Implementation of IPv4 Reflection Scheme for Linux-Based Storage Systems
Linux program stack is very popular as a system platform in low range and middle range storage systems. On the one hand, it allows rely on powerful, well tested solution with full range of system services such as TCP/IP and Input/Output stack. Such solutions have good vertical and horizontal scalability. On the other hand, Linux is a general purpose system and requires extra efforts in and custom modification for Input-Output and Networking components in order to implement special use cases and reach maximum performance for data path. We discuss our implementation for IPv4 gateway holding mechanism (IP reflection) which allows IP storage system by fixing nearest gateway for each client bypassing regular routing scheme. Architecture and preliminary performance testing results are discussed.
