WMUG changes - you better download/review your licenses

✇homelab.
／u／kY2iB3yH0mN8wI2h

Today, in Barcelona at VMware Explore, Broadcom announced a new program that gives Advantage members an exclusive path to VCF and VVS personal use licenses.

This program will alter the current path to EVALExperience within VMUG Advantage. Read the Broadcom press release here. As an Advantage member we want to ensure you have the details on this change.

* November 30, 2024: This is the final date to access EvalExperience licenses through the current VMUG Advantage process. The Kivuto/OnTheHubplatform will be available until this date, allowing you to download any remaining licenses.

* December 1, 2024: After November 30, the current process for downloading EvalExperience licenses will end, and licenses will no longer be automatically provided through VMUG Advantage.

* Future Access To Licenses: VMUG Advantage members will have access to a new pathway for obtaining VCF and VVS non-production, personal use licenses through Broadcom’s VCP program. More details on this program will be shared as they become available.

As a current VMUG Advantage member if you wish to access EvalExperience Licenses before this change, ensure you download them by 11:59 PM CST on November 30, 2024. Any licenses downloaded by this deadline will remain valid for 365 days.

Closet airflow suggestions

Currently I have converted two of hall closets in an apartment to my "datacenter". Everything is working fine, airflow is good and nothing major.

However I'm using one intake and one exhaust fan per closet, currently AC Infinity Airframe system. This works but two of the displays have died and the noice level required is still quite high. So instead of running my equipment on high speed, this have moved to the AC Infinity fans.

Now I'm considering moving to AC Infinity rack system. I had in-rack 19" fans previously, they actually worked quite well but only had one fan speed. But the noice was moved from outside of the rack to the inside.

Do you all think it's a good compromise to move to something like the Cloudplate (https://acinfinity.com/rack-fans/) instead?

I'm thinking about two 3U intake fans and two exhaust fans per closet. All these could run at their own settings allowing me to control the flow better based on current load.

I have spread the load between the two closets to at least in theory spread the heat/air-flow.

I'm not running anything crazy (I think...)

My Brocade 300 FC switch is dead..

I'm trying to get some assistance but most of the KB's are behind a brocade wall (I Have a user account and have used it in the past but now nothing works..)

Anyone where that can help me troubleshoot? I have replaced the fans with compatible fans on eBay and they work and spin up, but when I try to login into console I just get a lot of errors :(

If you use GPU passthrough - power on the VM please.

If you use GPU passthrough - power on the VM please.

I have recently installed outlet metered PDUs in both my closet racks. They are extremely expense but where I work we take power consumption extremely seriously and I have been working power monitoring so I tough I should think about my homelab as well :)

PDU monitoring in grafana

The last graph shows one out of three ESXi hosts (ESX02) that has an Nvidia GTX2080ti passed to a Windows 10 VM. The VM was in OFF state.

When I powered on the VM the power consumption was reduced by almost 50% (The spike is when I ran some 3D tests just to see how power consumption was affected.. )

So having the VM powered-off results in ~70W of idle power.. When the VM is turned on and power management kicks in the power consumption is cut almost in half..

I actually forgot I had the GPU plugged into one of my ESXi hosts (Its not my main GPU and I have not been able to use it well as Citrix XenDesktop (That I've mainly used) works like shit on MacOS :(
