vSphere and NFV Tuning Considerations
VMTurbo? VMTurbo!
I have to admit I never used VMTurbo before. Heard a lot about them, read a fair deal about them, but never actually deployed their solutions myself. Let’s change that! And while I’m at it, let me write down my 2 cents on VMTurbo in this post…
So, VMTurbo first launched it’s offering in August 2010 and kept growing steadily. Their solution providing you the tools you need to utilize your virtual infrastructure at a much more efficient way compared to the resource monitoring and management your hypervisor brings you by default.
It will bring you great advantages like; less effort needed from your administrators to manually monitor and configure resources for your virtual infrastructure running your applications. And, it will create a more predicable performance for your applications! You will also benefit from being able to serve more workloads on your virtual infrastructure with less compute resources.
Quick deployment
Needless to say, I’m testing VMTurbo on a vSphere cluster. My homelab to be exact.
Using the OVA template, you should be up and running within minutes. I had to tone down the resources, used by the appliance, a notch. By default it’s willing to claim 4 vCPU’s and 16GB memory. No worries there in a common cluster, but within my lab environment, memory is scarce. 🙂
VMware Virtual SAN 6.0 benchmark
Last week I was going through ‘What’s New: VMware Virtual SAN 6.0‘, it seems like VSAN 6.0 is bigger, better and faster. The latest installment of VMware’s distributed storage platform provides a significant IOPS boost, up to twice the performance in hybrid mode. The new VirstoFS on-disk format is capable of high performance snapshots and clones. Time to put it to the test.
Disclaimer: this benchmark has been performed on a home lab setup, components used are not listed in the VSAN HCL. My goal is to confirm an overall IOPS and snapshot performance increase by comparing VSAN 5.5 with 6.0. I did so by running a synthetic IOmeter workload.
VMware has a really nice blogpost on more advanced VSAN performance testing utilizing IOmeter.
