SAP HANA

SAP HANA Persistence: In-Memory Data Is Regularly Saved to Disk

• Data:SQL data and undo log information

Additional HANA information, such as modeling data

Kept in-memory to ensure maximum performance

Write process is asynchronously

• Log:Information about data changes (redo log)

Directly saved to persistent storage when transaction is

committed (synchronous)

Cyclical overwrite (only after backup)

• Savepoint:Changed data and undo log is written from memory to

persistent storage

Automatic

At least every 5 minutes (customizable)

Enterprise Storage (TDI)

• Supported storage devices – All storage devices must have successfully passed

the hardware certification for SAP HANA.

• Tool support –SAP HANA HW Config Check Tool (HWCCT) is required to check

data throughput and latency KPIs between the SAP HANA servers and the

enterprise storage.

• Storage Configuration – Perform the storage configuration using the “IBM

System Storage Architecture and Configuration Guide for SAP HANA TDI”

document

• General Information

–Check out the Storage Whitepaper.

–The exam “SAP Certified Technology Specialist (Edition 2014) – SAP HANA Installation”

needs to be successfully passed for a person to perform SAP HANA installations.*

16*SAP HANA hardware partners and their employees do not need this certificate
