Ceph can provide block (mostly used for VMs), object and file targets, in that order of maturity.
Gluster is sort of a metafilesystem, aggregating some number of underlying filesystems - file being the operative word.
- rodgerd 8y agoI'm referring to the FS primitives. GPFS presents a POSIX FS, but it's primitive is blocks. Ceph is an object primitive (RADOS) and can present it a number of ways. And Gluster is based around files as primitives, which gives some interesting strengths and weaknesses.
