Putting Some VMware ESX Storage Tips Together | Part 2
Making an internal SATA HDD into an RDM for a Windows-based VM

In the first part of this post I showed how to use a tip from Dunacn Epping to fake VMware into thinking that a HHDD (Hybrid Hard Disk Drive) was a SSD.
Now let's look at using a tip from Dave Warburton to make an internal SATA HDD into an RDM for one of my Windows based VMs.
My challenge was that I have a VM with a guest that I wanted to have a Raw Device Mapping (RDM) internal SATA HDD accessible to it, expect the device was an internal SATA device. Given that using the standard tools and reading some of the material available, it would have been easy to give up and quit since the SATA device was not attached to an FC or iSCSI SAN (such as my Iomega IX4 I bought from Amazon.com).
For the device that I wanted to use, the device name was:
Then the next steps were to update an existing VM using vSphere client to use the newly created RDM.
Hint, Pay very close attention to your device naming, along with what you name the RDM and where you find it. Also, recommend trying or practicing on a spare or scratch device first, if something is messed up. I practiced on a HDD used for moving files around and after doing the steps in Dave's post, added the RDM to an existing VM, started the VM and accessed the HDD to verify all was fine (it was). After shutting down the VM, I removed the RDM from it as well as from ESX, and then created the real RDM.
As per Dave's tip, vSphere Client did not recognize the RDM per say, however telling it to look at existing virtual disks, select browse the data stores, and low and behold, the RDM I was looking for was there. The following shows an example of using vSphere to add the new RDM to one of my existing VMs.
In case you are wondering, why I want to make a non SAN HDD as a RDM vs. doing something else? Simple, the HDD in question is a 1.5TB HDD that has backups on that I want to use as is. The HDD is also bit locker protected and I want the flexibility to remove the device if I have to being accessible via a non-VM based Windows system.
Could I have had accomplished the same thing using a USB attached device accessible to the VM?
Yes, and in fact that is how I do periodic updates to removable media (HDD using Seagate Goflex drives) where I am not as concerned about performance.
While I back up off-site to Rackspace and AWS clouds, I also have a local disk based backup, along with creating periodic full Gold or master off-site copies. The off-site copies are made to removable Seagate Goflex SATA drives using a USB to SATA Goflex cable. I also have the Goflex eSATA to SATA cable that comes in handy to quickly attach a SATA device to anything with an eSATA port including my Lenovo X1.
As a precaution, I used a different HDD that contained data I was not concerned about if something went wrong to test to the process before doing it with the drive containing backup data. Also as a precaution, the data on the backup drive is also backed up to removable media and to my cloud provider.
Meanwhile, time to get some other things done, as well as continue looking for and finding good work a rounds and tricks to use in my various projects, drop me a note if you see something interesting.
Ok, nuff said for now.

As we enter a new year, it is time to look back over the past year and resolve to improve upon it. In 2014, we will see more service providers resolve to add more personalization in enterprise technology. Below are seven predictions about what will drive this trend toward personalization.
IT organizations face a growing demand for faster innovation and new applications to support emerging opportunities in social, mobile, growth markets, Big Data analytics, mergers and acquisitions, strategic partnerships, and more. This is great news because it shows that IT continues to be a key stakeholder in delivering business service innovation. However, it also means that IT must deliver new innovation despite flat budgets, while maintaining existing services that grow more complex every day.
Cloud computing is transforming the way businesses think about and leverage technology. As a result, the general understanding of cloud computing has come a long way in a short time. However, there are still many misconceptions about what cloud computing is and what it can do for businesses that adopt this game-changing computing model. In this exclusive Q&A with Cloud Expo Conference Chair Jeremy Geelan, Rex Wang, Vice President of Product Marketing at Oracle, discusses and dispels some of the common myths about cloud computing that still exist today.
Despite the economy, cloud computing is doing well. Gartner estimates the cloud market will double by 2016 to $206 billion. The time for dabbling in the cloud is over! The 14th International Cloud Expo, co-located with 5th International Big Data Expo and 3rd International SDN Expo, to be held June 10-12, 2014, at the Javits Center in New York City, N.Y. announces that its Call for Papers is now open. Topics include all aspects of providing or using massively scalable IT-related capabilities as a service using Internet technologies (see suggested topics below). Cloud computing helps IT cut infrastructure costs while adding new features and services to grow core businesses. Clouds can help grow margins as costs are cut back but service offerings are expanded.

What do you get when you combine Big Data technologies….like Pig and Hive? A flying pig? No, you get a “Logical Data Warehouse.” In 2012, Infochimps (now CSC) leveraged its early use of stream processing, NoSQLs, and Hadoop to create a design pattern which combined real-time, ad-hoc, and batch analytics. This concept of combining the best-in-breed Big Data technologies will continue to advance across the industry until the entire legacy (and proprietary) data infrastructure stack will be replaced with a new (and open) one.
While unprecedented technological advances have been made in healthcare in areas such as genomics, digital imaging and Health Information Systems, access to this information has been not been easy for both the healthcare provider and the patient themselves. Regulatory compliance and controls, information lock-in in proprietary Electronic Health Record systems and security concerns have made it difficult to share data across health care providers.

Everyone talks about a cloud-first or mobile-first strategy. It's the trend du jour, and for good reason as these innovative technologies have revolutionized an industry and made savvy companies a lot of money. But consider for a minute what's emerging with the Age of Context and the Internet of Things. Devices, interfaces, everyday objects are becoming endowed with computing smarts. This is creating an unprecedented focus on the Application Programming Interface (API) as developers seek to connect these devices and interfaces to create new supporting services and hybrids. I call this trend the move toward an API-first business model and strategy.
We live in a world that requires us to compete on our differential use of time and information, yet only a fraction of information workers today have access to the analytical capabilities they need to make better decisions. Now, with the advent of a new generation of embedded business intelligence (BI) platforms, cloud developers are disrupting the world of analytics. They are using these new BI platforms to inject more intelligence into the applications business people use every day. As a result, data-driven decision-making is finally on track to become the rule, not the exception.
