Higher Capacities, Lower TCO & Improved QoS

Conquer massive data growth with Zoned Storage

Data volumes created by enterprises, machines, and consumer-generated content continue to drive demand for data center storage capacities at petabyte, exabyte and even zettabyte scale. Today, large scale data infrastructure already uses tens of thousands of SSDs and HDDs. Managing the extreme scale of data in a cost-effective manner is quickly becoming a requirement.

Zoned Storage is an open, standards-based initiative to enable data centers to scale efficiently for the zettabyte storage capacity era. There are two technologies behind Zoned Storage, Shingled Magnetic Recording (SMR) in HDDs and Zoned Namespaces (ZNS) in SSDs. With a unified software framework, data can be intelligently placed on both SMR HDDs and ZNS SSDs to increase storage capacity, lower TCO and improve QoS. With Zoned Storage, data center and cloud providers can more cost effectively scale storage for the zettabyte age.

Intro to Zoned Storage

Benefits of Zoned Storage for the Datacenter

Zoned storage devices, such as ZNS SSDs are divided into zones, significantly simplifying the drive architecture and minimizing the need for complex data management. With a unified software stack, the host is able to intelligently place data in different zones which enables these key benefits:

increased-capacities
Increased Capacities

Higher density and scale as virtually no over-provisioning is required

improved-qos
Improved Qos

With minimal garbage collection required, the device controller can respond quicker

reduced-cost
Reduced Cost

Significantly reduced DRAM requirements and fewer support logic functions are required

increased-endurance
Increased Endurance

Because the data is not constantly re-written, the endurance is improved
