Nop. Most internal data is spread between Ceph and home-made distributed storage system named EOS (https://indico.cern.ch/event/138478/contributions/149912/attachments/116849/165874/EOS-ALICE.pdf https://indico.cern.ch/event/138478/contributions/149912/att...) running over commodity hardware. The only commerical-backed storage system is the long term storage tape system. Still it has an home-made overlay API over it to interface with the rest of the systems.
