RE: VMware ESXi 5 and LIO target: "WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hallo Nicholas,

it seems as if the following change on the ESXi side reverts back to pre-5.0 ESXi behaviour:


esxcli system settings advanced set --int-value 0 --option /DataMover/HardwareAcceleratedInit   (the setting gets active immediately, no reboot needed)


Unfortunately this is a global setting for the ESXi host, which disables the use of hardware-assisted disk I/O acceleration.
Therefore this setting might be a solution for home-brewed ESXi environments (like mine), but not for professional deployments.

Anyway I would like to follow-up this topic on the LIO target side.
Can you tell me about your thoughts/plans to get this topic resolved ?


Best regards
Sven
