In January, 2010, Panasas proposed an NFSv4.1 based on their Parallel NFS (pNFS) technology claiming to improve data-access parallelism [25] capability. The NFSv4.1 protocol defines a method of separating the filesystem meta-data from file data location; it goes beyond the simple name/data separation by striping the data amongst a set of data ...
Comparison [ edit ] Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
While WebNFS itself did not gain much traction, several important WebNFS features later became part of NFSv4, including use of port 2049, and the concept of a fixed "root filehandle" (which evolved from WebNFS public filehandles and allows exported filesystems to be accessed without needing the MOUNT protocol to learn their individual root handles first); both together allow NFSv4 to function ...
The benchmark employs 8 test procedures, with three executing standard floating point calculations, two with such as COS or EXP functions, one each for integer arithmetic, branching or memory assignments. Output from the original comprised parameters used for each test, numeric results produced and the overall KWIPS performance rating.
The latest versions of ONTAP 9 support NFSv2, NFSv3, NFSv4 (4.0 and 4.1) and pNFS. ... test and development purposes etc. ... ActiveIQ Unified Manager & Performance ...

Execute validated tests for analysis while monitoring the test and the test environment. Analyze Results, Tune, and Retest.
Such benchmarking studies are used to create yardstick comparisons, allowing outsiders to evaluate the performance of operators in an industry. Advanced statistical techniques, including stochastic frontier analysis , have been used to identify high and weak performers in industries, including applications to schools, hospitals, water utilities ...
