25.10.2

Simplyblock is happy to release the general availability release of Simplyblock 25.10.2.

New Features

  • Control Plane: The control plane can alternatively deploy into existing kubernetes clusters and co-locate on workers with storage nodes.
  • Kubernetes Support Matrix: Added OpenShift starting from version 4.20.0
  • OpenStack driver: OpenStack driver is now available. It has support for most optional features and is tested from OpenStack 25.1 (Epoxy). On request, older versions of OS may be supported.
  • The required memory footprint on storage nodes has been reduced from 0.2% of storage capacity to 0.05% of storage capacity.
  • Qos: Pool-level QoS feature has been added.
  • QoS Service Classes: A new feature to assign a service class to a volume. Service classes provide full performance isolation within the cluster.
  • Support for flexible erasure coding schemas within a cluster.
  • Support for RDMA fabric and mixed fabrics (RDMA, TCP)
  • Some write performance improvements during first write to volume and node outage
  • Support for namespace volumes. A single NVMe subsystem can expose up to 32 namespace volumes now

Fixes

  • Control Plane: Fixed a problem, which could lead to stuck deletes.

Upgrade Considerations

It is possible to upgrade from 25.7.6 and 25.7.7. It is possible to add rdma support for the fabric during online upgrade.

Known Issues

Use of different erasure coding schemas per cluster is available, but can cause io interrupt issues in some tests. This feature is experimental and not GA.
