QxStack Red Hat OpenStack


QxStack Red Hat OpenStack is a co-engineered OpenStack infrastructure which is based on the Red Hat OpenStack Platform. It is developed for cloud service providers and enterprises who are seeking robust, resilient, and highly available solutions in an OpenStack cloud environment.


Automation for Efficiency

In order to hasten the complicated OpenStack set-up process, QCT developed its own “QxStack Auto-Deployment Tool" by utilizing Ansible. By using Ansible Playbook, all prerequisites including networking, storage and some other custom settings for the overcloud deployment can be easily done to speed up the process of installation. This auto-deployment tool not only enhances agility but also minimizes the time to build a cloud.

Reliability of the Turnkey Cloud

QxStack Red Hat OpenStack features high availability (HA) on OpenStack platform. QCT also provides additional HA function on the network level. QxStack Red Hat OpenStack is a reliable solution proven to have high failure tolerance to reduce business downtime and data-loss risk, keeping OpenStack environments up and running with strong reliability.

Integration of Red Hat Ceph Storage

QxStack Red Hat OpenStack on QCT hardware, integrated with Red Hat Ceph storage; provides users with a highly versatile storage backend. Red Hat Ceph Storage is a distributed object storage with extraordinary reliability and scalability. We aim to provide an all-inclusive, highly integrated solution for lower CAPEX and OPEX.

Validation of the Optimized Solution

Working on a series of validation tests, including OpenStack Tempest for functionality and OpenStack Rally for load tests, QCT verified the operational status of OpenStack APIs.  QxStack Red Hat OpenStack discovered fundamental bugs between deployments and evaluated the performance and stability of a production environment under comprehensive stress tests.

State-of-the-Art Technology

Every OpenStack version is released around a 6-month cycle, which could cause inconveniences for administrators to manage their cloud. QxStack Red Hat OpenStack is aligned with Red Hat OpenStack release cycles, to enhance lifecycle management that eases the pressures that come with new software updates.
