    Reliability & Availability with VMware

    Geo Redundancy: achieved through deployment of the necessary duplicated Avaya product

    instances at different data centers (residing on but independent of VMware). examples; CM (SC), SM, SMGR, (AES FP4)

    Zero Dropped Calls, Real Time Failover: achieved through current Avaya fail-over mechanisms on Avaya VE. examples; CM (SW dup), SM

    Avaya Fast Reboot High Availability (FRHA): replaced Brief pause in operations associated with a node switchover/failover event,

    plus the time it takes for all virtual machines to boot on the new active server. Provided by System Platform on Server appliances. No System Platform on

    VMware. Avaya FRHA mechanisms are replaced by VMware HA, similar pause of

    operations. examples: AES, SMGR

    Avaya Machine Preserving High Availability (MPHA): not available Provided by System Platform, non-service affecting failover, zero delay. Not available for Avaya applications on VMware (no System Platform) To be replaced by VMware Fault Tolerance in the future. example: AES

  • VMWARE FEATURE DESCRIPTION

  • #CONVERGE2014

    VMware vMotion

    Description: Enables the live migration of virtual

    machines from one host to another with continuous service availability.

    Benefits: Revolutionary technology that is

    the basis for automated virtual machine movement

    Meets service level and performance goals

    Active memory and precise execution state of the virtual machine is rapidly transferred over a high speed network, allowing the virtual machine to instantaneously switch from running on the source ESX host to the destination ESX host.

    VMware Storage vMotion

    Description Live migration of virtual disks from

    one storage location to another without disruption to users

    Benefits Minimizes the need to

    schedule application downtime due to storage maintenance, upgrades, or migration

    VMware High Availability

    Resource Pool

    XDescription: Enables the high availability

    of virtual machines by restarting them on a different vSphere host in the event of a failure

    Benefits: Minimizes downtime and IT

  • DEPLOYMENT BEST PRACTICES

  • #CONVERGE2014

    Flexible Resource Deployments

    Ensure resource requirements are adjusted prior to Powering On Virtual Machine

    Adjusting resources afterwards will cause errors shown to the right

  • #CONVERGE2014

    Design Considerations

    CMM not included in Simplex OVA CMM will have its own OVA with Feature Pack 4

    You can mix physical Avaya appliances with VE guests Example: CM 6.2 Duplex VE with 1 Physical SMGR and

    1 Physical SM at Core. Duplex VE Survivable Core with 1 VE SM at DR location

    S8300 LSPs are supported to register against a CM VE core, however there is no S8300 CM vAppliance

    ESS or Survivable Core servers are supported
