Traditional buffer caches, confined within a single machine’s expensive DRAM, encounter limitations in capacity and scalability, leading to performance bottlenecks as a result of costly disk fetches. Conversely, datacenters often face underutilization challenges. By circumventing traditional network protocol overheads, RDMA offers low-latency, high-throughput access to remote memory pools, thereby minimizing performance penalties. This study investigates the integration of RDMA (Remote Direct Memory Access) with buffer caches to overcome these challenges. RDMA enables memory disaggregation, allowing buffer cache capacities to extend beyond individual machine constraints by leveraging memory resources across multiple servers. This study assesses the efficacy of RDMA-enabled disaggregated buffer caches in enhancing application operations by expanding distributed capacity, leading to improved performance characterized by reduced latency for file accesses and enhanced throughput. This thesis serves as a preliminary study and demonstrates seamless integration with existing applications, eliminating the need for modifications to the application stack. Performance evaluation using various data-intensive POSIX application-level databases, such as LevelDB, SQLite, RocksDB, and WiredTiger, illustrates significant reductions in access latencies, enhancements in throughput, and improvements in cache hit rates.
