Top Ten IT Trends for 2013–Trends 3 and 4
by Hu Yoshida on Dec 13, 2012
Trend 3: Explosion of Data Replication
Today’s businesses require more and more copies of data for faster point-in-time recovery, business continuity, business analysis, data sharing, extract-translate-load, data mobility, and auxiliary batch processing. A recent study by IDC finds that “In many environments, creating and managing multiple copies has exceeded the cost of primary storage, driving many organizations to seek new ways to ensure data availability, recovery, and reuse.” IT must start to focus on reducing or eliminating redundant copies of data that do not change. One of the biggest creators of copies is backup along with all the snap shots, remote copies, and versioning that is associated with business continuity. The volume of replicated data will blast to new levels in 2013 unless IT focuses on the reduction of copies through tools like active archives.
Trend 4: The Emergence of Enterprise Flash Controllers
Currently solid state disks (SSDs) are built with low-cost, commodity controllers to manage the durability and performance of the flash media. These controllers have limited processing power, bandwidth and memory; therefore the durability, performance and capacity of flash SSDs is limited to approximately 400GB with a 5-year life, subject to a specified number of writes/formats. In 2013, we will see the introduction of flash controllers that are built specifically for use in enterprise storage systems to increase the durability, performance and capacity of flash memory and make flash a cost-competitive alternative to high-performance disk drives. The following chart shows the bit cost of Hitachi Accelerated Flash storage for a 1.6 TB flash module drive, compared to high performance 146GB 15K disk, SLC SDD, and MLC SSD.
