Implementing Ultra Low Latency Data Center Services with Programmable Logic

Algo-Logic Systems just released a whitepaper on our Key Value Store at Hot Interconnects: "Implementing Ultra Low Latency Data Center Services with Programmable Logic."

Data centers require many low-level network services to implement high-level applications. Key-Value Store (KVS) is a critical service that associates values with keys and allows machines to share these associations over a network. Most existing KVS systems run in software and scale out by running parallel processes on multiple microprocessor cores to increase throughput.

In this paper, we take an alternate approach by implementing an ultra-low-latency KVS in Field Programmable Gate Array (FPGA) logic. As with a software-based KVS, lookup transactions are sent over Ethernet to the machine that stores the value associated with that key. We find that the implementation in logic, however, scales up to provide much higher search throughput with much lower latency and power consumption than other implementations in software.
