Hi<br />
<br />
Thanks for the reply<br />

Does the VNX and SRA automatically handle all the reverse mirroring and changing the LUNs back to RW at original primary and RO at secondary?<br />
<br />

Hi All<br />
<br />
We are planning a full DR test whereby we fail our VM's over to the secondary datacenter using SRM 5.0 (this will be a full recovery, not a ring fenced test)<br />
<br />
We are unsure on how the VNX works when it comes to failing back.<br />
<br />
One of our engineers believes this will require a Full re sync from the VNX at the secondary back to the Primary before we can failback, this would require replicating 12TB of data.<br />
<br />
I would have thought if the LUN's at what was the primary site are still in tact then it would only replicate the changes that have been made since the failover.<br />
<br />
Can anyome who have ever done this with a VNX confirm, this will have a massive bearing on our DR test as we are planning on failing over, running from DR site for 4 hours then failing back, if we have to wait until a full replication from secondary to primary before we can fail back then it will take days so wont be able to do it in our weekend time window<br />
<br />
Thanks

Failback to primary datacentre when using EMC VNX 5500 and SRM

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
