| !!! warning "Hybrid model requirements" | ||
| Hybrid SSM/Mamba models require the hybrid memory allocator (HMA). `NixlConnector` and `MooncakeConnector` currently support HMA, while `LMCacheConnectorV1` and `MoRIIOConnector` do not advertise HMA support. If HMA is disabled or the selected connector does not support it, hybrid model startup will fail. For `NixlConnector`, set `VLLM_SSM_CONV_STATE_LAYOUT=DS` on every prefill and decode instance; see the [NixlConnector Compatibility Matrix](nixl_connector_compatibility.md#hybrid-ssmmamba-models). |
There was a problem hiding this comment.
Since #51052 this is no longer accurate. Hybrid Mamba/KDA state transfer was added
IMO this will go stale quickly. Better to describe the rule (connectors that implement SupportsHMA) and give examples, rather than an exhaustive list of who supports what
