Re: Why do companies partition their Power Servers?

Thanks for the reply, DrFranken. It's good to know that an LPAR scripting
option is available. Our Web Portal offers the option of authenticating
against IBM i system profiles. But we don't require it. And there is not
much reason for it either because we are not offering IBM i Access,
Navigator, ODBC / JDBC client interfaces. Nor are we supporting TCP/IP
clients other than browsers.

Lately I've been inundated by email from IBM, which is promoting their
Bluemix service for configuring web development and deployment environments
under Linux, using Code Foundry and Softlayer data centers. I reviewed some
of the videos and documentation. The overall message touts the simplicity
of setting up virtual machine instances and other services, which is
comparable to marketing of Amazon Web Services, Google Application Engine,
Microsoft Azure, Sales Force application services, and others.

You're obviously an innovator when it comes to Power Cloud services, and I
appreciate that.

You clearly understand the requirements of building subsystems for your
customers. This is good and it IS a valid method of supporting multiple
customers. As you state they use a 'non traditional (for i) interface'
which makes separating them with subsystems simpler than it would if they
used command lines and such. It's also likely that they don't use
traditional IBM i user profiles either I suspect which is another reason
LPARs can be better in some situations.

To build LPARs with scripting is a tad more difficult than building
subsystems that much is true. The commands in IBM i for subsystems are all
well defined and understood (OK By good admins at least!) so that is a win
for your method.

Effectively to build LPARs with a script you need connectivity to the HMC
with SSH to issue the appropriate commands there to create the partition
and it's profile. You also need connectivity to the storage (be that IBM i,
VIOS, or SAN) to issue the appropriate commands to create the new
partition, hopefully a clone by the way rather than empty disks!

Clearly this is more difficult for an IBM i specialist because the
commands on the HMC are, um, "Less clear" and involve somewhat more
parameters than CRTSBS, CRTCLS, ADDRTGE et al. But once it's all understood
it falls to SMOP once again.
