ActiveStor 20 (now ActiveStor
Classic) was announced in August 2016 with increased capacity, using larger and faster disks. In November 2017, Panasas released the ActiveStor Director 100 and the ActiveStor Hybrid 100 (now ActiveStor Prime), which disaggregated the Director Blade, the controller node

In August 2020, Panasas announced a new version of PanFS that features
Dynamic Data Acceleration technology, which automatically tunes storage for small files and mixed workloads. While other storage systems assign data to media "tiers" based on how recently files were accessed, Dynamic Data

ActiveStor Ultra (introduced in
November 2018) is the newest generation of the Panasas ActiveStor storage system and features a re-engineered, portable file system that delivers performance and reliability on suitably qualified, industry standard storage hardware platforms.

The ActiveStor product line is a parallel file system appliance that integrates hybrid storage hardware (hard drives and solid state drives), the PanFS parallel file system, its proprietary DirectFlow data access protocol, and the industry standard NFS and CIFS network
155:. Panasas received seed funding from Mohr Davidow Ventures (MDV) and others. The first Panasas products were shipped in 2004, the same year that Victor M. Perez became CEO. Faye Pairman became CEO in 2011. Tom Shea, formerly Panasas COO, was appointed as CEO in 2020.

DirectFlow is a parallel data access protocol designed by
Panasas for ActiveStor. DirectFlow avoids protocol I/O bottlenecks by accessing Panasas storage directly and in parallel. DirectFlow was originally supported on
