|
| Why twice the nodes? The manager is optional -- but do you need
| multiples?
|
| Also, when I looked into clusters (that I haven't implemented,)
| I did see qdevices. It's a way to have a cheap and weak third
| node just to break ties.

|
| You can set up a cluster to play with multiple nodes without
| the just-announced PDM 1.0. Or you can use PDM to manage three
| stand alone nodes.
|
| If you want to do both, perhaps a 3-node cluster plus a 1-node
| stand alone with a PDM 'overlay'. So just a +1 versus a 2x.

| You can migrate a three node cluster from VMware to PVE using

|
| iSCSI SANs don't (yet) do snapshots on PVE. I did take a three
| node Dell + flash SAN and an additional temporary box with
| rather a lot of RAM and disc (ZFS) and took the SSDs out of the
| SAN and whistled up a Ceph cluster on the hosts.
|
| Another customer, I simply migrated their elderly VMware based
| cluster (a bit of a mess with an Equallogic) to a smart new set
| of HPEs with flash on board - Ceph cluster. That was about two
| years ago. I patched it today, as it turns out. Zero downtime.
|
| PVE's high availability will auto evacuate a box when you put
| it into maintenance mode, so you get something akin to VMware's
| DRS out of the box, for free.
|
| PDM is rather handy for the likes of me that have loads of
| disparate systems down the end of VPNs. You do have to take
| security rather seriously and it has things like MFA built in
| out of the box, as does PVE itself.
|
| PVE and PDM support ACME too and have done for years. VMware
| ... doesn't.
|
| I could go on somewhat about what I think of "Enterprise" with
| a capital E software. I won't but I was a VMware fanboi for
| over 20 years. I put up with it now. I also look after quite a
| bit of Hyper-V (I was clearly a very bad boy in a former life).
