Local Organizer

StorPool is high-performance software-defined storage solution. It allows customers to build data storage out of standard servers (software-defined storage). It is intelligent software that enables public and private cloud builders to run storage and applications on the same standard x86 servers and delivers fast, scalable and cost-efficient block storage. StorPool has advanced fully-distributed architecture and is arguably the fastest and most efficient block-storage software for high performance computing, available on the market today.

15:30 – 16:00: Disaster Recovery solution with OpenNebula and StorPool

Boyan Krosnov,Chief of Product of StorPool
In this talk we’ll explore a DR solution based on OpenNebula, developed by StorPool and deployed at a financial services organization. This solution represents a break-through for OpenNebula and StorPool technologies in a very conservative sector.
The solution uses two OpenNebula orchestrators using the federated identities scheme and two StorPool storage systems connected to each other with an encrypted site-to-site link.
It highlights how easy it is to extend OpenNebula to perform additional functionality, even without modifying the upstream OpenNebula software. Disaster recovery solution with open nebula and storpool from OpenNebula Project
