Hi All,
We have four servers where we can't retrieve our free ESXi VMWare
license after Broadcom shut things down and they are in evaluation
mode for about 30 more days.
Similar products are Microsoft Hyper-V, Oracle Linux Virtualization
Manager (OLVM), Proxmox and Nutanix. Each one of these products has
some shortcommings compared to VMware. If you don't need a GUI to
manage your virtual environment you might consider using KVM (Linux)
or bhyve (FreeBSD) as hypervisor.
What sort of shortcomings do you see for, say, Proxmox? I would say
that by using Open vSwitch & Free Range Routing (with EVPN), one can
get pretty close to the VMware NSX. And with enabling Ceph on Proxmox,
one can get the VSan-like functional distributed/block storage. Then
throw Ansible at it for automation. And Prometheus/Grafana for
monitoring/observability.
Proxmox does not support the current architecture I have at work:
clusters of hosts served by a central storage system connected to the
hosts by FC SAN. I run few huge volumes on the storage that are shared
among the cluster hosts. As I have seen this architecture in many
companies I think I can the lack of support for it a shortcoming.
It might be an old fashioned architecture, but it served me well for
many years. I know I could work around that by presenting individual
volumes to each host and then put Ceph on it to get something like vSAN.
But that would be a) a ton of work and b) a mixture of architecture that
increases complexity.
Unfortunately we just bought new hosts and a storage system tailored to
that architecture just a few weeks before the mess with VMware became
public. So I'm stuck with the architecture for the next couple of years.
At work we are currently building a PoC with OLVM as we have Oracle
licenses anyway. And because OVLM is the one product that comes
closest to the feature set of VMware we need. But I still hope we find
a way forward with VMware. Moving everything to Oracle gives me
nightmares.
