Very easy to use in terms of administrative tasks on the GUI
Pros and Cons
- "It has very good performance for an application which needs lower latency and a better response, for example, in microseconds."
- "The GUI could be modified more in terms of how the different components are linked to each other."
How has it helped my organization?
What is most valuable?
It has very good performance for an application which needs lower latency and a better response, for example, in microseconds. It's very easy to use in terms of administrative tasks on the GUI.
What needs improvement?
At times, it's difficult to track down allocated resources as compared to other solutions, like VMAX and VNX, because it's completely software-based.
The GUI could be modified more in terms of how the different components are linked to each other.
What do I think about the stability of the solution?
Yes, we had issues with data corruption on one of the X-Bricks. The issue propagated to other X-Bricks as well.

880,435 professionals have used our research since 2012.
What do I think about the scalability of the solution?
No, in terms of scalability, we didn't encounter issues. It was very easy to add X-Bricks to the system.
How are customer service and support?
Technical support was great in terms of first response and further troubleshooting assistance.
Which solution did I use previously and why did I switch?
Yes, we were using a VMAX solution before. This product was incorporated in order to get better performance at a reduced cost for our internal customers.
How was the initial setup?
I was not involved with the initial setup phase. My role was more focused towards administrative and implementation tasks after the product was installed.
What's my experience with pricing, setup cost, and licensing?
Again, both the pricing and licensing were handled by another group. So, I can't comment on it.
Which other solutions did I evaluate?
Yes, there were multiple options evaluated and also incorporated for some percentage of the workload, like NetApp C-mode array. Specifically, XtremIO was considered for Xtreme Performance as advertised by vendors at a lower cost as compared to existing storage arrays, like VMAX and VNX.
What other advice do I have?
It's very good in terms of performance and the ease of use of its GUI. However, we had issues at the data corruption level, which resulted in multiple X-Brick failures. It's a big question for the stability and availability when we have enterprise level customers on such an Xtreme Performance array.

None of the features are valuable for us. It produced an outage and they didn't deliver on promises made.
What is most valuable?
None of the features are valuable for us. The product is poorly designed and not reliable. It performed well when it did work.
How has it helped my organization?
We have had no benefits from this product. It produced an outage and didn't deliver on promises made by the sales and engineering teams.
What needs improvement?
It needs a lot of improvement to be more like Pure Storage or Nimble AFAs.
For how long have I used the solution?
We have been using this product for a year.
What do I think about the stability of the solution?
We had stability issues. We ran out of space pretty quickly and the cost to scale did not match our needs.
What do I think about the scalability of the solution?
We had scalability issues. It does not scale in a granular manner.
How are customer service and technical support?
The technical support is horrible. It took a week for them to get back to us on what caused the outage. Also, there are too many different teams that support the product internally.
Which solution did I use previously and why did I switch?
We used EMC VMAX. We switched because EMC made it too costly to stay on VMAX and gave us discounts on XtremIO.
How was the initial setup?
The initial setup was complex. We hired someone to do it. It took them two days. Our new array was done by my team in less than two hours.
What's my experience with pricing, setup cost, and licensing?
EMC has not delivered on promises with their array. We have been with them for seven years and had five different arrays. Same story every time. Worst support in the industry.
Which other solutions did I evaluate?
We evaluated Pure Storage, Nimble, and SolidFire.
What other advice do I have?
Don't do it.

A couple of the valuable features are linear performance and deduplication.
Pros and Cons
- "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."
- "Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data."
How has it helped my organization?
It provides reliable and predictable performance with very little administration required beyond the initial setup.
What is most valuable?
- Speed – All Flash makes this array very extremely responsive to virtually all workloads, besting all of our spindle-based arrays by a large margin
- 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.
- Administration simplicity – The GUI is very intuitive and simple to use. Other vendors should take note.
- Excellent deduplication – An excellent feature and strength of the product. Inline dedupe gives you about as real-time on dedupe stats as you can get.
What needs improvement?
Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data. More and more arrays are providing the ability to replicate the data natively without the need for a secondary device to do it for them.
The EMC VNX platform is the same way. It only requires native replication via RecoverPoint. EMC’s flagship VMAX and their new Unity platform replicate natively. Even EMC's Isilon does data replication natively.
XtremeIO needs to catch up. That’s about the only Achilles heel of the product.
What do I think about the stability of the solution?
We have not had any issues with stability.
What do I think about the scalability of the solution?
We have not had any issues with scalability.
How are customer service and technical support?
Technical support is excellent.
Which solution did I use previously and why did I switch?
We did not have a previous solution.
How was the initial setup?
The setup was straightforward. Follow the installation guide and it’s a slam dunk.
Which other solutions did I evaluate?
We evaluated HPE 3PAR, Pure Storage, and EMC VNX all-flash arrays.
What other advice do I have?
We had an established EMC footprint in our data center and a good relationship. Exploring their AFA made sense. To keep things honest, we evaluated other products and conducted a PoC with other vendors.
The XtremeIO product wasn’t always the fastest, but it was absolutely linear in performance and we encountered no issues. The PoC kept pricing honest as well.

