Introduction
Increasingly, organizations need to be able to handle complex business processes in real-time, whether they
are complex transactional workloads, business analytics, or the new generation of data mining applications. To
support this trend, SAP launched the SAP HANA platform, which is designed to help organizations cope with
the increasing rates of change and innovation by enabling them to respond in real-time. While recognizing
information as an asset to use to make better decisions, the ability to capitalize on data remains one of the
highest priorities for regulated industries.
Converged infrastructure delivers on that need by providing the speed and ability to power SAP HANA while
remaining cost effective. Vblock® Systems seamlessly integrate leading compute, network, and storage
technologies to provide an optimized converged infrastructure solution that ensures secure and predictable
performance through pre-engineered, modular infrastructure. Vblock Systems provide the highest levels of
virtualization and application performance.
Organizations can choose between procuring SAP certified appliance hardware for SAP HANA or leveraging
SAP HANA tailored data center integration (TDI) to capitalize on existing infrastructure investments. Many
operations teams have achieved their goal of getting their SAP HANA deployment up and running using the
certified appliance model. However, these appliances might not integrate well with existing data center
standards or management and operational processes, adding cost and complexity to data center operations.
SAP HANA TDI offers the ability to deploy SAP HANA software on standard Vblock Systems to leverage the
benefits of VCE’s converged infrastructure solutions.
This paper examines how organizations can stay ahead in the ever-changing SAP HANA landscape. SAP
HANA tailored data center integration – enabled by VCE – is designed for rapid technology expansion and
scaling of the Vblock System compute, network, and storage resources. It provides the benefits of the VCE
Experience – built, delivered, and supported by VCE.
Key features and benefits
Organizations can choose to deploy SAP HANA on:

SAP certified appliances, such as the VCE Vblock® Specialized System for SAP HANA® software
(VSS SAP HANA)

SAP HANA certified hardware components, using SAP HANA TDI
The SAP HANA certified appliance model, while stable and predictable, has some limitations including server
and storage flexibility and the ability to use existing data center infrastructure and processes.
The SAP HANA TDI model removes the limitations of the SAP HANA certified appliance model by allowing
flexibility in hardware choice, as it allows use of existing hardware and operational processes. Vblock Systems
offer a range of storage options that are certified for SAP HANA TDI.

SAP HANA deployment options
SAP HANA is a software solution that integrates a number of SAP components including the SAP HANA inmemory database system, SAP HANA studio, SAP HANA client, and SAP HANA Extended Application
Services. These components help improve operational efficiency, agility, and flexibility.
SAP HANA software requires the use of SAP certified platforms to ensure that performance meets SAP
criteria and can provide enterprise-level business continuity with high availability and disaster tolerance.
Organizations considering using SAP HANA for their high-performance in-memory database and data analysis
needs should also consider their ongoing business IT operations and processes.
When choosing SAP HANA deployment, organizations need to consider whether they want to deploy SAP
HANA on a dedicated infrastructure (appliance) or use their current infrastructure landscape.
SAP HANA certified appliance
Traditionally, SAP HANA has been delivered and installed as an appliance.
The appliance is a fully integrated hardware and software solution in which all the hardware is dedicated to
running SAP HANA software. It comes with all the necessary components pre-configured and provided by
certified SAP HANA hardware partners. VCE’s SAP HANA certified appliance is the Vblock Specialized
System for SAP HANA. Optimized for SAP HANA software, the system represents best-of-breed compute,
network, and storage components from Cisco and EMC.
Appliance delivery of SAP HANA is standardized and highly optimized. Memory requirements drive the system
size and number of nodes. The appliance is easy to use with preconfigured hardware and preinstalled
software, and is fully supported by SAP. It provides stability and predictability; however, it might introduce
some limitations regarding hardware flexibility and might require changes to established IT operation
processes. As this is a preconfigured system, the SAP HANA certified appliance does not allow for change or
additional use. The appliance supports only a single SAP HANA database instance in production. Multiple
production SAP HANA database instances require multiple separate appliances.

