Nexenta by DDN, Inc., is a subsidiary of DataDirect Networks that markets computer software for data storage and backup, headquartered in San Jose, California. Nexenta develops the products NexentaStor, NexentaCloud, NexentaFusion, and NexentaEdge. [4] [5] It was founded as Nexenta Systems, Inc., in 2005.
In 2005, Nexenta was founded by Alex Aizman and Dmitry Yusupov, software developers and former executives at network vendor Silverback (later acquired by Brocade). [6] Aizman and Yusupov previously worked together as the authors of the open source iSCSI initiator software in the Linux kernel. [7]
The company was created to support the open source Nexenta OS project after Sun Microsystems released the bulk of its Solaris operating system under free software licenses as OpenSolaris. Nexenta OS was an operating system that integrated Sun's Solaris kernel and core technologies with applications from the popular Debian and Ubuntu operating systems. [8] [9]
Nexenta has been acquired by DataDirect Networks, it claims to aim for "a developer of high-performance storage for modern workloads including artificial intelligence and big data", [10] in May 2019. [11]
The company's entry into the data storage included use at Stanford University in 2012 and 2013. [12] [13] The field had been dominated by companies such as EMC Corporation, DataDirect Networks and NetApp, who sold hardware storage appliances.
Nexenta intended to compete by creating a storage system that did not require specialized hardware. [14] [15] Instead of producing hardware, the company would provide software to run on lower-costing commodity computing hardware, a model later marketed as software defined storage. [16]
Much of Nexenta's business comes from partners that provide hardware and services alongside Nexenta software. [1] [17] The company's software is pre-installed on storage systems from vendors including Supermicro, Cisco Systems and Dell.
Nexenta continued to contribute to free and open source software used in its products. When Oracle Corporation discontinued OpenSolaris in 2010, the company became a founding member of the illumos open source project that would replace it. [18]
Nexenta's product NexentaStor is software for network-attached storage (NAS) and storage area network (SAN) services. [1] NexentaStor was derived from the Nexenta OS based on the illumos operating system. [19] [20] The software runs on commodity hardware and creates storage virtualization pools consisting of multiple hard disk drives and solid-state drives. Data can be organized in a flexible number of filesystems and block storage, and files can be accessed over the Network File System (NFS) and CIFS protocols, while block storage uses iSCSI or Fibre Channel protocols. [21] NexentaStor allows online snapshots to be taken of data and replicated to other systems. For high availability Nexenta uses RSF-1 cluster to build a HA storage.
In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used.
Solaris is a proprietary Unix operating system originally developed by Sun Microsystems. After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris.
OpenSolaris is a discontinued open-source computer operating system based on Solaris and created by Sun Microsystems. It was also, perhaps confusingly, the name of a project initiated by Sun to build a developer and user community around the eponymous operating system software.
OS-level virtualization is an operating system (OS) paradigm in which the kernel allows the existence of multiple isolated user space instances, called containers, zones, virtual private servers (OpenVZ), partitions, virtual environments (VEs), virtual kernels, or jails. Such instances may look like real computers from the point of view of programs running in them. A computer program running on an ordinary operating system can see all resources of that computer. However, programs running inside of a container can only see the container's contents and devices assigned to the container.
Openfiler is an operating system that provides file-based network-attached storage and block-based storage area network. It was created by Xinit Systems, and is based on the CentOS Linux distribution. It is free software licensed under the GNU GPLv2
Nexenta OS, officially known as the Nexenta Core Platform, is a discontinued computer operating system based on OpenSolaris and Ubuntu that runs on IA-32- and x86-64-based systems. It emerged in fall 2005, after Sun Microsystems started the OpenSolaris project in June of that year. Nexenta Systems, Inc. initiated the project and sponsored its development. Nexenta OS version 1.0 was released in February 2008.
PulseAudio is a network-capable sound server program distributed via the freedesktop.org project. It runs mainly on Linux, various BSD distributions such as FreeBSD and OpenBSD, macOS, as well as Illumos distributions and the Solaris operating system. It serves as a middleware inbetween applications and hardware and handles raw PCM audio streams.
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules.
GNU variants are operating systems based upon the GNU operating system. According to the GNU project and others, these also include most operating systems using the Linux kernel and a few others using BSD-based kernels.
StorNext File System (SNFS), colloquially referred to as StorNext is a shared disk file system made by Quantum Corporation. StorNext enables multiple Windows, Linux and Apple workstations to access shared block storage over a Fibre Channel network. With the StorNext file system installed, these computers can read and write to the same storage volume at the same time enabling what is known as a "file-locking SAN." StorNext is used in environments where large files must be shared, and accessed simultaneously by users without network delays, or where a file must be available for access by multiple readers starting at different times. Common use cases include multiple video editor environments in feature film, television and general video post production.
In computing the SCSI RDMA Protocol (SRP) is a protocol that allows one computer to access SCSI devices attached to another computer via remote direct memory access (RDMA). The SRP protocol is also known as the SCSI Remote Protocol. The use of RDMA makes higher throughput and lower latency possible than what is generally available through e.g. the TCP/IP communication protocol.
Sun Open Storage was an open source computer data storage platform developed by Sun Microsystems. Sun Open Storage was advertised as avoiding vendor lock-in.
NexentaStor is an OpenSolaris or more recently Illumos distribution optimized for virtualization, storage area networks, network-attached storage, and iSCSI or Fibre Channel applications employing the ZFS file system.
Illumos is a partly free and open-source Unix operating system. It is based on OpenSolaris, which was based on System V Release 4 (SVR4) and the Berkeley Software Distribution (BSD). Illumos comprises a kernel, device drivers, system libraries, and utility software for system administration. This core is now the base for many different open-sourced illumos distributions, in a similar way in which the Linux kernel is used in different Linux distributions.
OpenIndiana is a free and open-source illumos distribution descended from UNIX System V Release 4 via the OpenSolaris operating system. Forked from OpenSolaris after OpenSolaris was discontinued by Oracle Corporation, OpenIndiana takes its name from Project Indiana, the internal codename for OpenSolaris at Sun Microsystems before Oracle’s acquisition of Sun in 2010.
In computing, Linux-IO (LIO) Target is an open-source implementation of the SCSI target that has become the standard one included in the Linux kernel. Internally, LIO does not initiate sessions, but instead provides one or more Logical Unit Numbers (LUNs), waits for SCSI commands from a SCSI initiator, and performs required input/output data transfers. LIO supports common storage fabrics, including FCoE, Fibre Channel, IEEE 1394, iSCSI, iSCSI Extensions for RDMA (iSER), SCSI RDMA Protocol (SRP) and USB. It is included in most Linux distributions; native support for LIO in QEMU/KVM, libvirt, and OpenStack makes LIO also a storage option for cloud deployments.
OpenZFS is an open-source file system and volume manager that provides advanced data management and protection features. It was initially developed by Sun Microsystems for the Solaris operating system and is now maintained by the OpenZFS community.
Proxmox Virtual Environment is a hyper-converged infrastructure open-source software. It is a hosted hypervisor that can run operating systems including Linux and Windows on x64 hardware. It is a Debian-based Linux distribution with a modified Ubuntu LTS kernel and allows deployment and management of virtual machines and containers. Proxmox VE includes a web console and command-line tools, and provides a REST API for third-party tools. Two types of virtualization are supported: container-based with LXC, and full virtualization with KVM. It includes a web-based management interface.
