Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Improves cost efficiency and significantly while boosting workload performance
We have realized several benefits from using Dell PowerStore; we migrated to the current Dell PowerStore models from tiered storage, and now we're using all flash. The dedupe and compression has been a big benefit for us versus the old storage that it was running, and we've seen the performance of all flash for our storage services. My company finds particular features within Dell PowerStore valuable, primarily the cost benefits for the performance that we get out of the platform. We've definitely seen the benefit on that side of it, including the cost per terabyte, and the support from Dell has been excellent as well. We haven't had any issues with it, so it's been very reliable as a platform for us. The performance metrics I use to measure success with Dell PowerStore are all IOPS and throughput. We are not using it with AI workloads on Dell PowerStore, so it's primarily just customers running IaaS, however, it is important that it's reliable and performs well, and we get that from Dell PowerStore. Dell PowerStore has supported growth and operational success for my business; a key driver at the moment is consolidation, and the dedupe and compression ratios allow us to standardize on a single platform. This has helped improve our operational metrics and overall operations, as we now have only one vendor to support and one set of storage arrays to manage. We have a very clear path into support and escalation if there is an issue, and we are not dealing with multiple vendors.

Gives us the foundation to grow efficiently
We're a manufacturer. All of our ERP software is dependent upon fast performance and connection to this hardware. So when there was an issue years ago when something was wrong or slow, that prompted us to say, "Can we check storage? Can we check the network?" Ever since we've gone up to all-flash FAS systems, there's never any questions about performance when it comes to storage. There's been a huge leap from spinning disks to SSDs. I'm hoping with the next update, we'll go to NVMe and we'll have similar experiences. Last year, we refreshed the SAN at our headquarters. We signed a Keystone agreement with the ability to pay for storage as a service at an excellent price point yet still have the hardware on-prem. I manage the hardware, and, for me, it's the best of both worlds. We've just come up with a situation where, finally, after some time, we're going to need to buy some additional storage. In previous situations like this, it usually meant the purchase of an additional shelf at a large price. Now we have Keystone, and we're locked in at that price per tebibyte. We just have to say that we want to add 25 tebibytes and they take care of it. It's worked out really well. We work ISO 27001 certified. Since I manage the enterprise storage, we use SnapMirror, and we're currently using Veeam for backups. Thanks to what this tool provides, we are able to get through that portion of our certification without a problem. No changes, no rectifying. It's very slick. Our company's goals include maintaining a level of consistency. We're never going to be on the bleeding edge. We're never going to have the super fastest abilities. We want something that works, is easier for us to manage, and has a better growth path. For us, in the past, in the need for additional disk space, if we didn't do the sizing right in the first place, buying additional disks was incredibly expensive. Now, with Keystone, that's no longer an issue, and that's what we like.

Quotes from Members

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

Pros

"Technical support has been helpful and responsive."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"It has benefited my organization because it has reduced time to insights."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Overall stability is very good. It is a very stable solution."
"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."
"The solution is stable."
"The most valuable features are the three-to-one data reduction and the ability to scale out and up."
"The most valuable feature of Dell PowerStore is its easy-to-use feature, specifically the simplicity."
"The PowerStore's compression ratio is even higher than the Unity system."
"Overall, Dell PowerStore is very competitive in the market and able to beat the competition."
"The stability has been excellent."
"Overall, I rate Dell PowerStore a ten out of ten."
"The features of Dell PowerStore that I appreciate the most are that it just works; it's tried and true and amazing, and we never have to worry about it."
"The amazing thing is that whenever we have come up with an issue where we need to get something done, and it wasn't necessarily available, they could do things for us, usually within the next revision of the software."
"NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."
"We've reduced downtime. Without all of NetApp's benefits, we would have had to reconfigure parts of storage that would have required downtime. We have dramatically reduced our downtime through successive generations of NetApp, allowing us to get Five 9s availability."
"NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive."
"NetApp helps us get the fastest output."
"MetroCluster is the best product on the market. It synchronizes the storage. NetApp's update packages are a huge advantage because the firmware and server updates are in one package."
"NetApp support is fantastic."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
 

Cons

"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."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"There is room for improvement in the pricing of the product."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"We need better data deduplication."
"The only thing is that with PowerStore, we don't have a solution for the file object."
"From our region perspective, it would be beneficial to have support with local languages for Dell PowerStore. However, English is acceptable for us as it serves our needs."
"When we go to buy or populate more drives in the storage array, they're so expensive. If they could lower the cost for components, we would definitely expand them more and be more inclined to buy more storage units, but it's currently a price crunch for us."
"The management UI is pretty decent and gets the job done, but the upgrade process is challenging."
"There is an issue with Dell PowerStore related to future expansions which are software-related."
"Dell PowerStore has just caught up to some of the competition by introducing METRO nodes a few months ago while the competition has had the feature for years."
"There are certain shortcomings with the technical support team of Dell PowerStore, where improvements are required."
"We would consider this solution if the pricing is competitive with other options, as it offers a very good solution. However, the current price is slightly higher than the competition."
"We have several problems with the limitations of NetApp systems in terms of volume shares. We have a brick in a 700 or a controller, and we sometimes make small volumes, but Kubernetes container volumes don't allow us."
"I really don't have a lot of complaints. In the past, there were issues, however, they've really done a great job of reaching out."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
"It would be helpful if our partner organized a yearly session with my team to discuss the new feature sets on our current solutions and other ways NetApp can help us. Perhaps we are missing some information to help us make the right decision."
"The solution's ransomware protection could be improved."
"NetApp is shifting to the cloud and adopting AI, but it is not improving its core technology to deliver faster storage. We're still waiting to see if it improves speed with solutions like the 90 series."
"Pricing could always be lower."
 

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."
"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"Our licensing fees are $500,000+ USD."
"The product is expensive."
"The licensing is on a yearly basis."
"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."
"It is expensive compared to one of its competitors."
"Pricing depends on the model and negotiation. Sometimes we manage to get good discounts, sometimes not."
"Licensing is very simple. Everything is included in the basic license. There are no concerns about having to pay to add a feature. Everything is there."
"It is very expensive though when you get to this point of using the 3000 with a client. They will start to think about using another vendor. There are a lot of solutions similar to PowerStore in regards to networking capacity and their prices are very cheap compared to PowerStore."
"The solution is expensive."
"In terms of licensing, my organization has Dell Technologies End User License Agreement (EULA), but I don't know exactly how it works, though it is a big bundle of licenses for Dell Data Domain, Dell EMC Unity XT, Dell PowerStore, Dell ECS, and all such kinds of storage arrays."
"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."
"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."
