Challenges - Economically

4

� How utilized is my current investment ??

� How many additional customers / systems can I move

to the existing Hardware ??

� When will be the time for the next investment ??

� Which investment will deliver the best price /

performance ratio ??

Challenges - Technically

5

� Monitoring of all potential bottlenecks

� Notification in the case of exceeding defined limits

� Monitoring of the virtualization layer

� Automated creation of Performance Graphs for

Management as well as Customers

� Documentation of the Virtualization Layer

Monitoring (Performance)

6

� Top-Down Approach

� Layer 1 (Impact to all client LPARs):

� Power Server utilization (e.g. LPAR2RRD)

� Storage Utilization

� Layer 2 (Impact to “some” Client LPARs):

� VIOs Performance Utilization (FC, SEA)

� FC Switch Port

� Power Server Bus Utilization

� Layer 3 (Impact to one Client LPAR):

� Client LPAR Utilization

Storage Utilization


� Overview about the Storage Utilization:

� Frontend IO/S und MB/s

� Backend IO/S und MB/s

� Virtual Disk IO/S und MB/s

� Physical Disk IO/S und MB/s

� CPU

� Cache Usage

VIOs Utilization – Fiber Channel


� Important is to recognize immediately which Client LPAR

is causing which part of the work load

Individual LPAR !!

VIOs Utilization –

Shared Ethernet Adapter


� Important is to recognize

immediately which Client

LPAR is causing which

part of the work load

Individual connections!!

IOA Utilization – Client View


� Shows the total FC Work Load produced by one client LPAR

FC Switch Port


� Because of a Zoning n-Host Ports to 1 Storage Port

there might be a performance issue

� Shortages at Metro

Mirror connections

have an immediate

impact to all mirrored

Client LPARs !!

Power Server Bus Utilization


� Dependent on the used HW it is possible to monitor the

utilization of the System Bus (connection between

system unit and expansion drawers)

� It is important to avoid in balances of the System Bus

© 2013 IT-PS

Client LPAR Utilization


� Analysis and graphical

presentation of all

Performance

information is possible

� Requirements are highly dependent to the usage of each

system and might differ a lot between customers !!

Monitoring (Availability)

16

� Monitoring the Availability of all Components

� Producing a list of all Errors of the following components:

� HMC all Serviceable Events

� VIO Server all Error Log Entries

� FC Switch e.g. CRC, ENC, Trunk Error, BBC 0, …

� Notification in the case of Events via E-Mail

� Customizable based on the Severity

� If required notification via SMS
