What is this about?
• SAP HANA provides built-in multi-tenant support,
whereas every database tenant represents a dedicated share of an SAP HANA instance data,
configuration, user management and properties.
• A viable alternative to DB tenants is the use of virtualization technology,
to host multiple isolated SAP HANA instances on one or more servers, enabling each database
instance to appear to run on a separate machine
• Both options offer customers reduced TCO
and additional options for planning and managing their system landscapes.
It also impacts CAPEX positively and hence can for example help to lower the entry barriers for
SMEs and startups to utilize SAP HANA within their business.
• SAP HANA in the Cloud
comes with no CAPEX but OPEX only, operated in dedicated or shared environments, being the
lowest entry-barrier variant

 Cloud-affine SAP HANA Multi-tenant DB Containers capabilities
– Elasticity (shrink and grow tenants, move tenants)
– Security (Separation of provider and customer)
– Optimized for many small tenants (footprint reduction)
– More HW efficiency

SAP HANA Cloud – SPS10 Features With High Impact On Cloud
New Features For Cloud Operations
Improved Cloud (massive-scale) data center support
 Two types of delta backups: Incremental and differential
 Reduction of startup times: rebuild of secondary indexes during reactivation of the RowStore now can be
decoupled / done asynchronously in background
 Integration of SAP HANA Dynamic Tiering into Host Auto-Failover HA capabilities
 Simplified certificate management for SSL/TLS and single sign-on: storing certificates in the database simplifies
the configuration and makes certificate management available to tenant administrators. This is especially
relevant for cloud scenarios where tenant administrators usually do not have access to the file system.
 Multiple Database Container (MDC)
– Extended tenant isolation (OS user / group per tenant DB)
– TREXnet isolation (internal communication, statement permission)
Developer focus
 WebIDE: Close feature gap with HANA Studio

SAP HANA Cloud Platform

Multi-tenant DB Containers
Status & Outlook

SAP HANA Multitenant Database Containers (MDC)
Summary
Multitenant Database Containers provide strong isolation capabilities
 Each tenant database has its own database admin and end users, database catalog,
repository, persistence, backups, traces and logs
 Tenants Memory and CPU consumption can be configured independently
 Integration with SAP HANA data center operation procedures, housekeeping,
backups (full and/or on tenant level), etc.
Multitenant Database Containers share one SID and Revision
 Shared installation of database system software
 Tenant databases are identified by name or port
 SAP HANA system replication covers whole system (Sys. DB and tenants)
 Additive sizing for all tenant database
Targeting MCOS-like on premise and SAP HANA cloud platform
scenarios with a reasonable number of tenant databases per system.

other options for multi-tenancy
Support Status & Outlook

SAP HANA partitioned
Currently Supported HW Partitioning Technology
• In addition to MCOS and MCOD deployment options …
… which may also be considered to achieve multi-tenant like environments.
See SAP Note 1681092 for specific information and constraints.
• … the currently supported HW partitioning technology for running SAP HANA are:
• General support for HP nPartitions in context of HP CS 900 with Superdome X servers
for production and non-production use cases.
See SAP Note 2103848 for more specific information and constraints.
• General support for Fujitsu physical partitioning with PRIMEQUEST 2400 E/L and PRIMEQUEST 2800 E/L
for production and non-production use cases
See SAP Note 2111714 for more specific information and constraints.

SAP HANA virtualized
Currently Supported Hypervisors / Logical Partitioning Technology
• VMware vSphere 5.1 with SAP HANA SPS 05 or later for non-production use cases
• VMware vSphere 5.5 with SAP HANA SPS 07 or later for production and non-production use cases
• In General Availability for single-VM scenarios.
See SAP Note 1995460 for specific information and constraints
• In Controlled Availability for multi-VM scenarios.
Note, that access to this SAP Note is restricted to customers participating in the controlled availability phase.
• In Controlled Availability for SAP BW, powered by SAP HANA scale-out scenarios.
• Hitachi LPAR 2.0 with SAP HANA SPS 07 or later for production and non-production use cases
• In Controlled Availability for single- and multi-VM scenarios.

Controlled Availability Application Process
• Customers interested in running …
• multiple SAP HANA VMs on VMware vSphere 5.5 in production
• SAP BW, powered by SAP HANA on VMware vSphere 5.5. in scale-out and production
• one or more SAP HANA VMs on Hitachi LPAR 2.0 in production
… can apply for Controlled Availability of SAP HANA production support by sending an email to:
sap_hana_tailored_data_center_integration@sap.com
• This email should contain…
• High-level scenario description and timeline (e.g. planned Go-live date)
• Expected database size (compressed HANA DB size, number of users)
• Hardware spec (HW vendor, server t-shirt size),
• Planned HA/DR setup (if applicable),
• Contact details (if possible incl. SAP account number) for further communication
All information provided will be kept confidential and is only used during the selection process. Once accepted, customers will
receive the usual SAP HANA support as also provided for non virtualized environments for the presented scenario.

Currently Supported Hypervisors / Logical Partitioning Technology
The following general constraints and conditions do apply while running SAP HANA virtualized:
• Configuration and overall setup complies with the current version of the "SAP HANA Guidelines for being virtualized" and
the vendor specific best practice documents for running SAP HANA in a virtualized environment on corresponding
hypervisor.
• Each SAP HANA instance / virtual machine needs to be sized according to the existing SAP HANA sizing guidelines and
corresponding hypervisor vendor recommendations. CPU and memory over-provisioning must not be used.
• Beside "SAP BW, powered by SAP HANA in scale-out", the maximum size of a virtual SAP HANA instances is limited by
the maximum size the hypervisor supports per virtual machine and the application dependent core-to-memory ratios.
• The SAP HANA system setup needs to be done by an SAP HANA certified engineer, on SAP HANA certified hardware, and
successfully verified with the SAP HANA hardware configuration check tool (SAP HANA Tailored Datacenter Integration
option). Alternatively, the system can be delivered pre-configured with hypervisor and SAP HANA software installed by SAP
HANA hardware partner (SAP HANA appliance option).
• Nested virtualization (running a hypervisors within another hypervisor stack) is not supported by SAP.
Customers may, however, run virtualized applications on physically separated hardware partitions.

 Support for Multi-VM and Scale-Out in GA

Considerations and tradeoffs
• Virtualization is
usually limited in size
and supported
scenarios (e.g. 1 TB
for vSphere 5.5; in
general no-scale out
as of today)
• MDC supports any
size and scenario
• MDC creates
isolation between
tenants - inside one
DBMS
• Virtualization & HW
Partitioning offers
isolation down to
OS-level
• MDC can handles

• Virtualization & HW

• Virtualization adds

and knowledge.
• A virtual SAP HANA

• HW Partitioning
