If the core of the solution is unchanged - the system kernel still relies on Illumos, a fork of OpenSolaris and storage on OpenZFS , the open-source fork of ZFS technology created by Sun Microsystems and now controlled by Oracle - NexentaStor 5.0 brings important interface and integration improvements with VMware vSphere.

In addition to a modernized graphical interface, the storage solution now has a Rest API to automate its main functions. This Rest API can be driven by Nexenta Fusion, a centralized console that allows you to drive from a single screen of multiple NexentaStor appliances and also provides analytics to optimize storage management on a large scale.
