Software defined storage (SDS) is a key component of the IT transformation process. Acording to this definition, a network-shared NFS server would not be a distributed filesystem, whereas Lustre, Gluster, Ceph, PVFS2 (aka Orange), and Fraunhofer are distributed filesystems, altho they differ considerably on implementation details. Collectively it’s clear that we’ve all had it with the cost of storage, particularly the cost to maintain and operate storage systems. com 4 REFERENCE ARCHITECTURE Red Hat Gluster Storage on Supermicro servers powered ntel eon processors RED HAT GLUSTER STORAGE Red Hat Gluster Storage is a software-defined, open source solution that is designed to meet Glusterfs vs. Indeed, homogeneously scaling out the storage nodes and network infrastructure can result in both capacity and throughput capabilities that are directly proportional. ji@gmail.
