History
This page is a partial rewrite of the following pages to better help understand what hosts are running and where they are running.
December 2019 Central Computing Outage (Fermi)
Server and applications migration from glastlnx to fermilnx boxes
Notes on VMWare Cluster
The VMWare cluster, noted as fermi-vmclust, consists of 4 hypervisors. Two of the machines are on HA, and two are not. A VM may migrate between these two hypervisors on demand- the machines have 128GB of memory and two hypervisors are enough to run all the VMs without oversubscription of memory.
The VMWare is cluster managed by OCIO Platforms team, and they can migrate VMs on demand.
fermi-vmclust01 and fermi-vmclust02 are not HA.
fermi-vmclust03 and fermivmclust04 are HA.
Note: OCIO should be contacted about setting up occasional VM snapshots, so that a VM may always be brought up even if a hypervisor dies.
