DDN has been involved with Lustre almost since the start. Over these 15 years, DDN has come a long way from supplying storage hardware components to Lustre users, to providing a full range of Lustre-related solutions. LUG is a technical conference and marketing presentations from sponsors are always boring, so rather than telling you how great the DDN Lustre offering is, I will use this time to review our experiences growing-up with Lustre and what we learned along the way. I will also discuss whether we should measure the age of Lustre in kangaroo, whale, elephant, human, or tortoise years, which is an important consideration for our future engagement with the Lustre file system. I will conclude with the observations that building, deploying, and supporting globally-consistent-open-source-distributed-file-systems is hard, and while we are doing whatever we can to make it easier, this is unlikely to change fundamentally in the near future.
