Networking analyst Jon Oltsik of
Enterprise Strategy Group told eWEEK
that this collaboration between Cisco and Microsoft "gives Cisco the
opportunity to do the kind of bundling that it does in the VMware space. It's
got vBlocks (pre-configured Cisco-EMC unified data center systems) and the
NetApp-VMware packages (both for vSphere), but it can now do the same type of
thing with Hyper-V in the Microsoft space.
"It goes beyond just the UCS. With
Microsoft now, there's tight integration into the virtual network."
Mike Spanbauer of Current Analysis told
eWEEK that "while VMware may
hold the dominant share for virtualization platforms, Microsoft is No. 2 and
clearly has aggressive plans to expand its virtual 'footprint' in the
enterprise. Cisco, in turn, recognizes the value of providing well-integrated
solutions, regardless of the application vendor, and is investing to ensure
customers' needs are met-regardless of the virtual platform choice.
"Specifically, in order to manage
a virtual machine, you must first see and follow it," Spanbauer said. "This
can be accomplished with either the platform's virtual switch mechanism or
through another vendor's. Cisco has a solid virtual switching story."
- Improved visibility, control and operational flexibility for Hyper-V environments; full security control in a virtualized environment consistent with a Cisco physical network.
- Policy enforcement, automated provisioning and diagnostics are available; these help to rapidly deploy virtual workloads in Windows Server Hyper-V environments and scale to very large data centers.
- When working with Microsoft System Center Virtual Machine Manager (VMM) management tools, the Virtual Switch helps network, virtualization and server administrators gain efficiency in managing multitenant and mobile virtual environments; it also helps obtain accurate, real-time data for troubleshooting of virtual environments.
- Through integration with Cisco's security software (Virtual Security Gateway and Virtual ASA), application optimization software (Virtual Wide Area Application Services) and network monitoring software (Network Analysis Module), the Virtual Switch provides virtual machine-level security for multitenant environments.
