Citrix drops price of hypervisor to zero

Citrix

Citrix on Monday is making its core virtualization platform free, and announcing an enhanced partnership with Microsoft to promote interoperability between Citrix’s XenServer hypervisor and Microsoft’s Hyper-V software.

The XenServer enterprise edition, which previously cost $3,000 per server, will now be given away free and embedded in Citrix’s XenApp application delivery software, according to Simon Crosby, CTO of Citrix’s virtualization division.

The goal is to “bring the simplicity, scale and economics of the cloud to enterprise data centers for free,” Crosby says.

IBM and Juniper join in cloud strategy

IBM and Juniper provided a preview at technology that lets enterprise IT managers easily reallocate computing resources between a private and a public cloud.

Using cloud management software IBM Tivoli  and a Juniper network, the companies demonstrated a drag-and-drop interface for managing a hybrid cloud infrastructure. The console displayed virtual machines like small boxes with specific color, to show whether they were being used and what for. Identifying one application as less critical than another, he dragged several boxes from the private cloud to a public one. Then, with computing resources freed up on the private cloud, he allocated the empty boxes to the more critical function in order to meet the IT department’s service-level agreement for it.

While Nortel says it would like to proceed with the deal, it has also filed papers in U.S. and Canadian bankruptcy courts that would allow others to bid on the layer 4 to 7 technology assets and make higher, better offers, the company says.

Radware would not say how much it bid.

GNS3: How to create Frame-Relay Hub and Spoke lab

When I first came in touch with GNS3 I had not idea how to work with it. Not because it is so complicate to operate, but because I didn’t saw any software like this one. GNS3 and Dynamips make a very good job together, allowing users to emulate a lot of network scenarios with different topologies. If using only Dynamips suppose that you edit all the configuration file manually in text mode, now with GNS3 you can drag and drop devices, connections and configure them on the fly.

For today, I prepared a presentation about how you can create a Frame-Relay hub and spoke topology in GNS3, save and use it whenever you need it. This tutorial does not include the configuration of the devices which form Frame-Relay hub and spoke, but only the GNS3 lab topology. If you are looking for the tutorial on how to  configure FR hub and spoke on Cisco routers, please refer to my previous tutorial.

The GNS3 lab topology which I’ll create in the following presentation is available for download here. Take the saved lab configuration and open it in your GNS3 software. Before you use it, please have a look inside the file, as there are some lines you suppose to modify to fit your system.
