QUESTIONS & RÉPONSES
3 EMC CONFIDENTIAL—INTERNAL USE ONLY EMC CONFIDENTIAL—INTERNAL USE ONLY
HANA INFRASTRUCTURE : THE KEY DESIGN TOPICS
HANA instances size and usage
(BW or SoH)
Scale-up or scale-out ?
Mutualization (MCOS, MDC, VMWare) ?
Appliance or TDI ?
Data Tiering ?
External Storage choice ?
Backup
Strategy ?
High Availability
and Disaster
Recovery ?
Certified server (E7)
or supported server (E5) ?
4 EMC CONFIDENTIAL—INTERNAL USE ONLY EMC CONFIDENTIAL—INTERNAL USE ONLY
HANA INSTANCES SIZE AND USAGE
• Usage : BW or SoH ?
• Environments: production, pre-production, integration, test, dev, …
• How are the non-prod environments refreshed ?
• Include growth
• Archive old data before migrating to HANA ?

6 EMC CONFIDENTIAL—INTERNAL USE ONLY EMC CONFIDENTIAL—INTERNAL USE ONLY
SCALE-UP OR SCALE-OUT
• The rule « Scale-up first, then Scale-out » is not automatically the best technical and economical choice
• Cisco UCS greatly simplify deployment and operation of HANA Scale-Out
• HANA Scale-out natively includes H/A (host auto-failover)
• SoH scale-out is in controlled availability
• Beyond 4 sockets, server price is exponential
• Large server = long boot time

Virtualization VMWare
MDC (Multi-tenant
Database Container)
MDC-enabled
Tenant Tenant
9 EMC CONFIDENTIAL—INTERNAL USE ONLY EMC CONFIDENTIAL—INTERNAL USE ONLY
HANA HARDWARE MUTUALIZATION TECHNIQUES
• Carefully evaluate operational constraints before choosing a mutualization technique !
• Multiple productive HANA VMs now supported on Vsphere 5.5
• HANA MDC still has limitations

11 EMC CONFIDENTIAL—INTERNAL USE ONLY EMC CONFIDENTIAL—INTERNAL USE ONLY
APPLIANCE OR TDI ?
• Understand the differences
• HANA TDI on Cisco UCS is similar to a Converged Infrastructure (vBlock)
• Cisco offers the same support service for appliance and TDI

WHAT NEEDS TO BE BACKED UP?
• HANA System Backup includes:
– HANA Data Backups
– HANA Log Backups
– HANA Backup catalog
• But does not include:
– Content of the HANA Log files for the last transactions not yet backed up
– HANA Configuration files
– OS Image + OS configuration files + HANA binaries
• What about applications other than HANA? – Currently possible to have Netweaver and HANA on the same server

HIGH-AVAILABILITY AND DISASTER RECOVERY
• HA and/or DR are always required for HANA
• Define RTO and RPO for each HANA instance, for HA and DR separately
• What is the current H/A and DR strategy ?
• Techniques available: Host Auto-failover, System Replication, Storage Replication, VMWare H/A
• Re-use pre-production H/W for DR ? Easier with UCS Service Profile !
• Automatic H/A failover ?
• H/A and load balancing (VMWare)
