Ceph is very reliable for Block and Object Storage
The ETERNUS CD10000 is desigend and quality assured for the usage as a hyper-scale storage system - it is not a generic IT platform. This is why Fujitsu is intentionally restrictive in allowing to run applications on a ETERNUS CD10000. The underlying operating system is of no significance as the system is sold as a storage appliance. Traditional RAID Storage Systems have also specialised operating systems.
Nobody would want to compromise the service level of a storage system by adding additional workloads at random. The fact that software-defined storage platforms run on x86 servers may create a temptation to mix storage and business application workloads on one platform but it is strongly recommended not to do so. Fujitsu is also aware that the file cababilities of Ceph are still limited. Therfore the system is realesed for block and object store in it's first relase. File will be suppoerted at a later point in time.
This is a big advantage of a packacked solution as only functions are released which enterprise users can rely on.
