TruCluster Server High Availability Case Study
Hardware Configuration: V1.6 Archive
|
|
This high-availability cluster configuration includes the
following hardware components:
- Independently powered system cabinet with two identically configured member systems, local storage shelves, and redundant Memory Channel hubs
- Independently powered storage cabinet, which includes dual-redundant RAID controllers, an UltraSCSI hub, and shared storage shelves
- Shared tape devices
- Redundant uninterruptible power supplies (UPSs)
The following tables describe these components in more detail.
The images highlight particular details of the cluster configuration. (Images are displayed in a separate window.)