SAP HANA tailored data center integration
SAP HANA TDI lets an organization run SAP HANA as part of a certified server, network, and storage
solution. SAP HANA users can leverage existing hardware and infrastructure components for their SAP HANA
environment.
Instead of using the fixed components delivered with an SAP HANA certified appliance, SAP HANA TDI
enables the reuse of certain hardware and infrastructure components already existing in an organization’s
landscape. Best-of-breed certified storage, certified servers and networking components can be combined–
even using their own existing components to support their SAP HANA TDI installation. Organizations with an
existing Vblock System or considering implementing a new Vblock System can deploy SAP HANA through
TDI on a standard Vblock System, provided that certified SAP HANA TDI compute and storage components
are included.
SAP HANA TDI offers a more open, flexible approach to integrating SAP HANA in the data center. Reusing an
existing Vblock System or EMC storage can reduce hardware and operation costs. Enabling SAP HANA
software to leverage existing IT management processes for SAP HANA software implementation mitigates
risks and optimizes time-to-value. Using SAP HANA TDI helps organizations stay within IT budget, shortens
implementation cycles, and allows better consumption of hardware innovations to drive the adaptation of SAP
HANA.
Using an SAP HANA TDI-ready Vblock System removes concerns about configuration complexity due to too
many choices from multiple vendors. With TDI, SAP HANA software is deployed on Vblock Systems following
a strict set of rules defined by SAP. These rules define what servers can be used and how the storage must be
configured to ensure that the hardware delivers the required performance. The SAP HANA software can be
self-installed, installed by VCE, or installed through any SAP services partner with certified staff. The resulting
solution is supported by SAP and VCE.

Virtualized SAP HANA
Virtual SAP HANA is SAP HANA running on a VMware vSphere virtual machine. VMware-based virtualization
of SAP HANA enables the easy deployment and maintenance of production and non-production SAP HANA
workloads, subject to the limitations of the SAP HANA TDI certification process.
The following are the prerequisites and conditions for installing virtual SAP HANA:

SAP HANA 1.0 SPS 05 and later is supported on VMware vSphere 5.1 for non-production use

SAP HANA 1.0 SPS 07 and later is supported on VMware vSphere 5.5 for production and nonproduction use

Each SAP HANA instance deployed on a virtual machine should be sized the same as SAP HANA
deployed on bare metal physical SAP HANA certified appliances

Only single node (scale up) SAP HANA deployments are supported; multi-node scale out
deployments are not supported

Over-provisioning of RAM or CPU is not allowed for SAP HANA
For more information on SAP HANA on VMware on non-production systems (development, test, QA, training),
see SAP Note 1788665 – SAP HANA Support for VMware Virtualized Environments.
For more information on SAP HANA on VMware on production systems see SAP Note 1995460 - Single SAP
HANA VM on VMware vSphere in production.
Choosing between physical and virtual SAP HANA
deployment
With SAP HANA TDI, organizations can choose between additional flexibility by running virtual SAP
HANA, maximum performance by running SAP HANA on bare-metal physical hardware, or a combination.
Deciding which solution is the best fit is largely a question of business processes and organizational
strategy and expertise. For example, if your data center uses a Vblock System 720 with EMC VMAX
storage and EMC SRDF replication for disaster tolerance, you could integrate SAP HANA into that
environment by deploying SAP HANA on a TDI-ready Vblock 720. If your data center policy is to
consolidate and virtualize all workloads and manage them with VMware vCloud Suite, virtualizing SAP
HANA is a good solution.
For fast performance, using physical servers avoids the overhead of a hypervisor. For continuous operations
without downtime, virtualized SAP HANA allows SAP HANA to migrate from one server to another while
keeping it running, thus freeing the hardware for maintenance or updating. In addition, disaster tolerance is
possible with VMware Site Recovery Manager. The performance overhead of virtual SAP HANA varies but is
typically less than 12%. If the SAP HANA database system makes a process run 100 times faster on physical
hardware, it might run only 90 times faster on virtual; however, for most use cases that is more than sufficient.
For training systems, VMware snapshot functionality is a key feature that enables the SAP HANA server state
to be saved and restored at any time. This allows a return to the original state at the end of a training session.
Do not confuse VMware snapshots with SAP HANA snapshots (an SAP HANA functionality).

