Architecture decision	Requirement	Decision	Rationale
Primary Storage - Production	Tier 1 - 10 IOPS	Flash Storage from IBM FS9000 series devices	* Tier 1 HANA DB on Production \n * Recommended for large non-HANA DB \n * Maximize performance and optimize costs for peak IOPS workload \n * Using of a mix of Tiers is not supported
Primary Storage - nonproduction	Tier 3 - 3 IOPS	Flash Storage from IBM FS9000 series devices	Recommended for all non-DB tiers (App. Servers) including noncritical DB LPARs
Backup Storage	Backup storage for servers	Bare Metal with local disk	Bare Metal on classic offers profiles to accommodate larger storage sizes.
		Block storage	Cloud Object Storage for offsite 2^nd^ copy for lower costs
		Cloud Object Storage	Combine Block and Cloud Object Storage for long-term needs
Data or Storage Migration \n For more migration information, see Moving SAP Workloads	Migration tools from existing environment to PowerVS	Migration tools from existing environment to PowerVS	Image import obviates the need for testing and is useful for nonproduction or POC systems
		DB DR Replication	Using Native DB Replication minimizes the need for testing efforts
		SAP Standard Migrations Tools	SAP Standard Migration options like SWPM, DMO
		Backup and Restore tools	Aspera for high-speed data transfer ideal for Migrations
		Aspera data transfer	Minimize
