I think iSCSI has the specific following advantage : as the lun on the Filer is saw like a local drive, the Oracle service can start to work with earlier in the boot process of the Windows machine Oracle doesn't have to wait for the network and mapped drive to be up to work with these data this way you can move more Oracle data on the Filer (except the registry entry, all Oracle files can be migrated there - binaries, conf, redo log, datafiles etc...). This way, the Desaster Recovery procedure becomes much simplier. I am not sure 100% so tell me if I am wrong.

Keep in mind the space limitations of LUN's. I am just reminding the list.
As performance goes, I would suggest getting a baseline on Cifs and see the difference on ISCSI. It can be drastic at the protocol, but the Filer needs to be ready for the performance internals. It can be a LOT of net traffic when you actually open up the GigE's for top performance.

We have a customer running 2 x 8.1.7 and 2 x 9.x oracle databases on a F820. In addition they are running 1 x informix, 1 x MSSQL2K and 1 x domino database on the same filer. No problem at all. Oracle supports UNC path for filenames, so you don't even have to map the drive. The customer has never complained about performance. If you don't like UNCpaths, you probable should consider iSCSI. You will get a drive that windows treats like a local drive and performance might be a bit higher.

Hi out there, has any one experiences with running oracle on a Windows Server on CIFS? You don't find many documents about it on the Netapps Site. All the whitepapers concerning Windows and Oracle are about SAN. What are the pros / cons and limitations of running Oracle on a CIFS Share? Thank You! Dirk
