A 200 Meg file is likely to be completely cached in the ftp server's RAM 
- and the cheapest way to get performance is to be sure that happens.

It would probably be simpler to provide a separate interface or two for 
the ftp server <-> storage network than to go too crazy with 
multipathing.  And for an ftp server you shouldn't need a great deal 
more speed on the filesystem side than you have on client connection side.
