The Square Kilometre Array (SKA) is an ambitious project to build the world's largest radio observatory: a low frequency (50 { 350 MHz) array in Western Australia, and a mid-frequency (0.35 { 15 GHz) array in South Africa. The SKA's Global Headquarters will be at the Jodrell Bank Observatory in the UK. Once in steady-state operations, the SKA will have one of the largest data rates of any research infrastructure in the world. One key challenge for SKA is to manage its digital data they are passed from receptors in the field, through several stages of processing before being delivered. In addition, a global network of SKA Regional Centres (SRCs) is planned, where advanced data products will be generated and processed for analysis, collaboration, publication and preservation. This paper will describe the operational concept for the SKA and the challenges faced by its distributed operational model. The paper provides an update on the current work leading to the development of a collaborative network of SRCs around the world.
