Dell EMC Unity Review

Same operating system for both file and block, it simplifies everything


What is our primary use case?

It's a tier-two storage array. The performance is okay.

How has it helped my organization?

The all-flash array and the compression ratio are benefiting us. We still have to migrate a couple of systems. We are still in the process of doing it and we'll know better afterward. But, we've seen some good improvements. For example, we put it on one of the file servers and the backup performance improved quite a lot.

What is most valuable?

It has the same operating system for both file and block, and it actually simplifies everything. It's much smaller compared to VNX.

What needs improvement?

I have just been to one of the briefing sessions, here at the Dell EMC World 2018 conference, and they released a very cool feature, Snapshot replication, which is very interesting. I'm excited about that.

What do I think about the stability of the solution?

Stability seems to be good but we had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it. We felt that this could have been avoided. It caused downtime to the host on two occasions.

What do I think about the scalability of the solution?

Scalability for the 650F is good, but I was expecting a little bit more than that.

How is customer service and technical support?

Technical support was helpful. I would have appreciated it if it were a lot faster, but we got a resolution for our issue.

Which solutions did we use previously?

We come from VNX, and we also have VMAXs.

What other advice do I have?

When selecting a vendor we look at the 

  • performance 
  • scalability
  • price.

First of all, it should meet the business requirements such as performance, and it should be compatible with all applications. Then we will look at the third factor which is the price.

Regarding advice, it depends on the size of the business. Unity, price per Gig, is actually a good system. In fact, I'm thinking of moving some of the old VMAX arrays to Unity because of the price performance per Gig. If the stability makes sense, then I'm actually going to move it.
