You can also set replication between VNXe (1st generation, like VNXe3300, VNX3150, or others) where your VNXe is the source. The replication works well between VNX and Celerra NS480s, NS40s, NS20s or NX4s. Since we have a global presence and we are tasked to protect data from around the globe, we have enabled replication between locations. In our scenario, we only use it for disaster recovery.

The replication feature provides another functionality to protect your data. For the block, you can use LUN cloning and have the ability to present a copy of the same LUN used for production to your test environment and test applications, programs, OS, or any others without affecting your production environment. We have limited times when our checkpoints become corrupted for some reason (reaching a maximum size of a file system 16TB) or another but the majority of the time works according to plan. It is a risk to put the backups and production data in the same array, but we understood it and went with it. We use the checkpoints as backups for our file system instead of having them in a separate product. It also provides a command line interface that you can use to connect using Putty.exe but some of the commands that you can execute through the GUI are not available in CLI, or at least that is what EMC support has told me.Īnother great feature is the checkpoints for file systems. The process of extending the size of either an LUN or a file system is very intuitive. It allows you to administer both the block and file in a single pane. Through a single interface called UNISPHERE™, we manage the array. The ability to run a unified array is a great advantage when the company economics would not allow you to have separate arrays for your servers and another one for your file systems and use the unit as NAS. The VNX 5700 provides a large number of features including the ability to work for both file and block as a unified array.
