PetaSAN Overview

Scale-out Active/Active

PetaSAN is a scale-out active/active storage solution offering massive scalability and performance. PetaSAN uses modern cloud based technologies to provide the elasticity and agility to scale up the storage cluster simply by adding more nodes; this can be done at any time and in a truly non-disruptive manner.

Protocols

PetaSAN currently supports iSCSI, CIFS/SMB, NFS, S3 and native Ceph storage.

Easy to use

Although PetaSAN uses different underlying technologies that are inherently complex, it provides an integrated end to end solution that is very easy to install and operate. PetaSAN can be operated by non-Linux admins through its easy to use graphical interfaces while still allowing Linux experts full control if they wish. PetaSAN brings proven technologies powering many of today’s largest clouds to the datacenter with point and click interfaces.

Components

At the storage level PetaSAN relies on the Ceph storage engine. Ceph is the leading edge open source SDS cloud storage solution powering many of today’s private clouds and public clouds. Ceph is a fault tolerant, self healing and self adapting system. At the service level PetaSAN uses Consul service mesh platform for cloud scale service management. Gateways for iSCSI are implemented using LIO, CIFS/SMB using Samba ,NFS using Ganesha and S3 object storage.

Use cases

PetaSAN is ideal for deployments requiring many i/o operations that need to be executed in parallel. Example cases of high i/o concurrency include:

VMware vSphere deployments
MS Hyper-V deployments
Setting up scale-out file systems: CIFS/SMB, NFS and MS Scale Out File Server (SOFS)
Big Data Analytics
Database Servers with many parallel transactions per second
Large capacity backups

PetaSAN is Open Source

PetaSAN is licensed under the AGPL 3. PetaSAN current version uses a kernel up streamed from SUSE Linux Enterprise 15 with a few patches, Ceph Octopus and Ubuntu 18.04 LTS for its root file system. PetaSAN is in active development, we welcome any community involvement, feedback and suggestions for new features through our forum.
