Benchmarking with VMmark on new hardware

Bruce Herndon tries out the VMmark on new hardware.

These two different disk configurations highlight some interesting tradeoffs and tuning opportunities exposed by VMmark. The single LUN configuration utilizing six disks has the benefit of providing high disk throughput for one VM at the expense of scalability if multiple disk-intensive VMs are running. On the other hand, creating multiple LUNs provides both good predictability and excellent scaling but limits the total throughput of any single VM by providing only a subset of the hardware resources to each one. From a benchmarking perspective, the multi-LUN approach is clearly better since it results in a higher overall score.

Honestly, we have reported several benchmarks and tools being used were either beta or some of them reported results that really didn't matter. VMware is also a member of the SPEC committee but still results like these speak volumes.

Benchmarking is not about VMware is better than Parallels is better that Xen is better than whatever. It is about telling the customer to be careful when applying and deploying certain scenarios. VMware is doing a pretty good job at it.

Redhot Future Of IT Part I :Marketing yourself as IT professional

I had promised about the "RedHot IT Future Series" and so we discuss here how you should market yourself EFFECTIVELY as an IT professional in this new (and dangerous) web age! Web is the place where you're a hero today and villain tomorrow. While there are lots of professionals who are active on the web, not all are enjoying a good reputation as they got "personal" with others and got into a cockfight. The passive IT professional has nothing to lose but nothing to gain at all!

I know "marketing" might seem as a greasy term but the idea is to have the truth about you out there. You know you're a good person and your family knows that you're really smart person but the rest of the world doesn't!

So the question is how do I market myself on the web as a true "nouveau IT professional". A guy who companies will be tempted to pick up the phone as say "Hey, we wanna talk with you. Can you fly over to Palo Alto (or Guatemala or Johan…
