Configuring High Availability

Maybe you start here.
You do need shared storage for VMs and containers.
On another note, you mention "both" nodes. Be aware that to use a HA Proxmox cluster - you need at least three cluster nodes (to get reliable quorum) or any odd number higher than this. You could possibly use a QDevice for this, see here.
You should also carefully consider your various networking requirements - for a decent HA enabled cluster.
I'm not sure if anybody is going to do the whole setup for you - but you'll always find a helping hand from this awesome forum.
In general they don't need to be, however if any VM relies on something HW specific on a node, then obviously this must also be replicable on the other node. There are quite numerous examples of such things.

> The quorum server will manage replication on the 2 servers, correct?
Actually no, the qdevice only acts as a "witness" and typically has very minimal functionality. I run mine as an LXC container with 128MB RAM on a standalone node.

No - a QDevice (correct term) will maintain the balance of the voting system for the Quorum.
Proxmox VE use a quorum-based technique to provide a consistent state among all cluster nodes. A quorum is the minimum number of votes that a distributed transaction has to obtain in order to be allowed to perform an operation in a distributed system [0].
I've glanced at your recent posts, and I feel I must tell you that you are going to have to read up, on all PVE documentation (& Linux in general) before attempting to build up your required cluster.
I would suggest starting with a single node - and start learning / experiencing from there.
Linux & PVE specifically, definitely have an unavoidable learning curve - but you have to do that if you really want to build a functioning & serviceable digital ecosystem. This will take time - but well worth it in the long run.

I want to Test Proxmox HA with 2 Nodes . for my test i don;t have a 3rd Nodes.
Added Cluster 2 Nodes and HA want to test.
One Sever is HP
Another Server is Dell
RAM is fine on Both Servers
For Storge Using Shared one. keeping all VMs
Would be fine ? will i able to achieve HA with 2 Nodes? are mandatory to have 3 Nodes?
Please advise

No it won't be fine. I'll try plain English. HA requires a quorum based voting system so that the system can "decide" who is up & available & who is not. Think about it in theory & you'll soon realize; how can each node that can't find the other one know who's fault is it. With a 3 node voting system, its pretty simple the 2 that can speak to each other "decide" that the third unreachable one is the one that is unavailable. So in short you need to install a QDevice. You can put it on almost any PC or SBC or even an arm-based RPI. But without it - no working HA, I'm afraid.
Good luck.
