Secure-24 & VMware
» Secure-24 is a vCloud Powered cloud &
hosting provider
» With the VMware vCloud Powered service
offerings, clients benefit from the
performance and agility of cloud computing
without compromising security
» Secure-24 and VMware partner to offer
SAP HANA in a virtualized environment
4
Agenda
» Faster Time-to-Production. Eliminate the delays of purchasing and
installing on-premise hardware.
» Speed, Agility and Reliability. Experience the entire SAP® landscape
running at the speed of business.
» Predictable Costs. Transform large capital expenditures into a single
monthly operational expense.
» Lower Total Cost of Ownership. Lower costs by simplifying complex and
expensive IT architectures -- hardware cost avoidance.
» Right-sizing Your SAP HANA Landscape. While maintaining SLAs using
workload management techniques.

Highlights
Lead time for deployment and installation with increased
uptime and improved DR
No need for hardware refreshes and no upfront capital
costs
High availability, simplified.

Rapid Deployment of SAP HANA Databases
VMware Templates and Clones
• A clone is a copy of a virtual machine
• A template is a master copy of a virtual
machine
- Used to create many clones
Ex: SAP HANA Template
• Rapid deployment
- rpms, OSS notes, kernel parameters
• SAP Unified Installer
- SAP HANA, SAP HANA Studio, Life Cycle
Manager, Application Function Library (AFL), SAP
HANA Database Client
SAP HANA Customer Proof of
Concepts
• Use of VMware Templates for Multi-VM CA

SAP HANA Overview
» SAP HANA is an in-memory data
platform
On-premise
• As Appliance
• Enterprise Storage -Tailored Datacenter
Integration (TDI)
In the cloud, or as a hybrid of the two
ACID Compliant
» SAP HANA platform for performing
Both real-time analytics & transaction
workloads
» Database and Application Logic
In-memory engine to transform
transactions, analytics, text analysis,
predictive and
spatial processing
» Perfect to run on VMware vCloud Suite

The Reality of Running SAP Workloads on VMware
In the transactional world:
» Bursty sub-seconds workloads
» SAP ASE, Replication Server
– 10% of 250mSec is negligible
– Is it even measurable at the application
layer?
In the world of SAP HANA:
» Analytic or mixed workloads
» Example response times
– Without SAP HANA = 4620 seconds
– With SAP HANA = 14.5 seconds
– SAP HANA on vSphere = 16 seconds

It’s the same SAP HANA software
you’re used to in a dedicated
environment, but now it’s virtualized.

Mission Critical: Zero Downtime Migrations
VMware vMotion
• Move running virtual machines across ESXi Server
Live Migrate SAP HANA Databases
• Zero downtime maintenance
• Migrate live databases
• Little impact to users
Critical For In-Memory Databases
• Preserves the entire state of memory
• Avoid a database – loses temp tables, computations
VMware vMotion – All or Nothing
• Like an atomic transaction; completes or does not complete
• Does not leave VM in phantom state

VMware Distributed Resource Scheduler (DRS)
Distributed Resource Scheduler (DRS)
• Align IT infrastructure with business goals
• Dynamic allocation of compute resources
Managing SAP HANA databases
• Database workloads are both dynamic and transient
• Directs compute resources where needed
• Maintain database response times and SLA’s
DRS Automation Levels
• Manual – recommend initial placement and migrations
• Partially automated – initial placement automated; recommend migrations
• Fully automated – automated placement and migrations

VMware Easy Button DR
Hypervisor based - Virtual Machine Replication
• Reduced complexity and streamlined IT operations
• Infrastructure agnostic
• Simplified, non-impactful DR testing
• Complete stack replication including OS, application and database
• Automate the entire failover and failback process
17
Highlights
Scale a virtual SAP HANA environment in 64 GB increments
Leverage dynamic storage tiering to reduce memory
requirements or hold memory sizing in place as SAP HANA
database size grows
VMware HA provides intrinsic cost savings for HA

Evolving: SAP sizing much more precise
» VMware vRealize Right Sizing
SAP HANA BlueMedora Plug-In
Monitor memory and vCPU utilization
Add/Delete resources
• Underutilized – Deploy more SAP
HANA
• Over utilized – SAP HANA unleased
Workload management – vMotion/DRS
» Determine Consolidation Ratios
No over commitment and actual usage
characteristics
» Right Sizing
Do not stray from SAP sizing
recommendation
Right sizing over time – needs workload
monitoring & confidence ratios
Monitored CPU and Memory utilization during performance
testing
Consistent Memory Overhead SAP HANA on vSphere
Peak Disk Usage and Latencies

Conclusions
» SAP HANA on vSphere is fully supported in production and has
great performance.
» Rigorous joint testing by SAP and VMware over two years found
zero functional errors with a 100% pass rate.
» Combining SAP HANA and vSphere provides additional benefits
with regards to deployment and availability.
» Some remaining customer slots for SAP on SAP HANA controlled
availability Proof Of Concepts
EVERYTHING IS AWESOME!!!!!

Top Takeaway Points: Why it makes sense to
virtualize SAP HANA
Common Questions VMware/Secure-24 Responses
“How can I have HA within my
budget?”
• Intrinsic HA & DR built into VMware
“Does my organization need a 256 or
a 512? Is there anything in between?”
• Ability to scale up in 64 GB
increments
“We have a 256 today, but my
organization is growing”
• Quickly scale up or down,
depending on business need
