Hi all,
Does anybody have an insight to share on moving from traditional LUNs to pNFS and still being able to use ASM on a 12c environment? Any documentations on the benefits of moving away from LUNs to pNFS would be highly appreciated. I have done some research and it is clear that pNFS comes with enhanced security, enhanced efficiency, enhanced resource management and enhanced performance optimization per IBM. Application servers , or clients, can gain simultaneous access in parallel over multiple data<http://searchdatamanagement.techtarget.com/definition/data> paths to storage servers or nodes<http://searchnetworking.techtarget.com/definition/node>. Anybody using pNFS in their environment? Compared to LUN's, can we categorically say that pNFS has superior performance? Note below one of the selling points:
The pNFS architecture also eliminates many of the scalability<http://searchdatacenter.techtarget.com/definition/scalability> and performance<http://searchsoftwarequality.techtarget.com/definition/performance-testing> issues associated with NFS servers<http://whatis.techtarget.com/definition/server> because file<http://searchstorage.techtarget.com/definition/file-system> metadata<http://whatis.techtarget.com/definition/metadata> and protocol data are transmitted over the Internet Protocol (IP<http://searchunifiedcommunications.techtarget.com/definition/Internet-Protocol>) network<http://searchnetworking.techtarget.com/definition/network>, while file data travels over the storage architecture as files, blocks<http://searchsqlserver.techtarget.com/definition/block> or objects<http://searchsoa.techtarget.com/definition/object>.
How does the above statement compare with traditional LUNs?
Thanks and best regards,
Bill Ndolo
