Pure-Play OpenStack vendor Mirantis revealed new benchmark results for running an OpenStack cloud at scale.

The company said the benchmark, developed to show how quickly and reliably OpenStack can respond to on-demand, real-world workload requirements for provisioning cloud resources, achieved a sustained rate of 9,000 new virtual servers per hour for over eight hours.

The test was initiated from cloud controllers at its San Jose-based data center.

Mirantis OpenStack was used to drive 250 parallel request streams for starting new virtual machines across a network to a complex of servers running in Houston, Texas, more than 1,800 miles away.

It used its Mirantis OpenStack 4.0(Havana) distribution running CentOS Ver 6.4 deployed in a high-availability configuration across distributed data centers for the test.

It used 350 physical servers on an IBM SoftLayer bare-metal, multi-datacenter cloud.

Mirantis OpenStack stood up 75,000 virtual servers, provisioned in parallel stream level ranging from 100 to 500 at a time.

The company said following results of the benchmark test enterprises wanting to run large-scale workloads can rely on OpenStack for a private cloud with up to 75,000 virtual servers.

Mirantis CEO Adrian Ionel said Mirantis OpenStack was built for scale and performance.

“This benchmark with IBM shows that OpenStack is maturing quickly as a robust private cloud alternative to any public cloud offering," Ionel said.

"We’re pushing OpenStack to its limits in harsh conditions that mimic real world production workloads and demanding customer use.”
