PetaSAN is one of the best open source SAN storage software available in the Linux world. PetaSAN is an Open Source scale-out SAN solution that distributes data redundantly across many nodes. The system is highly scalable and offers exceptional data security thanks to the advanced Erasure-Coding technology provided by PetaSAN’s Ceph-based architecture. This makes it possible to add or remove storage nodes at any time and without interruption.
Features of PetaSAN:
- Scalability – state-of-the-art that flexibly expands storage capacity to meet actual demand
- Multiple nodes – delivers n-way active/active iSCSI that distributes individual disk LUNs across multiple nodes
- Network Protocol:
- transforms iSCSI service of the Linux kernel into a scale-out service layer running on the Ceph storage backend
- supports iSCSI Persistent Reservations and VAAI in Hyper-V and VMware virtualization environments
- System Integration – provides an integrated end-to-end solution
- Cloud Integration – access to proven cloud technology for the data center
- Storage Engine:
- self-adapting and self-healing system with high reliability
- Ceph Storage Engine ensures that data is stored in an open standard format – without proprietary vendor lock-in
- Resource Management:
- internally used: LIO (www.linux-iscsi.org) for its target iSCSI server
- internally used: Ceph (www.ceph.com) for its storage engine
- internally used: Consul (www.consul.io) for distributed resource management in the cloud
