<strong>HP</strong> <strong><strong>nPar</strong>titions</strong> (<strong>nPar</strong>), <strong>for</strong> <strong>Integrity</strong> <strong>and</strong> <strong>HP</strong> <strong>9000</strong> <strong>cell</strong>-<br />
based servers<br />
Overview<br />
A hard partition, also referred to as an <strong>nPar</strong>tition or <strong>nPar</strong>, physically divides the computer into groups of <strong>cell</strong> boards which operate<br />
independently of other groups. Hard partitions isolate application environments from single points of failure, meaning applications<br />
running within hard partitions are not affected by hardware or software events occurring in other partitions. Each <strong>nPar</strong>tition executes<br />
a single operating system image, providing software isolation <strong>and</strong> enabling alternate <strong><strong>nPar</strong>titions</strong> to execute different versions of the<br />
operating system.<br />
Starting with <strong>HP</strong>-UX 11i v3 Update 1 (September 2007 Operating Environment Update Release [OEUR]), <strong>HP</strong> released <strong>HP</strong>-UX 11i v3<br />
Dynamic <strong><strong>nPar</strong>titions</strong>. <strong>HP</strong>-UX 11i v3 dynamic <strong><strong>nPar</strong>titions</strong> allows hard partitions (<strong><strong>nPar</strong>titions</strong>) to be changed online, while applications<br />
continue to be available to meet business objectives without interruption. For more in<strong>for</strong>mation, see:<br />
External "<strong>HP</strong>-UX 11i v3 Dynamic <strong><strong>nPar</strong>titions</strong>, Features <strong>and</strong> Configuration Recommendations" white paper at<br />

Three videos about <strong>HP</strong>-UX 11i v3 Dynamic <strong>nPar</strong>tition: http://hp.feedroom.com/?rf=bm, "<strong>HP</strong>-UX 11i".<br />
Features<br />
Closely corresponds to a st<strong>and</strong> alone system<br />
Enables multiple <strong>HP</strong> UX Operating Systems <strong>and</strong> applications to be run on the same physical system<br />
Provides <strong>for</strong> electrical isolation <strong>and</strong> isolates hardware failures to the specific hardware partition (<strong>nPar</strong>tition)<br />
Each <strong>nPar</strong>tition has independent processor, memory, <strong>and</strong> I/O resources allocated<br />
Resources can be moved using comm<strong>and</strong>s via parmgr without manipulating hardware<br />
Can increase/decrease processing power by adding/deleting <strong>cell</strong>s to an <strong>nPar</strong>tition<br />
Dynamic <strong><strong>nPar</strong>titions</strong> allows configuration changes in an <strong>nPar</strong>tition without requiring a reboot (starting with <strong>HP</strong>-UX 11i v3<br />
Update 1 with specific firmware)<br />
Configuration<br />
Supported on Superdome, rp8420, rp7420, rx8620, <strong>and</strong> rx7620 servers today<br />
<strong><strong>nPar</strong>titions</strong> can be granularized down to one <strong>cell</strong><br />
Maximum number of <strong><strong>nPar</strong>titions</strong> varies per server<br />
Configuration changes may require a system reboot, depending upon configuration<br />
Majority of hardware upgrades affect only a specific <strong>nPar</strong>tition. However, when running the dynamic <strong><strong>nPar</strong>titions</strong> feature<br />
available starting in <strong>HP</strong>-UX 11i v3 Update 1 (with specific firmware), affected <strong><strong>nPar</strong>titions</strong> will continue to process workloads.<br />
(Otherwise, the affected <strong>nPar</strong>tition may need to be brought down.)<br />
NOTE: Within a particular <strong>nPar</strong>tition, no 2 of the following 3 technologies can be run at the same time:<br />
Dynamic <strong><strong>nPar</strong>titions</strong><br />
<strong>HP</strong>-UX Virtual Partitions<br />
<strong>Integrity</strong> Virtual Machines<br />
Recommend using Partition Manager, a system management tool <strong>for</strong> configuring <strong>and</strong> managing hard partitions<br />
Support<br />
Support of <strong><strong>nPar</strong>titions</strong> is included in the hardware support price of the associated server.<br />

<strong>HP</strong> <strong><strong>nPar</strong>titions</strong> (<strong>nPar</strong>), <strong>for</strong> <strong>Integrity</strong> <strong>and</strong> <strong>HP</strong> <strong>9000</strong> <strong>cell</strong>-<br />
based servers<br />
Overview<br />
Requirements<br />
Only <strong>cell</strong> based <strong>HP</strong> <strong>9000</strong> <strong>and</strong> <strong>HP</strong> <strong>Integrity</strong> servers have <strong><strong>nPar</strong>titions</strong>. Today that includes:<br />
<strong>HP</strong> <strong>Integrity</strong> servers (based on the sx1000 <strong>and</strong> sx2000 chipsets): <strong>HP</strong> <strong>Integrity</strong> Superdome, <strong>HP</strong> Superdome with sx2000,<br />
<strong>HP</strong> rx8640, <strong>HP</strong> rx8620, <strong>HP</strong> rx7640, <strong>HP</strong> rx7620<br />
<strong>HP</strong> <strong>9000</strong> servers (based on the sx1000 <strong>and</strong> sx2000 chipsets): <strong>HP</strong> <strong>9000</strong> Superdome, <strong>HP</strong> <strong>9000</strong> Superdome with sx2000,<br />
<strong>HP</strong> rp8440, <strong>HP</strong> rp8420, <strong>HP</strong> rp8400, <strong>HP</strong> rp7440, <strong>HP</strong> rp7420, <strong>HP</strong> rp7410, <strong>HP</strong> rp7405<br />
Recommend using Partition Manager, a system management software tool <strong>for</strong> configuring <strong>and</strong> managing hard<br />
partitions<br />
Dynamic <strong><strong>nPar</strong>titions</strong> requires <strong>HP</strong>-UX 11i v3 Update 1 or later <strong>and</strong> specific firmware. (For firmware versions, see:<br />
