Yes. you can make the server itself high available using like for example a high available SAN and multiple compute nodes using this SAN as storage or you can make the web stack high available by copying the files and databases to a second server and doing Failover/Load Balancing among them.
It's all about the infrastructure. If you have 1 or 10Gbit private network between the cluster members this shouldn't be a problem. You can always reach them out and see if their solution works for you. If not then a custom solution is the way to go
