Virtual Partioning on hpux

[Shivkumar]

Dear Sirs;

Is partioning on HPUX superior as compared to IBM's AIX LPAR/DLPAR technology ?

Thanks,
Shiv

In my previos job, I administrated AIX and OS/390 (MVS) systems. The Origin of LPAR is OS/390 (mainframe OS). IBM adapted it to AIX. Although LPAR is more mature than VPAR, VPAR is one of the best virtual partitioning solution. In AIX, you can use only virtual partition, there is no hardware partition option. In HP-UX, you can both of them: VPAR and NPAR.

Hi Shiv,

I do not have any experience of handling similar systems in AIX but HPUx vpar and npar are widely used and are good enough to be relied upon.

Here is the official partitioning documentation for both npar and vpar.

hi shiv,

i like this server partitioning perspectives from Gartner:

Hi Shiv,

As far as i know, vPAR is the best available in the market today. Where it stands tall :

1) Stability
2) Utilization
3) Consolidation
4) Availability

HP Virtual Partitions
Key Features:
-Run multiple versions (instances) of HP-UX simultaneously on one server or nPar
- Application and OS isolation (application, name space, OS and kernel isolation)
- Separate OS instance
- Applications are fully isolated (SW)
- Dynamically create, modify or delete one OE without interrupting non-related partitions
- Single CPU granularity (recommend at least 2)
-CPU migration - Dynamic reassignment of CPUs across virtual partitions without reboot
- Support of hp 9000 rp5470, rp7400, Superdome/rp8400/rp7410 (including nPar)
-Support for PA-8800 dual core module on Superdome, rp8420 and rp7420 with 3.1
- Individual reconfiguration and reboot, e.g. for rolling upgrades (virtual partitions donâ t affect each other)
- Both GUI and command line interface
- Single toggle console (in future consolidated console)
- Compatible with PRM, HP-UX Workload Manager, and MC/ServiceGuard, iCOD
- Greater flexibility compared to nPars

[Ted Buis]

IBM lacks hard partitioning (nPars) totally. Thus they do not have anyway to electrically isolate partitions. IBM's AIX LPAR is closer to HP's Integrity Virtual Machines. HP's vPars are implemented differently from IBM's AIX LPAR and have greater isolation of hardware resources and much less overhead. Overall, if you look at the total virtualization capability, including Secure Resource Partitions, IVM, vPars, nPars, Workload Manager and Global Workload Manager from HP you will see HP's suite is more comprehensive. HP's solutions also integrate with ServiceGuard. You should check closely IBM's ability to do both HACMP and sub-CPU LPARS.
