vSAN Witness Appliance 6.7 P01 on Workstation 15 (& Fusion 11)

vSAN Witness Appliance 6.7 P01 on Workstation 15 (& Fusion 11)

I haven’t posted here in a while, but I figure this is the best spot a very quick post on for this given it isn’t officially supported. With the release of the vSAN 6.7 P01 Witness Appliance, the OVA now prompts for OVF properties. These additional settings are read upon boot up, and automatically configure networking for the appliance. This streamlines the vSAN Witness Appliance deployment process significantly. I blogged about this here: https://blogs.vmware.com/virtualblocks/2019/11/07/vswa-67p01-update/ Importing pre-vSAN 6.7 P01 vSAN Witness…

Sample 2 Node vSAN Deployment Script

Sample 2 Node vSAN Deployment Script

A couple months back, I published a YouTube video of my deploying/setting up a 2 Node vSAN cluster with nothing but PowerCLI. It got a few views and several people internally at VMware asked for the source code. Well, this has been a long time coming, with my working on it on/off for a while, with the vast majority of the coding done on weekends. The foundation I wanted to keep it simple/modular, so I put together a PowerCLI module….

vSAN Stretched Clusters & VM Swap Files

vSAN Stretched Clusters & VM Swap Files

My buddy Pete Koehler put together a good post a few days ago about SPBM Policies with vSAN Stretched  Clusters: vSAN Operations: Use separate SPBM policies for VMs in stretched clusters In that post, he covers definition changes from Number of Failures to Tolerate (FTT) which was available in pre vSAN 6.6 builds, to Primary Failures to Tolerate (PFTT) in vSAN 6.6 and higher. This change was added to address the addition of local protection within a Stretched Cluster. This…

Virtual SAN 6.2 & PowerCLI – Sparse Virtual Swap files

Virtual SAN 6.2 & PowerCLI – Sparse Virtual Swap files

One of the Space Efficiency features of Virtual SAN 6.2 that is available for both All-Flash and Hybrid configurations, is the introduction of Sparse Virtual Swap files. Swap files on Virtual SAN by default, are created with the .vswp 100% reserved. In a thin provisioned/guaranteed capacity perspective, it could be said that they effectively Lazy Zeroed Thick (LZT). Virtual Swap files (.vswp) are created when a virtual machine doesn’t have a memory reservation equal to the amount of memory the virtual…

VSAN, SPBM Compliance, & PowerCLI

VSAN, SPBM Compliance, & PowerCLI

I very often tear down/distress my “lab” environment while working on docs/testing code/trying to replicate issues/etc. I was trying to recreate an issue the other day and decided to replace my vCenter Appliance. I deleted the VCSA, but left some of the other VMs, as they had some services I needed like DNS. After deploying the a new VCSA, I noticed an error in the Cluster’s Monitor tab, under Virtual SAN, specific to my VSAN objects.  The Compliance status for…
