Pilot version

The solution from Eltechs, called Eltechs ExaGear Server, used to be a part of ARM-as-a-Service platform (the service was available on www.armasaservice.com. It’s been recently stopped).

Basically, Eltechs ExaGear Server provides a fully transparent way of allowing users access to the low power benefits of ARM-based solutions while being able to provide customers with services that run on conventional Intel-based software. Moreover, Eltechs’ solution helps ISVs run their Intel-based programs on the Viridis without porting or modifying the initial software; avoiding any heavy investment in ARM-based hardware and decreasing time-to-market.

So how does this work? Take a look at the video below to see the product in action:

Benchmark results

Eltechs ExaGear Server targets datacenters and cloud providers and enables them to further decrease TCO by running Intel software on power-efficient ARM-based servers. It is reliable, easy-to-use and fast.

But how fast is it? In order to find it out, we have performed a series of tests. The tests take a look at the overhead introduced running x86 applications through our translator technology and take a close look at the performance implications for CPU intensive workloads, IO, and network intensives workloads.

Benchmark Description

For this benchmarking exercise, Eltechs ExaGear on Boston’s ARM-based Viridis servers, we have used GeoBenchmark freely available on http://geocomputing.narod.ru/benchmark.html. This benchmark evaluates a systems capability to perform data processing and provides a good benchmark to stress both CPU in IO system capability. The benchmark was built for the ARM architecture and Intel 32-bit. Results of ARM-based (or native) tests were compared against Intel 32-bit tests started under Eltechs ExaGear Server.

For both sets of tests same Boston Viridis server was used.

Input and Output

These tests simulate processing modules with heavy disk input & output. During those tests, Eltechs ExaGear Server demonstrated exceptional performance of more than 90% out of the native in average.

Multi-CPU

These tests are designed to estimate pure SMP performance and performance of SMP computers on the “memory access sensitive” algorithms. They show how good applications scale in multiprocessor and multithreaded environment.

Results clearly show that Eltechs ExaGear server is super scalable and does not impact parallelism of multi-threaded applications.

Conclusion

Eltechs ExaGear Server demonstrated excellent performance, in particular under heavy IO tests with nearly zero impact on performance while running Intel applications on ARM-based servers. This proves Exagear to be an excellent choice for running storage applications, disk and networking intensive tasks in translation mode on ARM servers today.

CPU intensive performance was around 50%. In future Eltechs expected to go as high as 80% out of the native performance in average.

Scalability tests clearly showed that Eltechs ExaGear Server is highly scalable. It does not affect parallelism of applications and can be transparently used for respective software.

Taking into consideration the ease of use, transparency for end users, and the immediate results – the Eltechs Exagear Server provides a real solution for the problem of migrating old legacy applications to ARM in the datacentre.
