

If the OS supports TRIM, SIO will support it.  However, I need to verify this as ESXi support for TRIM in itself seems to be in question.

Thank you,


Sean

Re: TRIM support

TRIM is a part of VAAI functionality in ESX, which is supposed by ScaleIO
