#75 – It’s ILM All Over Again with Chris Mellor

#75 – It's ILM All Over Again with Chris Mellor

Chris EvansData Management, Garbage Collection

Data volumes have always increased over time as we store more information with the hope that one day some of it will be useful.  Even 30 years ago on the mainframe, Information Lifecycle Management or ILM was a thing with tools like DFHSM used to move content around between disk and tape.  This week Martin, Chris Evans and Chris Mellor talk about the new range of data management or ILM products that are looking to resolve the current issues of data sprawl.

How do these products work?  It is all about data ingest, or just indexing?  What happens when data moves between platforms and how do files continue to be accessed?  Companies like Komprise claim to be able to move data without impacting the application or needing to use techniques like stubs.  Others like IBM Spectrum Discover, simply appear to do content indexing.  Ultimately, perhaps we need to move everything to object stores and dispense with file services altogether.  Can we ignore public cloud and can we get the S3 API moved to an open standard?  All questions the team attempt to answer on this week’s podcast.
