A failover cluster also required shared very reliable storage that is independent of the clustered servers, e. I'm not sure whether you can migrate Exchange, but most applications need to be installed in clustered mode, so you can't just upgrade. You would need to install R2 Ent on 2 servers, set up the cluster, and then install Exchange on the cluster. As you can tell from the post, I have a complete setup using R2 standard and Exchange functioning very well but now have a need for high availability.
Will this NLB cluster work for what im trying to do? I do NOT have the databases mailbox and pub folders on a shared resource so I would have to move the to a SAN to build a failover cluster. This post on ExchangeServerPro hints at the fact that I can build two separate servers with local resources and put them into a NLB cluster and it will work like a failover cluster These servers in NLB would be the frontend ones, not the Exchange server in the backend role which hosts the databases. If you are looking for high availability, then you can't use NLB, you would need to install Exchange on a cluster.
I don't have direct experience with Exchange clustering, but if it's anything like SQL then you would need to:. Thanks for your help. Sunday, August 19, PM.

User posted Hi cgelo, You had mentioned that," When I create the NLB cluster everything seems to work but when I stop one node and then try to start it again it reports converging indefinitely. I suggest you to refer the links below may help you to solve the issue. Tuesday, August 21, AM. User posted Disregard, it looks like NLB is clustered. This allows you to have multiple incoming connections each serving up the same content, providing a redundant load balancing layer as well as a redundant application layer.
It can keep a track of the request load it has sent to different nodes of a particular service. A gateway could be intelligent enough to balance load between different nodes of a particular service.
The Windows Event Viewer is an administrative tool found in all versions of Windows. Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.
How do I get rid of NLB? What is Windows NLB? What is the difference between an NLB and a failover cluster? Which of the following is a constraint of using NLB clusters in Unicast mode that you will need to design for? What is NLB cluster? What is Alb? Is load balancer a network device?
Therefore, internet-facing load balancers can route requests from clients over the internet. Select the elastic network interface. Choose the Details tab. This is the primary private IP address of the elastic network interface. Whereas a request to a specific URL backed by a Classic ELB would only enable routing to a particular pool of homogeneous servers, the ALB can route based on the content of the URL, and direct to a specific subgroup of backing servers existing in a heterogeneous collection registered with the load balancer.
Multiple Load Balancers for Redundancy and Scalability This allows you to have multiple incoming connections each serving up the same content, providing a redundant load balancing layer as well as a redundant application layer.