IT Manager - Storage & Backup at a healthcare company with 10,001+ employees
Its speed and reliability are valuable.
Pros and Cons
- "Speed and reliability:"
- "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."
How has it helped my organization?
Several processes that used to take several hours to complete are now taking minutes to complete.
There are advanced features we currently are not utilizing (AppSync, Snaps of Prod, etc.) but they are features we plan to deploy that would bring additional efficiencies.
What is most valuable?
Speed and reliability: This system hosts several mission-critical, latency-sensitive workloads and XtremIO has delivered on those promises.
What needs improvement?
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.
-You could not mix drive sizes
-You could not add just a single XBrick
-You had to fully populate both XBrick’s
All of this equals a very expensive\large upgrade path
However; after saying all of this, EMC announced a new generation of XTremIO (X2) which allows more granular growth, mixed drive size, etc…
(You need to purchase new hardware – I don’t believe they are adding these features to existing XTremIO Clusters.)
What do I think about the stability of the solution?
Knock on wood, we have not had any stability issues.
What do I think about the scalability of the solution?
We have not specifically had scalability problems. Upgrade paths are fixed.
Paths, capacity, and performance scale as X-Bricks are added.
How are customer service and technical support?
Technical support is excellent. This product line receives high-level support.
The only negative was enough field support during early deployments (longer lead times than average). That has since been resolved with additional training and staffing levels.
Which solution did I use previously and why did I switch?
We were using several other technologies prior to introducing XtremIO.
We switched because PoC testing proved the all-flash option to offer superior performance as compared to existing in-house technologies.
How was the initial setup?
The install and setup was very easy and straightforward. With the proper pre-planning and facility work (power, cooling, network & FC connections), we were up and operational within a few hours:
- Installed a virtual appliance to manage the clusters.
- Assigned IPs to network ports for management.
- Connected FC ports to existing SAN fabric.
- Zoned hosts to ports.
- Carved out LUNs and assigned to zoned hosts.
What's my experience with pricing, setup cost, and licensing?
At first glance, this solution is pretty expensive. However, when you factor in inline deduplication, inline compression, zero-overhead snaps, thin, etc., you find the overall cost to be inline\better than with traditional tier 1 storage subsystems.
With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms).
This makes some happy dev testers!
Which other solutions did I evaluate?
We did research several other vendors (Pure Storage, Hitachi, IBM, etc.), but we only conducted a PoC on EMC’s XtremIO.
What other advice do I have?
Download and utilize a free deduplication\compression tool to identify effective rates to determine effective capacity cost.

Dedupe, compression and high I/O are the most valuable features.
Pros and Cons
- "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."
- "Get rid of the Java aspect of the GUI console."
How has it helped my organization?
VDI is one of the top mission-critical things we offer our users. This storage runs our whole VDI environment and barely shows a blip on I/O. Previously, we had ran the VDI on non-flash storage and when Windows updates came out, we had to install them in schedule segments so as not to overload the storage. With this storage, we do them all at the same time and there is no impact to performance if 1 or 100 VMs reboot at the same time.
What is most valuable?
Dedupe, compression and high I/O are the most valuable features. 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.
What needs improvement?
Get rid of the Java aspect of the GUI console. Basically, the GUI to administrator the array uses Java as its base to run on. Java at best is buggy and prone to loading issues, so moving away from this platform would be nice.
What do I think about the stability of the solution?
We had no issues with stability.
What do I think about the scalability of the solution?
We had no issues with scalability.
How are customer service and technical support?
I would give technical support 9 out of 10. Nothing is perfect but they sure are close to it.
Which solution did I use previously and why did I switch?
We previously used deployed EMC VNX storage (and still use it for our lower performance applications) and before that, we had Dell EqualLogic. We switched to an all-flash array as we wanted high performance storage for our three most critical applications (Exchange, ERP and VDI). We wanted to do a full VDI platform for all our users and locations. We wanted the best experience for them, as any hiccup would mean a lower buy-in rate from them. This storage made that task much easier.
How was the initial setup?
We bought it through VCE, so they included setup with it. Things went smoothly. When we did receive the storage, within a day or two, we had a controller failure but since it had two controllers, there was no impact to users. Support was fantastic and got it replaced over the weekend, and we didn’t even have to do anything other than authorize them into our data center to replace the failed part.
What's my experience with pricing, setup cost, and licensing?
It is costly but worth it. If the network or infrastructure you have is always a sticking point to users or management, spending the bucks on an all-flash array can help win them over.
Which other solutions did I evaluate?
We looked at more EMC VNX storage but at that time, we were not aware of this offering. When we started doing the talks with EMC, our rep pointed at this product line and once we saw a demo, we were sold. After more research, it didn’t take us long to get the paperwork in place. We also didn’t look at other vendors, as we utilize VCE as our main infrastructure at our data center so regardless of what model or product line of EMC we bought, VCE would handle the support. This was one of the main reasons of going with VCE, so we wanted to carry it on with the new storage.
What other advice do I have?
I wish we bought double the capacity but we only had so much to spend, as I would put every application/server on this array.

