VNXe Replication Sessions

Jump to solution

We are currently examining adding WAN Acceleration devices between our two remote VNXe3100s.  Currently the VNXe3100s replicate CIFS shares locally, and we have an average of 200GB of changed data daily!  Current buisness needs require us to have our replicas in a remote colocation facility, thus we are looking at WAN Acceleration solutions.

My question regarding the VNXe replication sessions, are these basicly just RSYNC over SSH?  What type of protocols are used, as I would like to select a WAN optimizer which handles these protocols to get our best solution.

The VNXe uses a similar replication technology to the VNX for WAN replication.  No, it's not rsync.  You'll need to look at a WAN acceleration solution that supports Celerra/VNX IP Replicator.  Companies like Riverbed will be the focus of your research, as they're probably the most commonly-used products with Celerra Replicator.

Let us know if that helps!

Hey,

VNXe replication is Asynchronous. This means that whenever data is written to the source, it is not instantaneously replicated to the destination. Data is replicated manually or based on a certain time interval called Recovery Point Objective

(RPO).

VNXe replication provides asynchronous replication tools for creating point-in-time copies of storage resources. This is a complete copy of the data, unlike a snapshot of the data, in which only the changes to the data are saved.

There are two types of replication:

• Local – Local replication occurs within the same VNXe system.

• Remote – Remote replication occurs between a source VNXe system and a remote VNXe, VNX, or Celerra system.

Please refer to following documents:

Replication section of EMC VNXe Data Protection Overview on page 17.

Table 5 Replication limits of EMC VNXe Simple Support Matrix on page 5.
