Partitioning on 7410

[Lacrosse]

Can you create 3 seperate environments on a 7410. I realize you can only create 2 hardware partitions (nPars)
and 8 virtual partitions (vPars) can you divide up the hardware with vPars, we want 3 seperate environments on the 7410 i.e. 3 seperate LAN cards, one in each vPar, how does the OS configure into this?? one version loaded on the internal drives and seperate databases in each vPar??? it is HPUX 11i that is creating the vPar correct?? any good white papers on this...whew a lot of questions - Thanks

Hello,

Take a look at this:

http://www.docs.hp.com/hpux/onlinedocs/B2355-90762/B2355-90762.html

This should have the info you need.

Hope this helps

Hi,

vPars (virtual parititions) provides the following benefits:
-----------------------------------------------------------
Increased system utilization by partitioning previously unused portions of
the server.
Typically, a server is only using 50%-70% of its capacity.

Greater flexibility of resources through: 1) multiple but independent
operating environments
per server (with as low as 1 CPU granularity per partition) and 2) the
dynamic movement of CPU
power between vPars depending on workload requirements.

Increased isolation of applications, their operating systems, and assigned
resources (CPU, memory,
and I/O), with individual reconfiguration and rebooting of the individual
partitions without
affecting other partitions and their applications.

Server consolidation by running multiple workloads with their unique
Operating System configuration
needs on the same server at the same time. They are excellent for
dynamically creating test platforms
without investing in more hardware.

nPartitions (hard partitions) provide the following benefits:
------------------------------------------------------------
Improved system utilization through the ability to run multiple applications
and/or
different operating system images (including multiple OS versions) in
multiple nPartitions
within a single system. This enables the best use of computing resources
while providing
software fault and security isolation.

Increased uptime by providing for complete electrical and software
isolation. This ensures
that applications continue to run when a different partition experiences
hardware, software
or maintenance downtime.

Server consolidation by providing greater availability. Key to many
consolidation efforts
is the availability of the applications. By providing for electrical and
software isolation,
nPartitions enables these applications to be combined onto a single system.

You can have 7 vpar in 7410 at a time.
Once you creted a vpartion (using vparcreate) a copy of the base OS (vpar 1) will be made.
Now this is vpar2. in this vpar you can load any application/database which will be different from vpar1.
Only 11i supports vpar

Hi,

you can find the white papers here

And a great book is http://www.hp.com/hpbooks/prentice/ptr_0130352128.html

And yes, you have a few choices:

(1) just create three virtual partitions

(2) Create two physical partitions, then within one of them create two virtual partitions

Each hardware or virtual partition requires that each partition have it's OWN LAN card(s), IO (scsi/fibre) card(s), at least one dedicated CPU, and Memory assignment (the easiest way is just to assign memory based upon how much a partition needs).

Each virtual partition will have it's own boot disk, therefore each partition needs it's own dedicated IO card. IO cards can not be shared between partitions. Each partition is it's own server.
