Guest I/O Profiling – Survey Results

A month ago I posted a survey revolving around guest I/O workload characterization. The survey consisted of five questions (I wish I would have included a sixth) that asked respondents about their experience with profiling the I/O that goes to and from the guest VM to the storage subsystem. Let me tell you why this data is important: simply, knowing …

Guest I/O Workload Characterization – A Survey

As I get deeper into the design aspect of all things vSphere I have started to realize that workload characterization is a key competency when it comes to right-sizing every aspect of your design. When characterizing the I/O workload of existing virtual workloads, there aren’t too many tools available (that I’m aware of) to accomplish this task. The two tools …

PernixData Flash Virtualization Platform (FVP): The best idea you never had

PernixData, who recently came out of stealth mode, has introduced a product that will change the way you think about SSDs and server-side caching. PernixData was founded by Poojan Kumar (Oracle Exadata) and Satyam Vaghani (Mr. VMFS!), so lets just say PernixData knows a thing or two about storage. What is Flash Virtualization Platform (FVP)? FVP promises to bring you, …

Setting Perennial Reservations for MSCS with EMC CX/VNX Arrays

The customer wanted the same level of availability and redundancy in the virtual environment that they had in the physical …

Jumbo Frames and Multi-NIC vMotion Performance over 10Gbe – Part 2

A week ago I wrote a post as sort of a follow-on to Chris Wahl’s post on performance gains (or lack thereof) using jumbo frames for multi-NIC vMotion. A fellow blogger, Josh Odgers (blog / twitter), posted a comment stating more testing with the same workloads across tests would be interesting to see. In my previous testing I performed 3 …

Jumbo Frames and Multi-NIC vMotion Performance over 10Gbe

Chris Wahl recently wrote a blog post titled Do Jumbo Frames Improve vMotion Performance? Chris was doing these tests using a 1Gbe network and the results indicated that you get slightly better performance by NOT using jumbo frames. There were a few comments and questions regarding what this would look like if you had a 10Gbe infrastructure. I also had …
