IBM Power servers are purpose built for data-intensive applications such as SAP HANA and S/4HANA that require large amounts of in-memory computing but still let you maintain the high availability and flexibility required for your hybrid cloud.
An easy way to leverage the superiority of the IBM POWER processor to greatly speed up the table load process during a tenant database restart operation is to increase the tables_preloaded_in_parallel configuration parameter.For HANA v2 SPS05 rev56 or higher, the formula is the greater of 5 or (0.1 * CPU_THREADS); see SAP Note 3014176 - Applying System Size Dependent Resource Limits During Installation or Upgrade(https://launchpad.support.sap.com/#/notes/3014176).For all tenant databases (indexserver.ini) on HANA v2 on Power, increase the "tables_preloaded_in_parallel" configuration parameter in HANA Studio to be a percentage of the number of lcpu on the LPAR. One way to find lcpu allocation is the lparstat command (you may have to run this as root):