Tailored data center integration-ready Vblock
Systems
The Vblock System is essentially one hardware component – pre-engineered, pre-validated, and pre-tested to
work together. SAP HANA can be installed with a virtualization layer or without one using an SAP HANA TDIready bare-metal physical Vblock System. Using a TDI-ready Vblock System frees organizations from
worrying about whether their infrastructure will pass the SAP HANA hardware configuration check tool. With
SAP HANA TDI, the SAP HANA database becomes just another resource to consolidate onto a shared
infrastructure. It is treated like any other SAP supported database, run on shared hardware alongside those
databases, the SAP application tier, and other supporting third party applications.
SAP HANA TDI-ready Vblock Systems are standard Vblock Systems with SAP HANA certified servers and
storage. The Vblock System 300 family comes with EMC VNX storage and the Vblock System 700 family
features EMC VMAX storage. They are factory built in the same way as the Vblock Specialized System for
SAP HANA, following a set of SAP HANA TDI configuration rules. The difference is that an SAP HANA TDIready Vblock System can have additional servers and storage to support other workloads, such as non-SAP
HANA databases, SAP application servers, and other non-SAP workloads.
SAP HANA TDI allows use of either a new or an existing Vblock System for SAP HANA. Organizations can
leverage existing or new EMC VMAX or EMC VNX storage arrays for more flexible storage deployment.
Storage can be used for SAP HANA and other non-HANA persistence, for disaster tolerance, or for other
production and non-production use cases.
When using an existing Vblock System, organizations can add SAP HANA-certified Cisco certified servers
along with additional disk storage, following EMC guidelines to deliver the required infrastructure for SAP
HANA. New or existing Cisco UCS fabrics can be deployed in a number of flexible topologies. Only SAP
HANA-certified Cisco certified blades can be used.
Choosing VCE Vblock Systems provides access to a solution that assists with system management through
support or extended support offerings.
Support model
Organizations can rely upon SAP and VCE to jointly provide support for the SAP HANA TDI-ready Vblock
System and corresponding SAP HANA platform. SAP provides standard support focused upon both HANA
platform components and the dependent operating system configurations. VCE provides standard support
focused on the Vblock System and all components, according to the corresponding Release Certification
Matrix. Our support staff is expertly trained in all aspects of Vblock Systems, and we are committed to helping
protect your investment

VCE Professional Services
All VCE™ Professional Services leverage the combined expertise of ecosystem technology experts in
networking, compute, information management, virtualization, and cloud computing.
Since SAP HANA TDI uses a standard Vblock System, the standard VCE deployment and implementation
services for the platform are required. These include Vframework, where applicable, or hardware expansion
services if the hardware for SAP HANA TDI is added as an expansion to an existing Vblock System. This
provides the logical and physical configuration of the hardware so it is ready for installation of the Linux and
SAP HANA software.
In addition, VCE Professional Services can help with:

SUSE or Red Hat Linux installation

VMware vSphere installation, if the nodes are to be virtualized

Running the SAP hardware configuration check tool (hwcct)

SAP HANA software installation

The cost of this service depends on:

Number of blade servers used for SAP HANA

Number of blade servers to be virtualized and number to remain physical

Number of disk arrays to be used, VNX or VMAX

Number of SAP HANA database instances that need to be created

Whether disaster tolerance is required, and whether it uses system replication or storage replication

If disaster tolerance is required, whether the secondary Vblock System is used to run other SAP
HANA instances (for example, non-production HANA instances)
Mixed workloads in SAP HANA TDI environments
A key benefit of SAP HANA TDI on Vblock Systems is that it allows flexible mixed-workloads to run alongside
the SAP HANA deployment.
When deploying SAP HANA software on a Vblock System using TDI there are potentially three types of
workload within the Vblock System:

Production SAP HANA databases

Non-production SAP HANA databases (test, development, sandbox, and so forth)

Other SAP and non-SAP workloads (SAP application servers, other SAP databases, other non-SAP
workloads)
To ensure maximum isolation of workloads, VCE recommends the following:

Use a separate Cisco UCS 5108 chassis for SAP HANA production, SAP HANA non-production, and
other workloads

For EMC VNX storage, only half the maximum number of production SAP HANA nodes can be
supported in a mixed workload environment

For EMC VMAX storage, use separate VMAX engines for SAP HANA production, SAP HANA nonproduction and other workloads

