Migrate data without mistakes

Moving data from one array to another, or from one tier of storage to another, is a tedious process that's slowly becoming more automated. With storage capacity growing at 50% annually, an unending cycle of technology refreshes, server and storage consolidation, and data classification is driving the need to move data from one tier of storage to another or from one array to another. Data migration has become a way of life for storage administrators. In a perfect world, you would use automated tools to migrate data. Yet data migration is too often done manually: an administrator takes the system offline, backs it up to tape, installs the new array and recovers the data to its new location. A complicated data migration may include 50 or more steps, and take a night or even a weekend to perform. For businesses operating 24 hours a day, 365 days a year, this is simply too long to have a system down. "Downtime is costly; it costs me $30,000 an hour. That's not really that large an amount, but not having to take the NetApp filer out ...

  • 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.
