Quotes From Members Comparing Dell EMC XtremIO Flash vs. IBM FlashSystem

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Pros
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.

The FS900 uses custom built flash modules offering with better latency, and is also denser packed then most modular all-flash arrays using commodity SSDs.An easy interface to set up, good build quality, and easily accessible parts for hot swapping combined with sub 500 us latency under heavy load.The initial customer technical support was efficient and effective.The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range.The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer.The most valuable features are, of course, the virtualization of the storage, the performance, and the compression.The speed of the unit is its best feature. It performs very well.The speed and the ease of installation are the most valuable features.

Cons
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.

When we performed some HW fault tests under heavy load, we found that some of the parts (fan units and PSUs) should only be removed from the airflow for a short time (less than a minute) when replacing.Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR.With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage.I would like to see bigger modules.I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better.The array level RAID does not seem available.It has room for improvement in the area of stability.

Pricing and Cost Advice
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.

The total storage capacity vs price is still quite high for the IBM Flash Array.

Overview
Bring all-flash, scale-out storage to your enterprise applications with EMC XtremIO. Purpose-built for flash, XtremIO storage arrays are amazingly fast. Delivering high IOPS at less than 1 millisecond latency is just the start. EMC XtremIO helps you harness the power of flash storage by building in innovations like content-based data placement and dual-stage metadata.IBM FlashSystem products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.
