München, Starnberg, 14. Juli 2015 – Erweiterungen und Verbesserungen in den Bereichen IOPS-Performance, Latenzzeiten, Datenschutz und Data Management…
Zum Hintergrund: Red Hat Ceph Storage und Red Hat Gluster Storage sind Open-Source-basierte Software-defined-Storage-Lösungen (SDS), die auf Standard-Hardware eingesetzt werden können. Die neuen Versionen Red Hat Ceph Storage v1.3 und Red Hat Gluster Storage v3.1, die laut Hersteller ab sofort verfügbar sind, enthalten Optimierungen und neue Funktionen in den zentralen Bereichen Datenschutz, Performance und Verwaltung. Red Hat Ceph Storage liefert dann eine verbesserte Leistung durch Optimierungen beim I/O und den Latenzen. Zu den erweiterten Sicherheitsfeatures von Red Hat Gluster Storage gehören hierzu die Unterstützung von SELinux im Enforcing-Mode und eine SSL-basierte Netzwerk-Verschlüsselung.
Nachfolgend für Interessierte weitere technische Details zu den Updates (aus Aktualitätsgründen in englischer Sprache):
Red Hat Ceph Storage 1.3 has a highly tunable, extensible and configurable architecture that offers interfaces for enterprise block and object storage and renders it well-suited for archival and rich media and cloud infrastructure workloads, such as OpenStack. Red Hat Ceph Storage 1.3 includes several new features and enhancements, such as:
- Robustness at scale, from improved rebalancing logic that prioritizes data integrity over other automatic functions, and a new rebalancing "pause" feature that reduces impact on performance during cluster changes. Red Hat Ceph Storage 1.3 also features time-scheduled scrubbing that prevents automatic administrative checks from occurring during peak hours and affecting performance, and sharding of S3 bucket metadata that enables bucket operation load balancing across a cluster.
- Enhanced performance, resulting from input/output operations per second (IOPS) and latency optimizations for Ceph running on flash storage devices, contributed by Intel and SanDisk; acceleration of virtual machine boot times using read ahead caching; and sustained block performance by limiting file system fragmentation.
- Operational efficiency improvements, including the lightweight, embedded Civetweb server to ease deployment of the Ceph Object Gateway, and faster execution of administrative actions on block devices, such as resizing, deleting or exporting, even with extremely large images. Red Hat Ceph Storage 1.3 also includes management support for multiple users and clusters via the Ceph UI and API, and API-based policy management that enables programmatic adjustment of failure domains and data placement.
Red Hat Gluster Storage 3.1 is a scale-out file store for public, private and hybrid cloud environments. Offering network file system (NFS), Server Message Block (SMB), and Hadoop Distributed File System (HDFS) file interfaces, Red Hat Gluster Storage is designed for enterprise virtualization, analytics, sync and share, and rich media workloads. Red Hat Gluster Storage 3.1 includes new features and enhancements, designed to increase performance and security at scale, such as:
- Support for erasure-coded dispersed storage volumes that reconstruct corrupted or lost data by using information about the data stored elsewhere in the system can reduce the need for RAID and replication and total cost of ownership by up to 75 percent.
- Tiering's automated movement of data between "hot" and "cold" tiers in a volume-based on-access frequency gives operators fine-grain control to deploy storage clusters that are both cost-effective and highly performant for a wide variety of workloads.
- Bit-rot detection scans data periodically to detect data corruption resulting from silent failures in underlying storage media, enhancing end-to-end data integrity.
- Enhanced security via support for SELinux in enforcing mode and SSL-based network encryption to increase security across the deployment; support for active NFSv4, based on the NFS-Ganesha project, to provide performant and secure data access through clustered NFSv4 endpoints
- SMB 3 capabilities, adding protocol negotiation, copy-data offload and in-flight data encryption to allow for efficient file transfer and secure access in Microsoft Windows environments.
