Journaling and I/O load

Hi there,

Thanks for you help in advance.

We are thinking turn on Archiving for Journaling, but I am a bit worried about the I/O load. Our current Netapp SAN is high on IOPS already, and I don't want stress it out and cause performance issues for other system.

So my question is how much more load it will put on the system if we turn on Archiving for Journaling?

We use EV 9.0.1 with Exchange 2003 on Windows 2008 server, Netapp version is 8. Assume we archive everything in Journaling mailbox.

cheers
