The following section describes how to prepare:
The virtual disk on which the operating system is installed can reside on any datastore that meets the functional requirements, specifically, support for vSphere vMotion.
Create the persistence of production SAP HANA VMs on a datastore that resides on PowerFlex volumes on an SSD storage pool.
Use the SAP Quick Sizer tool to determine the required capacity for the SAP HANA persistence. If the sizing details are not available, we recommend configuring the data and log device sizes based on the memory size of the SAP HANA VM:
For more information, see the Quick Sizer web page.
SAP HANA installations require a file system to store the SAP HANA binaries, trace, and configuration files. This file system is mounted under the /hana/shared mount point.
In SAP HANA scale-up deployments, this mount point can reside on the local system device. Alternatively, you can create a new disk on a datastore, format the disk using the XFS file system, and then mount it under the /hana/shared mount point. SAP HANA requires approximately 1 x the RAM memory capacity for the /hana/shared file system.
After the SAP HANA VM starts, you must format and mount the persistence before you install the SAP HANA software.
Format the data and log devices as follows:
mkfs.xfs /dev/sdb;mkfs.xfs /dev/sdc
mkdir -p /hana/data /hana/log
mount /dev/sdb /hana/data;mount /dev/sdc /hana/log
