Cisco and Microsoft roll out Windows on WAAS Networking Appliance



Posted by: David Davis
Networking, Cisco

You don’t see a lot of Cisco and Microsoft “joint announcements”. In this case, Microsoft and Cisco jointly announced a new networking appliance - Windows on WAAS. The “WAAS” is Cisco’s Wide Area Application Services initiative (read more about WAAS here). WAAS is designed to accelerate application performance to remote offices and by having Windows 2008 Server virtualized inside the WAAS Appliance, there is no need for a separate Windows Server. In this way, the WAAS Appliance (and embedded Windows Server) can provide necessary branch office services like Active Directory (AD), DHCP, DNS, and File Services.

To learn more, take a look at Microsoft & Cisco’s Joint website on Windows on WAAS.

Hyper9Hyper9 is a VMware Virtual Infrastructure Management platform. The most powerful feature is its “search engine” for your virtual infrastructure. As Hyper9 can do so much, it is difficult to describe. That is why I recommend you watch this YouTube video covering Hyper9.

If you have a VMware Infrastructure with at least 2 servers, 20 VMs, and would like to obtain one of my exclusive Hyper9 Beta program invitations, please contact me, David Davis. I will put you in contact with the Hyper9 beta program manager.

Once you see Hyper9 in action, I think you will be as impressed as I was!

I attended a webinar put on by PacketTrap network management this week. I was interested to see one of their latest features of their network management system - Perspective. The new feature is VMware Virtualization support.It works like this - PacketTrap uses SNMP to talk to each VMware ESX host system, pulling back statistics on host and guest performance. Perspective collects the following data:

  • Hostname
  • IP address
  • Operating System
  • Application Statistics
  • Services Running
  • CPU
  • VM Memory
  • Disk Usage by VM

You can download a free evaluation of PacketTrap Perspective and their virtualization features at their website.
