When Capacity is Limited

We got confronted with old hardware and notably very slow storage. The job we had to do involved, unavoidably, a large amount of Writing and reading. We’ll present and discuss some of the measures we tried / failed / succeeded to survive until we got our new+shiny hardware…It was a bit like pointing firehoses at a sink, and then try not to let it overflow.The key to capacity-management, in this case, was to carefully monitor our system, and to push it to the limit, but NOT Beyond.
