Deploying Dual-Stack IPv4 and IPv6 Networks
Doing an IPv6 implementation project does not involve tearing down an aging IPv4 network and replacing it with a new IPv6-enabled network. Instead, the IPv4 and IPv6 networks will run in parallel in what the industry calls a "dual-stack" network. But IPv4 and IPv6 are so significantly different in design that network management tools designed for an IPv4 network may not work the same in an IPv6 environment.

Time to Reconsider the Data Center
As enterprises push out data centers into cloud-based computing and virtual applications, traditional data center planning and practices haven't necessarily kept pace. Is it time to reshape definitions of classic brick-and-mortar data centers into a new computing concept with different performance and total-cost-of-ownership expectations? If nothing else, the business cases now driving data center services are beginning to demand it. "As a global organization, we know that we must not only provide 24/7 IT, but also enterprise-strength IT support on a follow-the-sun basis," said John Heller, CIO of Caterpillar.

Rapid Backup And Retrieval With Riverbed's Whitewater
Cloud storage brings cost effective offsite backup and retrieval capabilities to small and midsize businesses, but using cloud storage as an external disk is not as effective as it seems, particularly as the data set grows. It takes time to send and retrieve files to a cloud storage provider and often means using another set of tools to do so. Riverbed's Whitewater appliance makes the cloud storage appear as a backup target and balances the competing needs of speedy read/writes and long-term bulk storage. Using a combination of local file caching and deduplication with cloud storage replication, IT gets the best of both worlds.

Riverbed's Granite Virtualizes Branch Office Storage
February 10, 2012 9:00 AM
Posted by Howard Marks
When Riverbed and others brought WAN acceleration to the market around the turn of the century, many of us hoped that with WAN acceleration we could pull the servers, and the headaches they cause, from branch offices. Unfortunately, many organizations found reasons to keep servers in the branches. Riverbed's new Granite appliance allows organizations to keep servers in their branch offices while eliminating many of the headaches through what Riverbed's calling Edge Virtual Server Infrastructure.

DocuSign Does Android

One of the great promises of the mobile device explosion is increased productivity. But productivity is in the eye of the beholder, and many mobile users still haven't caught on to the notion that you can sign documents digitally, with a legally binding signature, from a mobile device. Whether the goal is paperwork reduction or expedience, DocuSign combines the power of digital ink and a slick, cloud-enabled document-handling framework to put an end to the likes of scanning and faxing. And now, those of us with Android devices can use DocuSign, too.

dinCloud: Making a Big Impact in the Cloud
February 06, 2012 9:00 AM
Posted by David Hill
Have you reached the saturation point yet on the cloud? The endless cacophony of cloud messages seems to have transformed into white noise, where trying to distinguish and differentiate among competitive cloud offerings can leave one in either a state of decision-making paralysis or trusting that familiar vendors know what they're talking about without, perhaps, the full measure of due diligence that is appropriate. Enter dinCloud, which plans to break through the droning blather and show how its approach to cloud is different.

Scale Computing: New Twists To Scale-Out Storage For The Mid-Market
January 27, 2012 3:30 PM
Posted by David Hill
Startup Scale Computing delivers scale-out, unified storage for the mid-market, meaning users can access SAN/NAS resources from the same, scalable pool of disk storage. Scale Computing is by no means alone in doing this, but the company goes beyond just delivering storage in a box to delivering a data center in a storage box. And that is very interesting.

Thought Experiment--Forget ROI
January 23, 2012 9:50 AM
Posted by Joe Onisick
Boys and girls, today's homework assignment is a thought experiment. I want you all to put yourselves in the shoes of the CXO team making a decision to move to private cloud. There is, of course, one catch: You may not factor in ROI. We're dropping ROI because it clouds the subject (bad pun intended.) Let's skip the why-should-I-do-this-experiment; I'd of course default to,"Because I told you so."
