This technote explains why it is desirable to run Domino on System z.
Why run Lotus Domino on System z?
An IBM System z server can support large workloads, because IBM has invested in many capabilities in the processor and software to provide scalability.
System z offers the following key points that you should be aware of:
– Very efficient use of symmetric multiprocessors (SMPs), even up to 16-engine machines
– Addressing of terabytes of expanded processor memory and System z support of 64 GB of central memory
– Efficient techniques for keeping data in processor memory where it can be accessed quickly
– A sophisticated job scheduler
– The removal of bottlenecks
– Shared access to all disks by all processors
– Separate, dedicated I/O processors
– Efficient automated procedures for backing up terabytes of data
– XPLink exploitation, providing between 25 and 30 percent CPU reduction for Domino 6 for z/OS over Domino R5 for S/390
- Domino can also be run on Linux to gain the benefits of System z hardware and I/O
