Software-Defined Storage Solutions

LINBIT SDS is a flexible storage solution for both cloud and on-premise computing environments. It includes LINSTOR, an open source configuration management system for storage on Linux systems. Some features of LINBIT SDS include snapshots, encryption, and caching.

Software-Defined Storage Solutions

LINBIT SDS delivers ultra-fast, resilient block storage for private cloud infrastructure. The SDS solution enables commodity hardware to create high performance storage clusters. Thus LINBIT’s custom open source software-defined storage solution is perfect for cloud environments because it ensures application availability as your storage scales. 

Software Components

LINSTOR - Controller, Satellite, and User Interface

The LINSTOR® system – one key software component of LINBIT SDS – enables replication between nodes in a cluster, providing resilient block storage devices to users and applications. It consists of multiple server and client components. 

  1. A LINSTOR controller manages the configuration of the LINSTOR cluster and all of its managed storage resources.
  2. The LINSTOR satellite component manages creation, modification and deletion of storage resources on each node that provides or uses storage resources managed by LINSTOR.
  3. All communication between LINSTOR components uses LINSTOR’s own network protocol, based on TCP/IP network connections.
  4. The storage system can be managed by directly using a GUI or a command line utility to interact with the active LINSTOR controller. Alternatively, users may integrate the LINSTOR system into the storage architecture of other software systems, such as Kubernetes.
  5. Seamless integration to various cloud environments with many additional software including Ha Controller, STORK, Kubectl Plugin, Operator

DRBD - The de facto standard Block Storage Replication tool

DRBD® – the other key software component of LINBIT SDS – is a distributed replicated storage system for the Linux platform.

It is implemented as a kernel driver, several userspace management applications, and some shell scripts. DRBD is traditionally used in high availability (HA) computer clusters, but it can also be used to create larger software defined storage pools with a focus on cloud integration.

Companies implement software-defined storage (SDS) in order to easily provision and manage data storage, independent of the underlying hardware  environment.

Since the software simply presents a block device, users do not need to use complex, shared file systems. Because we can use a single node with a filesystem on top of a block device, backing disk failure is transparent to the end user.

SW/HW Agnostic

All LINBIT solutions work with COTS – commodity off the shelf (hardware) – or with plain VMs on a public or private cloud. Thanks to the OS kernel-based data replication software LINBIT’s solutions do not require SANs, shared storage, special fencing devices, or any other type of special enterprise hardware. 

A cloud environment demands high-performance and low-latency . Leveraging LINBIT SDS software, you can build your cloud on common off-the-shelf hardware; whether those servers are spinning disk, all-flash, or hybrid. These setups can be hyperconverged or dedicated storage/compute servers. LINBIT’s robust open-source software-based platform enables the deployment of large server clusters configurable to your specific use-case, eg edge-computing.
