Horizontal Scaling for High Availability Needs

Serv-U High Availability

Serv-U supports "N+1" horizontal scaling to meet your high-availability ("HA") needs. Additional Serv-U FTP Server or Serv-U MFT Server licenses can be purchased to upgrade a standalone system to an active-active webfarm for additional redundancy, throughput or session capacity.



Serv-U can be clustered
like a web farm for HA.
Serv-U Gateway can also
be clustered for HA.
Our Distributed Architecture
Guide has the details.


Increases System Capacity

  • Up to five Serv-U servers supported in a single cluster
  • Up to three Serv-U Gateways supported in a single cluster
  • Support thousands of concurrent sessions
  • Linear increase in throughput capacity

Leverages Your Infrastructure

  • No processor or core limits
  • Native 64-bit applications maximize performance
  • Supports deployment on virtualized nodes (e.g., VMware vMotion)
  • Backed by Active Directory or the shared database of your choice
  • Backed by the shared storage of your choice
  • Fronted by the network load balancer of your choice
