While this evolution brought obvious advantages, especially in terms of flexibility for the LHC experiment’s data management systems, it also raises the...

When investigating a problem, one typically needs to gather and correlate information from disparate sources: operating system, batch system, data transfer tools, and so on. We investigate the use of Control System Studio to gather information from multiple places. When the appropriate hooks are created, this should allow the end user to create ad-hoc ways to mix and match data without the...

The reliability of hard disk drives (HDD) has been quantified historically by a mean time to failure (MTTF), or an annualized failure rate (AFR), defined at a specified operating temperature, and an assumed functional duty cycle. We provide justification for replacing the ambiguous concept of duty cycle with the readily quantifiable “workload”, which is defined as the total amount of data...
