--state NEW --dport 39915 -j ACCEPT

3. Now add the rules for the public company network. This is for remote devices others than the SAP HANA

Studio clients, which need access to SAP HANA.

# /sbin/iptables -I INPUT 2 <COMPANY-NETWORK> -p tcp -m state \ --state

NEW --dport 8099 -j ACCEPT

# /sbin/iptables -I INPUT 2 -s <COMPANY-NETWORK> -p tcp -m state \

--state NEW --dport 4399 -j ACCEPT

4. Then add the rules for the replication services.

# /sbin/iptables -I INPUT 2 -s <REPLICATION> -p tcp -m state \ --state

NEW --dport 39915 -j ACCEPT

# /sbin/iptables -I INPUT 2 -s <REPLICATION> -p tcp -m state \ --state

NEW --dport 3${hana_instance}17 -j ACCEPT

5. Finally (if you are working in a clustered Environment) you have to add the rule for cluster synchronization.

# /sbin/iptables -I INPUT 2 -s <PRIMARY-NETWORK> -p tcp -m state \

--state NEW --dport 39901-39907 -j ACCEPT

4.10 Appendix J - Installation in a Virtual Machine (VMware)

SAP HANA in combination with RHEL 6.5 for SAP HANA can be installed in a virtual machine operated by a

VMware Hypervisor.

The following prerequisites must be fulfilled:

● The underlying hardware must be certified by SAP's ICC for SAP HANA.

● Do not use memory compression techniques like KSM.

● The maximum memory reserved for the virtual machines should not exceed 90% of the physical memory

of the hypervisor.

● SAP HANA needs the full instruction set of the host CPU(s). Adjust the settings for the VM accordingly.

● RHEL 6.5 for SAP HANA already includes the paravirtualization drivers for VMware . For monitoring and

system management purposes, VMware Tools must be installed and running as well.

● To obtain the best manageability, use the paravirtualization drivers included in RHEL 6.5 for SAP HANA

instead of PCI pass through (VT-d).

● For performance reasons, the SAP HANA file systems should reside on separate VMDK files.

● For tuning the operating environment, see Prepare the Host.
