• 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

•HANA Networking= vNIC tied to Port-Group:

•101_Policy, 102_Policy, 103_Policy, etc.


• 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

☺ 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
