Module cache_peer 

Structs

CacheServerParams

The peer’s half of the RW-blade handshake (KV overflow / SSM snapshots): its QP identity + the single RW MR.

RdmaConfig

RDMA rail selection for the blade. One (dev, gid_idx) per CX7 adapter; a client requests N rails and the peer registers its arena on each so the client can stripe traffic across both adapters (~1.75x aggregate on GB10).

Functions

serve

Serve a KV overflow blade on addr until interrupted. One thread per connection; each connection gets its own RW arena sized by the client.
