Thread: Multi-site replication / failover

  1. #1

    Default Multi-site replication / failover

    Is the following scenario somehow possible:

    (Site1)
    2 x Open-E DSS in active/passive configuration for iSCSI
    Hypervisors (Xenserver) connected to High Available target

    VPN over WAN (100 mbit / ~ 10 seconds latency)

    (Site2)
    1 x Open-E DSS
    Hypervisors (Xenserver) standby

    Setup a replication between Site1 and Site2 (in fact, a second replication). In case a disaster happens at Site1, or major power/network/cooling outage, boot the hypervisors at Site2 and log-on to the replicated targets at Site2 and restart VMs here.

    Citrix Xenserver supports Site Recovery in version 6, which is built upon some sort of replication between iSCSI storage (no matter what storage device) but I cannot see how this fits in with Open-E. Maybe someone can shed a light on this issue. I would really like to also keep the active/passive failover at Site1 to avoid switchover on 'just' storage failure.

    With Volume replication, there can only be a single destination at this point in time.

    And how about replicate the 'secondary' to the offsite location?

    You can not do this either.
    Only Source volumes can be replicated and iSCSI must use volume replication. This means only one Source, and only one Destination.

    Default multi-site replication with failover

    Dear Administrator
    about multi-site replication not possible
    did someone change with NFS Failover or V7?
