HP OpenVMS Version 8.3 for Alpha and Integrity Servers
HP OpenVMS Version 8.3 for Alpha and Integrity Servers SPD 82.35.11
• Accommodates those customers with unpredictable
or planned temporary processor demands
Operational features:
• Works with processors, does not include Cell boards
or memory
• Customer orders standard iCAP processors and
pays the same discounted price
• Customer then purchases one or more 30-CPU day
right to temporarily activate one or more iCAP CPUs
• Does not require an email connection from customer
site to HP
• The iCAP software issues a warning before the
TiCAP license is likely to expire, based on the rate
of depletion that it tracks across all relevant CPUs
• Hardware Services are included for the CPUs acti-
vated by the TiCAP license
• The relevant Operating Environment (OE) is auto-
matically licensed on activated TiCAP CPUs
Note: Other HP and 3rd Party software have their
own licensing policies and it is recommended that cus-
tomers purchase sufficient software licenses to meet
peak needs.
Pay Per Use (PPU)
PPU is a leasing program with HP Finance which cus-
tomers pay only for CPU computing capacity they use.
Key features:
• Runs on all OpenVMS Integrity cell-based systems
(rx7620, rx7640, rx8620, rx8640, and Superdome)
• The customer pays a fixed minimum monthly lease
and a variable monthly amount which is based on
actual usage of CPUs
• The customer is guaranteed that for any given month
the PPU charge will not exceed 105% of the standard
lease cost
• The customer is guaranteed that over the full term
of the lease - either three or four years as initially
chosen by the customer - the total PPU lease charge
will not exceed 100% of the standard full term lease
cost system
• There are two types of PPU:
• Actual percentage of utilization of each CPU, aka
Percent CPU
• A count of the number of active CPUs, aka Active
CPU
• Percent CPU and Active CPU are mutually exclusive
on any single Integrity system
• The full corporate implementation has been executed
allowing OpenVMS to share PPU CPUs with HP-UX
and Windows-64 (Percent CPU only) on a common
partitioned Integrity system
Operational features:
• A PPU Metering Agent running on a target system
continuously measures CPU resource utilization on
every installed CPU
• This utilization data is sent to a Utility Meter running
on an HP Proliant system that can support up to 99
individual PPU systems
• This system securely communicates with the HP Util-
ity Web Portal every 24 hours, sending collated uti-
lization information on each PPU system
• 48 hours later the customer may access the Utility
Portal through a secure connection and access us-
age statistics for that 24 hour period for each system
and/or hard partition
• This information enables the accurate billing of Busi-
ness Units for the actual CPU resources they have
consumed
OPERATING SYSTEM ENVIRONMENT
Processes and Scheduling
Executable images consist of system programs and
user programs that have been compiled and linked.
These images run in the context of a process on Open-
VMS systems. Sixty-four process priorities are recog-
nized on OpenVMS Alpha and OpenVMS for Integrity
servers. Priorities 0 to 15 are for time-sharing pro-
cesses and applications (four is the typical default for
timesharing processes). Priorities 16 to 63 on Alpha
and Integrity servers are for real-time processes. Real-
time processes can be assigned higher priorities to en-
sure that they receive processor time whenever they are
ready to execute.
OpenVMS uses paging and swapping to provide suf-
ficient virtual memory for concurrently executing pro-
cesses. Paging and swapping is also provided for pro-
cesses whose memory requirements exceed available
physical memory.
64-Bit Virtual Addressing
The OpenVMS Alpha and OpenVMS for Integrity
servers operating systems provide support for 64-bit vir-
tual memory addressing. This capability makes the 8 TB
virtual address space available to the OpenVMS Alpha
and OpenVMS for Integrity servers operating systems
and to application programs. Future hardware imple-
mentations for Integrity servers will provide greater ca-
pacity. OpenVMS applications can take advantage of
64-bit processing by using 64-bit data types supported
