Unlimited Scalability

The most scalable & flexible file systems. The ZFS file system does offer unlimited volume size and unlimited storage capacity expansion.

ZFS Scalability

While data security and integrity is paramount, a file system must provide scalability without gotcha upgrade costs. ZFS designers either removed or greatly increased the typical limits imposed by legacy file systems by using a 128-bit architecture, and by making the metadata dynamic. The power of NexentaStor is built upon the industry proven 128-bit ZFS file system that supports unlimited storage capacity with utilizing the “pay as you grow” philosophy.

OpenStorage architecture, such as the NexentaStor storage management software platform, makes it simple to reallocate storage capacity as demands change. A ZFS storage solution provides unlimited storage file size capacity, vastly increased performance, unified management of disparate storage media, achieve unlimited storage scalability, and meet the specialized requirements of cloud, big data, and virtualized storage.

The ZFS 128-bit addressing scheme and can store 256 quadrillion zettabytes, which translates into a scalable file system that exceeds 1000s of PB (petabytes) of storage capacity, while allowing to be managed in single or multiple ZFS’s Z-RAID arrays. 

Unlimited Storage Pools

Unlike a traditional legacy file systems that either resides on a single device or uses multiple devices and a volume manager, ZFS is implemented on top of virtual storage pools, labeled the zpools. While most legacy solutions limit the file sizes, there are no such limitations with ZFS storage solution.

A pool is constructed from virtual devices (vdevs), each of which is either a raw device, a mirror(RAID 1), or a RAID-Z group. The storage capacity of all the vdevs are available to all of the file systems in the zpool. To limit the amount of space a file system can occupy, a quota can be applied, and to guarantee that space will be available to a specific file system, a reservation can be set.
