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! VMware actually wants you to take… Continue reading “Setting the coredump partition when using vSAN”
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… Continue reading “Virtual Machine Hardware Version does make a difference”
Invalid snapshot configurations happen. Mostly, they occur because of problems with storage arrays during snapshot creation/consolidation, but they can also occur if certain process become interrupted (like replication) mid-snapshot. The more heavily you rely on snapshots, the more likely it is you will come across a problem with snapshots. Specifically if you use a product… Continue reading “Invalid Snapshot Configuration”
Many people are under the incorrect belief that it is hardware-level firmware updates from companies like HPE and Dell that will protect our Virtual Machines from Speculative Execution Vulnerabilities. This is NOT TRUE. As far as your VMs are concerned, the VM BIOS and Hypervisor are the hardware!
As we are all aware, recent updates to Shockwave Flash caused the vSphere Web Client to crash on most browser platforms. The interim solution was to install an outdated version of Shockwave Flash, just to access the Web Client. More recently, Adobe Shockwave Flash version 126.96.36.199 was pushed out in updates to Google Chrome (and… Continue reading “The VMware vSphere Web Client is fixed (sort of – until next time)”
Over the weekend Google pushed out an update to Flash (188.8.131.52) with an update to Chrome (61.0.3163.100) and now vSphere Web Client is broken once again!
VMware Workstation Pro 14 is a 64-bit Type 2 Hypervisor that is available for Linux and Windows. As a Type 2 Hypervisor, Workstation Pro runs as an application on top of a full Operating System like Windows 10 or Ubuntu Desktop and claims compute and hardware resources from the parent OS, then allocates those resources… Continue reading “Installing VMware Workstation Pro 14”
Being successful with VMware vSphere is largely about understanding “Who’s on first, What’s on second and Idunno’s on third,” at any given point in time. This is especially true with the VMware vCenter Server Appliance (VCSA), as it presents a several new console choices to the administrator.
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,… Continue reading “Using WinSCP with the VMware vCenter Server Appliance”
I recently went looking for information on password security for the VCSA 6.0 & 6.5 and ESXi 6.0 & 6.5. Most specifically, I was interest in the number of passwords remembered, so I could define that in documentation for a client. Try as I might, I couldn’t find documentation for VCSA number of passwords remembered… Continue reading “VCSA and ESXi password security”
