EMC and Cisco teamed up for a joint SAP HANA solution• Cisco Unified Computing Servers

for SAP Future-proof platform for SAP HANA Deployments Today– Best scale-out architecture to

support future customer requirements

– Single virtual chassis scales from one to over 300 blades

– Single high performance networking fabric (client, storage, management)

– Single open management interface across SAP infrastructure

CISCO IS THE VENDOR WHO CAN DO THIS TODAY!!!

Do We Still Need Disks with SAP HANA?

What Happens to In-Memory Data in Case of Power Loss?

Do You Still do Database “Commit“ if all Your Data is In-Memory?

How Can You Move theIn-Memory Data to a StandbyNode?

Does your mission-criticalenvironment need:

– Disaster Tolerance?– Infrastructure Repair/Upgrade?

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

Summary EMC and Cisco deliver the optimal choice for SAP HANA

– Flexibility through Multi-Protocols (unifies file and block)– Converged network technology to reduce Cabling & Complexity– Optimum Performance– Optimum TCO– Highest Reliability

SAP HANA Still Requires Disks for Persistence

External Storage Supports High Availability in what SAP calls a “Scale-Out” Installation

– Allows each Node to Become a Worker or a Standby Node– Activation of a Standby Node is Triggered by the HANA Nameserver

EMC / Cicso provide a strong architectural foundation for upcoming SAP HANA features

– i.e. Remote Replication for Disaster Tolerance & Backup
