Successful implementations of virtualization in enterprise production networks depend less upon virtual server vendors and more upon management and security technology providers adapting their products to the new paradigm virtual environments represent, according to sessions at Interop. All server forums As more enterprise IT managers look to virtualize x86 servers in production networks, industry watchers warn that management and security technologies must also be considered before deployment. For one, virtualization will tax tomorrow’s networks as today’s tools fail to keep up with the rate at which virtual servers proliferate and network managers succumb to virtual server sprawl. With all the benefits of virtual servers — speedy roll outs, efficient resource consumption and made-to-order test environments — the network traffic that passes among virtual server instances can be lost to traditional network management and security tools, putting environments at greater risk for performance failures and security threats, industry watchers say.
