What are the key migration considerations?
Traditional hosting vendors sell shared systems as a cost cutting measure.
Client A Client C Client DClient B
Shared SAN Shared Tape Backup
Dedicated vs. Shared Systems
Traditional – Shared Systems
Dedicated vs. Shared Systems
Inherent Risks of Shared systems
SecurityIs it a compliance issue if you share back-up tape with another organization?
PerformanceCan you afford slow performance because another organization is sharing your system?
DowntimeCan you afford an unplanned outage because of another customer’s problems?
Can you afford downtime because another customer requires maintenance?
Economics have changed – Servers that used to cost $500K are now only $25K - $50K
Dedicated vs. Shared Systems

Dedicated systems reduce the risk of security issues, performance issues, and unplanned downtime
Pay by the Rack vs. Pay by the Gigabyte
Traditional - Pay by the Gigabyte
40¢ per GB per month backup fees?5 GB email application, nightly backups =
$62/month
Typical SAP ECC landscape300 GB DEV
800 GB QAS
800 GB PRD
1.9 TB, nightly backups = $23,560 per month!
Now add BW/CRM/Portals!
How big will your system be next year?
Pay by the Rack Vs. Pay by the Gigabyte
Sym-Hosting - Pay by the Rack
Don’t get penalized when your business grows
No budget blow-outs when you know what costs to expect.
Hardware Constraints vs. Flexible Infrastructure Options
Traditional – Hardware Constraints
Watch for hidden agendas Only support certain types of hardware
Benefit when you buy hardware from their partners.
Hardware Constraints vs. Flexible Infrastructure Options
Sym-Hosting – Flexible Infrastructure Options
Flexible equipment purchasing modelJointly specify servers and infrastructure
Client purchases equipmentDepreciation benefits
Leverage vendor relations
Symmetry purchases equipmentOne stop shop
100% transparency on H/W costs
Purchase what you need

What are the key migration considerations?
Key Migration Considerations
Type of migration – Logical or Physical / Heterogeneous or Homogeneous
Number of systems to be moved – impacts space required and timeline
3rd party applications/systems that will communicate with hosted systems
Network requirements – bandwidth and number of locations
May coincide with certain SAP projects (homogeneous or heterogeneous system copies, SAP upgrade, implementation of additional SAP products, etc)
Key Migration Considerations – Types of Migration
Logical Migration- Movement of SAP application data to new servers at Symmetry’s datacenter- Purchase of new server equipment- Combination of tape/USB drive transfer and log shipping
Physical Migration- Movement of existing physical servers to Symmetry’s datacenter- Use of transition “Bumper Box” for production system - Certified shipping company- Full system backups still create prior to shipment
New Implementation- New hardware shipped directly to Symmetry- Symmetry performs SAP installations and Basis implementation support
Combination- Chance are that a combination of the above will be used for each landscape

Key Migration Considerations – Example Migration Process for a Production System
Build copy of production system on a separate piece of hardware (either temporary loaner or new system)
Test/validate functionality
Start ftp’ing transaction logs to Symmetry datacenter
Make backup of “old” production database to common media format or USB drive
Ship backup to Symmetry data center
Restore backup to “new” production server
Apply transactions logs
Stop “old” production server
ftp last log to Symmetry datacenter
Apply last transaction log to “new” production server
Start SAP instance at Symmetry Datacenter
