Hyperv single server to failover

Hi
Can anyone advise me on the following.
I look after a company who have a single windows Hyperv server with a number of raid 5 disks in the local server running 3 VM servers,
This has worked great for the last 3 years but the company is expanding and want to look at a failover solution so they can limit downtime due to hardware failure.
Am I right in thinking if I put a second Hyperv server in for failover then both servers have to connect to some sort of storage and not use their own local storage

any advice would be great

Thanks

Hi @RobAndrews-5533,

Yes that is correct, if you have a failover cluster then you will need to use shared storage, this could be a storage system which may of course be expensive depending on your needs.

Here's a few excellent articles which explains Hyper-V storage in more detail:

Hey,

As mentioned, you will need shared storage to create a Failover Cluster. You can utilize existing storage in the server and use a Software-Defined Storage to create shared storage pool. S2D can be considered, but you will need to have drives connected through HBA. As an alternative, StarWind VSAN can utilize existing RAID and replicate data between Hyper-V nodes. The following guide will walk you through the configuration process:
