IntroductionThe following installation documentation provides information about all required steps to setup a SAP NetWeaver based system on SimpliVity OmniStack. The example shown is based on SUSE Linux OS (SLES4SAP Edition) and SAP’s Sybase ASE database together with SAP NetWeaver 7.5

AudienceThe target audience is technical engineers responsible for SAP landscape design and installations.

A user account for SAP’s support portal will be required to view the hyperlinks to SAP’s support portal.

Virtual Machine PlanningThe following section provides details around Virtual Machine sizing and configuration that should be planned for before actual deployment.

VM SizingThe size of the VM(s) for your SAP landscape is impor-tant for the system’s performance and you can adapt the resources of each VM.

In general, for SAP systems, we recommend a maximum size of 128GB memory per VM. If you need more resources, you should consider adding additional application servers to your SAP system in separate VMs.

Sizing requires an iterative process to adjust the resources – but you can start with our example sizing in list below.

Define VM disk layoutFind detailed information in VMware’s document:

http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/sap-sybase-adaptive-server-enterprise-on-vmware-vsphere.pdf

A crucial point is to use multiple paravirtual SCSI adapters to connect the virtual disks. This improves system performance, especially for the disks for database files and transaction logs.

This is provided in the section “Create virtual machine”.

The following list can be used as an example:

Type Virtual Device Virtual SCS Driver

Size Mountpoints / Partitions

OS, SAP + ASE binaries 0:0 LSI logic 120GB /Swap(1 Partition)

ASE data 1:0 Paravirtual 100GB /sybase/SID/sapdata/sybase/SID/saptemp(2 Partitions)

ASE log 2:0 Paravirtual 15GB /sybase/SID/saplogASE archivelog 0:1 LSI logic 150GB /sybase/SID/saparch

Deployment and ProvisioningThis section provides deployment and provisioning details for creating a Virtual Machine to run SAP NetWeaver along with a Sybase ASE database.

Create virtual machine1. Select one of your datacenters and click the button for ‘add VM’.

2. Select ‘Create a new virtual machine‘

3. Enter a name for the VM – the planned hostname for example.




4. Select a cluster or a host where to place the VM.

5. Select an OmniStack datastore.




6. Select ‘ESXi 6.0 and later’ if you are on ESXi 6.0

7. Select an Operating System and version.




8. Configure and Memory according to your requirements and configure your first Hard disk. This disk is recommended to be used for OS and binaries on SCSI port 0:0 – see example list in section “Define VM disk layout”.

9. Add a SCSI controller “VMware Paravirtual”

10. Add another hard disk and set the new SCSI controller (1:0) for it.




11. Continue with adding SCSI controllers and hard disk. Use the list from section “Create VM disk layout”.

1.

12. Enter a size for the new hard disk




13. This is an example summary – click ‘Finish’ when done.

14. The VM is ready to be used.




Installation of SLES 4 SAPThis section provides a detailed, screenshot-based information on how to install “SUSE Linux Enterprise Server for SAP Applications” on the VM created in the previous section.

It is recommended to use a SAP specific versions of Linux. These versions are available from SUSE and Red Hat.

Find detailed information here:

1. SAP on VMware vSphere http://scn.sap.com/docs/DOC-27384

2. SAP Note SLES Install notes https://launchpad.support.sap.com/#/notes/1984787

Installation1. Download installation media and upload it to

your datastore.

2. Connect the .iso file of DVD-1 to your VM

3. Power On the VM

4. Open the console window for your VM, you should see the selection screen.

5. Select ‘Installation’ and confirm license agreement.

6. Confirm the license agreement

7. Configure network settings and click Next


http://scn.sap.com/docs/DOC-27384

https://launchpad.support.sap.com/#/notes/1984787



8. Configure Hostname setting and click Next

9. Enter registration information or skip this step to register the installation later.




10. Select Product Installation Mode

11. Choose the correct hard disk for OS installation – see section “Create VM disk layout”




IMPORTANT STEP:

Recommended file system for root partition is Ext4.

Swap space is recommended to be configured with 20GB. This is not possible with the installer – therefore we delete the swap partition from the suggested configuration and configure a swap file later.

12. For SLES4SAP no additional software is required. For other versions, please check recent SAP installation notes.

13. Set your time zone.




14. Adjust installation settings according to your requirements. Example: SSH ‘on’, firewall ‘disabled’, Kdump ‘disabled’ and default systemd target ‘Graphical mode’ Select ‘Install’ when done and wait for installation process to finish – OS boot at the end should happen automatically.

15. You can now log on via SSH and continue with the mandatory post-installation tasks to configure the host.

Linux OS Post-Installation tasksIn order to configure your linux OS according to all require-ments, we need to make a few configurations changes. The

“4 SAP” versions of the Linux distributions SUSE and Red Hat have already preconfigured a lot of parameters etc.

The most important configuration objects are now net-work, swap and disks.

Network interfaces and hostname resolutionConfigure a network card, if not yet done. Or add addi-tional NICs if required.

To install SAP, we need at least one configured NIC with a Mac Address and an IP address.

Recommendation: add your hostname incl. full qualified address to the /etc/hosts file as well – just to be sure you don’t have DNS issues.

SWAP spaceDuring the installation process, we skipped the configura-tion of a swap partition.

Instead of using a dedicated disk or partition, we use a swap file placed on our root device.

1. Create an and add your swapfile with the following commands

saphost:~ # mkdir /swap

saphost:~ # swapon -s

2. Add your swapfile to the /etc/fstab using vi or similar

3. Reboot and check if swapfile is still configured

saphost:~ # swapon -s

Disks, partitions and mount pointsDuring OS setup process, we only configured the disk containing our root partition (incl. our swap file).

Now we have to create new partitions on our other hard disks, format them with file systems and mount the partitions to our system – see again the table in section “Define VM file system layout”.

Provide SAP installation media and documentationRead the most recent version of installation guides for your SAP software product and determine the required installation media. You will require login credentials and download authorization in SAP’s support portal.

Typically, you will need at least following types of install media:

- Software Provisioning Manager (SWPM) in most recent version

- SAP Kernel

- SAP Kernel Patch

- RDBMS

- RDBMS Client

- Installation export for your software product

- SAPCAR binary for your platform, to extract the SAR-archives

Download everything and provide it on the server. Using CIFS mounts for accessing installation media is NOT recom-mended.

After uploading to the server, you have to unpack all ZIP and SAR archives.




Start SAP software installationFor single installations, we recommend using SWPM in graphical mode.

You can start SWPM from the graphical mode of your Linux distro – or you start a VNC-server and connect, or use any other method which gives you X-Window output.

Following information should be prepared before you start:

1. SAP system ID (SID)

2. SAP instance numbers for ASCS and PAS instances

3. Full qualified hostname

4. Linux UID of <sid>adm user

5. Linux GUI of group sapsys

6. Linux UID of syb<sid> user for Sybase (different for other DBs)

7. Linux UID of sapadm user

8. Passwords for all users

9. SLD connection information (if SLD available)

The UIDs and GIDs can also be auto-chosen by the installer, if you don’t have any preference. If users are already created, the password and the UIDs are not changed. Only the group assignment is updated if necessary.

The following screenshots show a sample installation on our previously created VM ‘saphost’. We install NetWeaver 7.5 with instance number 00 (PAS) and 01 (ASCS) with Sybase ASE 16 as a central installation (SAP instances and DB on same host) using the SWPM tool.

Notice the assignment of the mounted filesystems we defined in the section “Define VM disk layout”.
