In ZFS there are what are called “virtual storage spaces”, or also known as vdevs, which are basically the storage device, that is, the hard drives or SSDs for storage. The maximum storage capacity of a «pool» is 3 × 10 23 petabytes, so we will have more than enough space if we need it, in addition, we can have up to 2 64 disks in a zpool, and 2 64 zpools in a system. Other limits are 16 exabytes for the maximum size of a file system, and even 16 exabytes for the maximum size of a file. ZFS allows to create 2 48 snapshots natively, and also allows to create up to 2 48 number of files in the file system. ZFS has been designed in such a way that we never have limitations in real life. The manufacturer QNAP with its Linux-based QTS operating system, has been using EXT4 for many years, but has recently launched a new operating system called QuTS Hero that allows the ZFS file system to be used for mass storage, thanks to this decision, we will be able to We benefit from a large number of improvements in the integrity of files and their protection against possible writing errors.īefore we begin to explain the main features of ZFS, let’s talk about its “limits”. The ZFS file system is used natively on FreeBSD-based operating systems, such as the popular FreeNAS or XigmaNAS, two operating systems that are specifically geared for NAS servers. From this moment, we can find the ZFS file system in FreeBSD, NetBSD, Linux such as Debian or Ubuntu among others. In 2013 OpenZFS was launched under the Umbrella project umbrella, in such a way that ZFS could be used without problems in operating systems such as Linux and FreeBSD among others. At first there were problems with ZFS rights, so it was decided to make different “ports” to adapt it to different operating systems without having licensing problems.
ZFS is a file system that was originally developed by Sun Microsystems for its Solaris operating system, the source code was released in 2005 as part of the OpenSolaris operating system, but this made ZFS usable in other operating systems and environments.
