What is the Permabit Storage Savings Estimator (SSE)?

The Permabit Storage Savings Estimator (SSE) is a tool designed to scan your data set and measure the savings you can expect when utilizing primary storage systems that offer Permabit’s industry leading data reduction with deduplication and compression.

Why has Permabit made the SSE available for download?

Permabit has made the SSE available to download so that Permabit and its partners can:

  1. Help customers determine the impact of data reduction in their storage  environment.
  2. Help customers determine where and when different types of data reduction  (data deduplication and/or compression) make the most sense.
  3. Compare the effectiveness of Permabit data reduction to other data reduction  solutions.

What is the benefit of using the Permabit SSE?

The Permabit SSE will help you to assess data reduction rates you should expect to see on specific volumes of data in your primary storage environment. This allows you to both better forecast your storage requirements going forward and to quantify the savings you will see when data reduction is enabled. Since results are reported separately for deduplication and compression, it’s a snap to determine whether a volume will benefit from deduplication, compression or both technologies combined.

How does the Permabit SSE work?

The Permabit SSE scans your filesystem using Permabit’s award-winning massively-scalable Albireo Deduplication Index to identify any previously seen 4K data blocks. HIOPS Compression algorithm is then applied only where needed to unique blocks. Estimated results of the combined deduplication and compression savings are then displayed in the SSE interface. (see figure 2)

How is the Permabit SSE deployed?

The Permabit SSE is delivered as a 64-bit Microsoft Windows application, installed via the standard Microsoft Software installation process. The easy-to-use Windows-based graphical user interface can be used to analyze file systems that are local or remote mounted.






Can I use the Permabit SSE to compare the effectiveness of data reduction products?

Yes, absolutely! We’ve made the Permabit SSE available as a free download so that Permabit customers and partners can compare the effectiveness of Permabit data reduction to that of other data reduction solutions.

Can I share my Permabit SSE results publicly?

When you accept the Permabit SSE software license, you acknowledge that all results are confidential between your organization and Permabit. Before you share your results publicly, or with a third party organization, you must obtain authorization from Permabit. You can request authorization by emailing us at info@permabit.com.

Do you have a similar tool I can run on Linux?

Yes. Permabit has a storage efficiency assessment tool (Albscan for Linux) that can be run directly from the 64 bit Linux command line. You may request a copy of Albscan for Linux by emailing us at info@permabit.com.
