IBM FlashSystem Review

Deduplication and compression afford us more space, but there is a bottleneck when adding more flash drives


What is our primary use case?

The IBM FlashSystem is the primary storage for files and data in our organization.

What is most valuable?

The most valuable features are deduplication and compression, which together, enable you to have more space.

Performance is a major advantage of this storage.

What needs improvement?

When you add more flash drives or more NVMe, that is the bottleneck or shortcoming with this type of storage. When you fill the first enclosure, you won't be able to add more NVMe until you add more SAS drives.

The security features can be improved such that the encryption does not affect performance in any way.

For how long have I used the solution?

I have been using IBM FlashSystem for about four years.

What do I think about the stability of the solution?

The stability is very good.

What do I think about the scalability of the solution?

We have approximately 1,500 people who are directly or indirectly accessing the data that is residing on this storage.

How are customer service and technical support?

The technical support is pretty good, especially the local team in Pakistan. Normally, the response time is very good.

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

This is the first flash storage system that we have used. Prior to that, we were using a hybrid Dell EMC storage.

How was the initial setup?

The initial setup is not very difficult. I would say that it is similar to the way other storage systems are set up. I believe that it took one week for our deployment, which included testing.

What about the implementation team?

We have three administrators who take care of the different applications and data that are hosted on this storage. We don't perform maintenance on a daily basis. We may extract some stats for the performance and for evaluating capability. However, when it comes to maintenance, we probably work on it once or twice a month.

What other advice do I have?

Before purchasing this product, I recommend that everyone should do a PoC because there are multiple flash drive systems now available. All storage vendors are now making flash drives because it is a new technology that replaces existing hybrid systems. I would suggest doing some analysis and some R&D because Huawei, for example, is doing well. EMC is also top of the line, with IBM. There are slight differences in features, however, so it is important to do a comparison before making any decision.

I would rate this solution a seven out of ten.

Which deployment model are you using for this solution?

On-premises

Which version of this solution are you currently using?

7000
