EMC VPLEX CASE STUDY

Feedback Privacy Policy Feedback. This topology requires the tedious data movement process to bring systems down, reconcile, and restart them. Uniform Host Access Cross-Connect — This deployment involves establishing a front-end SAN across the two sites, so that the hosts at one site could see the storage cluster at the same site as well as the other site. When the array is recovered from the failure, the storage volume at site-B is resynchronized from site-A automatically. On the preferred site, the Distributed Virtual Volumes continue to provide access.

May 24, Total Views: Auth with social network: And we have found XtremIO to be totally reliable, with zero problems. 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. This topology requires the tedious data movement process to bring systems down, reconcile, and restart them. The same impact occurs in a uniform hosts access configuration since both sites are down.

The HA heartbeats are exchanged through the datastore. This article resolved my issue.

HA fails over these virtual machines on the other site.

For more information, see: Clal Insurance was looking for at least 3ms; they achieved 1. In a uniform hosts access configuration, the virtual machines run without any impact since the ESXi hosts at Site-A can still access the distributed volume through Site-B.

Any IP subnet used by the virtual machine that resides on it must be accessible from ESXi hosts in both data centers. This diagram provides an example: No virtual machine failovers occur. They can be restarted at site-A. Virtual machines running in preferred site are not impacted. What can we do to improve this information?

On powering on the ESXi hosts at each site, the virtual machines are restarted and resume normal operations. If you find a link is broken, provide feedback and a VMware employee will update the link.

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. For management and vMotion traffic, the ESXi hosts in both data centers must have a private network on the same IP subnet and broadcast domain. There is no down time if you configure FT on the virtual machines. In a uniform hosts access configuration, the virtual machines run without any impact since the ESXi host can still access the distributed volume through the preferred site.

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. This article did not resolve my issue.
