We performed a comparison between Dell Unity XT and IBM FlashSystem based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The most valuable feature of this solution is reliability."
"It has good, reliable, fast storage."
"The solution is scalable."
"One of the best features is the support, which is excellent."
"The most valuable feature of this solution is its ease of use."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"Technical support has been helpful and responsive."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
"Ease of use is probably number one, compared to the previous storage that we've had. Easy scalability, easy set up. Compared to everything else, the Unity is, well, you could call it child's play. As long as you know what you're doing storage-wise, Unity is really easy to use."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"This solution is easy to work with and easy to maintain."
"It has compression, which allows you to store more data than you would normally under the arrays."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."
"The ease of management and “user-friendly” management environment (GUI)."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The most valuable feature of the solution is compression."
"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"This solution is convenient, user-friendly, convenient and reliable."
"Flash disk with Easy Tier option"
"One of the valuable features is the performance, it is one of the best in the market."
"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."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"In terms of what needs improvement, the dashboard and management could be simplified."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"The software layer has to improve."
"The tool's portfolio is minimal. It is expensive."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We need better data deduplication."
"I'd like to see the product implement active replication for vehicles such as VMware."
"Its replication technology could be better."
"I would like to see more integration with other products."
"Improve the interface and provide more management capability."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"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."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"They don't offer subscription-based payments."
"In the next release having the next level of high-speed performance would be great."
"They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem."
"IBM FlashSystems is lagging in optimizing storage technologies."
"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."
"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."
"The product needs to improve their scalability."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."

As with any engineered solution, it depends on your needs.
However, the bottom line is that for their target markets Dell EMC Unity will generally have a better price at parity performance over IBM's FlashSystem.
Both are focused on All-Flash arrays and Dell EMC Unity is where I start with VMWare. If I have a dedicated IBM DB2 application, I would lean toward the IBM FlashSystem.
The problem in the VMWare environment is that IBM has done a poor job prioritizing this area and has several I/O bottlenecks and interface driver issues. I expect future resolution, but does that happen before current platforms evolve?
Depends what you're expecting. Full compatibility with VMware environment - DellEMC only, IBM FS has problems with iSCSI connections to vsphere 7.02 - it's not supported (FS5200 and vsphere 7.02 server with Intel cards - doesn't work fast (10Gbe - 300MB/s instead of 1,1-1,2 GB/s), no solution for now from IBM and VMware (08/2021). Integration - DellEMC and VMware are one company - everything goes smoothly. Space reclamation didn't work well on IBM systems when connected to vsphere (vsphere 6.5 and V7000 models). When using Microsoft virtualization - no difference - it's more complex to start system but when properly configured - it runs well (fast). But of both of them I would choose HPE systems,:-) (Nimble or Primera):-)
