Data acquisition system of experiment OKA dedicated to research of rare kaon decays on accelerator U-70 is described in the paper. MISS system with autonomous controllers to read out front-end electronics by sequential data read and buffer data for accelerator burst serves as the basis of a blocked DAQ. Data buffered in controller memory are transfered and processed at the end of accelerator burst. DATE package builds subevents from event fragments and events from subevents with event building network. Event building network with topology star is made with 1GbE interfaces and 24$\times$1GbE switch. Cluster file system GlusterFS is used to build a distributed storage system.
