System Requirements
Use the requirements below to assess whether your resources and third-party systems meet the requirements to deploy a high availability environment.
| Hardware | Normal HA operations require two servers. Virtual machines can be used as long as enough resources are allocated to them. |
| Operating Systems |
ACM only supports Linux platforms.
Note: Red Hat high-availability packages (such as ricci, luci,
rgmanager, and cman) are not used, and therefore must not
be installed or activated in the environment. The system clocks of all hosts in the HA environment must always be kept in sync in order for ACM to operate correctly. IBM Aspera typically recommends using the ntpd daemon, but any time-synchronization mechanism should work fine. |
| Software |
IBM Aspera Shares version 1.9.12 and higher. IBM Aspera High Speed Transfer Server 3.8.0 and higher. IBM Aspera Cluster Manager: ACM Package |
| Shared Storage |
Shared storage is used for:
Important: The shared storage must be 100% reliable and accessible 100% of the time for ACM to secure highly available Shares operation and to prevent Shares data corruption. IBM Aspera recommends dedicating storage for ACM whenever possible, in order not to create I/O bottlenecks when large packages are being transferred to shared storage at very high speeds. ACM has been tested successfully on these shared file systems:
|
| Load Balancer/VIP |
A load balancer that implements a VIP (Virtual IP) is required. For more information about what is expected from the load balancer, see Expected Load Balancer Behavior. |
Single point of failure
Aspera strongly encourages customers to consider SPOF (single point(s) of failure) in the environment and to recognize the risks of SPOF. Often, these are situations where all nodes are plugged into the same power strip or surge. It could also be that the shared storage or the load balancer are not HA.
