Problem free scalability, reliable, with straightforward setup
It has good, reliable, and fast storage. We really like snapshot features and how automatable and programmable it is. It is all managed with ad sport and playbooks We have been using Pure FlashArray X NVMe for about a year now. Scalability has been great. We have run into a couple of instances…

Highly reliable, effective dynamic cache feature, and simple setup
We can use Dell EMC Unity XT for backing up SAN and NAS drives. Mainly for databases and for file servers The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now…

Quotes from Members

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

Pros

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The initial setup was extremely simple and straightforward."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The high availability of the product is the most valuable feature."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The solution is very straightforward to set up."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Technical support has been helpful and responsive."
"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."
"The most valuable feature is the fast cache with functionality rewrite."
"Dell Unity XT is user-friendly and easy to use."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"Its most valuable feature is the storage alarm."
"We are happy with the way we have Dell EMC Unity XT configured."
"Integration is easy with this product."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"The ability to create LUNs and modify them are the most valuable features of this solution."
"They have a virtualization feature and, even if you do not want to buy that feature, you can have it as a trial for two to three months. If you have another brand of storage from another company, you can use this tool to transfer all your data from the old system to the new Storwize system, which really shortens the migration time."
"The maintenance service and support from IBM is very good."
"IBM's technical support do excellent work."
"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."
"User friendly management interface."
"The compression and deduplication features are the most valuable."
"The all-flash storage has tier replication capabilities."
 

Cons

"We would like to see VNC integration or be able to use Pure Storage with VNC."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The tool's portfolio is minimal. It is expensive."
"The software layer has to improve."
"They could add more support for file storage and different types of storage."
"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"The interface can be a little challenging for someone new."
"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."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
"I would like to see more integration with other products."
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"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."
"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."
"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."
"There could be some extra features added."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."
"Sometimes the performance is effective but it gets resolved in the process."
"The ease of installation should be improved. We had issues with the configuration model."
 

Pricing and Cost Advice

"Given its price, Pure is not the first option."
"Our licensing fees are $500,000+ USD."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"The product is expensive."
"We pay approximately $50,000 USD per year in licensing fees."
"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"As far as the licensing costs, everything is included in the license."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"It scales, but then you have to buy additional stuff."
"The solution should be cheaper."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"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."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"The price is good for commercial grade storage arrays."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"You purchase it as a bundle and the price is comparable."
"I find the pricing of the solution to be very reasonable."
"I price of IBM FlashSystem is reasonable and competitive."
"They've been much more aggressive in the last five, six years than they were before that."
"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
"This is an expensive product and if the price were reduced it would be better."
"The total storage capacity vs price is still quite high for the IBM Flash Array."

EMC's Unity is not comparable to the performance of an IBM FlashSystem option, but it is fairly close in performance profile to the just released Storewize V5100 model 424. If you provide the initial amount of storage you are going to purchase and your expected capacity growth rate, plus any workoad/performance info you have on hand, and we will give you a very quick TCO and performance compar...

For a performance comparison, I use a vendor-neutral benchmark portal like Storage Performance Council: For SPC-1: a) IBM storage, including All-Flash (performance) https://spcresults.org/benchmarks/results/top10/performance/spc1/1?field_peer_review_status_target_id=48&field_sponsor_target_id=18 b) Overall top 10 SPC-1 (performance) https://spcresults.org/benchmarks/results/top10/performance/spc1/1?field_peer_review_status_target_id=48&field_sponsor_target_id=18 c) Overall top 10 SPC-1 (price/performance) https://spcresults.org/benchmarks/results/top10/price/spc1/3 For SPC-2: a) Overall top 10 SPC-2 (performance) https://spcresults.org/benchmarks/results/top10/performance/spc2/1 b) Overall top 10 SPC-2 (price/performance) https://spcresults.org/benchmarks/results/top10/price/spc2/1 I also look at specific benchmarks from the vendors: a) IBM https://www.ibm.com/developerworks/community/blogs/InsideSystemStorage/entry/spc_benchmarks_for_disk_system?lang=en b) Dell EMC https://www.dellemc.com/resources/en-us/asset/white-papers/products/storage/h15161-dell_emc_unity-performance_metrics.pdf

I am about to take delivery of a Unity 400 with SAS and have never considered an IBM hardware so i am not able to compare based on experience.
