Context Before
KV cache grows linearly with sequence length and multiplicatively with workload parallelism, quickly expanding beyond what any single tier of memory was designed to hold. GPU HBM, while unmatched in bandwidth and latency, is not enough on its own to store KV especially for longer sequence length queries that are becoming popular between turns or tool calls. Host DRAM extends capacity but remains node-bound and
Evidence
limited in aggregate footprint and ultimately has limited capacity.
Context After
Meanwhile, traditional shared storage—architected for durability rather than latency—has more access time and power overhead, making it unsuitable for participation in the decode loop.
