HCI-Flex Solves Many Common IT Problems

The HCI-Flex appliance brings together two best-of-breed entities, a highly reliable server foundation and the DataCore software-defined storage expertise to create a flexible HCI appliance that can be used to solve many of the most troublesome business and technology problems.


limited resources

For organizations with limited budget, storage management expertise, and space, the HCI-Flex appliance provides a cost-effective solution with an intuitive storage management console that makes it easy to implement, deploy, operate and maintain. The DataCore HCI-Flex appliance can be deployed in less than an hour into new or existing environments thus accelerating time to value so IT can focus resources on more business-critical projects.

Application Performance & Availability

performance and availability

For organizations trying to manage increasing expectations that technology becomes a center for business growth and profit, the HCI-Flex appliance empowers IT with data analytics and insights, significantly reduces downtime and dramatically increases application performance. DataCore Software-Defined Storage, the foundation of the HCI-Flex appliance, has been shown to increase application performance by up to 3X while decreasing storage related downtime by as much as 50%.


change management

For organizations seeking to reduce their dependency on multiple disaggregate management systems as well as complicated routes to maintenance and support, the DataCore HCI-Flex appliance provides proactive insights and trend data so capacity planning and remediation are simplified. The end result is a significant reduction in latency and downtime due to complications associated with change management, data migration and accidental misconfiguration.

HCI-Flex Appliance is a Great Choice For Many Use Cases

Remote Office/Branch Office

The HCI-Flex appliance is an ideal choice for remote locations and branch offices. Simple, intuitive deployment enables fast and easy setup in locations with limited or no dedicated IT resources. Once installed, the hyperconverged appliance can connect to a datacenter-based DataCore installation providing common data services and management across locations. This consistency of services streamlines and simplifies critical infrastructure management functions such as performance optimization, replication, failover and recovery.

Edge Computing

The volume and velocity of data is increasing at an overwhelming rate. Many businesses are adopting edge computing as a way to provide faster access to latency-sensitive applications and optimize network bandwidth. When deployed as an edge computing platform the HCI-Flex appliance can increase the speed of applications by up to 3X while preventing storage-related downtime. When connected to a DataCore installation located in the datacenter, the same benefits of data service consistency discussed above apply to the edge computing scenario.

The Value of Flexibility

The DataCore HCI-Flex appliance provides the ease of deployment, simplicity, and agility of hyperconvergence, along with a key differentiator: flexibility. With the HCI-Flex appliance you can efficiently manage internal storage while connecting to and utilizing external storage as well. This enables you to combine both internal and external capacity into a single pool and use auto-tiering across SSD, HDD and secondary storage to optimize performance while reducing overall costs. Scaling compute and storage independently eliminates potential overprovisioned compute and wasted capacity that result from limited, node-based growth. The HCI-Flex appliance can scale out up to 64 nodes giving you the freedom to allocate your storage to applications based on business needs.
