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. 12

13. 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

15. 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

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 16

17. Citrix XenServer and everRun VM

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
