Fast Cache on File Block luns

Question

HI all I want to hear you opinion on enabling on luns provisioned to the file part (File luns) I cannot se any recomendation on this in the latest Best Practices doc (docu42660) for VNX2 i can rember to have read i a earlier BP ore training doc, the its was not good to have Fast Cache on file luns, because of the striped way the datamover write to those luns (Vol's) So what can you guys recomend ?

There's not specific recommend to NOT use FAST Cache for FILE LUNs. Use of FAST Cache all depends on the type of IO you use.

See KB https://support.emc.com/kb/73184 for the best practices for FAST cache and KB https://support.emc.com/kb/15075 for examples of workloads that are not good for FADT cache.
