Time to move away from HPE Software

If you are still using HPE Software, you should actively plan to migrate away. The recent divestiture does not look good to me – I think existing customers are going to get soaked.

HP NNMi 10.00 Released

HP NNMi version 10.0 has been released. This is a good release, with many usability enhancements. I’m pleased to see continued development, as the future nirvana of all-powerful software defined networks hasn’t quite arrived yet.

NNMi – replacing LDAP SSL Certificate
