Access "Replication revisited"
This article is part of the Vol. 9 Num. 10 February 2011 issue of Storage Products of the Year 2010
Once an expensive option, replication is now available in many forms and is more affordable and effective than ever. The success -- and adoption -- of replication technology can be largely attributed to advances in local-area, wide-area and storage-area networking, as well as server virtualization and cloud computing. From replicating virtual machine (VM) images for data protection and high availability to the exchange of information with cloud services, replication has proved to be the most suitable and agile data transfer and protection method in increasingly virtualized IT environments. But it's not just coincidental progress that has elevated replication's role in data management. It's as much, and perhaps more, due to changes in business requirements. For example, downtime tolerance has been shrinking. A 2010 data protection research survey conducted by Milford, Mass.-based Enterprise Strategy Group (ESG) revealed that 18% of respondents can't accept downtime for tier 1 applications, up from 8% only three years ago. Disaster recovery (DR), a prime user ... Access >>>

The end of NAS as we know it
by Tony Asaro
You've read all the predictions about how file storage will bury our data centers in a few years. How to cope? Probably not with NAS.
