Introduction

Server-Side Cache

Modern-day applications are designed to handle large amounts of data processing causing them to generate larger I/O numbers. This results in VMs requiring more speed from the storage subsystem to handle all the I/O requests. Although the NVMe technology has already stepped into the storage market, it still lacks proper mechanisms to deliver all of its capabilities, especially as a shared storage and requires significant expenses. This creates a need for a system that can combine fast NVMe storage and already common SSDs into a single and cost-effective storage pool.

Problem

Problems of All-Flash & All-Flash-Backed IT Environments

All-SSD storage can satisfy most of the workload types but this depends on the NAND type you choose. Popular nowadays MLC and QLC flash may become not the best fit for the environments with a lot of daily rewrites due to their limited erase cycles.

While all-NVMe storage can potentially be a solution even for the applications with the highest I/O requirements, in daily usage, its potential is mostly left unutilized. As a result, you get the highest-performing system that remains idle most of the time.

Finally, implementing all-NVMe or expensive SLC SSDs requires significant costs which simply might not be an option for most companies.

Server-Side Cache Solution

By combining redundant NVMe drives such as Intel® Optane and inexpensive MLC and QLC flash StarWind brings a cache server software solution that is as reliable as all-NVMe and SLC solutions at a reasonable cost. Thanks to StarWind NVMe caching software handling all the writes, MLC and QLC get back in the game since they waste less erase cycles and can be effectively used as the main storage capacity.

StarWind provides you with the NVMe performance for the most I/O demanding applications without having to purchase costly all-NVMe storage. This allows for smart utilization of your storage system, where its performance potential is never wasted but is always enough for the workloads.

Moreover, for the cases where there is no possibility to add NVMe as a caching layer, StarWind can effectively make use of the RAM caching as L1 cache to still provide faster writes for the applications. Reliability is kept at maximum – StarWind basically mirrors data in cache between multiple nodes, creating distributed cache. This way, even when the power goes out, all data is safe, because redundant replicas are stored on all nodes.

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.
