Most large businesses, universities, and government organizations are using expensive primary storage or archiving systems to store persistent or static data, when less costly and more environmentally friendly options are available, according to a survey of 250 IT professionals released this week by storage vendor Copan Systems Inc.
Those surveyed are managing and storing large amounts of data, with more than half handling more than 100 terabytes and nearly 20 percent overseeing systems with more than a petabyte of data. The survey indicates that 71 percent are storing persistent data on primary systems or a mix of primary and archiving systems, and that 20 percent didn't know how much persistent data sits on their systems.
Analysts estimate that persistent data makes up around 70 percent or more of all corporate data, but only 30 percent of those surveyed thought that their persistent data amounted to that high of a percentage.
"All organizations should constantly seek better understanding of all their data so that they can employ the most appropriate and cost effective solutions, and nowhere is this more important than with the vast amounts of persistent corporate data," said Mark Peters, an analyst at Enterprise Strategy Group, in a statement. ESG estimated that persistent data constituted around 60 percent or more of all data, and its growing fast. "Yet many data centers simply do not have the right architecture in place to address this. Persistent data needs a different storage approach from dynamic data, both in terms of device and process, if users want improved operational and economic efficiencies in their data centers," he said.
There is no question that the amount of data that storage managers have to handle is growing fast. Some 41 percent of survey respondents said their corporate data has grown between 25 percent and 50 percent in the past 12 months, while 13 percent said it has grown 50 percent to 99 percent. Around 10 percent reported growth of more than 100 percent.
