Watching the HP public cloud discussion has been an interesting lesson in technology and how it is supported and marketed. HP isn’t the first company to publish a bold statement ending support for a specific technology or product line only to go back and rescind it a few days later. Some think that a problem like that shows that a company has some inner turmoil with regards to product strategy. More often than not, the real issue doesn’t lie with the company. It’s the customers fault.
It’s no secret that products have a lifespan. No matter how popular something might be with customers there is always a date when it must come to an end. This could be for a number of reasons. Technology marches on each and every day. Software may not run on newer hardware. Drivers may not be able to be written for new devices. CPUs grow more powerful and require new functions to unlock their potential.
Customers hate the idea of obsolescence. If you tell them the thing they just bought will be out-of-date in six years they will sneer at you. No matter how fresh the technology might be, the idea Continue reading
A lot can change in six months — including comfort of a $40 million funding cushion, apparently. Docker Inc. raised that much with a C round in September. But the startup needs even more, so today, it’s announcing a $95 million Series D round. Yes, already. Interest in open source Linux containers is still exploding, with Docker Read more >
You may have noticed that last week, Plexxi, in partnership with PSSC Labs, announced a new solution that will change how companies install and operate new big data infrastructure. This partnership combines Plexxi’s SDN switching and control with PSSC’s high-performance servers and Cloudera Enterprise big data platform.
The Scale-out Network Comes to Big Data
We already know that the way Enterprise applications are built is changing rapidly. New applications are being written to be far more distributed and designed to scale horizontally across the infrastructure. This allows companies to easily scale performance, storage, and networking power as the application needs grow. Scale-out applications like Cloudera Enterprise’s CDH (Cloudera’s Adache Hadoop distribution) are already built to easily scale across compute and storage – meaning administrators can incrementally add new servers that add more processing power and data storage capabilities to the application. Yet the “state of the art” way to build the network is to pre-determine the total number of servers needed and to build a scale-up (2-tier) leaf/spine network. Plexxi’s network is a true scale-out network – no hierarchies, no pre-determined ceilings for number of server ports, and just a single cable to add a new switch to the Continue reading
A 'single source of truth' for IT.
Finally, it’s the blog you’ve all been waiting for! Yes, that’s right folks; the time has come to discuss the benefits of Real-Time Monitoring Tool (RTMT) in CUCM and CUC. All right, I know it’s not the most exciting subject to discuss all the topics on the CCIE Collaboration lab blueprint, but it can help you perform troubleshooting tasks in a very efficient manner. The goal for this blog is to point out a couple useful features of RTMT to give you a nice boost when tackling different lab topics.
For those that are not familiar with RTMT, it can be used to pull traces (log files) for troubleshooting in all Cisco UC servers, monitor real-time platform statistics, check syslog messages, and display a host of “Performance” parameters that can assist the engineer in gathering system information. While those are all great features worthy of our attention, I’d like to focus specifically on a new RTMT feature available in CUCM 9.x called “Session Trace Log View.” This feature is an excellent troubleshooting tool, especially when used with SIP. Essentially what this does for us is organize the traces in such a way as to provide a cohesive view Continue reading
A massive round for the security startup.
