To serve our headquarters campus in San Jose, California, Cisco IT deployed one of the world’s largest Cisco Unified Communications Manager (Cisco UCM) clusters, with 9 pairs of subscribers and a publisher supporting this one campus. Together with these main 19-servers the campus cluster also includes Unity node servers, presence servers and management servers, for a total of 48 Cisco MCS 7845s. In June 2012, we migrated these legacy servers to virtualized machines running on Cisco Unified Computing System (UCS) servers over a single weekend. Read More »
Recently while speaking with a group of Cisco Systems Engineers about their respective Microsoft Exchange 2010 migrations the group commented on the range of engagement sizes – in terms of individual mailboxes supported – that they had implemented during the past year or so. What we learned during this discussion is the extreme scalable nature of UCS when it comes to Exchange as engagements of up to 250,000 mailboxes were successfully handled. Additionally UCS’s virtualization capabilities – with either Hyper-V or VMware -- were seen adding to the efficiency of these larger scale engagements.
If you would like to learn more about UCS and Exchange, please register to listen to our upcoming August 1st webinar – Taking the Sting out of Exchange 2010 Migrations. Also, please visit www.cisco.com/go/microsoft to learn more on Cisco UCS and how it is an optimal server platform for your Microsoft workloads.
Follow these 3 steps for preparing your network for the new Internet protocol
On June 6, currently being referred to as World IPv6 Day, several of the world’s largest ISPs and websites will permanently enable IPv6 —the next-generation Internet. With the explosive growth of Internet-enabled devices, the batch of IPv4 addresses that allows those devices to access the Internet have run out. The new Internet protocol, IPv6, provides a greater number of addresses to support more people, more companies, and more devices on the Internet. Consider this: By 2016, 39 percent of all global mobile devices could be capable of connecting to an IPv6 mobile network—that’s more than 4 billion devices.
Your current network running IPv4-based devices won’t be obsolete for some time. However, if you haven’t already started making plans for the transition to IPv6, you should. The first step you should take is determining how and when to transition to the new Internet protocol based on your business needs. For example, if you do business with others who are already on an IPv6 network, you may decide to migrate sooner rather than later.
Once you’ve made that decision, you can follow these steps for preparing your network for IPv6.
“If you build it, they will come” is one of those cliches that have been proved wrong over and over again throughout history. Cities, railway systems, buildings, airports, luxury residents and other such structures have been built, but barely or ever used. There are many interesting reasons for such failures -- cost, location, convenience, surrounding dependencies to name a few, but all of these boiled down to some aspects of planning or lack thereof.
It is always fun to build something, say for example, a new Cloud infrastructure. Ok, I am sure you saw this Cloud association coming ! With all the technology and tools available to us, building a Cloud environment to meet our business needs is a challenging but interesting venture. Once this infrastructure is built, now what ? It is one thing to have a kick-”donkey synonym” state-of-the-art Cloud Data Center, but a whole different ball game to actually put users on it ! This is what I want to focus on, the “..they will come” part.
For most enterprise environments applications and data have evolved over time and it’s fair to state that they have a very complex dependency model. At the same time, the network, servers, storage and other Data Center elements have also evolved. Cloud service providers, regardless of what flavor of Cloud (Private/Public/XaaS), will have to think about how to interface the new Cloud environment with existing, often legacy environments.
Migrating and on-boarding tenants and applications from an existing system to new Cloud environment is not an easy process. If this is not thought through and diligently planned, then you run the risk of a Cloud environment under-utilized or idle.

The business world’s rise to the cloud has been dramatic and increasingly rapid. From an initial attitude of vague interest mixed with trepidation, organizations have begun to embrace the transition in a big way. Some are already realizing the expansive benefits in costs, efficiency, and innovation that come with this game-changing technology.
To keep with the pulse of cloud migration, Cisco initiated a series of roundtable discussions two years ago. The philosophy of each meeting was to bring together 10 to 20 decision makers from a variety of enterprises, midsized businesses, and government agencies. So far, we’ve held 15 of these discussions across North America. In addition to providing a unique opportunity to share our thought leadership, these sessions provide an ideal forum for hearing our customers’ thoughts on cloud: the benefits, the inhibitors, and even a few war stories. In the end, however, it is the advantages of cloud that spark the most contagious conversations.
Here are some of the key trends that have emerged from two years of discussions:
