[4] EMC Corporation bought ScaleIO in June 2013 for about $200 million, only about six months after the company emerged from stealth mode.

In June, 2020, VxFlex OS was rebranded to PowerFlex[6] and version 3.5 was released which included updates such as native asynchronous replication, HTML5 Web UI, secure snapshots and other core improvements.

In September 2023, PowerFlex 4.5 was released - new features include improvements in security and maintenance, management, file services scalability, Expanded CloudIQ Integration.

In May 2024, PowerFlex 4.6 was launched with Full Lifecycle Management for 16G Nodes, Software Defined Persistent Memory for compression on Fine Granularity Storage Pools, more Management & Orchestration Enhancements, Security Enhancements which includes Secure Component Validation (SCV)/TPM enablement on all PowerFlex nodes, SSO Integration with multiple Identity Providers and Protocols, more CloudIQ (now APEX AIOps Observability), On-Demand SDC Compilation and full VMware ESXi 8 management.

Other notable features include QoS, thin provisioning, in-line compression and HTML5 management (along with CLI and REST API's).

The PowerFlex core software can run on multiple hardware platforms, including on public cloud systems such as Amazon Web Services (AWS).

Lifecycle Management however is best on Dell PowerFlex nodes as the software can fully automate provisioning and patching up to the OS / hypervisor level.

The SDS component forms a highly parallelized pool of storage, with each media device (SSD/NVMe/etc) being used for reads and writes.

There is no caching layer in PowerFlex all-flash systems in order to take advantage of the direct I/O capabilities of the underlying media.

This performance is also greatly utilized to achieve PowerFlex's 6 nines of availability (99.9999%) by delivering extremely quick rebuilds if a device or node fails.

Storage and compute resources can be added to or removed from the PowerFlex cluster as needed, with no downtime and minimal impact to application performance.

The self-healing, auto-balancing capability of the PowerFlex cluster ensures that data is automatically rebuilt and rebalanced across resources when components are added, removed, or failed.
