CSG: Biggest Storage Challenge
• “Bootstrapping a funding plan for central storage services where growth is explosive.”Data growth
• “As Central IT, our biggest challenge is fighting the misconception that storage is ‘cheap.’”
Perception of cost
• “Well by volume it is research data storage and particularly data generated by instruments like telescopes and sequencers.”
