FlexSDS to be a scale-out software defined storage, that supports three topology modes:
- Single node scale up SDS, this mode supports only in node data redundancy
- Dual-nodes HA SDS, this mode is the minimum requires to support HA service, that provides notonly in-node data redundancy, but also cross-node data redundancy.
- Tree (+) nodes scale-out clustered SDS, this mode is true scale-out/scale-up clustered storage, that supports all types of data redundancy.
Install and deploy FlexSDS software defined storage is very easy, please follow the below steps to install and deploy single node, two nodes HA or 3 (+) nodes clustered SDS.
