HiTest Notes for Lotus Domino Windows NT Prioris MX
2–9
Characterization tests performed for Mail, Mail and Shared Database, and Groupware B users
showed high performance compared to competitive systems. These tests show similar
performance to that documented in the “Prioris ZX 6200MP Lotus Notes R4.11A for NT
(3.51) NotesBench Report” that is available from the NotesBench Consortium, at
http://www.notesbench.org/. The more recent results have not yet been published.
The report shows that as many as 2100 Mail-only users may be supported on a suitably
configured dual CPU Prioris server.
The report includes the information required to compute everyday workload capability based
on a realistic mix of work. A typical business mix is 60% Mail only, 30% Mail and Shared
Database (Mail DB), and 10% Groupware B. Using this mix, and allowing for uneven
workloads, a maximally configured HiTest system will support approximately 300 total users
in a RAID 5 disk configuration. Should you choose not to use the data availability features,
the same configuration will support approximately 450 total users in a RAID 0 disk
configuration.
A larger user base may be supported in non-HiTest configurations by adding memory and
disk space to the dual CPU Prioris. DIGITAL recommends that the HiTest Suites using the
AlphaServer 1200 or AlphaServer 4100 be considered in such situations.
Figure 2-4 shows the workload capability.

Services
DIGITAL offers a range of service options. The following portfolio of Business Critical
Services is available for HiTest Suites and is backed by the DIGITAL Uptime Guarantee.
Proof of Commitment: The DIGITAL Uptime Guarantee
The DIGITAL Uptime Guarantee is a formal contract that commits DIGITAL to keeping a
client’s business critical systems in operation at least 99.5% of the time, excluding outages
beyond the control of DIGITAL, such as electrical shutdowns, environmental failures, and
downtime caused by application failure. If uptime levels are lower than 99.5%, clients do not
pay the full service charge.
Portfolio of Business Critical Services
The three vital elements of DIGITAL Business Critical Services are:
• Availability Review
The first step in initiating a Business Critical engagement with DIGITAL is a
customized, in-depth availability analysis of the computing environment, beginning with
an overview of operating goals. This review identifies potential risks and trouble spots in
hardware, software, operations, physical environment, and network. A comprehensive
written report forms the basis for determining serviceability requirements.
