• SAP HANA is an “appliance like“ Pre-Loaded solutionThe key requirements are defined by SAP
Only Intel Xeon X7560 or E7-X870 CPUs
Max. 128 GB memory per CPU socket
Suse Linux Enterprise Server 11 SP1/SP2 only
10 Gbit Ethernet for internal and external communication
Software has to be Pre-Installed by the Solution Vendor
• No resource sharing with other applicationsServer and Storage resources are dedicated for SAP HANA
• One Appliance per SAP HANA System (SID)•For a usual PRD-QAS-DEV landscape three “appliances” are recommended.
•The installation of multiple HANA database instances on the same HANA infrastructureis currently supported by SAP for NON-productive HANA systems (Dev/Test). At leasttwo “appliances” are required if QAS and DEV runs on one together.

HANA Persistence Layer
� Savepoints (Data Filesystem)
–In-memory data written to disk in regular intervals (5 mins default)
� Log Filesystem
–Capturing all DB transactions since last savepoint
–Restore DB from last savepoint onwards
–High IOPS requirement
� HANA Single Node
–Used server internal disks (SSD, Fusion-io, SAS)
� HANA scale-out (multi node)
–Filesystems reside on external storage

• Servers become secure interchangeable hardware components
• Easy to move Database nodes across server hardware
� No LAN, SAN Zoning or any reconfiguration
• Re-purpose hardware based on changing workloads
� Add Application Tier components or upgrade hardware assituation demands

• Cisco stateless computing resolve the “fixed IP address issue” of HANA
• Computing resources at 2nd site used for QA + Dev (Non-Prod)
• Proven storage technologies used to replicated data to 2nd side
• In case of a disaster
1. Stop Non-Prod
2. Deploy service profile
3. Start Prod
• DC Network is a key factor (L2 / L3)
Ready for Disaster Tolerance setup + DT resource used
more efficiently

☺ Unified Fabric: low latency, high throughput, cabling reduced by ½
☺ Scale HANA across multiple chassis without increasing IO latency
☺ Stateless Computing make Servers freely interchangeable hardware components
☺ SAP License Key is bound to the Service Profile and not to the physical blade
☺ Service profiles enable dynamic provisioning and “bare metal” move of appliance between datacenter
☺ High available SAP operation without scripting orgies
☺ HANA specific monitoring software as part of the Cisco intelligent automation
