Network Storage

Links and Info

• EMC-IDC "Digital Universe" study 2012

  • Among the interesting facts in the report: The number of objects or files will grow faster than the overall volume of data over the next decade, growing 67 times compared to 44 for data, while storage capacity will grow only 30 times. And over that same time, the number of information professionals will only grow by a factor of 1.4, as demand will outstrip supply. That's good news for information professionals, if a challenge for CIOs, said Hollis.
  • The amount of data that needs to be protected will grow too, from 30 percent of all data to 50 percent by 2020, thanks to compliance and security demands.
  • Hollis also said he sees Ethernet as the storage networking technology of the future, noting that 40Gb networks can be had for $1,000 a port. "Every time, Ethernet wins," he said.

• Nunes @3Par sees less of a role for Fibre Channel drives in the future, as the combination of SSDs, SATA drives and automated tiering will meet the needs of the bulk of storage networking customers and save on storage costs over FC drives.