Management, planning, and support are areas with room for improvement.
Pros and Cons
- "Thin storage allocation"
- "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."
How has it helped my organization?
- The increase in available I/O dramatically changed the responsiveness of our Windows environment.
- SQL server limitations of tempDB and overrun were non-existent.
What is most valuable?
- Deduplication
- High I/O capacity
- Thin storage allocation
- Snapshot cost and speed
What needs improvement?
- 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.
- Planning: The VAR we went through told us we would get something like an 8 x 1 ratio between compression and inline deduplication after migration from NetApp. For this reason, we only elected for 20 TB raw. What we actually got, however, was little over 2 to 1, which was actually worse than what NetApp afforded us.
- Support: Even though we paid for a four-hour turnaround support contract, we would have to wait up to two weeks for a response from EMC XtremIO support, because they didn’t actually have the support staff to handle new volume.
What do I think about the stability of the solution?
We have had major stability issues. Over the course of two years, three of the four storage controllers failed. It took us over two weeks to get a replacement for the first.
How are customer service and technical support?
Technical support was the worst possible. Regardless of the fact that we paid for a four-hour turnaround, we were waiting two weeks for support calls. When we did get support calls, the engineers were up to four hours late to the datacenter. After the engineers would finally show up, we would still wait weeks for parts.
Which solution did I use previously and why did I switch?
We previously used a large NetApp array, but the issue was storage density. We were at the point where we couldn’t add any further disk shelves to the controllers.
What's my experience with pricing, setup cost, and licensing?
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.
Which other solutions did I evaluate?
We were not given the opportunity to evaluate alternatives. Upper management made the decision without the input of the engineers.
What other advice do I have?
Don’t consider it. Look at a platform that has actual support. EMC is a big name, but their support model is terrible with an even worse model for implementation. For a platform you literally can’t touch without them, you’re stranded on a desert island with no help in sight.

Deduplication and compression are the most valuable features.
Pros and Cons
- "The guaranteed sub-millisecond response time for a 4K block."
- "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."
How has it helped my organization?
We use it together with VPLEX, which virtualizes the storage array with all its benefits.
This virtualization layer adds to the latency. With XtremIO behind the VPLEX, the response times are far below the response time we have on our other storage arrays, even with the SSD onboard.
What is most valuable?
The data reduction (deduplication and compression) is the most valuable feature in our business case.
We calculated a reduction ratio of 3:1 to get a positive case, and we actually reached a little bit higher (3,1:1). This makes our business case even better.
Even with this feature, the response time is far below what we received with our other storage arrays.
Another valuable feature is the guaranteed sub-millisecond response time for a 4K block.
What needs improvement?
It has no storage replication. The replication is done through the VPLEX. 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.
What do I think about the stability of the solution?
Until now, we have not encountered any issues with stability.
What do I think about the scalability of the solution?
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.
How are customer service and technical support?
Technical support is good. The installation went smoothly from DEL EMC’s site. We did not encounter real technical issues yet, but the questions we had were all answered within an acceptable time frame.
Part replacements are done transparently without any intervention from our site.
Which solution did I use previously and why did I switch?
We used HPE and EMC storage arrays, but the main reason we switched was the positive business case. We have a lot more flexibility (VPLEX), reduction of cost and floor space (XtremIO), due to deduplication and compression.
How was the initial setup?
The initial setup of the XtermIO was very straightforward in combination with VPLEX. The setup of the VPLEX was little bit more complex, but XtremIO just needed to be connected to the VPLEX.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
The XtremIO by itself without a virtualization layer has some drawbacks, like storage replication. I really would recommend them to install it in combination with a storage virtualization layer.
