Satellite Tracking using Astronomy Goto Mount

Recently, I reviewed the video by K4WOF https://www.youtube.com/watch?v=kpgV8P6ocLE  and was motivated to build my own satellite tracking mount. Satellite operations are considerably easier if satellite tracking is automated so that satellite passes can be focused on radio work. Somewhat comically, automated antenna tracking looks exciting and generates community interest in our amateur radio activities. I have to apologize as mistakes were made by me as I came up to speed with satellite operations. A shout out to Jason N8PDX for invaluable feedback.

VR is free to anyone running Essentials Plus and is deployed as an appliance in OVF format.

Together with VMware’s Site Recovery Manager (SRM), comprehensive business continuity and disaster recovery plans be can built. vSphere Replication replicates at the VM level and does not rely on any underlying store replication technology. SRM can also interface directly with storage replication technologies using Storage Replication Adapters (SRA). A combination of both VM based replication (VR) and array based replication (SRA) can be created in SRM.

This post focuses on the use of VR for backup…

VSAN and vSphere 6.5…

There is a not so nice feature in vSphere 6.5 which makes VSAN explicitly dependent on vCenter. It is detailed in the release notes but easily overlooked… http://pubs.vmware.com/Release_Notes/en/vsan/66/vmware-virtual-san-66-release-notes.html

Fixed in the latest update of vSphere/vCenter, but just be aware of the following steps before bouncing vCenter for maintenance or upgrade…
