Marathon EverRUN FT y HA EverRUN FT: “Aplicaciones donde el cliente no puede tener perdida de servicio en entornos físicos. Requiere máquinas exactamente iguales. Máximo 1 CPU por máquina. EverRUN HA: “Alta Disponibilidad para aplicaciones en entorno físico”. Ventajas con respecto al Cluster MS: necesita 2003 Enterprise y Storage Compartido, con EverRun MS Estándar y Storage Local. 12

Comprehensive Solutions Automated Application Availability How do everRun FT & HA work? Patented architecture creates a single virtual server with a fault-tolerant I/O subsystem using two mirrored physical servers ComputeThru® failures vs. traditional failover approaches Intelligent Policy Management – automated vs. scripted

everRun VM Unique Architecture – VM Fault-Tolerance in Software Installs directly onto a pair of Citrix XenServer hosts Thin software layer between hypervisor and VM environment Auto-creates and maintains identical PVM on alternate host “Active” VM is paired with a “Ready” VM Assured recovery if Active VM host fails PVM’s I/O resources are transparently paired Aggregated across both XenServer hosts Fully redundant networking & storage “ComputeThru” device failures Availability Manager attaches to each PVM Mini Linux VM, manages I/O redirection Automated error detection, fault handling

Flexibility to “Dial-in” Availability by VM Simple “click-through” operation to protect VM’s Future product releases will allow different protection levels for each VM Choose appropriate level of availability per application 16

Citrix XenServer and everRun VM Level 3 - everRun VM System-Level FT (1H ’09) Level 2 - everRun VM Component-Level FT (Available now) Level 1 – Citrix XenServer 5.0 HA (everRun VM Basic Failover) Citrix XenServer Enterprise AL4 AL3 AL2 AL1 AL0 Here we build our way up the pyramid showing how Citrix and Marathon complement and add value to each other. Citrix XenServer Enterprise addressing the requirement for server consolidation of AL0 and AL1 applications Level 1 – XenServer HA address the availability requirements for AL2 applications as well as some AL1 applications Level 2 – everRun VM offers fully automated component level fault tolerance and automated fault management for AL3 applciations Level 3 – everRun VM Lockstep option offers full system level fault tolerance for niche applications that require no interruption, typically non infrastructure applications. 17

everRun VM - Key Benefits Summary Available Zero downtime due to subsystem failures Patented “ComputeThru” technology ensures transparent fail-out of devices No complex failover management or testing No false failovers Mirrored storage for zero data loss Affordable Allows consolidation of multiple business-critical applications Priced for broad adoption No shared-disk subsystem or SAN required Automated Easy to install, operate and maintain “Point and click” operation Automated fault handling and policy management Active redundancy provides assured recovery on host failure No scripting or custom coding Protection for your Citrix XenServer environment SQL Exchange Oracle
