The site requirements for Oracle Exadata Database machine is actually the second chapter of the Exadata Database machine Owners guide. You can find this documentation on a storage cell in /opt/oracle/cell/doc.
Thanks Tycho for information,
Actually we are in process of implementing exadata machine, and before delivery we wants to arrange the site.
So can you please mention any note id for this.We can access above doc only after installation.
The doc you're going to want is the Exadata database machine owner's guide (E13874-29). And given it includes site requirement, it's a good idea to review prior to install! As part of your Exadata order, there will be a line item for installation services, and whoever is doing the installation services should supply you the doc.
thanks Marc for your help
