Do you want to deploy HCI? How do you compare solutions?

hyper-converged_racks-1-1.jpgHyperconverged infrastructures (HCI) are one of the drivers of the current data center revolution—39% of organizations have already deployed their first HCI solution.

According to ESG research, 31% of organizations are deploying HCI solutions first and foremost to improve scalability. Twenty-two percent tell us that their biggest challenges and concerns are performance issues around data locality, and 19% tell us they’re concerned about the lack of flexibility when scaling.

What’s the best way to compare the plethora of HCI solutions?

ESG’s world-class technical validation process reveals each solution’s most compelling performance traits and pin point its economic value for you, the decision maker. How do we do it?

Old and Busted

ESG’s Validation Analysts apply their decades of experience validating performance and scalability to extracting meaningful data when validating the performance of HCI solutions. Our recent HCI validations of solutions such as Cisco Hyperflex, Cohesity, and Microsoft HCI used traditional methods that synthesized typical VM infrastructure, OLTP, email, web, backup/restore, and VDI workloads using industry-standard tools such as IOmeter, Diskspd, HammerDB, and SLOB.

The challenge with these types of workload generators is that they were primarily designed to benchmark the performance of the storage subsystem. We expend considerable effort to create scenarios that allow us to benchmark the entire HCI solution, and consider HCI-specific issues including noisy neighbors and the amount of CPU required to run the environment as workload increases.

New Hotness

The good news is that the Transaction Processing Performance Council (TPC) just released TPCx-HCI, their benchmarking tool for HCI solutions.

TPC designed this hot new benchmarking tool to simultaneously stress the critical components of HCI, providing a much-needed faithful rendition of real-world HCI workloads. TPCx-HCI varies load on each individual server while maintaining a constant load across the entire cluster, mimicking real-world unbalanced scenarios. The benchmark also validates resiliency in the face of failure, testing data accessibility when a node is powered down ungracefully.

The Bigger Truth

ESG’s Validation Analysts are experimenting with TPCx-HCI right now. We believe this benchmark will enable us to validate and compare scaling, noisy neighbor, HCI O/S overhead, and other HCI-specific performance concerns. Follow us to see how the latest HCI solutions fare in this hot new take on measuring performance in real-world environments. And if you’re a vendor, contact me to ensure that your solution is among the first we validate.
