Greening the Data Center: How Server Virtualization Makes Next Generation Data Centers More Energy Efficient

August 5, 2013 — by Lior Cohen2

Let’s recall exactly how server virtualization started and what it’s all about:

In the late 90’s, a company named VMware developed hypervisor technology, and as much as it had immediate appeal, not too many people really understood it and only a select few believed there was a business value associated with the technology.

The Growing Trend in vADC Density

October 11, 2012 — by Sharon Trachtman1

Over the past 2 years, Radware has offered virtualized ADC appliances with virtual ADC instances that can be used on hardware appliances or on general-purpose servers. During this time, we’ve noticed two schools of thought emerging on the all-important question of vADC density. The first, argues that vADC density is one of the key criteria to consider when evaluating a virtualized appliance. The second, however, claims that organizations will typically avoid utilizing density higher than 10-16 vADC on a single piece of hardware. In search of greater clarity, we went back after implementing hundreds of ADC consolidation and virtualization projects with thousands of vADCs to check and see if there were any identifiable trends in vADC density deployment.

What VMware’s Acquisition of Nicira Tells Us About OpenFlow

August 6, 2012 — by Lior Cohen6

It’s been hard to ignore all the talk around the datacenter industry since July 23rd when VMware announced their definitive agreement to acquire Nicira. Oracle followed VMware, recently announcing that it will acquire Xsigo. Overall, it seems like there are tectonic moves in the datacenter space – big vendors are stacking up. With these different acquisitions, VMware seems to be aiming at becoming the do-all virtualization software platform, and Oracle seems to be closing all the gaps in their product portfolio to offer a complete, business application optimized data center platform. Top that with the Cisco UCS idea (not new), adding Compute to their portfolio, which seems to be succeeding but still a major move in the way people buy datacenters, it truly shows how things are different than the way they used to be when HP and IBM were fighting head-to-head.

April 15, 2012 — by Nir Ilani0

Everyone’s talking about these various next-gen data center trends – and there are so many buzz-words which makes it hard to follow. So I’ve decided to pick-up the glove, and in my next blog series I will try to explain the key trends that impact the next-generation data center, see what each trend means and finally discuss how they can be addressed in the most cost-effective way.

Impressions from a Business Seminar in Vienna: Freezing Outside, Hot Inside!

February 12, 2012 — by Nir Ilani1

A couple of weeks ago, during part of my European business travel to visit our customers, I had the privilege of being invited to speak at a seminar focused on next-generation data center needs & trends at Interxion in Vienna, Austria. While the outside temperature was almost zero, the seminar was one of the best (read: fun) I’ve ever attended.

But first, who’s Interxion? Interxion is a leading pan-European provider of hosting and colocation services – which means that their end-customers own and manage their servers/network equipment while Interxion takes care of the data center space, electricity, cooling and connectivity.  They have huge, impressive operation operating 28 data centers in 11 countries and serving 12,000 customers (carriers, enterprises, content providers, mobile service providers and more).

China Rockets to the Cloud – Don’t leave your ADCs on the Ground

September 28, 2011 — by Ronen Kenig0

Last week I had a business trip to China, visiting our customers and new prospects. Our business in China is growing fast and one of the drivers for this growth is cloud initiatives. It seems to me that in China everyone is talking about the cloud, busy building data centers for the cloud or planning how to move their business to the cloud. I have no doubt that with government investment of US $154 Billion (as announced recently), China is on its way to become one of the world’s cloud hubs.

ADC Consolidation: Handle with Care

September 12, 2011 — by Ronen Kenig0

Similar to server consolidation, application delivery controller (ADC) consolidation can provide significant benefits to the data center. These benefits include higher utilization of existing ADC infrastructure, reduced ADC hardware costs and significant savings of operational costs such as power consumption, rack space and annual service costs.

However, ADC consolidation presents significant challenges and risks that must be addressed before initiating an ADC consolidation project.

Application Delivery Provisioning in the Virtual DC – What is it and Who Needs it?

August 29, 2011 — by Eitan Bremler0

Have you ever wondered how much time and effort it takes you to configure your application delivery controller (ADC) whenever you need to provide application delivery services to a new rolled out application? You need to get the configuration correct, then do the pre-testing, then the actual production deployment…and this cycle happens even if you only added a new server to your application to support more users.
