Subject client side I/O buffering

Hello,

I know that the client caches write requests before they send to a 
datanode and that the client uses read-ahead, but where exactly is this 
implemented, Hadoop or HDFS? Or better question, will write cache and 
read-ahead also available when Hadoop uses another filesysten than HDFS?

Thanks,
Lukas K.
