Dell XtremIO is highly scalable and I would rate it a ten out of ten. My company has 2000 users for the product. We use the solution 24/7 since the last seven years. 

We have not specifically had scalability problems. Upgrade paths are fixed.

Paths, capacity, and performance scale as X-Bricks are added.

Scalability has an upper limit, so it's difficult to scale to a certain extent, or to an enterprise, level, but it simply runs out. There is a limit to how far you can go.

We have 20,000 users with varied workloads from SAP, SharePoint, and Exchange.

We intend to replace it with something else or to upgrade it as it comes to its end of life.

Dell XtremIO is highly scalable, both in terms of hardware and other aspects. It integrates well with various virtualization platforms and firmware.

The scalability is good. The option to scale out is available on XtremIO. 

Dell EMC XtremIO is scalable and it is easy to do. However, we cannot have more than four bricks.

We have approximately 10 people in the storage team who use the solution and 5,000 use the services in my organization. 

The solution is used on a daily basis. The media profiles are launched for each user and it communicates to the Dell EMC XtremIO daily.

We did have some initial issues, given the 3.x version we were on. We ended up migrating from 10TB bricks to a 20TB brick cluster when we upgraded.

We have not had any issues with scalability.

We have not had any scalability issues.

Not yet.

None that weren’t expected. This is a scale out product, not scale up or scale up and out. You can go from 1 XIO brick to 2, 2 to 4 and then 4 to 8. If you know this up front it is very easy to plan around.

There were no scalability issues.

It didn't expand to the second Node X-2, although that was a stated option.

I did not encounter any scalability issues.

We have not encountered any scalability issues.

We had no issues with scalability.

We did not immediately have scaling issues. Scaling up is, in fact, very easy. Just “buy” an X-brick of 40TB and plug it in. The system does the rebalancing automatically. Since we use a VPLEX, the scaling limitation lies with the VPLEX.

Scalability was non-hazardous and even online.

No, in terms of scalability, we didn't encounter issues. It was very easy to add X-Bricks to the system.

We had some difficulty when we tried to expand our XtremIO because it had to be done in a certain way and only EMC personnel were allowed to do it. That wasn't very flexible. But it seems to be better in the new version. Scalability is always a problem. 

XtremIO is scalable - it has expansion charges so that you can extend your storage size.

There is a limit to scalability, but we have not reached it yet.

We have not had scalability issues.

We had scalability issues. It does not scale in a granular manner.

We understand the way the platform can scale, so we scale within the parameters.

XtremIO is scalable from one engine to maybe eight engines.

The scalability is very good. We can easily upgrade and move from one generation to another.

Scability of Dell EMC XtremIO could be better.

The solution is scalable for SMBs.

Yes , I do recall we had an issue with a version of code on XtremeIO before we could Scale.

We have consumed ~756GB of disk on a 2-brick cluster and have much more than the physical capacity of the system provisioned. There have been no problems with scalability at all.

I did not encounter any issues with scalability.

We have not had scalability issues.

The scalability of this solution is good.

We have not encountered any scalability issues.

It is very expensive to scale. You have to buy an additional system to extend from one disc, for instance. It is scalable, but extremely expensive to do so.

Scaling this product is not easy.
