This is a Synology 2U rackmount storage system with 24 x 2.5-inch drive bays, powered by an AMD EPYC processor, shipping with 64GB of ECC memory and expandable up to roughly 1TB. Notably it supports installing a GPU card internally -- useful for hardware-accelerated video transcoding, AI/ML inference on stored data, or Synology's surveillance/deep-learning packages -- but the listing specifies it does NOT support external expansion units, so its 24 bays are the system's full, fixed storage capacity with no option to add further drive shelves later. Suited to mid-sized organisations needing a self-contained, GPU-capable storage platform without a long-term drive-expansion roadmap.
