From time to time, you will find it necessary to transfer files to or from your VMware vCenter Server Appliance (VCSA) or ESXi Servers. If you are working from a Windows desktop or server, there’s no more convenient utility than WinSCP for copying files securely between Windows and Linux Systems. There are a few issues,

In this post I have created a general-purpose Best Practices guideline for VMware vSphere, including references. I base these Best Practices recommendations on my personal, and VMsources collective experience, in dealing with hundreds (if not thousands, at this point) of unique client environments over the last decade. My intent is to help VMware users of

On upgrading a cluster running on HPE Blades to vSphere 7, I had a vSAN Hardware Compatibility Warning that the Controller Driver was not VMware Certified. I had been very careful with the HCL before upgrading and I was certain that all hardware components were compatible. Turns out that I had simply gone too far

I have to confess that I have always thought of NFS for vSphere as being a second-tier choice. Even the best solutions from well known vendors using 10GbE and SSD, NFS datastores always seem to under-perform and be more problematic as compared to block-storage SAN devices. Even with the theoretical reduction of overhead per payload

In an ideal world, management would provide unlimited funding to upgrade hardware continuously! We all know that’s not going to happen! Sometimes it is necessary to prolong the lifespan of servers as long as possible, particularly when they are extremely well-provisioned devices, even by today’s standards! Such is the case with our HP BL460 G7

I was designing a customer vSAN deployment and I came across the guidelines and formula for calculating the required ESXi Coredump partition size: https://kb.vmware.com/s/article/2147881 Right away, I started working the formula for my customers deployment, when it occurred to me; this is WAY more complicated than it needs to be!

For years, I have dismissed Virtual Machine Hardware version as unimportant. In fact, in this very blog, I may have advocated for leaving VM Hardware Version set at 8, to maintain full compatibility with both the vSphere C# Client and the vSphere Web Client. Unfortunately, thanks to Spectre and Meltdown, things have changed. Updating your
