Urvashi Karnani Gaur, D. D. Sonvane, Vaibhav Kumar, Rajesh Kalmady · 2020
SANMAN - Storage Area Network Management Software is an in-house developed Linux based software to manage, monitor and configure SAN based high capacity storage systems which are built over off the shelf commodity hardware. SANMAN is designed and developed using open source software components providing features of storage virtualization, volume management, access control and snapshot offered by all commercial proprietary SAN solutions. To ensure business continuity and disaster recovery in storage systems deployed on non-commercial hardware along with SANMAN, a remote replication module is developed and integrated with the software. SANMAN facilitates software defined orchestration and monitoring of storage resources. This paper discusses the implementation of remote replication module in detail which is developed using DRBD-9 (Distributed Replicated Block Device) software facilitating remote replication and automatic failover.
