With enhancements across Ceph scale-out storage, enclosure support, security monitoring, and network storage services, QuantaStor v6.6.11 continues OSNexus' commitment to delivering highly scalable and operationally efficient software-defined storage infrastructure.

Optimized Ceph Scale-Out Performance for Large Object Environments

QuantaStor v6.6.11 introduces performance and scalability improvements designed for large-scale object storage deployments powered by Ceph.

Key enhancements include:

  • Optimized storage grid logic to better support clusters with hundreds of thousands of buckets
     

  • Improved pool configuration defaults for hybrid scale-out deployments
     

  • Performance optimized for Seagate CORVAULT & Exos X external storage backends

These improvements help organizations running large object storage environments achieve greater operational efficiency and reliability at scale.

Enhanced Seagate CORVAULT Monitoring and Stability

Integration with Seagate CORVAULT systems has been expanded to provide improved operational visibility and stability.

Updates include:

  • More proactive alerting for faster issue detection and remediation
     

  • Reduced polling overhead to improve system efficiency
     

  • Improved performance and operational simplicity when Seagate Exos X and CORVAULT storage systems are used in conjunction with QuantaStor scale-up & scale-out clusters.

These enhancements help ensure reliable operation in mission-critical storage environments.

Support for Western Digital Data24 Gen4 NVMe-oF JBOFs

QuantaStor v6.6.11 adds support for the newest generation of Western Digital Data24 NVMe-oF JBOFs, including:

  • Data24 41xx Series – Designed for scale-out deployments supporting a wide range of NVMe media, ideal for Ceph architectures
     

  • Data24 42xx Series – Built for dual-ported NVMe enabling high-availability architectures such as QuantaStor scale-up configurations using OpenZFS

Updated documentation and integration modules now allow administrators to view, monitor, and configure Data24 systems directly within QuantaStor via the platform's External Systems integration module.

QuantaStor v6.6.11 reinforces OSNexus' focus on delivering scalable, enterprise-grade storage infrastructure that combines open-source innovation with advanced management, automation, and integration capabilities.
