International IT services provider Sycor was redesigning the networks for one customer who had 4500 employees spread across 80 branches in addition to a headquarters and many telecommuting and mobile workers. One issue they were addressing was that this customer was having problems with one of their web-based applications. This specific app was used by just one person at each branch, but was important to the customer’s business. So Sycor engineers tuned both the app’s website as well as the central database with which it communicated.
The solution they were considering was a dedicated data terminal at each branch to work separately but in parallel with the existing network deployments. And then the customer started having problems with more applications at more branches. Something had to be done.

A key WAN optimization benefit is the mitigation on bandwidth consumption during the huge traffic burst on Mondays, when employees arrive at work and email attachments come to their mailboxes. This chart shows actual bandwidth consumption well below what applications would have required.
A few weeks back I highlighted a report from VCE about our virtual WAAS (vWAAS) WAN optimization solution running on the Vblock platform. Now comes a new case study of a vWAAS deployment at Georgetown, Kentucky-based Toyota Tsusho America, Inc. (TAI). For the Georgetown data center, TAI decided on vWAAS rather than WAAS appliances. The detailed case study is a compelling argument for virtualizing WAN optimization for improved high-availability and more streamlined operations.
“We were an early adopter of vWAAS,” says Chris Jones, TAI Manager of Infrastructure and Operations, “and we perceived value in placing WAN optimization close to the data rather than near the WAN edge. In particular, we felt we could have lower-cost high availability (HA) for WAN optimization by leveraging the Vblock HA. And we perceived operational simplicity in the event of failure, compared with replacing a physical appliance and rebuilding the cache.” Read More »

If you got the Thanksgiving week copy of Network World, you’d have seen a feature article on the testing they did on the newest Cisco Wide Area Application Services, or WAAS for short. The Clear Choice test looked at the speed and scalability of the industry’s most scalable WAN Optimization appliance – the WAAS 8541.
Below, we provide an overview of the article, list the highlights of some great testing, and show a fun video that goes through the case for WAN optimization.

Tomorrow, Wednesday November 16th, we’re having a live webcast, “Getting Rid of Repeats: How Cisco DRE Helps Optimize Performance”, going over the technical details behind the advanced caching technology in Cisco WAAS Context Aware Data Redundancy Elimination (DRE).
Show hosts Noam Syrkin WAAS expert (and recent video datasheet star) and Jimmy Ray Purser of Techwise TV fame give an “under-the-hood” review of this new Context-Aware DRE technology, as well as a look at how this and other technologies within our WAN Optimization solutions are bringing big opportunities to the enterprise network.

Dateline Barcelona, Catalonia, Spain. Citrix Summit and Synergy, October 2011
Last post I said I’d get back to you to give you, at least, my opinion of why Citrix and Cisco are partnering up. As you might have seen from the dateline above, it’s easy to find out when you get to Citrix Summit and Synergy. It has to do with the global and ubiquitous Cisco networks deployed by organizations everywhere. Citrix is doing great with XenApp (last I heard, well over 50,000,000 licenses) and is poised to do even better with XenDesktop.
