One of my favorite books is The Pillars of the Earth by Ken Follet, I’ve read it and reread it many times and each time I read it I get something new out of it. With so many good books out there it seems silly to reread a book, especially a very long book. I think what it is, is that the story is so good, the characters so compelling that I don’t want to leave them and when I’m finished with the book I miss them. Fortunately the book was made into a mini-series that I enjoyed and brought a nice visualization of the story. I also think the mini-series may have attracted a new set of readers in the viewing audience.
New audiences come with new methods of distribution for the same, similar or different presentation of an already published work. With the intent to reach a new audience I am republishing a UCS XML API focused blog from another blog site on Cisco Developer Network UCS Section. I wrote this blog in April 2010, but the methods utilized seemed to flow from my prior entries on this site.The previously published blog has references to other blogs on the on the Cisco Developer Network site in the Cisco UCS section.
The previous blog…
Last time I wrote about using telnet to connect to the UCS Manager XML API as a way to introduce the API and show it’s lack of complexity. Now I don’t expect anyone to write an application that uses telnet to manage a UCS system, I just wanted to get across that if text, XML structured text, can be pushed across an open port to the listening API process on the UCS then it doesn’t matter how the push is done.
However telnet is not very practical, so I thought I would write about curl and xmlstarlet (xmlstarlet referred to as xml in this entry). curl is used to handle the request and response cycle with the UCS and xml is used to process the XML response. In some of my early scripts I used sed and awk to “parse” the output. I say parse but it was more pattern matching; by the way sed and awk are great tools, but maybe I’m partial to them because I’ve been around for a while. The reason I started with curl, sed and awk was not because I lacked XML experience but because I wanted to appeal to the administrators out there and show that XML experience, while beneficial, is not specifically needed.

In an earlier part of my career I learned the extreme importance of Workload Automation, aka Job Scheduling. Workload automation is the oldest IT technology on the planet coming from the need to schedule jobs on an IBM Mainframe. Job Scheduling has evolved from driving JCL (Job Control Language) to Workload Automation where the Scheduler stitches together batch and real time activities across mainframes, proprietary OS systems, x86 systems, applications (both packages and commercial off the shelf such as SAP or Oracle or Informatica) and now web service enabled applications whether they be onsite or in the cloud. Walk into the operations center of any data driven company and you will see multiple screens where operations are monitoring the state of these jobs. Why are they so critical? Over 50% of all transactions that occur on this planet are batch in nature. They are scheduled based upon specific times or based upon dependencies being met. These workloads can be a complex and interrelated set of activities. Effectively these job streams are the business processes that drive modern enterprises.
Without these jobs companies don’t get information (and large amounts of it) in the right place at the right time. Most companies today could not close out their financial quarters without enterprise schedulers to move data from their disparate systems into a consolidate place for either the general ledger to close out or for a critical Business Intelligence report to run to drive placement of the correct product into the specific physical location to serve the global economy. Workload automation tools open and close stock exchanges and process all the transaction data from trades. They also drive compliance checks. This is important stuff for the global economy! This was my realization in touring key operations centers and realizing that half of the big monitors were covering the movement of batch data in the enterprise.

It’s actually BOTH, which I’ll get to in a minute… First, are you going to VMware Partner Exchange? Planning out your agenda for next week? If so, you’ve got some great opportunities to learn about VXI with VMware. Before we get to the good stuff, I want to highlight something that we often get asked, namely the difference between VXI and desktop virtualization, ie: the title of this post! Read More »

Next week is Cloud Connect in Santa Clara and Cisco’s Cloud Software group will have a big presence.
While we have plenty to talk about on how Cisco is helping customers build their cloud, we also want to listen to our customers plans and needs. We are bringing some of our engineers and architects so you can engage directly with them. There are three things you can see next week.
CITEIS – Cisco’s, in production, private cloud.
See how it was built, the results in agility and cost, and best of all see a demo. Not a fake demo but the real thing.
Of course, we will also be showcasing our award winning cloud automation software, Cisco Intelligent Automation for Cloud (CIAC) (formerly newScale and Tidal), which provides the self-service catalog and orchestration to our private cloud

It’s clearly evident from the evolution of technology that the “need for speed” seems to be deeply embedded in human nature. Reflecting back without going too far back in history, the horse and buggy was the main mode of transportation, unfortunately not fast enough. So we invented the locomotive, automobile, airplane, fax machine, e-mail, and mobile phones with text messaging among the hundreds of other inventions to fulfill our need to do things faster.
Being a networking guy, I might be biased, but I see networks as the new frontier for speed, especially now that we are a media/information driven society. It wasn’t long ago that a 10Mbps shared Ethernet LAN and 56kbps WAN links were considered fast (showing my age here). However, every time faster networking speeds were introduced, newer applications quickly consumed the capacity driving the need for even higher speeds.
Over the years we’ve seen Ethernet speeds increase in increments of 10x starting with 10Mbps to 100Mbps to 1GE and 10GE and now, we’re again at another speed inflection point -100Gigabit Ethernet! This week Cisco added to our 100GE router portfolio (CRS and ASR routers) with the announcement of a 100GE M2-Series module for the Cisco Nexus 7000 Series switches. Along with the 100GE module, we also announced a 40GE M2-Series module for the Nexus 7000 and a 40GE module for the Catalyst 6500.
