This requirement is important so that clients accessing virtual machines running on ESXi hosts on both sides are able to function smoothly upon any VMware HA triggered virtual machine restart events. Non-uniform Host Access — This type of deployment involve the hosts at either site and see the storage volumes through the same site storage cluster only. Site Recovery Manager absolutely supports the traditional active-passive DR scenario, where a production site running applications is recovered at a second site that is idle until failover is required. However, the DRS rules and virtual machine placements are not in effect. If you would like to change your preferred language or country of origin, please click here. View All Search Results.
They can be restarted at site-A. The HA heartbeats are exchanged through the datastore.
Implementing VMware vSphere Metro Storage Cluster (vMSC) using EMC VPLEX ()
To make this website work, we log user data and share it with processors. About project SlidePlayer Terms of Service. Inger could see that the main bottleneck was storage, and he was looking for a solution that would make it possible to finish these jobs much earlier.
These customers are leveraging Site Recovery Manager to perform these failovers. It is assumed that the ESXi boot disk is located on the internal drives specific to the hosts and not on the Distributed Virtual Volume itself.
Round-trip-time for a non-uniform host access configuration is now supported up to 10 milliseconds for VPLEX Geosynchrony 5. The preceding links were correct as of August 10, All rights reserved Confidential Overview: The data storage locations, including the boot device used by the virtual machines, must be active and accessible from ESXi hosts in both data centers.
That is a real savings of money and footprint, with much better performance than we had before.
They can be restarted at site-B. The other thing we checked was performance. The vSphere Management, vMotion, and virtual machine networks are connected using a redundant network between the two sites.
We are happy to announce sgudy the SolVe Online tool and training is now available for customers!
When a VPLEX Distributed Virtual Volume is provisioned, a per volume preferred site flag may be enabled or Distributed Virtual Volumes vlex the same preferred site settings may be placed in the same consistency group. Preferably management and vMotion traffic are on separate networks. On the preferred site, the Distributed Virtual Volumes continue to provide access.
Inger says XtremIO was the right choice. May vplx, Total Views: The non-preferred site thinks that the hosts of the preferred site are dead and tries to restart the powered-on virtual machines of the preferred site.
Their Challenges For Inger, the main storage-related challenge facing his organization was end-of-month reporting on the life insurance systems.
This diagram provides an overview: Some look at it as a data migration solution while others look at it in its true flash and glory meaning — a distributed cache that is virtualizing your underlying storage and provides an active — active site topology.
For Inger, the main storage-related challenge facing his organization was end-of-month reporting on the life insurance systems.

The path policy should be set to FIXED to avoid writes to both legs of the distributed volume by the same host.