Data center replication for disaster tolerance
Data center replication allows maintaining operations despite a disaster that leads to the loss of a data center.
SAP support two types of data center replication:

SAP HANA System Replication – this is a function of the SAP HANA software and supports
synchronous and asynchronous replication with an active or passive standby

SAP HANA Storage Replication – this uses underlying storage replication methods, such as SRDF
There are no specific hardware requirements or certifications needed for SAP HANA System Replication. If the
data tolerance system is also used for non-production (DEV, QAS, and so forth), add additional storage
following the same rules as for primary storage.
For SAP HANA Storage Replication, EMC has tested both SRDF and RecoverPoint with VMAX storage and
published the following documents:

Business Continuity Best Practices for SAP HANA Tailored Data Center Integration with EMC
Symmetrix VMAX

SAP HANA TDI with VMAX and RecoverPoint

Design considerations
A typical SAP HANA TDI project lifecycle involves:

Determining hardware and software requirements

Registration

Sizing

Implementation
SAP HANA TDI hardware and software requirements
Server
Only servers that are validated or certified are supported. The SAP Product Availability Matrix lists the SAP
HANA validated appliances up to Westmere processors. Starting with Ivybridge processors, the SAP Certified
Appliance Hardware for SAP HANA lists the SAP HANA certified appliances.
When connecting a certified appliance server to shared enterprise storage in an SAP HANA TDI configuration,
keep the following in mind:

There is no requirement to include any local disks or flash cards that were used as part of the
certification.

Additional Fibre Channel adapters can be added for a boot from a storage-area network.
Storage
All storage devices must have successfully passed the hardware certification for SAP HANA. For more
information, see the SAP Certified Enterprise Storage Hardware for SAP HANA.
Note:
Vblock Systems that use EMC VNX5300, VNX5500, VNX5700, or VNX7500 storage arrays are not
eligible for SAP HANA TDI.

Software
The following combination of software has been tested and verified as working with SAP HANA TDI:

Cisco UCS Manager 2.1

VMware ESXi 5.5

VMware vCenter Server 5.5

SUSE Linux Enterprise Server 11 SP3 or Red Hat Enterprise Linux 6.5

SAP HANA 1.0 SPS07 or later for SUSE Linux; SAP HANA 1.0 SPS08 or later for Red Hat Enterprise
Linux
VCE strongly advises that you do not use earlier releases of these products.
Later releases are useable as long as the combinations are reflected in the Cisco UCS HW and SW
Interoperability Matrix and the VMware Compatibility Guide.
Hardware
SAP defines the main parameters for an SAP HANA solution as follows:

Intel Xeon processor E7-4870 CPU and up to 128 GB per CPU socket maximum, or Intel Xeon
processor E7-4890 v2 CPU and up to 256 GB per CPU socket maximum
–
The SAP HANA installer checks the CPU model and stops installation if the wrong CPU is
installed

10 Gigabit Ethernet or 8-Gbps Fibre Channel redundant storage connectivity

10 Gigabit Ethernet redundant connectivity between SAP HANA nodes

1 and 10 Gigabit Ethernet redundant uplink to applications and users
Registration considerations
Registration with SAP is required to use the network switches inside a Vblock System for SAP HANA network
traffic as well as other application traffic. Contact SAP to request permission and register. Registration is not
required if using shared storage only.
Additionally, SAP permission is required to run more than one virtual machine per host on production with SAP
HANA. Open an SAP support message to initiate this request.
For additional information, refer to SAP HANA Tailored Data Center Integration (TDI).

Sizing considerations
SAP provides a range of tools and guidelines for sizing SAP HANA databases. Sizing considerations are the
same for both tailored data center integration and the certified appliance hardware. Sizing helps determine:

Total memory required for the database and to provide runtime space

Whether the database can scale out or must scale up

The number of blades needed in a scale out solution, depending on the memory per blade

