KV Cache Storage for AI
KV Cache Storage for AI: Capacity, Bandwidth and Architecture
For the overall planning boundary, make KV Cache Storage for AI a byte-and-bandwidth calculation. Derive KV bytes per token from the model's actual KV representation, scale it by concurrent context length, then calculate the reload rate required when reuse fails. The risk to surface is wrong KV size assumption.
Parameter count alone cannot describe KV cache because layer structure, head configuration, precision, context length, batching, and runtime implementation all matter. Use telemetry from the serving stack whenever possible. Validate the calculation with measured runtime KV allocation. Compare predicted and observed memory at several context lengths, then measure the network and storage traffic produced by a cache restore.
For LLM serving and AI platform engineers, the useful output is not only total TB; it is also the bandwidth needed to recover that state within an acceptable interval. That pair of numbers determines whether local GPU memory, host memory, CMX, or a broader storage tier is the correct place for the cache.

Use this as a screening calculation. It does not certify a design, guarantee benchmark performance, replace a provider quote, or override current OEM, software, network or facility documentation.
Before you buy
Four checks that keep planning estimates in context
Start with current documentation
Use the exact platform or OEM system guide as the source of truth for supported configurations and limits.
Keep assumptions visible
Every calculator input is an assumption until it is replaced by a measurement, vendor limit or facility design value.
Separate nameplate from application performance
Port speed, SSD peak rate, GPU memory and power ratings do not guarantee end-to-end workload results.
Escalate facility decisions
High-voltage distribution, rack electrical work, cooling design and liquid loops require qualified professionals and current codes.
