Satellite Tracking Using Astronomy Goto Mount – Part 2

For the longest time I have been operating with MacDoppler providing VFO control and either python or node-red taking a UDP stream from MacDoppler for rotator control to send slew commands to my iOptron telescope mount every second. My initial experiences using a Goto mount are detailed here: h ttps://www.beyondcli.com/ham/satellite-tracking-using-astronomy-goto-mount/

It has been working well but it just got a little better…

vSphere ESXi Boot LUN Cloning is Unsupported

Two KB’s document the issue but just a heads up if you have been cloning boot luns to deploy ESXi, you are going to have a really bad day…

vSphere Replication 8.x

vSphere Replication (VR) is VMware’s replication tool to replicate VM’s between vCenters. VR supports various Business Continuity and Disaster Recovery scenarios and can also be used as a backup solution as replications can use the same vCenter for both source and destination. 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
