Today I was preparing a new blade chassis in an existing vCenter environment. After applying the predefined Critical Host Patches baseline (default task for new hosts), the hosts would not reconnect to vCenter.
Turns out VMware decided to disable SSLv3 for ESXi 5.5 Update 3b and higher, because of the POODLE vulnerability. The dependency is clearly stated in the release notes and in the VMware Product Interoperability Matrix below. (more…)
The other day we were messing around with VMware vRealize Operations Manager a.k.a. vRops. My customer wanted to have a clear overview of virtual machines being over- or undersized.
I like to use default views within vRops and adjust them to my needs. The same goes in this example using the predefined Virtual Machine Rightsizing CPU, Memory, and Disk Space view. As I was tuning this view to our liking, it only showed the virtual machines that were oversized.
I am just as curious about undersized virtual machines, but those were missing. I was expecting to see 4 virtual machines instead of 2…
Maybe it’s just me, or me still in ramping-up mode after a short vacation, but I missed the filters that were applicable to this view. Even though the description says it all… 🙂
List of Virtual Machine Rightsizing CPU, Memory, and Disk Space. This list is filtered to only VMs that are oversized and are currently powered on.
A while ago I finally had some attention for my much beloved data. I gave some thought on how my data would be safe if disaster would struck, like my Synology NAS catching fire. Or worse, my house…
So when I speak of ‘my beloved data’, I am talking about:
I could live with my homelab data being lost. I would not be a happy man, but a complete homelab reinstall would be possible without any backup. However, if one can avoid the loss of data, one should. 🙂
More important however, are my personal documents and my photos/videos. Those are invaluable to me! I wanted to make sure that all this data is centralized on my Synology NAS and I have the requirement for an off-site backup. The off-site backup would have to be affordable while growing in GB’s. The RTO would not matter that much as long as I’m able to recover the data.
Also, I would like to reduce the number of cloud storage solutions (Google Drive, Onedrive, Dropbox) and their associated clients.
The diagram below shows the setup I came up with:
