Count virtualization as another boost to the fortunes of Fibre Channel SANs, according to a new report from IDC.
Far from being blown away from lower-cost rivals like iSCSI, it seems that virtual servers thrive on SAN connectivity, so many firms that were relying on direct-attached or internal storage in the pre-virtual days are in need of a high-level interconnect with enough overhead to accommodate growing data demands.
iSCSI does fill the bill in many instances, but many organizations are still leery of placing all that storage traffic on their Ethernet infrastructure.
Continued reliance on Fibre Channel, however, will require some additional developments. First, new switches will need to better handle some of the more advanced features available on the latest virtualization platforms, such as live migration between virtual servers. There also needs to be greater cohesion between the virtual layer and the SAN to better manage tasks like data protection and load balancing.
