Product information

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.
PetaSAN is designed to provide users with highly available iSCSI in a Ceph cluster without requiring Ceph prior knowledge.
MultiPath iSCSI volumes, each identified by a virtual IP address, provide fast I/O and path redundancy. PetaSAN distributes Ceph's iSCSI drives to the individual physical drives in the cluster. In the event of a node failure, these virtual IPs can be dynamically and transparently moved from one node to another.
EUROstor develops tailor-made systems that are optimally adapted to this Open Source solution.
EUROstor offers customized systems, which are optimally adapted to this Open Source solution. Data (OSD), monitoring (MON) and iSCSI gateway functions can also be combined in the same node. For higher performance it is recommended to outsource the monitoring function to dedicated nodes, which EUROstor gladly offers as well.
