I was messing around with PowerCLI and the real-time statistics to collect the IOPS used by virtual machines/virtual machine disks in my my home lab. Virtual disk performance counters are available in the real-time performance stats but at the default statistics level, Level 1, with the IOPS statistics are not rolled up into the daily, weekly, monthly, or yearly statistics. I put together a PowerCLI script, collect-iops.ps1, to collect the real-time samples.

Very handy! @lamw has put together an automated lab deployment script which will deploy a 3 host nested vCenter/ESXi/VSAN/NSX Lab. It supports vSphere 6.0 Update 2 and vSphere 6.5. The scripts provide a fully deployed and ready to use lab in under an hour! A full write up and links to the scripts can be …
In a two node SimpliVity deployment there is no requirement for 10 GbE switching. The SimpliVity nodes are directly connected to provide connectivity for the SimpliVity Data Virtualization Platform (DVP) between nodes. As the environment grows adding addition SimpliVity nodes or compute nodes may be required. This requires 10 GbE switching for SimpliVity Storage traffic between SimpliVity nodes within the same datacenter and/or between SimpliVity nodes and compute nodes.
With the efficiency SimpliVity’s Data Virtualization Platform (DVP) brings to data with deduplication, compression, and optimization SimpliVity customers often need to scale compute before they need to scale storage. As long as the SimpliVity environment is capable of providing the storage capacity and performance required the compute resources can be scaled using what we call compute nodes.
Of course the first must have PowerCLI reference was the first edition of the VMware vSphere PowerCLI Reference book which has had a spot on my desk for the last couple years and I refer to it often. I recently picked up the 2nd Edition of the book and it has now taken the 1st …
Finished up another successful vSphere 6 Install Configure Manage class at Tidewater Community College last week. Time to re-provision the lab environments to get things ready for the next class.. This is a PowerCLI Script I put together to help automate the lab deployment for TCC VMware IT Academy classes.