RAM needed for the blades

Required storage capacity
Sizing influences the choice of Vblock System. The Vblock System 300 family with EMC VNX storage offers a
lower-entry cost but offers less scalability, while the Vblock System 700 family has a higher entry cost but
offers increased scalability as additional storage engines can be added to handle more SAP HANA server
nodes. For example, an EMC VNX 5400 can cater up to 10 SAP HANA hosts while an EMC VMAX can cater
up to 12 hosts per engine.
Sizing is a complex topic. VCE maintains a staff of SAP sizing experts who can assist organizations with this
process.
Server sizing
If installing virtual SAP HANA, do not over-commit resources when creating virtual machines on VMware ESX
hosts. This means that all virtual machines on a single host must not be configured with more virtual memory,
RAM, or CPUs than what physical memory and CPUs exist. Also, be sure to consider that the hypervisor
consumes a certain small amount of RAM.
Network sizing
For SAP HANA TDI, the standard networking within Vblock Systems is sufficient:

Unified or segregated networking

Cisco UCS 2204XP or 2208XP Fabric Extender each with 4 x 10 Gigabit Ethernet interfaces to the
Fabric Interconnect

Cisco UCS 6248UP or 6296UP Fabric Interconnect
19

Storage sizing
Each SAP HANA node has a database log volume, database data volume, root volume, local SAP
volume, and shared SAP volume. The storage needs to deliver enough performance for SAP HANA. This
is why certain rules apply to the choice of disk drives and RAID configuration cabling and a certain
amount of disks are needed. This might result in more storage capacity than needed, even if the disk
space is not needed. The number of drives is important to ensure adequate storage performance.
For more information on these rules, refer to the following documents:

Vblock System 700 family rules in the EMC VMAX Configuration Recommendations for SAP HANA
TDI white paper

Vblock System 300 family rules in the EMC VNX Configuration Recommendations for SAP HANA TDI
white paper
Virtual SAP HANA sizing
SAP HANA virtualized with VMware vSphere is sized the same as non-virtualized SAP, with the following
exceptions:



Maximum virtual machine size
–
VMware supports SAP HANA databases in scale up mode, up to the maximum size of a virtual
machine. For example, on VMware vSphere 5.5, this is 64 virtual CPUs and 1 TB virtual memory.
–
VMware states that the virtualization overhead for SAP HANA is less than 12% (SAP HANA on
VMware vSphere 5.5 for Production Environments).
Virtual CPU to physical CPU mappings
–
Intel processors use hyper threading, which increases performance.
–
VMware recommends enabling hyper threading when running virtual SAP HANA. This doubles
the effective number of physical CPUs, meaning more virtual CPUs can be allocated to use all
available resources.
Memory overhead
–
Virtual machines have full access to and use the amount of memory assigned to a virtual machine
when created. Memory is used by the VMware ESXi hypervisor and virtual machine memory
overhead. The host must have an amount of unassigned memory for the hypervisor RAM.
–
For 512 GB RAM, the dynamic memory overhead is typically around 2 GB. For more information,
refer to SAP HANA TDI on Cisco UCS and VMware vSphere.
SAP HANA databases are sized the same way for physical and virtual environments.

Implementation considerations
The following diagram provides an overview of the implementation steps:
This section provides Vblock System-specific implementation information.
Setting up the SAP HANA landscape
Storage considerations
The storage on SAP HANA TDI systems and TDI-ready Vblock Systems must meet specific requirements.
The storage used must be listed in one of the following documents:

SAP Product Availability Matrix (PAM), which lists all validated appliances

SAP Certified Appliance Hardware for SAP HANA, which lists all certified appliances

Listing of certified SAP HANA TDI storage, located at SAP Certified Enterprise Storage Hardware for
SAP HANA.

