 NexentaStor - Open Software Defined Storage 

Nexenta can extend VMware to a fully software-defined hyper-converged solution, using NexentaStor virtual appliances to present physical storage with redundancy and ZFS data protection as a fully VMware compatible datastore. Two virtual appliances can be setup to provide high availability.

NexentaStor 5.0 Overview

NexentaStor is the industry’s leading software-defined storage (SDS) platform, delivering full-featured, enterprise-class unified block and file storage services. As of version 5, NexentaStor is used by thousands of customers in configurations ranging from tens of terabytes to multiple petabytes as a replacement for legacy storage area network (SAN) and network attached storage (NAS) hardware appliances.

Unlike hardware appliances from traditional storage vendors, NexentaStor is delivered as software that can either be deployed on bare metal industry-standard x86 servers connected to shared SAS storage enclosures and devices, or as a virtual machine on a wide variety of hypervisors on premise or in public clouds. NexentaStor 5 incorporates a state of the art management framework exposing an exhaustive set of developer friendly, self-documenting REST APIs that are the foundation for all user management interfaces (CLI and GUI) and ecosystem plugins. NexentaFusion ships with NexentaStor 5 and provides a single pane of glass management interface for multi-system deployments.

Being delivered as software only gives customers new levels of flexibility and performance, eliminates hardware lock-in, significantly reduces storage costs, and generally simplifies storage management and scaling.

Nexenta HA Dashboard

NexentaStor provides standard file (NFS and SMB) as well as block (FC and iSCSI) protocol services. The software is deployed as a full storage operating system on standard x86 bare metal servers, or in virtual machines in private or public cloud. NexentaStor can be run in single-node configurations on internal devices or in dual-node high-availability (HA) cluster configurations, with SAS-connected shared backend devices.

NexentaStor builds on the open source OpenZFS file system to deliver high-performance, enterprise-class data services that effectively compete and win against legacy storage appliance vendors:

This mature set of features has allowed Nexenta to successfully sell into a wide variety of market verticals and use cases, from high-performance low-latency all-flash arrays supporting virtual environments and business-critical applications, all the way to large-scale cost-optimized backup and
archive repositories.

NexentaStor Use Cases

The ability to select the right hardware configuration for the right workload gives customers maximum flexibility. Having the same software stack running on high-performance all-flash, balanced hybrid and cost- optimized backup and archive setups simplifies data movement across tiers and management of the full storage infrastructure.

NexentaStor Software Architecture

NexentaStor 5 builds on the open source OpenZFS file system for its core data services and complements it with high performance block and file services, high-availability clustering, kernel based multi-site replication and the Nexenta Management Framework (NMF). As shown in the figure below, NMF provides a tight cover on the underlying storage operating system and handles all provisioning and management operations. From a user perspective, NMF presents an exhaustive self-documenting REST API that provides a consistent foundation for the system’s Command Line Interface (CLI), the NexentaFusion graphical user interface and all supported ecosystem plugins.

NexentaStor High Level Architecture

nexentastor high level architectureNexentaStor 5 benefits from all the scalability, performance, and reliability improvements in the core platform that were implemented over the last few years in NexentaStor 4. NexentaStor 5 also incorporates a number of new and enhanced device drivers, adding support for 25Gb/s and 40 Gb/s Ethernet interfaces, as well as 32 Gb/s Fibre Channel HBAs.

The Nexenta Management Framework was first introduced with NexentaStor 5.0 and fully replaced the legacy Nexenta Management Server (NMS), Nexenta Management Console (NMC), and Nexenta Management View (NMV) that were part of NexentaStor 4.x and all previous releases.

By design, NMF is a high-performance, multi-threaded, fault-tolerant management plane that provides a streamlined and simplified storage-centric management experience. Building the NexentaStor CLI as well as all management products on top of the NMF REST API ensures that all operations and all statistics available through the CLI and GUI are supported via the REST API.

NexentaStor REST API Management Screen

The NexentaStor REST API is self-documenting and provides an interactive Swagger user interface for
developers and technology partners looking to build storage automation and orchestration.

Day to day management operations are accomplished using the NexentaFusion management server, freely available with any NexentaStor 5 license. NexentaFusion complements any NexentaStor 5 deployment and provides a single pane of glass Graphical User Interface for multiple NexentaStor appliances. NexentaFusion is available as a VMware OVA and as a Docker container for simple deployment on any Linux host, physical or virtual. It incorporates intuitive workflows for all provisioning
and fault management tasks and delivers advanced analytics dashboards for detailed monitoring and troubleshooting, storing up to two years of historical service data.

NexentaStor High Availability

NexentaStor high availability (HA) allows you to configure two NexentaStor nodes to provide redundant access to storage pools. Active-passive (two NexentaStor nodes, one pool) and active-active (two nodes, two pools or more) configurations are supported. If a node is unable to deliver storage services for some reason, the other node automatically takes over. Technically, a NexentaStor HA configuration consists of an HA cluster where one or more HA services are running:

  • An HA cluster is a pair of NexentaStor nodes that share access to backend storage devices, have
    network connectivity to each other, and on which the high availability feature is enabled.
  • An HA service specifies the Virtual IP (VIP) address(es) or Fibre Channel ports for the HA cluster,
    the storage pool(s) to be protected, and which of the nodes initially provides clients access to the

To facilitate HA configuration for file and iSCSI services, each node should have at least one static IP address assigned to it, and each VIP should have its own static IP address.

Example NexentaStor High Availability Configuration

nexentastor high availability configuration

In this example, Node-A and Node-B comprise an HA cluster. There are two storage pools, Pool-A and Pool-B, that consist of backend storage devices that are accessible to both nodes in the HA cluster. There are two HA services in this configuration: one that provides access to Pool-A using VIP-A and another that provides access to Pool-B using VIP-B. In this example, Node-A serves as the backup for Pool-B, and Node-B serves as the backup for Pool-A. Node-A and Node-B exchange status information using a number of different network and storage heartbeat mechanisms. If all of the heartbeat mechanisms are disrupted for a given length of time, then the main node is considered to have failed, and the backup node takes over. In this example, failure of Node-A would lead to Node-B taking over Pool-A and VIP-A, and failure of Node-B would lead to Node-A taking over Pool-B and VIP-B.
Once the failed node is restored, it can take back its storage pool. You can configure this to occur automatically when the node comes back online, or you can do this manually.
