Permabit has a new version of its Albireo technology with a clustered “GX” version, which allows a grid of up to 16 processors to act as a single real-time de-duplication system. In the benchmarks they ran using hardware SHA-256 hashing de-duplication, they achieved a throughput increase of 13 times from 16 nodes in the grid compared with a single node, as shown in Table 1.
The maximum throughput for a single de-duplication system with 16 nodes using 64KB blocks is a very impressive 77 GB/sec. The single system means that de-duplication indexing is shared across the 16 nodes and is therefore much more efficient than 16 separate systems.
Permabit makes its technology available for hardware and software storage OEMs, including BlueArc (for NAS) and Xiotech (for block). This allows the OEMS to offer real-time de-duplication of all data types, compared with the current restriction to backup and archiving of de-duplication solutions from companies such as EMC’s Data Domain.
Wikibon has developed a CORE methodology (Capacity Optimization Ratio Effectiveness), which is described in detail in the link. Wikibon has used that methodology to compare the Permabit solution with the A-SIS real-time de-duplication system and compression system announced by NetApp, which was the first of its kind. It also compares with IBM's Real-time Compression which is a high-performance compression data reduction solution. The assumptions used in the comparison are given in Table 2.
The results of the comparison between the ASIS and Albireo approaches are given in Table 3.
A CORE score of 1 means that the benefits of de-duplication equal the costs. The Permabit solution for de-duplication and the IBM Real-time Compression have a far higher CORE scores and a much better return on investment that the A-SIS and NetApp compression systems for the workload and cost assumptions made in the comparison.
- The workload analyzed is IO-intensive which favors high performance low latency solutions.
- Certain compression solutions are explicitly not designed for real time operation and may deliver high value in different use cases.
Action Item: Permabit has shown that Real-time de-duplication technology has the performance and throughput to be used for almost any application environment. It is compatible with and additive to compression technologies. Storage executives should be planning to introduce such technologies as a default “business-as-usual” in 2011, and expect to make a real impact on storage budgets.
