Cheers and jeers for tiered storage

Tiered storage has lost some steam among Storage survey respondents in the past year. Forty-nine percent of recent respondents manage a tiered architecture vs. 68% in a similar survey conducted in early 2007. Back then, 78% of those who weren't tiering had plans to implement tiered storage. This time around, 59% plan to adopt tiered storage (46% of those within a year). In our most recent survey, users have largely upgraded to 4Gb/sec Fibre Channel (FC) for Tier 1: 62% now use 4Gb/sec FC for their top tier vs. 34% in 2007. Solid-state drives might finally be making headway, with 12% of those surveyed using the technology as Tier 0. However, tiered storage gets mixed reactions; it's "definitely not for the faint of heart," says one respondent, while another praises the concept but adds that "all aspects of management of multiple tiers could be much easier." The biggest pain point? Classifying data so that it's sent to the right tier. --Christine Cignoli

  • Migrate data without mistakes

    by  Deni Connor

    Data migrations are a fact of life. In many cases, the migration ends up being a tedious process. Automated tools can help ease migration woes. Host-based migration software takes the load off the storage array and can easily bridge the gap when migrating data between heterogeneous storage systems. But array-based migration may be preferred for technology refreshes.

  • The big crunch: Capacity grows, budgets shrink

    The brief respite storage managers enjoyed from the ever-escalating need for more disk capacity appears to be over. Respondents to our 2008 Purchasing Intentions survey say they'll add an average of 47TB of new disk capacity this year. But they'll have to do it with smaller storage budgets. And while virtualization could help respondents use their storage more efficiently, it's still receiving a cool reception.
