A NAS with this chip runs models on its processor cores, so memory speed sets the pace: small models (about 1-4B) answer at a usable speed, bigger ones are slow. We plan around 54.4 GB for models, what is left after the NAS system and its storage services. Models run in a container (Docker) or the maker’s app store, and speeds assume the NAS isn’t busy with storage work.

More about this hardware

Maker	Intel
Type	NAS (network attached storage) processor
Share of memory for models	85% (what the NAS system and its storage services typically leave free at this size)
Chip	Intel Xeon Silver (4100 to 4300 series)
AI accelerator	None. Models run on the processor cores.
NAS models with this chip	QNAP TDS-h6889AXU-RP · QNAP TDS-h2489FU R2 · QNAP TDS-h2489FU · Synology FS6400 · Synology HD6500
Memory type	System RAM, shared with the NAS operating system and its storage services
Bandwidth figure	115.0 GB/s, estimated, see the note below
Note	One profile for every NAS built on this chip. Memory speed is an estimate from the chip’s supported memory in a typical NAS fitting; a unit with one memory module runs slower than one with two. Speed assumes the NAS is not busy with storage work.
