ActiveStor Ultra

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. 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 of Panasas storage system, from the storage nodes. In November 2018, Panasas introduced ActiveStor Ultra, which featured a completely re-engineered portable file system (PanFS® 8) running on industry standard hardware.


DirectFlow

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

PanFS

Panasas created the PanFS clustered file system as single pool of storage under a global filename space to support multiple applications and workflows in a single storage system. PanFS supports DirectFlow (pNFS), NFS and CIFS data access protocols simultaneously. PanFS 7.0 added a FreeBSD operating foundation and a GUI that supports asynchronous push notification of system changes without user interaction. 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 Acceleration assigns data based on file size to most efficiently use the underlying media. The "novel" method is designed to improve performance, eliminate manual tuning and control storage costs.
