The size entries in the tables are an example for the logical volumes:

Table 8:

Logical Volume Size Mount Point

lv_hana_shared System memory

/hana/shared

lv_hana_data 3 * System memory

/hana/data

lv_hana_log System memory

/hana/log

lv_usr_sap At least 50 GiB

/usr/sap

Example calculation:

System memory: 96 GiB

● /hana/shared = Size of system memory = 96 GiB

● /hana/data = 3 times the size of system memory = 288 GiB

● /hana/log = Size of system memory = 96 GiB

● /usr/sap = At least 50 GiB = 50 GiB

Please keep in mind that the above sizes are in GiB (2^30) and not in GB (10^9). This is important because

usually the size of the memory is measured with a base of two, while disk space is usually calculated as a

decimal number.

4.7 Appendix G - Configure a PXE Server

To install the underlying RHEL for SAP HANA, you can set up a PXE environment for automatic installation of

the bare metal machine. For the rest of this chapter, we use placeholders to replace the placeholders in

brackets with the corresponding values of your environment.

To set up provide a PXE environment, the following packages have to be installed on the server which provides

the PXE environment:

● dhcp

● syslinux-tftpboot

● tftp-server

● syslinux

● pykickstart

● The PXE server has to be inside the IP range of the network used to install the systems. You have to modify

the network configuration for this host.
