Virtual Storage Area Network Solutions
LINBIT VSAN is a turnkey SDS appliance that manages highly available NVMe-oF, iSCSI, and NFS data stores. It uses LINBIT software from LINBIT SDS and LINBIT HA to provide a unified storage cluster management experience with a simple GUI.
LINBIT® VSAN is a software-defined storage solution (SDS) that comes as an easy-to-deploy ISO image. You need to bring three machines (x86), of which at least two need to have built-in storage devices providing sufficient capacity for your HA data needs. It’s also possible to deploy LINBIT VSAN into virtual machines.
Our appliance has direct access to the local HDD, SSD, and NVMe drives. From these resources, a virtual data store can be created, which is then presented to a hypervisor or other workload via iSCSI, NVMe-oF, or NFS protocols. This virtual data store is highly available because the appliance always copies a replica of each block to a second virtual appliance. The number of replicas is customizable.
We deliver LINBIT VSAN as an ISO file. All configuration and administration tasks, including system upgrades, can be done via the graphical user interface — no LINUX skills required!
The solution needs at least three servers, but not all of them need to be full-blown virtualization servers. It is sufficient if two of them come with storage devices for the data store. All writes to the highly available data stores are mirrored between the first two servers. The third is needed to provide quorum in the system during the failure of one machine. You can equip either two or all three servers with CPU and memory suitable for running guest VMs.
A three-way redundancy configuration is the right choice for highly valuable data. Note that data stores of different redundancy levels may be arbitrarily combined in the same cluster. For example, you could equip server 1 with two NVMe drives, server 2 with two drives, and server 3 with just one drive. One of each server is designated for the 3-way redundant data store, the two remaining for a 2-way redundant data store.
The software is not limited to three-way redundancy – it is also possible to use four or more replicas. Here is a configuration with four nodes that exposes two two-way redundant data stores to the hypervisor software. All four nodes are utilized to execute VMs of the workload. The LINBIT VSAN appliance can scale up to 16 nodes in a single cluster.
Note that, for best results with the quorum algorithm, an odd number of nodes is optimal.
NOTE: There are many more configurations possible, get in touch with us to discuss the possibilities in the context of your requirements.
This solution contains a broad range of open source technologies: AlmaLinux, DRBD®, LINSTOR®, LINSTOR Gateway, and DRBD Reactor. Its focus is to make these complex technologies available to Linux and non-Linux users alike.
All of LINBIT’s components are packaged as RPM packages and integrated on top of AlmaLinux as it is best practice in the industry. The root account is available to the user. If an additional monitoring system should be installed, no problem. Open to any customization we at LINBIT did not envision beforehand.
