#152 – Global File System Concepts

Chris EvansData Management, Guest Speakers, Software-Defined Storage

This week, Chris and Martin are joined by Douglas Fallstrom, SVP Product & Operations at Hammerspace, as the conversation on global file systems continues. Hammerspace has developed a global file system platform that caters for geographic data dispersion and sits above traditional storage.

In this podcast episode, Douglas explains some of the challenges of stretching data over distance – typically latency and getting effective throughput. When metadata and data are abstracted in a file system, these issues can be mitigated – global data sharing doesn’t imply a need for global locking. This separation of the control and data planes is probably the most important takeaway from this episode and one we’re likely to see replicated across the storage industry.

You can learn more about Hammerspace at https://hammerspace.com/ or follow them on Twitter at https://twitter.com/hammerspace_inc. Alternatively, wait a couple of weeks and we’ll have a more detailed interview with Douglas that digs into the product a bit more.

Oh and if you’re wondering about the name – here’s where it comes from – https://en.wikipedia.org/wiki/Hammerspace
