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

• 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 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
