The Full Rack version of Oracle SuperCluster T5-8 contains two SPARC T5-8 servers, each with four processor modules. The Half Rack version of Oracle SuperCluster T5-8 also contains two SPARC T5-8 servers, but each with two processor modules.
Redundancy in the SPARC T5-8 servers is achieved two ways:
Through connections between the servers (described in Understanding the SPARC T5-8 Server Physical Connections)
Through components within the SPARC T5-8 servers:
Fan modules – Each SPARC T5-8 server contains 10 fan modules. The SPARC T5-8 server will continue to operate at full capacity if one of the fan modules fails.
Disk drives – Each SPARC T5-8 server contains eight hard drives. Oracle SuperCluster T5-8 software provides redundancy between the eight disk drives.
Processor modules – Oracle SuperCluster T5-8 contains two SPARC T5-8 servers.
For the Full Rack version of Oracle SuperCluster T5-8, each SPARC T5-8 server contains four processor modules. There are two sockets or PCIe root complex pairs on each processor module, where 16 cores are associated with each socket, for a total of eight sockets or PCIe root complex pairs (128 cores) for each SPARC T5-8 server.
For the Half Rack version of Oracle SuperCluster T5-8, each SPARC T5-8 server contains two processor modules. There are two sockets or PCIe root complex pairs on each processor module, where 16 cores associated with each socket, for a total of four sockets or PCIe root complex pairs (64 cores) for each SPARC T5-8 server.
