> # FICON Tape Acceleration Configuration Guidelines

> FICON tape acceleration has the following configuration guidelines:

> - In addition to the normal FICON configuration, FICON tape acceleration must be enabled on both ends of the FCIP interface. If only one end has FICON tape acceleration enabled, acceleration does not occur.
> - FICON tape acceleration is enabled on a per VSAN basis.
> - FICON tape acceleration cannot function if multiple ISLs are present in the same VSAN (PortChannels or FSPF load balanced).
> - You can enable both Fibre Channel write acceleration and FICON tape acceleration on the same FCIP interface.

> Enabling or disabling FICON tape acceleration disrupts traffic on the FCIP interface.
