"WebMar 5, 2024 · The RDMA vs. RPC debate. A fundamental drawback of using RDMA to access remote data structures is that the client must use multiple network round trips if the server-side data structure uses pointer-based indirection. For example, the hash table in Pilaf has one level of indirection, and therefore requires two dependent RDMA reads per access. " - Otf rdma

Unfortunately, while using only programmable switches is feasible to support the mechanism, it may not be scalable as the available H/W resources (e.g., SRAM) comes at a pre-mium [15]. For example, given a multicast group of re-ceivers, RDMA header mapping rules have to be created.
