What kind of hardware are you running on your metadata array?

> During LAD’20 Andreas mentioned if I could share the Robinhood scan time for the 369millions files we have. So here it is. It took ~23 days for me to complete initial scan of all 369 million files, on a dedicated robinhood server that has 384GB RAM. I had it setup with all tweaks for database and client that was mentioned in Robinhood document. I only used 2 threads for this scan. Hope this reference helps.
