My VSAN lab uses Dell h310 with queue depth 25. A low VM count with low contention should be fine. I know, but they were on VMware HCL and they were cheap on eBay. While the adapters work out of the box, they had an issue – deactivating one memory channel, which I solved. Recently I found […]
Trust Relationship Between Workstation and Domain Fails – fix without double reboot
Usually it can hapend after restore operation. You restore an older VM and the Windows VM can’t authenticate with the domain because the Trust Relationship between workstation and domain fails. You can see a nice error saying that “The Trust Relationship between this workstation and the primary domain failed”. It can also happens if you restore […]
How-to Change or Disable Session Timeout in LogInsight
VMware has released Loginsight 2.0 product last week. As I’m testing the product in my lab I was looking on How-to Change or Disable Session Timeout in LogInsight. If not, I think it’s like 30 min by default or something like that. You can do it similar way that I did it in vCOPS where […]
How-to safely change from LSI logic SAS into VMware Paravirtual
VMware Paravirtual adapters were introduced back in 4.x and at the beginning there were some concerns. There were some issues if used with virtual machines that didn’t do a lot of IOPS, but that was resolved in vSphere 4.1. Otherwise PVSCSI offers 12% improvement in throughput at 18% less CPU. Today we’ll see how-to safely change virtual […]
My first look on VMware VSAN observer
After my recent installation of VSAN cluster I wanted to get some more deep information about what’s under the hood as vSphere web client itself does not give you much insights. I also wanted to see if the installation and configuration VSAN Observer performance and statistic tool is about. I already saw some posts about […]
By default VSAN does not show any VM storage policies – How to create them
When I finally accomplished my “homebrewed” VSAN cluster by checking “activate VSAN” check box and manually associated the locally attached disk drives into the disk groups, I thought that’s it, VSAN is up and running. True, but after migrating few VMs to the newly created VSAN datastore I thought hey, there should be some storage […]
Which Tool to use for cloning ESXi on USB stick
I was seeking the other day for an utility which would allow me to create an exact copy of an USB key with VMware ESXi installed. To clone ESXi installed on USB stick to another USB. I looked through the internet and tried a freeware utility that did not work (ImageUSB), but then stumbled across Clonezilla which […]
Memory Channel per Bank getting non active when using PERC H310 Contoler card – Fixed!
I had this memory problem since about a week in my lab, and while still waiting for other pieces I ordered for the lab, I didn’t really seek a solution. But tonight I received all necessary parts to be able to assembly all 3 hosts for VSAN. But there was still this problem with memory. […]
Infiniband in the homelab – the missing piece for VMware VSAN
The first time I ever touched this amazing (and cheap) network technology called Infiniband, it was a while ago when setting up a back-end storage network (without an IB switch) between two hosts. You could probably see the exploit in my article here – Homelab Storage Network Speedup with …. Infiniband, together with a short video. The HCAs […]
How-to rename VMNIC in VMware ESXi
The problem of assigning different name to your VMNIC is not new. Several sources reported NIC enumeration that occurs after applying a BIOS update, resulting a connectivity loss. But there is a way to fix it even if rename VMNIC in VMware ESXi through the UI isn’t possible. In my case it was simple a cosmetic […]
