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
