Overview

DRBD is a host-based software replication that has a fundamental limitation on replication I/O transfer performance. These limits are measured at up to 5-6G bps transmissions on TCP / IP-based 10Gbps networks. Therefore, in such environments, it is difficult to measure the underlying performance of DRX's buffering or compression. In order to measure the performance of any equipment or software, data must be input without limitation and the resulting output can be calculated. In this regard, drbdsim is a tool developed to solve performance measurement problems.
