Temporary Instant Capacity is the ability to turn Instant Capacity CPUs that are already installed in the
system on and off for short periods of time to provide added capacity. Temporary Instant Capacity
gives customers the ability to adjust to unplanned or planned spikes in computing.
Cell board Instant Capacity extends the Instant Capacity value proposition to include a complete
standby cell board (CPUs and memory) in the system for a fraction of the cost. When processing
capacity is needed, simply activate the cell board (memory and at least one CPU) to immediately
increase the compute power of the server.
HP Instant Capacity tools use the following algorithm to activate new processors:
1. Verify that there is at least one active CPU per cell board
2. Activate CPUs round-robin style across cell boards within a partition—the number of active
processors per cell board will differ by, at most, one across the partition
3. Enable CPUs on a cell board in the order 0, 1, 2, 3; this spreads the CPUs across the two internal
cell controller buses and allocates CPUs in the best thermal fashion
4. When a failed CPU is replaced, choose one from the same cell board when possible; if that is not
possible, choose the next available CPU, following rules 2 and 3
For best performance, all cell boards in the same partition should contain the same number of active
processors. For high-availability reasons, each cell board should contain at least two active
processors.
Ease of management
As the number of servers grows and server farms proliferate, IT professionals have come to realize
that the cost of managing these servers can add up to many times the actual cost of hardware. In the
HP Integrity rx7620-16 and rx8620-32 Servers, HP has provided features to make management
easier and less taxing. Add HP management software that interfaces seamlessly with the Integrity
rx7620-16 and rx8620-32 Servers, and you’re assured of a lower total cost of ownership (TCO) and
higher overall efficiency.
Management Processor
Both servers have a dedicated Management Processor (MP) that simplifies and extends system
management and enhances serviceability. The MP feature set was designed to reduce or eliminate the
need for the system administrator to be physically at the system to perform tasks such as diagnostics,
system management, or even hard resets.
Partition Manager software
The Integrity rx7620-16 and rx8620-32 Servers come with HP Partition Manager (parmgr) software,
which makes specifying, setting up, and reconfiguring partitions easy and straightforward. You can
launch Partition Manager as a GUI from HP System Administration Manager (SAM) or directly from
the command line. Partition Manager running on HP-UX can manage Windows and Linux partitions.
