chris HCX OS Assisted Migration (OSAM for short) is a VMware tool where VMs hosted on either KVM or Hyper-V or can be migrated into vSphere.

If you have a relatively small HCX deployment, for example a legacy vCenter environment connected to a single VMC on AWS SDDC, lifecycle management of the various HCX components is quite straight forward; you could simply log into each manager (2 in this case) and have a look in the UI, or check the VC … Read more
VMware Cloud Disaster Recovery (VCDR) is a relatively new product, certainly compared to Site Recovery Manager (SRM) which has been around since 2007; to put that into perspective, vSphere 5.0 didn’t go GA until 2011. The basic premise of the products are similar in that we configure protected sites, recovery sites, as well as folder … Read more
I decided to upgrade my home lab vCenter to version 8, and I faced an error on stage two of the deployment: Helpfully, the log download failed! If I logged into the new appliance as root I could see that /storage/seat was full. Odd. After a bit of searching I found some old posts on … Read more
