We're currently running an Exchange 2003 Server on a Windows Server 2003 with all the mailboxes residing on Direct Attached SCSI. The Windows server is a physical machine - no need to virtualize yet....
Now, I'd like to use our brand new Open-E DSS box to put the MS Exchange mailboxes up there.
As far as I know I can chose between iSCSI and CIFS in order to access the networked volume from my Windows 2003 Server.
Is there any experience around, on how Exchange shows the best performance: iSCSI or CIFS??
(...Common knowledge would yell "iSCSI". But that was also te case two years ago, when, on my old company, we implemented a VMware host, accessing it's vmdk's on an open-e box: In the end we were more than happy that we ignored "common knowledge" and implemented it using NFS. :-))
The Open-E box as well as the Windows server are outfitted with dual port Ethernet cards, which will be configured as a bonded interface into the storage network, in order to give us more performance.
It would be nice if you could share your experiences (good ones as well as bad ones).
