IBM FlashSystem Review

Good deduplication features and stability


What is our primary use case?

Our primary use case of this solution is deduplication.

What is most valuable?

The feature I find most valuable is the deduplication because the nature of the data that we are using in our current environment has a lot of replicated data. You tend to create a copy of the same system multiple times for different reasons. So if you use a flash system that is deduplication-enabled, you end up using less capacity. 

What needs improvement?

I would like to see an improvement in the handling of large amounts of rights. An automatic flash system that doesn't do compression or deduplication will flush through the rights directly from the host to the flash modules. It doesn't keep them in the cache. For compression and deduplication systems, they have to do compression, deduplication and the memory and cache for the controller. So they have to keep the data there otherwise you will find yourself stuck with performance issues.

For how long have I used the solution?

I've been using the solution for four years now.

What do I think about the stability of the solution?

The solution is currently hosting our core banking system and we haven't faced any stability issues, so it is very stable.

What do I think about the scalability of the solution?

I have only four boxes now, so it's not the best scalability you can get, but it is still acceptable. Since we are hosting our core banking on it, we have about 20,000 employees working on it.

How are customer service and technical support?

I will rate their technical support an eight out of ten. If you send them a question, it takes them ten days to come back to you with an answer. But besides this, we've had no other issues. 

Which solution did I use previously and why did I switch?

We use EMC devices and IBM FlashSystem concurrently, but we have a different evaluation for these products. They are not the same because our critical applications are hosted on IBM FlashSystem. The less critical applications are hosted on VMAX.

How was the initial setup?

The setup of the IBM devices is really straightforward. The actual deployment for the IBM FlashSystem took about seven hours. One of our partners was responsible for this, and we are very satisfied with his performance.

What other advice do I have?

My advice to others would be to go for the big one, the A9000. It is a little bit more expensive but it offers a better total cost of ownership.

In the next version, I would like to see external virtualization. We are currently using LVC for external virtualization, and then we are using the boxes under LVC. If IBM embeds the LVC feature inside the box, I will only need to use the box and then virtualize the smaller boxes behind it. It will simplify my issues.

I rate this solution a nine out of ten.
