Since December 2006, I’ve been testing Oracle11g NAS capabilities with Oracle’s revolutionary Direct NFS feature. This is a fantastic feature. Let me explain. As I’ve laboriously pointed out in the Manly Man Series, NFS makes life much simpler in the commodity computing paradigm. Oracle11g takes the value proposition further with Direct NFS. I co-authored Oracle’s paper on the topic:
What Isn’t Clearly Spelled Out. Windows Too?
Windows has no NFS in spite of stuff like SFU and Hummingbird. That doesn’t stop Oracle. With Oracle11g, you can mount directories from the NAS device as CIFS shares and Oracle will access them with high availability and performance via Direct NFS. No, not CIFS, Direct NFS. The mounts only need to be visible as CIFS shares diring instance startup.
Anyone that likes simplicity and cost savings.

The Oracle11g Direct NFS feature is another classic example Oracle implementing features that offer choices in the Enterprise data center. Storage technologies, such as Tiered and Clustered storage (e.g., NetApp OnTAP GX, HP Clustered Gateway), give customers choices—yet Oracle is the only commercial database vendor that has done the heavy lifting to make their product work extremely well with NFS. With Direct NFS we get a single, unified connectivity model for both storage and networking and save the cost associated with Fibre Channel. With built-in multi-path I/O for both performance and availability, we have no worries about I/O bottlenecks. Moreover, Oracle Direct NFS supports running Oracle on Windows servers accessing databases stored in NAS devices—even though Windows has no native support for NFS! Finally, simple, inexpensive storage connectivity and provisioning for all platforms that matter in the Grid Computing era!
