12. 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.

13. Comprehensive SolutionsAutomated 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

15. everRun VMUnique 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

16. 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

17. Citrix XenServer and everRun VM Level 3 - everRun VM System-Level FT (1H ’09) AL4 Level 2 - everRun VM Component-Level FT (Available now) AL3 AL2 Level 1 – Citrix XenServer 5.0 HA (everRun VM Basic Failover) AL1 Citrix XenServer Enterprise AL0

18. 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
