Data and database Obtain detailed information about data storage, the OSS file
system and the current database, including the characteristics of
SQL/MP or SQL/MX tables or Enscribe files. Use this information
to identify any changes that might be required to migrate data
and the database to the new system.
Data center Examine the capabilities of the current data center environment,
including AC power distribution, uninterruptible power supply
(UPS) systems, HVAC systems, and equipment space and floor
load capabilities. Identify data center changes needed to
properly support the demands of the Integrity NonStop NS-series
system.
Hardware Define the hardware infrastructure for the Integrity NonStop
NS-series system based on current and future system
requirements. For example, determine whether existing NonStop
S-series system hardware, including disk storage and tape
storage devices, can or cannot be successfully migrated and
which new hardware is required for the Integrity NonStop
NS-series system.
IT operations Although IT operations for the Integrity NonStop NS-series
system are usually much like they are for the NonStop S-series
system, it is important to identify all significant differences. These
differences might include replacing Total System Management
(TSM) with HP NonStop Open System Management (OSM),
identifying new Event Management Service (EMS) messages,
replacing the tape boot with the system image disk, and updating
the computer system operations run book.
Management practices Business and IT managers must determine whether migration to
the new system platform makes sense. To make this
determination, they need to accurately consider factors like
return on investment (ROI) calculations, opportunities for serving
new customer markets, and program costs for training,
applications development, project management, and new
hardware and software acquisition.
Networking and
communications
If the current system uses networked NonStop systems, identify
the types of connections used (for example, EXPAND, FOX,
ServerNet SAN, and so on). Also identify the WAN and LAN
capabilities, protocols, and communications software required by
the applications. Identify any potential bandwidth or performance
issues and their impact on applications.
Most networking and data communications protocols and
devices for the NonStop S-series system can be used on the
Integrity NonStop NS-series system. Identify those that cannot
be used and must be replaced.
