Today Red Hat Inc. announced the general availability of the latest version of its software-defined storage solution, Gluster 3.2. The 3.2 version comes with several new enhancements and features aimed at lower costs while improving small file performance and increasing data integrity. Gluster 3.2 will also have tighter integration with Red Hat OpenShift Container Platform.
As we previously said, Gluster built its business around GlusterFS, a distributed high-availability software-only file system that allows resources from various computing and storage devices to be pooled into a single, centrally-managed namespace. A Gluster storage pool presents itself to client as a standard POSIX device and supports NFS, CIFS, HTTP, FTP as well as the Gluster protocol. A unique feature of the software is that it doesn't require a metadata server to coordinate I/O. Rather, GlusterFS uses an elastic hash algorithm that allows any node in the pool to locate data anywhere in the cluster.
While Gluster has several benefits, the latest update addresses the issue that NAS storage has with scaling metadata intensive operations, particularly with small files (under a few megabytes). The biggest benefit of this would be for Red Hat OpenShift Container Platform registries’ storage. According to Red Hat, Container registries, the heart of any container platform, are critical to resident applications and need highly elastic, durable storage. In addition, faster metadata-intensive operations can improve day-to-day operations by as much as 8x, increasing the responsiveness of the storage system at scale and improving the overall end-user experience.