Special configuration requirements for EMC VNX storage are listed in the EMC VNX Configuration
Recommendations for SAP HANA TDI white paper. Special configuration requirements for EMC VMAX
storage are listed in the EMC VMAX Configuration Recommendations for SAP HANA TDI white paper.
Once storage is set up, check its performance. The same test tool is used to validate both SAP HANA TDI and
the SAP HANA certified appliance, with slightly different KPIs. SAP Note 1943937 provides documentation on
how to download the latest version of the test tool and run the tests.
Compute considerations
The BIOS settings are the same for both virtual and physical installations of SAP HANA. For more information,
refer to SAP HANA TDI on Cisco UCS and VMware vSphere.
Networking considerations
An SAP HANA data center deployment can range from a database running on a single host to a complex
distributed system with multiple hosts located at a primary site and one or more secondary sites and
supporting a distributed multi-terabyte database with full high availability and disaster recovery.
SAP HANA has different types of network communication channels to support the various SAP HANA
scenarios and setups, including client zone, internal zone, and storage zone.
Before installing SAP HANA, use the hwcct tool to check the networking component to ensure the
hardware and the configuration are operating properly. In order to get the required performance, all
network communication must allow for jumbo frames (network packets with a size of 9000 bytes).
Fully redundant switches and routers are recommended and are included as standard in Vblock Systems.
Virtualization considerations
SAP HANA can be installed as an SAP HANA TDI project on VMware for test and production use.
However, many restrictions apply when running SAP HANA on VMware for production use (see SAP
Note 1788665 – SAP HANA Support for VMware Virtualized Environments for non-production use and
SAP Note 1995460 - Single SAP HANA VM on VMware vSphere in production for production use of SAP
HANA on VMware).
The VMware ESXi host provides the platform on which virtual machines run. The Cisco service profile contains
the hardware configuration in a Cisco UCS environment. Use service profile templates or VMware vSphere
auto deploy to ease the VMware ESXi deployment process. For more information, refer to Implementing
VMware vSphere 5 Auto Deploy on the Cisco Unified Computing System.
For each vSwitch, it is recommended that two uplink interfaces with MTU 9000 as the trunk be configured. The
VLAN assignment takes place in the port group configuration of the vSwitch.

Validating the landscape
The SAP hwcct tool is used to verify that all is set up correctly and delivering the required performance. This
tool is described in SAP Note 1943937 - Hardware Configuration Check Tool - Central Note. It is available
independently of SAP HANA and contains tests for the SAP HANA landscape, file system, and network.
Installing the hwcct tool takes about one hour. Running the long test in a 3+1 landscape (three workers and
one standby) takes five to ten hours. In a larger environment, it is best to schedule it to run over a weekend.
Installing SAP HANA
Once the landscape is validated, SAP HANA can be installed. An SAP-certified SAP HANA Installation
Technology Specialist must supervise the installation. VCE Professional Services can help with this process.
The SAP HANA Server Installation and Update Guide describes the SAP HANA database server
installation. When following it, be aware that VCE has tested all SAP HANA failover mechanisms using
the Storage Connector API.
Post-production maintenance and support
Supporting an SAP HANA environment requires management of the following components:

Firmware patches

Operating system patches

SAP HANA platform component patches

Peripheral component patches
Choosing Vblock Systems for an SAP HANA TDI solution provides access to the VCE Release Certification
Matrix and VCE seamless support. The Release Certification Matrix (RCM) provides a fully tested firmware
and software stack including VMware vSphere for virtualized servers and up to the firmware for physical
servers. The RCM is regularly updated and provides an upgrade guide to help with the upgrade or VCE can
perform the upgrade as a chargeable service.

Conclusion
SAP HANA software can be deployed on SAP certified appliance hardware or installed through SAP HANA
TDI. Organizations can choose between procuring a dedicated SAP HANA certified appliance and tailoring the
SAP HANA installation to their data center. While the SAP HANA certified appliance provides stability and
predictability, SAP HANA TDI offers more flexibility as it allows a selection of hardware that integrates it into
existing processes, instead of having to adapt processes to fit with the appliance hardware.
Both VNX-based Vblock 300 family and VMAX-based Vblock 700 family systems provide a pre-engineered,
pre-validated, and pre-tested platform on which to run SAP HANA. This platform comprises the storage,
networking, compute, and optionally, the virtualization layer. It is supported as a single product, meaning there
is no need to worry if the support issue was caused by a networking, storage or compute component. The
platform provides a stable and reliable base for an SAP HANA installation. With SAP HANA TDI, organizations
can consolidate SAP HANA workloads alongside both SAP and non-SAP workloads on the Vblock Systems
shared infrastructure.
Virtual SAP HANA adds to the benefits of SAP HANA TDI, making it easier to upgrade or maintain hardware,
and allowing the use of monitoring software.
For fastest performance, choose bare-metal physical hardware. For continuous operations without any
downtime, virtualized SAP HANA allows SAP HANA to migrate from one server to another while keeping it
running, thus freeing the hardware for maintenance or updating.
