Hybrid Storage is Back, and TrueNAS WebShare Tech Deep(er) Dive | TrueNAS Tech Talk (T3) E048

Описание: With the AI-driven component price bubble in full swing, hybrid storage is making a comeback. Now if only there was a software-defined storage solution with a filesystem that handled hybrid SSD/HDD systems really well - anyone know one? Chris and Kris go through some of the existing and upcoming options to enhance your hybrid TrueNAS solution by combining SSD VDEVs with your HDDs. Later on, by viewer request, Kris digs deeper into the guts of WebShare - security design, back-end architecture, and the languages used. Plus, our first sponsor spot - it's us!
