This evening I had a cool GoToMeeting with Tintri’s David Friedlander and VP of Engineering Pratik Wadher. They showed me their new Tintri VMstore, it’s the first VM aware storage system. The VMstore T440 is an 8.5 TB hardware appliance that is designed from the ground up for hosting virtual machines through 10 GigE NFS.
Tintri uses virtual machine abstractions. VMs and virtual disks in place of conventional abstractions such as volumes, LUNs or files. This allows the VMstore to measure and control I/O performance individually for each virtual disk in the system. In effect, the only layer of abstraction in a Tintri device is the virtual disk itself. Other solutions rely on storage abstractions that create a fundamental mismatch between the storage and VM layers.
I’m very impressed by their appliance, hundreds of VMs in 4U - An intelligent hybrid flash and disk architecture provides enterprise flash performance at disk prices.

Debunking the myth of Using Private VLANs to prevent VLAN exhaustion
Using Private VLANs doesn’t consolidate the number of VLANs used or does it? If you want to add security between virtual machines on the same subnet without exhausting VLAN number space, VMware advises to use Private VLANs. Private VLANs are an excellent way to provide layer 2 network isolation between servers in the same subnet. In this video you will learn that using Community Private VLANS doesn’t consolidate the number of VLANs used. On the other hand, when using Isolated Private VLANs you won’t exhaust the number of available VLAN IDs.

My VMware Certified Professional 4 - Desktop (VCP411-DT) Beta Exam Experience
This morning I’ve taken the VCP4‐DT Beta Exam. The final VCP4‐DT exam is a core component of the VCP4‐DT certification. The certification requires a passing score on the exam. The VMware Certified Professional (VCP4) and the VMware Certified Associate – Desktop (VCADT) certifications are pre‐requisites.
The VCP4‐DT certification is a requirement for the upcoming (live lab?) VMware Certified Advanced Professional: Desktop (VCAP-DT). Note: Unlike the other VCAP certifications, VCAP‐DT is not required to pursue the VMware Certified Design Expert (VCDX) certification.
The VCP4‐DT VMware Certified exam tests potential VMware Certified Professional ‐ Desktop (VCP4‐DT) candidates on their skills and abilities monitoring and managing a View 4.5 environment. Successful candidates demonstrate mastery of these skills and abilities.
The beta exam consists of 100 questions and a short pre‐exam survey consisting of 7 questions. The questions are fair but certainly not easy. Although there was a very time short notice, I had about a week to prepare for the exam. As a VMware Certified Instructor, I have access to the instructor training guide for the View 4.5 Install Configure and Manage training. I’m glad I went through it again, the training is well aligned to the exam. I also recorded a VCP-DT Prep Video – Installing the VMware View Composer which actually contains a few interesting topics. Besides that Mark Benson did a great job with his video about The VMware View 4.6 Security Server and PCoIP.
Conclusion: Don’t take this exam for granted - you have to know your stuff and have been around in a View environment. You don’t learn troubleshooting by reading a book or watching a cool Sloef video :-) True troubleshooting skill comes from attention to detail and experience.

VCP-DT Prep Video – Installing the VMware View Composer
While I was prepping for my upcoming VCP-DT (beta) exam, I couldn’t resist recording a new video and here it is. The VMware View Composer, a key component of VMware vSphere 4.6, is tightly integrated with VMware View Manager to provide advanced image management and storage optimization. VMware View Composer reduces storage requirements for virtual desktop machines by up to 90 percent and enables organizations to more effectively manage their desktop images.
