I wish you all a happy new year and would also like to start with a Home Lab update. Between the last and this update nothing has changed on the hardware-site, but on the software level.

irgNET – LAB 5.0 U1

Welcome to Update 1 of the major Update 5. In this episode, we now separate Site A from Site B completely with fire sections. Nevertheless, both data centers are connected via Fritz PowerLine adapters over the internal power grid. An honest opinion on my part: PowerLine adapters are not suitable for data center throughputs, since I can’t get more than 25 Mbit/s – however – […]

irgNET – LAB 5.0

Welcome to the 4th major update of my home lab. In this update I’ve changed the HPE Microserver Gen8 against a HP ML310e Gen8 v2, because it can have 32 GB of Memory and it contains Intel XEON E-v3 CPU just like my DL380 Gen8 servers. In this constellation I have migrated the Veeam Backup VM to the new host, plugged in the external 2 […]

irgNET – LAB 4.0 U2

Welcome to the 2nd Update, which is actually quite large, I have added the Microserver Gen8 to the datacenter again because I still want to have a business separation between the production environment and the backup environment. From this update on we differentiate the 3 node cluster as Datacenter 1 and the standalone Microserver as Datacenter 2. I installed VMware ESXi 7.0 U1 on the […]

irgNET – LAB 4.0 U1

In this update, I added another HPE DL380p Gen8 to the cluster. The Veeam backup server was virtualized and to have some security I added a USB 3.0 hard drive from Western Digital. I assigned this to the VM via USB passthrough and made it available as a backup repository. The HPE Microserver Gen8 was sold in return and Site A now has only one […]
