PowerVM Placement – TOPOLOGY VIEW

As a end user of the Capacity Planner I wanted to see some good graphical user interface which help me visualize my environment and
analyze the LPARS of placement… Sure, we are trying to improve Capacity Planner user interface. For
the power placement we have introduced ‘TOPOLOGY VIEW’
which provide the better GUI experience
‘Topology view’ for power placement, sounds interesting…. Can you tell me more about the
same….
When Capacity Planner does the LPARS placement, it suggests
optimized way to place the LPARS based on their utilization and system capacity. How does it sounds to you if we show your current environment details, Capacity planner suggested environment and LPAR movement
details in one place… don’t you want some thing like that?

Hmmm…. It all sounds interesting.. But I don’t believe it unless I see it
myself…Let me explain more about the
‘Topology view’ we have introduced for Power Placement.
Let us say, using the Capacity Planner you run the placement
algorithm and it does the suggestion of LPAR sizing and optimized
placement
Ok… now how does ‘topology view’ visually represents optimized
environment suggestion?
‘Topology View’ shows your Physical Server, with in which you see two groupings.
‘CURRENT Topology’ and ‘SUGGESTED Topology’. Current topology will have all the
LPAR details of your current environment. As you will guess ‘SUGGESTED topology’ shows
all the LPARs Capacity planner suggested after optimization and applying the rules.. I
hope you know that you have apply your own rules during optimization.. Take a look at
Topology view for placement..

I see lot of boxes… Can you explain more what do they
represent? If my environment has hundreds of LPARS will Topology view handle it? How can I see all
those LPARS.. Wouldn’t they become very small to see what they
are
Let me explain more about what you are calling ‘boxes’.. Each box
represents a LPAR. Topology view has zoom in and zoom out facility… so if you have hundreds of LPARS you can still see all of them and you
can further zoom in to view more closely
Hmmm… what are those big grey boxes.. What are those yellow,
green and red boxes?
Let me explain to you what each colored ‘boxes’ represents.. I will also
show by zooming in further

Ah ha… so now I am seeing some usefulness of Topology view.. So Grey boxes represents Physical
Servers and with in which Existing/Suggested Topology. With
in which it furthers groups as LPARS and VIOS. With in each
LPARS group, its further groups as Dedicated, Default Pool and User
Defined pool LPARS.
You are right! Doesn’t it grouping helps you visualize your
environment better?
I assume you represent Existing LPAR with yellow background and
Suggested LPAR with green background
Right!! Did you also observe if during the analysis, if
some LPARS are not able to be placed, especially
when colocation/anti colocation rules are applied, those not placed LPARS are grouped separately on top
near HMC. They are represented with red
background
So Fictitious LPARS are represented with ‘?’ mark to differentiate
That is correct. User creates the Fictitious LPAR to do ‘WHAT-IF’ analysis and its represented with ‘?’ mark.
LPARS without ‘?’ are discovered one which are loaded via ‘load configuration’.

Now I can see Physical servers and LPARS. Is there a way I can see
details about them?
Yes. Just double click on the item whose details you want to see Or you can also right-click and select ‘properties’ menu. It will show you properties dialog
So if I double click on Physical Server, it will show the details of the physical server and if I do the same on LPARs it shows the details of the
LPAR
Correct!!.. For physical server it shows model
details, activated cores, memory available etc. For
LPARS it shows Entitlement, Memory
assigned, OS details etc. For LPARS it also shows
the utilization details
If you just the bring mouse over each of the node, it shows ‘mini’ details….

‘Mouse over’ will show the details about the item
I see lot of colored arrows in each LPAR. Do they represent some
thing?
Oh yes.. Each colored arrow has specific meaning. Just by
looking at it you can visualize what happed to LPAR during the
placement
At the bottom of the view you see list of arrow which
represents the ‘status’ of the LPAR. Black background for Discovered LPAR and grey
background for Fictitious LPAR

Blue Arrow – LPAR PLACED on same Server
Green Arrow – LPAR PLACED on different Server
red Arrow – LPAR NOT PLACED
yellow Arrow – VIOS created during placement

Is there a search facility? If I have too many LPAR and I want to look for specific LPAR, is it possible?
I understand your concern. If there are hundreds of LPAR
how to locate a specific LPAR. You can achieve it by using the
search facility
You can click on ‘Search’ button on top, that will open search
dialog. You can search based on the Physical server name or
LPAR name
If I want to see only LPARS that are moved to different server.. Is it
possible
Yes. That is also possible to selecting the status icon at the
bottom
Start typing the item you want to search, filtering of data happens
Centers the selected item in the topology view
Highlights the selected item in the view by blurring rest of the
items
Clears the search and highlights all the items back to original
position
HA2 item selected is highlighted.Click Search->’Clear Search’ to
clear the search
Click on ‘Current Discovered’ icon. All the ‘Current Discovered’
nodes get highlighted
You can also select multiple icon. Its highlights all of the
selected ones. You can also see the Filtered item count
If I have so many LPARs and many physical servers. If during the
placement if the LPAR is moved to different server is there a way I can see which server it went to? Or if
there is a LPAR in Suggested topology can I see from which server that LPAR came from
Yes… you can do that also!! All you have to do is right click on
the node. You will see the context menu. Select which ever
you want.

I feel these LPAR movement representation help me analyze the placement suggested by Capacity
planner… I feel this is very powerful capability
You can also see all the movement once. Also note that you have save the topology as image or you can printout the
same.
DO ‘YOU’ ALSO FEEL TOPOLOGY VIEW REPRESENTATION ENHANCE THE USER VISUALIZATION EXPERIENCE FOR PLACEMENT?
PLEASE DO LET US KNOW………
