Workload and Performance
• Versus multiple single-function Intel Domino servers
• When reliability, manageability, and availability are a critical requirement in new or
current Domino implementations
The Dedicated Domino processors are tuned specifically for Lotus Domino workloads. They
provide sufficient capacity for non-Domino workloads, such as remote DB2 access, file
serving, Integrated Netfinity Server, and TCPIP which support a Domino environment.
• Lotus Domino workloads: Defined as out-of-the-box functions such as:
– E-mail
– Calendars and scheduling
– Web serving
– Standard Lotus Domino template applications (for example, discussion database,
workflow, and so on) and custom developed applications written with Domino
Designer that perform no external program calls, relational database access, or Java
integration.
• Non-Domino workloads: For customers planning significant use of non-Domino
workloads, the AS/400e Dedicated server for Domino should not be proposed.
AS/400e server 270 or 8xx with standard processor features should be considered.
Restrictions for non-Domino workloads are as follows:
– Any and all workloads not designated as Domino workloads are considered to be
non-Domino workloads. They should be managed to a maximum of 10 to 15% of the
CPU.
– Standalone Java, RPG, COBOL, or C applications are non-Domino workloads.
– Applications that can work alongside Domino on the same AS/400e. An example is a
Domino server that uses the *MSF SMTF Services option along with the QMSF task
to process Internet mail through the OS/400 SMTP server. The OS/400 SMTP server
and QMSF task are non-Domino work.
– Domino applications using application integration functions, such as DB2 Universal
Database access or external program calls, are considered non-Domino workloads.
• System administration: AS/400e Dedicated server for Domino can be effectively
managed when there is no Interactive CPW (Interactive CPW = 0) available for
application workloads. Interactive CPW is an approximate value reflecting the portion
of Processor CPW that can be used for workloads performing interactive-based tasks
(5250). The zero interactive CPW is intended to support a single interactive job for
system administrative functions.
– Any job started from a console (green screen) to perform system administration
function is not considered interactive work if it is the only interactive job running
(single interactive job exception).
