Upgrade of Hera dCache to 1.8

• Problem with PnfsManager V3. NFS clients stucks after a while.
• Question on how to handle the namespace
• We will start with ILC and chimera.
• Which database for the new Chimear instance / postgres , (oracle)
• Orcale licence ordered
• We will very likely start with postgres and after the local oracle group commits to supporting dCache we will possibly move to oracle.
• Plan for DECEMBER : ILC, chimera, postgres, URI for tape backend.
• Old hera experiments will be converted later (some years)
• Goal is to get rid of srm-dcache.
• Zeus needs the upgrade pretty fast due to the required usage of vector read.
• srm-dcache will be merged with hera dcache but when ?????
• hardware is going to be ordered now
• more storage (10 thumpers)
• ILC extraction first , hera follows.
• ILC in November15 ( ILC absprechen, hard ware need to be available)
• Hera in December plus srm-dcache into hera-dcache.
