Infortrend Deduplication in Action - Creating more NAS storage space (Page 4)

Intel NASPT

The Intel NAS Performance Toolkit (NASPT) is a file system exerciser and analysis tool designed to enable direct measurement of home network attached storage (NAS) performance. Designed to emulate the behavior of an actual application, NASPT uses a set of real-world workload traces gathered from typical digital home applications. Traces of high definition video playback and recording, office productivity applications, video rendering/content creation and more provide a broad range of different application behaviors.

Playing data back from the NAS doesn't show a large difference between our three tests.

On this chart we see a mix with both reading and writing data to the NAS and a 100% sequential data write test. The mixed mode test shows very little difference between neither of the enhancements activated and deduplication activated. The write test showed a significant drop in performance with dedupe enabled.

The combination with both dedupe and compression enabled slowed the EonNAS Pro 510 down the most as it should since more CPU resources are needed to compress the data.

Here we see the same downward decline in performance as we enable more compression technology, at least in the Office Productivity test.

The final set of tests shows performance all over the place and nothing like what we expected from the File Copy from NAS. The other tests on the chart show the same decline in performance.

CPU Utilization

The image above shows the CPU utilizations from no dedupe and no compression (top) and both dedupe and compression enabled (bottom).

With the data compression technology enabled, the CPU works harder than without when transferring the same data to the NAS.
