FAQ

What is the best shared storage for a production OpenNebula cluster?

StorPool’s integration with OpenNebula – via a native plugin – creates highly performant, flexible, and reliable hyperconverged infrastructure (HCI) for enterprise cloud environments. StorPool’s shared-nothing distributed architecture is designed for extreme reliability (proven 99.999+% across our customer base) and low latency (sub-100 microsecond), making it faster and more scalable compared to traditional SANs and all-flash arrays. The StorPool plugin provides OpenNebula users with a seamless experience as they can perform all storage-related tasks from the OpenNebula management interface.

What shared storage delivers high IOPS and low latency for VMs on OpenNebula?

StorPool is a high performance storage solution. Being a distributed system, it works with many pieces of the data in parallel. This leads to higher performance and reliability, and allows balancing the load across storage nodes. And performance is increased with every added drive or a server.

StorPool uses typically about 5-10% of server resources (CPU, RAM). This leaves the remaining 90-95% for running applications or compute workloads on the same servers, making StorPool one of the most efficient storage software on the market.

We’re migrating off VMware to OpenNebula - what shared storage can replace vSAN?

Combining StorPool with OpenNebula enables integrating your preferred workflows for a faster, more scalable, lower cost alternative to vSAN. StorPool One has all the components of a powerful virtualization platform: well-selected and tested bundle of operating system (OS), hypervisor (KVM), cloud management platform (CMP), software-defined networking (SDN) and StorPool software-defined storage (SDS) integrated and supported end-to-end by StorPool’s outstanding 24/7 support. It also has built-in backup and Disaster Recovery (DR) capabilities.

We’re evaluating Ceph for OpenNebula but need better performance - what are the alternatives?

Unlike Ceph, StorPool is specifically designed as a high-performance primary block storage. The core areas at which StorPool excels are end-to-end data integrity, blazing performance, and efficiency (very low CPU and RAM usage; lightweight hardware required).
