SAN extension, largely left for dead several years ago, shows signs of renewed growth.
According to the "2007 Enterprise User Survey on Storage Area Networks & Storage Transport Services," published this week by Heavy Reading, 136 enterprise IT managers worldwide report growing interest in SAN extension and other storage transport services (STS).
While just 16 percent of those polled are using SAN extension services now, 60 percent plan to add them within the next two years, mostly through the use of Fibre Channel over IP.
Just 21 percent of respondents reported having no plans for SAN extension, in contrast with a similar survey in 2004, in which Heavy Reading found 40 percent of 260 respondents expressing no interest.
Service providers once banked on the growth of SAN extension services over Sonet, optical wavelengths, private networks, and Ethernet connections. But deployment fell short of expectations, despite growth in online backup, hosted email, and other kinds of storage-related services.
