The QXP-3X4PES PCIe card is designed to expand the capacity of a QuTS hero or QTS NAS by connecting to a QNAP TL PCIe interface JBOD. Multiple JBODs can be daisy-chained using high-speed cables to increase storage capacity to the petabyte level and manage the exponential data growth caused by archiving and backing up surveillance footage, RAW multimedia files, big data, and virtualization applications.
