Status: Legacy / discontinued

An enterprise 3U "double server" from 2019 that combines an app server and a storage server in one box, with dual Xeon E5 v4 chips and up to 1 TB of RAM. You choose between QNAP's ZFS-based QES or the app-heavy QTS system. This is data-center gear, not something for a small office.
