2. Guiding Principles!
To prevent catastrophic failures and assure the quality and availability of the IT
systems, the technology platforms on which to run the same IT systems need to
comply with 6 main principles:
 No single point of failure!
 Redundancy!
 Fault isolation of the failing component!
 Duplication of critical systems!
 Immediate fault containment!
 xpertise management
E
SOLUTION!
Premium leasing of dedicated servers implemented by professional
experts in high quality data centers in Switzerland

5. Data Center FT!
To provide an optimum fault-tolerant platform, the data centers in which the
equipment is hosted must have a level of redundancy of the critical components
that classifies them as:
 Tier III: redundancy N+1!
 Tier IV: redundancy 2N+1!
TIA-942 security data center Tiers classification

8. The Servers!
Minimum high standards to protect servers from failures:
 Hot swap bays: to continue operation during repairs!
 RAID levels: to protect against disk failures!
 Redundant PSU: to make sure power flows constantly!
 Dual or Triple Redundant LAN connection scheme
In addition the servers and equipment shall be fully customizable to allow IT Managers
and System Administrators to choose the right solution given the specific needs related
to fault tolerance levels of the IT systems to be outsourced or duplicated.

9. Internet Connectivity!
To assure constant uptime of the IT system, the equipment must be connected to
the Internet through multiple ISPs and at least one Tier-1 carrier.
 edundant connection to ISPs !

10. Switzerland!
A remote risk-free location is ideal in implementing the Disaster Recovery plan
through duplication of the critical applications and thus making operations
tolerant to even catastrophic failures.
 Excellent IT infrastructure
 Direct connection to European backbone fiber!
 Political stability and effective public institutions!
 In the middle of Europe but beyond the EU control!
