Yes, your Cisco network will work just fine with HP gear: here?s the proof
By John Gray, Data Center Marketing Lead, HP Networking
One thing that I often come across when I?m out there talking to network leaders is the idea that you can?t slot HP gear into a Cisco-based data center network without causing problems. I?ve always argued that, given the bedrock reality of HP?s commitment to open standards and interoperability, this is just a misperception. And now I can share some new research that should dispel that idea for good.
