Introduction

Deduplication and Compression

The amount of data in virtualized datacenters keeps growing exponentially, making VM-centric storage solutions ever more expensive. This creates a challenge for vendors when it comes to developing storage that can sustain continuous data growth and maintain required levels of performance. With virtualization having to store roughly double the amount of data that it had to during the previous two years, the demand, popularity, and production of virtual server and desktop infrastructures are starting to explode. To deal with the expected data growth, businesses will need products capable of delivering exceptional levels of storage efficiency and unique capabilities at an optimal cost.

Problems of Compression and Deduplication in All-Flash Environments

Modern IT Specialists and System Administrators face a problem where vastly growing amounts of data require an increase of available capacity in their storage subsystem. Adding new storage arrays or scaling up existing ones is leading to increased power consumption and OpEx as well as CapEx.

With flash storage becoming industry standard for storage arrays, the increased amount of data written to modern SSDs causes premature flash wear-out, increasing the failure rate of the drive, which is critical for arrays with high $/IO and $/TB ratio.

The increasing amount of production data grows the size of backup infrastructure at an aggressive rate. More data business needs to store twice as much data must be stored on backup targets according to the 3-2-1 rule. Among other methods, organizations need to enable deduplication and compression.

Increasing the number of storage arrays results in unnecessary costs $$

Solution

StarWind VSAN Deduplication and Compression

StarWind Virtual SAN implements in-line deduplication using industry-standard 4 KB block for highest effectiveness and optimal deduplication ratio. Deduplication is then followed by optional compression of written data blocks. There is a specific set of benefits that is inherent to StarWind VSAN Deduplication and Compression.

  • More available storage on existing arrays eliminates the need to scale up or scale out, minimizing expenses
  • Less written data also means less erase and write cycles, resulting in much better flash storage utilization and flash cell lifespan.
  • StarWind VSAN combines deduplication and compression with high availability, providing reasonable performance and uptime numbers while enabling space reduction.

With VDI scenarios where the amount of overlapping data is close to 90%, StarWind's in-line deduplication makes it possible to elevate the performance further by implementing in-memory computing.

StarWind in-line deduplication writes physically less data to the array

Conclusion

Increase Storage Utilization Efficiency of Flash-based Storage with In-Line Deduplication

StarWind Virtual SAN dramatically increases the usable space available on the storage by means of deduplication and compression before data physically hits the storage array. This process increases storage utilization efficiency, thereby reducing the expenses needed to operate your storage infrastructure while increasing flash storage lifespan.

Success Stories

We were able to build 2-node storage clusters based on virtualization in 19 hypermarkets without any problems and with high cost-efficiency.

Vass Sandor, IT Infrastructure Leader

By being able to virtualize our environment with StarWind, we were able to retire some old hardware, get our services highly available, reduce power consumption and heat in our server closet.

David Gardner, Information Systems Manager

We are satisfied with StarWind. The support is really fantastic. Whenever any issue arises, the response is very prompt, and solution is immediate.

Srinivas Kouda, Company’s Representative

StarWind got us off the clustered environment, which was a big help. So, I could regain control of my storage and reclaim and redistribute the space we desperately needed.

Ryan Fulton, Company’s Representative

Price + Simplicity. StarWind VSAN offers great pricing and allows us to get work done without expensive custom hardware. It also makes getting back online quick and easy after an outage or hardware failure.

Aaron Hayes, IT Manager

We chose StarWind Mainly because of the cost compared to other vendors. Simplicity of setup was also a major factor and I like the fact that you don’t need a vendor certified engineer to perform the installation.

John Harris, Windows System Administrator,
Department of Physics, University of Oxford

Because of recommendations of older colleagues, with StarWind, we got a reliable storage with no additional hardware. There was a need to increase IT infrastructure performance and we saw StarWind as the most cost-effective solution.

Željko Medić, Director of IT Department

StarWind is the best storage product I have ever used! It satisfies and exceeds requirements.
