8.2.10 Create ODX Buffer Volume

This function creates a dedicated volume for the ODX function.

ODX is a function that offloads the load on data copying and migration to the storage system. ODX copies data

at the time when a copy request is received. If a Write command is issued for the copy source data, this

function backs up the previous data in the area that is to be overwritten. An ODX Buffer volume is used to

store the backup data at this time.

The ODX function is supported by "Windows Server 2012".

• To stop using the ODX function, the server must recognize that ODX is disabled in the ETERNUS DX Disk

storage system. After disabling ODX with this function, reboot the server.

• The ODX function cannot be disabled when ODX Buffer volumes exist in the ETERNUS DX Disk storage

system.

Delete the ODX Buffer volume before disabling the ODX function. Refer to "5.2.2 Delete Volume" (page 112)

for details.
