Featured Reviews

Chief Technology Officer at Lambda256

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.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

A versatile storage solution suitable for various workloads in cloud environments providing scalable architecture, granular Quality of Service and consistent performance

The most significant benefit lies in its exceptional performance, driven by its Flash-based architecture. This enhances routing speed and, consequently, database performance. The provisioning process is efficient and doesn't demand higher latency, ensuring optimal data transfer performance which is particularly valuable for tasks like data mining, where quick results are essential.

Quotes from Members

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

Pros

"The most valuable feature of this solution is its ease of use."

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"I appreciate the performance."

"One of the best features is the support, which is excellent."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"Everything, especially the VMs inside, is pretty fast."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

More Pure FlashArray X NVMe pros

"The most valuable feature is definitely the always-on data deduplication."

"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."

"Implementation of the solution is very simple."

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."

"The ratio between the physical storage and the storage we use is very high."

"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."

"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."

More Kaminario K2 [EOL] pros

"The scalability and being able to implement it quickly."

"SolidFire provides seamless performance across your storage system when you need to scale up. Other storage systems do not do that."

"The most valuable feature is the performance, as well as how you manage performance on the system."

"Individual settings you can put on each individual volume, if you want to do that."

"If we get complaints about any kind of performance metric issues, whether it's storage related or something on the virtual side, we use it to pinpoint what the actual issue is."

"We can add a node, we add compute, we add storage, and we've had really good luck with that."

"It is very easy to scale up SolidFire."

"If you buy the solution for its specific purpose it will work well."

More SolidFire pros

Cons

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"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."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"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."

"I'd like to see the product implement active replication for vehicles such as VMware."

"In terms of what needs improvement, the dashboard and management could be simplified."

"The software layer has to improve."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

More Pure FlashArray X NVMe cons

"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

"I would like them to improve the look of the product’s external casing and shelves."

"The management graphical interface needs more improvement."

"I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."

"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."

"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."

"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."

"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

More Kaminario K2 [EOL] cons

"It's a very good Windows-type solution. But we do a lot of legacy systems and the like. So it's getting that incorporated into it that would help us."

"The inclusion of more protocols and interfaces would make it easier to integrate with other products."

"One of the challenges we faced while using SolidFire was that the product line that we were using in our company was discontinued."

"SolidFire could improve in terms of hardware robustness."

"They could make the mNode more user-friendly. Now you need to configure and add nodes by CLI and it’s not really easy to manage. If they created a web interface to do the management of the mNode, that would be great!."

"We have a large fiber channel infrastructure, and that's one area that we haven't seen implemented in SolidFire, its more iSCSI."

"The tool should improve its initial cost which is expensive compared to other products."

"The technical support is really bad and has to be improved."

More SolidFire cons

Pricing and Cost Advice

"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."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"Our licensing fees are $500,000+ USD."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"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."

"We pay approximately $50,000 USD per year in licensing fees."

"The product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"Kaminario is very competitive on price. They also have a pay per TB model."

"The licensing is all-inclusive."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"On a scale where one is a high price and ten is a low price, I rate the solution between three and four. It is an expensive solution."

"We would probably use SolidFire more, except we're getting more bang for our buck with our purchases of ONTAP right now, and the deal we made with NetApp, so it's more of just a cost decision"

"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."

"Based on what I heard from other people, its price was on the higher side."

"The price of this solution is more expensive than others."
