3.2.4 Configuration Example - Pattern Overview
Examples of Determining Partition Configurations
Focusing on Reducing the Downtime at a Failure (A, B, or C)
•
For a cluster configuration, a few seconds to a few minutes (a guideline for a two-node configuration)
•
When the Reserved SB function is used, switching time + OS startup time (approximately 10 minutes or longer)
Focusing on Extensibility
•
Focusing on performance: Multiple CPUs (up to 8 CPUs), 192 cores (D)
•
Focusing on functions: The maximum number of connectable PCI-Express cards internally is 16, and 56 with PCI
expansion boxes. (E)
Server Integration
•
Physical Partitioning (PPAR): Reserved SB switching can also be used. (F)
•
Extended Partitioning (Ext.Par.): Division unit consists of one CPU core, 1GB of memory, and one I/O PCI card. (G)
