I am not sure how other people have learned their craft and mastered the technology they support, but for me, the learning started after the books ended. I have learned so much more from breaking something and having to find the fix than I ever did from reading a book. Back in the day around 2005, VMware released The VMTN Subscription. This was an amazing program that was something like the Microsoft MSDN subscription. These programs gave you the ability to run any of the core software packages for a year at a time for a subscription fee.
A Look At VMstore from Tintri
One of the biggest things I took away from the VMworld 2011 in Las Vegas was the all advancements within the storage part of virtualization. For me, this was the year for storage. One product that really got my attention was the new NAS appliance, VMstore from Tintri. This 3U appliance, well 5U if you count the UPC, is a single datastore with 8.5TB of usable storage. This appliance was a collaboration of some very smart individuals from different companies like VMware, Datadomain, NetApp and Sun. They put their minds together and built this NFS appliance from the ground up with specially engineered file system to work with virtualization. What makes this VM-aware appliance different from other typical storage designs is VMstore uses VM’s and virtual disks as the abstractions instead of the conventional storage abstractions, volumes, LUN’s and files that we have all been accustomed to. Each I/O request will map directly to a virtual disk all while VMstore monitors, controls the I/O and presents disk performance statistics per VM or per VMDK.
VMware Capacity Planner – A Special Use Case
I have had the opportunity to perform a few VMware Capacity Planner assessments over the years and I have been, more the most part, pretty happy with the process and the results of the reports. The assessment is really pretty straight forward. We had physical servers to the project, making sure we have proper permissions to perform all the tasks and then let the process run over an extended period of time. For the most part, this way of sampling over an extended time frame will give you a very good idea what can be virtualized and the number of hosts that will be needed.
Taking a Look at VMware Feature Limitations
Since the introduction of virtualization there has been sheer joy and excitement when having to work with application owners on the amount of resources they will need and not what they really think they want. I have seen all kinds of minimum, maximum, and special recommendation for all kinds of application over the years. In most cases, applications have evolved to be able to thrive in a virtual environment without too many limitations. Now it seems we have to verify which VMware features are fully supported with certain virtualized application also.
A Look At The Horizon
One of the cool things about attending VMworld every year is seeing what is new on the horizon and this year, ironically, there is something called Project Horizon and the first milestone of that project called VMware Horizon Application Manager. Horizon is a hosted service that will centrally manage the provisioning, access and usage of software-as-a-server (SaaS) applications while at the same time applying the companies standardized security and access controls. This will give the end users of the application the ability to use the applications via VMware ThinApp or View products to stream the application across multiple devices all with a single login. The end users will also have self-service access to a corporate store for their SaaS and Web-based applications. Managing these applications will be completely user based with no need to worry about the underlying device the software or application is running on.
Quick Recap of VMworld 2011
My pilgrimage from VMworld 2011 in Las Vegas has come to an end. In my humble opinion, this has been the week for the storage side of things with some amazing and interesting new stuff that has been released or is about to be released. There has been some really cool stuff that is working with SSD and storage.
