The Growing Need for Availability

• Application availability – No longer a

luxury for any business

• Cost of downtime – Has risen dramatically

in recent years

• Regulatory Compliance – New and

changing laws governing availability

• Server consolidation – Will drive high

availability in the enterprise

The Availability Pyramid

AL4:Continuous Availability

AL3:High AvailabilityClustering/failover

User Interruption.

AL2: RecoveryData Back-up & Data Replication

User interruption.

AL1: ReliabilityHot swappable components, ECC memory

All service stops.

AL0: Unprotected ServersNo redundant system components, no protection for data, application, or OS.

All service stops.

13

Marathon everRun FT

• Flagship continuous availability offering

• Complete hardware redundancy– Compute-through all failures– Ensures zero downtime through minor and major faults– Ensures zero data loss

• Unique innovation in lockstepping– 15 patents, others pending

• Mainframe-class availability (99.999%+ uptime)– Equal to ~5 minutes of unplanned downtime per annum

• Non-Intrusive– Supports any Windows application– No need for cluster-aware versions that cost more

• Lockstep processing, requires 100% identical hardware– Both servers process transactions in parallel

• Both systems completely synchronized– Memory– I/O– Storage

everRun FTHardware/Software Requirements

• Intel-based P4/Xeon or AMD servers

– 2 Processors (Physical / Logical)

– 1 Processor with HyperThreading or Dual-Core

• 512MB RAM (1GB, recommended, max 4GB)

• 2 NICs (3 or 4 recommended)

• 1 NTFS disk drive (2 or more recommended)

• OS options for both CoServer and FT (one for each CoServer, one for the FT)

everRun HA

22

Marathon everRun HAThe Next Generation Availability Technology

• Minimizes downtime

– Applications ComputeThru® most device failures

– Downtime only as a result of a complete server failure

• Scalability & Flexibility

– Highly scalable – 2x, 4x, 8x (physical) SMP

– Up to 32GB RAM

– No need for identical server pairs

• Utilize existing hardware

• Broad Platform Compatibility

– Intel / AMD multi-core CPU designs

– SAN / DASD storage configurations

everRun SplitSite

31

everRun SplitSite®

Survive A Disaster Rather than Recover From One

• Permits geographical separation of CoServers to support

disaster tolerant configurations– Different rooms in a building– Different buildings on a campus– Different buildings in different towns/cities

• Provides necessary integrity for failures where CoServers

are physically separated

32

everRun SplitSite - NetworkingFlexible CoServer Connectivity

• CoServer links can be:

– Dedicated fiber

– Private switched network

– Public internet

• Bandwidth requirements (per link), for fault handling & performance

– Minimum bandwidth = 51 Mbps

– Recommended bandwidth > 155 Mbps

• Latency requirement:

– Maximum latency = 5 msec

– Recommended latency < 2 msec

– CoServers on same IP subnet or vLAN

everRun SplitSite - Quorum Service Protects Against Network Failures

• Service runs on any network-accessible server

• Scenario: Simultaneous break in all CoServer communications (e.g., an errant backhoe)

• CoServer that can communicate with quorum server stays online

• CoServer that can’t communicate with quorum server takes itself offline

• Split-brain operation is avoided while maintaining application availability

• Redundant Quorum Servers– If one quorum server fails,

CoServers elect a second quorum server

– Maximum protection from site disasters
