zfs discuss - Mar 2010 - ZFS priorization for filesystems / zvols ?

Hello list, 

when consolidating storage services, it may be required to prioritize I/O. 

e.g. the important SAP database get all the I/O we can deliver and that it
needs. The test systems should use whats left.

While this is a difficult topic in disk based systems (even little I/o with long
head moves impacts I/O a lot) it seems to be solved on other systems (Netapp).

NetApp provides flexshare. Is there anything like this on ZFS or on the roadmap
(Mabe with a bug number) ?

Regards, 
Robert

Does Netapp solve it at the disk I/O or network?  It is easy to setup 
network QoS and prioritization in Solaris.
