Advanced VPLS, or ‘Cisco’s enhancements to its standards-compliant VPLS’
How many CLI commands will you need to enable VPLS? You will be pleasantly surprised. But before that, a bit of historical context:
Virtual Private LAN Service (VPLS) -- a layer 2 VPN technology providing Ethernet connectivity over packet-switched WANs, supports the connection of multiple sites in a single broadcast domain over a managed IP/MPLS network. By presenting an Ethernet interface, VPLS simplifies the LAN-WAN boundary for enterprises and enables rapid and flexible service provisioning.
Now Cisco’s Advanced VPLS (A-VPLS) adds several innovations to these table-stake benefits, advancing the VPLS technology frontier:

This is the question that VF Corporation was faced with. They are a global leader in branded lifestyle apparel with more than 30 brands, including Wrangler, The North Face, Lee, Vans, and Nautica. They sell through retailers in 150 countries and their workforce is distributed across 770 global offices. To reduce IT costs they were consolidating branch office servers and applications in centralized data centers, but this created a challenge with transferring large CAD image files.
VF Corp used a Product Lifecycle Management (PLM) application for apparel design that was hosted on servers in the branch office. The IT department wanted to deploy a new application in the data center to reduce the costs of maintaining it and give them better control over data. The designers use this application all day every day and need access to the large CAD image files that it creates, so this move presented a challenge to the WAN over which these files would have to travel.
“When we tested the new application during development, downloading images over the WAN took an average of 2 to 3 minutes, and up to 5 minutes,” says Billy Yawn, the network architect, for VF Corporation. “Before deploying the application to branch offices, we needed a WAN acceleration solution.”

In talking to many people at VMware, I’ve often heard them say,”..almost anyone can virtualize the first 300-400 servers, but after that it takes a true mix of skill, technology and planning…”. I bring up this anecdote for a couple reasons. First, I’ve heard several people ask if Vblock was only useful for the largest customers or largest deployments. It’s not a coincidence that we target a Vblock 0 (the smallest version) to begin around 300 VMs. Vblock operates differently.
The second reason is that I was reminded of this again this morning as I spoke with a large Enterprise customer. The customer is an early, existing Vblock account, with several thousand servers yet to be virtualized. Their technical staff had engaged the VCE team in weeks/months of rigorous technical debate about the inner workings of Vblock. They had already deployed just north of 400 VMs and were pushing back at a different operational model. So when I asked their leadership why they finally decided to more towards a VBlock architecture, their answer was, “We got to 400 VMs through far too many exceptions in process. We couldn’t move to the next level without a forcing function to align our business needs with our technology organization.” In essence, they needed a solution that combined the right technology with the right process. They didn’t believe they would get there with the current model.

After a slow start in 2009, storage area networks (SANs) ended strong with demand from all sectors across the globe. According to a recent industry report by Dell’Oro, the storage networking market grew 21 percent Y/Y.
Storage demand is being fueled not only by general economic recovery, but also:
- Broader and more complex deployments of server virtualization;
- Archiving and backup requirements;
- Disaster recovery and business continuance applications; and
- Regulatory compliance.
Aligning with these trends, Cisco SAN business (MDS product family) overall had a very strong calendar quarter with growth of more than 100% Y/Y. As a data point, Cisco MDS gained 13% market share and tied for #1 marketshare for Director-class switches. The market share gain was supported by several factors, including:
- Shift in customer buying trends as they acquired a DC 3.0 solution and end-to-end architecture to scale their SAN, LAN and data center interconnect (DCI); and
- NX-OS as single OS across LAN and SAN resonated well with large customers, who are now citing this as a key attribute.
It should be clear to the market that Cisco *is* committed to Fibre Channel. As another proof point, we recently introduced MDS 9148, the highest 8Gb/s density 1RU fabric switch in the market. Cisco is also investing heavily in other areas of storage networking to provide scalable SANs to enhance cloud services, security and migration services and data center interconnect solutions. Cisco continues to enable customers to upgrade to the latest technology (e.g., FCoE) without the need for forklift upgrades.
Cisco MDS 9000 switches are deployed in mission-critical data centers at the world’s largest financial institutions, automobile companies, service providers, retailers, energy companies, and healthcare organizations. You can read more about these case studies here to see why Cisco MDS is in 90% of Cisco’s top Global 3.0 accounts, has over $2.5B in cumulative revenue — and is still growing.

“The Digital Universe will double every 18 months. It is probably safe to say that the challenges for enterprise IT organizations will more than double every year.”
~ IDC Digital Universe White Paper
According to IDC, the only growth rate that hasn’t gone negative in this recession is the creation of digital information. For proof, just examine your daily routine -- you create documents, send texts and emails, all while IM’ing and capturing your “Kodak moments” throughout the day. The amount of enterprise application data created and stored per sec is growing exponentially, with no slowdown forecast any time soon. So the question is not, is there going to be less data? The question is: how will you manage, access, secure and intelligently share data?
In a combined EMC multimedia paper, IDC has defined the rate at which the “Digital Universe” expands along with the challenges IT organizations face to manage their storage needs. Analyzing the graph below, it becomes evident it is not just the “growth”, but that growth in specific data types that require focused IT attention. It is not just plain old ‘one size fits all” data management any more: IT professionals need to be savvy about life cycle management of specialized data in digital universe, which is expanding more rapidly than our universe.
