SAP Software Requirements

• LVM is an add-on for SAP NetWeaver 7.3 So you will need SAP NW AS Java of usage type “BASIC”

• Recommended Support Stacks SAP NetWeaver Release 7.30 Support Package 08 SAP NetWeaver Release 7.31 Support Package 04 For lower support package stacks, ensure that all necessary

patches are installed as described in SAP Note 1703029

We had to Install SPS 09 due to initial freezing of LVM screen

10

SAP Software Requirements (cont.)

• Obtain the LVM SCA files for deployment from SAP Service Marketplace Software Downloads Installations and Upgrades Browse

our Download Catalog SAP NetWeaver and complementary products SAP NW LANDSC VIRT MGT STDSAP NW LANDSC VIRT MGT STD 2.0 Installation

• Two SCA files needed VCM – file contains all functional coding and is the main

component of LVM VCMCR4E – file contains Crystal Reports for Eclipse and is

used by LVM to generate and display reports VCM_ENT – file that contains all functional code for enterprise

version (optional, additional licensing)

Infrastructure Required to Set Up and Test SAP LVM Requirement Details

Microsoft Active Directory Domain server – Domain controller

A Separate domain is needed to be setup for LVM validation, all the server including LVM andSAP servers will be launched in this domain

DNS Server All the servers in the domain can be resolved via the DNS

Domain usersDomain users will need to be setup for performing administration and LVM-related task in theenvironment. This domain user will have full admin access on the LVM-related servers launchedon this domain.

vSphere 5.1 This is required for demonstrating VM-based cloning, copy and refresh capabilities of LVM

vCenter /vCD server access The IP address or hostname of the vCenter server and also admin domain user who canperform specific task outlined in slide 5 below is required

VM Server for LVM One Windows VM server for Installing and setting up LVM

VM Server for SAP ERP Required for testing ABAP side of cloning and refresh

VM Server for SAP Portal Required for testing JAVA side of cloning and refresh

VM Server for SAP Solution Mgr Required for testing central monitoring capabilities

400GB additional storage space This space is required for cloned VM’s and templates

Separate network with 4 or 5 static IP address

LVM currently supports static allocation of ip address during cloning and refresh of VM’s.Dynamic allocation will also be tested during this validation.

15

Authorizations Required

• The following authorization is required for vCenter server user: Datastore Allocate Space

Global Cancel Task

Resource Assign virtual machine to resource pool Migrate Query vMotion Relocate

The technical user which is given in the Virtualization Manager configuration has to be assigned a role with these privileges if it should be fully functional

16

Authorizations Required (cont.)

• The following authorization is required for vCenter server user: Virtual machine – Interaction

Power Off Power On Suspend

Virtual machine – Inventory Create from existing

Virtual machine – Provisioning Clone virtual machine Customize Deploy template Modify customization specification Read customization specification

The technical user which is given in the Virtualization Manager configuration has to be assigned a role with these privileges if it should be fully functional

Case Study VMware Environment

• You will need to work with your VMware Administrator to get your storage, domains, and templates set up

• Our POC VMware Environment consisted of: VMware vSphere 5.x (vCenter 5.0 Standard Edition, ESXi 4.1u1) VMware vCloud Director 1.5 Instance VMware vCenter Chargeback (Read-Only) VMware vCloud Manager (vCD) Two Active Directory (DNS/Global Catalog) Servers

• Isolated sandbox environment, had a unique Microsoft Active Directory Domain

24

25

Adding VMware Templates

• Download and install the vSphere Client VMware vCloud Director should be the primary method of

management and deployment of new VMs where possible Deployed Templates here

• Access the LVM tool to assign templates to the managed pool http://<Hostname>:500<Instance #>/lvm

26

Adding Templates to the LVM Managed Pool

27

Adding Templates to the LVM Managed Pool (cont.)

28

30

Use Cases

• Visualization and Monitoring Dashboards are predefined and provides status overview of services

and resources Drilldown of logs for detailed analysis Validation of instance and server configuration details File and Agent checks

• Starting/Stopping SAP Systems Use the task planning function to automatically schedule a stop and

re-start of single instances Scheduling of mass operations is supported Customer-defined operations (hooks) can be triggered before or after

a stop/re-start operation Park systems and start them up on a free resource on demand

31

Use Cases (cont.)

• Copy/Post copy automation for SAP NetWeaver AS Java Supports SAP NetWeaver AS Java 7.00 > SP20, 7.01 > SP4, 7.02

SP4, 7.30 SAP Note: 1616352

• Automated Capacity Management Mapping conditions to flex resources up are down

automatically Some third-party software libraries were not yet available this

early in the product rollout Excluded from initial testing, based on software library

availability

7 Key Points to Take Home

• Planning – All use cases you will test, what is the goal “By failing to prepare, you are preparing to fail”

– Benjamin Franklin• Remember to allocate additional memory for your templates All the memory mentioned must to be reserved within VMware

• Install all the latest versions and support packs for LVM (SP03 available 12/2013)

• Isolate the testing environment

39

7 Key Points to Take Home (cont.)

• Isolate the testing environment• Post-Copy Automation (PCA) part of LVM enterprise edition PCA is shipped within SAP NetWeaver packages and is

deactivated by default Must activate with add-on License Enabler PCAI_ENT

• Work closely with your VMware Administrators There are specific network constraints and role configurations

for setup
