VSky A-Series
Scale-Out Storage Solutions

Powerful scale-out storage solution for enterprises and data centers

VSky A-Series are scale-out storage solutions that allow businesses to scale, access and archive at petabyte volumes, making them ideal for backup/archiving, media editing, video surveillance, virtual environments, content delivery and more.

Seamless scaling

The explosion of data has created massive challenges for IT professionals, who must now think on a petabyte scale. Unfortunately, many traditional storage systems are not able to efficiently and cost effectively store that much data. VSky A-Series overcomes these challenges, allowing customers to scale to petabyte volumes - with no downtime, a single flat name space and no capacity planning needed.

All-in-one storage solutions

Unlike competing solutions lacking multi-protocol access, VSky A-Series provides a single infrastructure with scale-out capability for object, file, and block level storage. As an all-in-one storage solution, VSky A-Series solved the complicated issue of managing different storage systems, delivering data protection and NAS, iSCSI and Object functions, via a single management interface.

Integrated solutions

The VSky A-Series are integrated solutions, which include both the software and hardware provided by Promise. This eliminates installation and support issues that arise when integrating software-defined storage and commodity hardware from different vendors.

VDI/Server virtualization

VSky's high performance iSCSI interface allows businesses to create an individual distributed storage pool that can be used dynamically in many different applications.
