Quotes From Members Comparing Dell EMC Unity vs. Dell EMC XtremIO Flash

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Pros
It is easy to scale, maintain, and manage.They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use.It has saved us time when provisioning new storage, so we're trying to automate that process.Compared to our old platform, everything is more tightly integrated. I don't have to go to different sections to do something. A lot of it is wizard-driven, so it's an easy to use system.Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares.Purchasing; We worked with a sales rep to purchase our Unity.They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well.The solution is so easy to manage that I forget it is there.

The most valuable features are: complete performance and ease of use.It was very easy and straightforward to setup.It has very good performance for an application which needs lower latency and a better response, for example, in microseconds.Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs.Speed and reliability:It is great for applications like Microsoft Exchange, ERP, SQL and VDI; basically saved the VDI buy-in from users, as now performance was seamless in comparison to a physical PC.Thin storage allocationThe guaranteed sub-millisecond response time for a 4K block.

Cons
The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number.Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that.It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual.The iSCSI and the VMware integation using vSphere could be less confusing.It needs deduplication. We'd like to have the dedupe capabilities in the Unity.There are a lot of things that can be done with it. It's got Cloud IQ, but I think it's not as mature as it could be, they could make it more effective. They could make it more comparable to some of the other products out there that have cloud analytics. The amount of insight that the Unity product is able to give, at this point, is okay, but not class-leading. Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide.I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage.We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that.

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.I am not too impressed with XtremeIO because we had a major failure.The GUI could be modified more in terms of how the different components are linked to each other.Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data.I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks.Get rid of the Java aspect of the GUI console.Management: At the time, there was no snapshot scheduler, so I had to write XSnapCourier to address it. The sad thing is that even after the newest release, which includes a native scheduler, most customers using XSnapCourier chose to stick with it due to a more feature-rich experience.In some cases where we don’t need the flexibility of the virtualization layer, we could free up resources on the VPLEX by using the storage replication.

Pricing and Cost Advice
Go with the virtual appliance versus the hardware.Licensing is fine. We worked with a sales rep to purchase our Unity.The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense.Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government.The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose.In the SQL Server instances in our data warehouse, we immediately saw a great return on investment.Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product.The ROI is right where we need it to be. It's a reasonably priced array.

It is expensive if you need to increase scalability.With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms).It is costly but worth it.Don’t buy this array. You’re paying for loads of magic beans, since it’s mediocre at best for a platform in a rapidly growing field. Look instead at Pure Storage or something with variable block deduplication. You’ll end up spending less and getting a better product with actual support.XtremIO is pretty straightforward about pricing. However, you need to look at your data so you can estimate, with the advice of DEL EMC, what data reduction ratio you will reach. In our case, a 3:1 reduction ration gave us a positive case compared to other storage arrays.It is great when a product can deliver high-end performance capabilities while offering a very competitive price point.It's not cheap, but it absolutely gets the job done. I don't have any real comment regarding licensing specifically.This is the best flash array on the market for high-end workloads, so expect to pay for that. But the support subscription cost is fixed for seven years, which made it easier for us to plan on the maintenance costs.
