PetaSAN是其中一個在Linux世界裡最佳的開源SAN儲存軟件。PetaSAN也是一個開源可擴充的SAN方案，散佈數據重覆於多個接點。 系統是具有高度的可擴展性及提供特別的資訊保安，需要感謝她們的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.
PetaSAN功能：
- 可擴展性 – state-of-the-art that flexibly expands storage capacity to meet actual demand
- 多個接點 – delivers n-way active/active iSCSI that distributes individual disk LUNs across multiple nodes
- 網絡通訊協定:
- 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
- 系統整合 – provides an integrated end-to-end solution
- 雲端整合 – access to proven cloud technology for the data center
- 儲存引擎:
- 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
- 資源管理:
- 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
