Featured Reviews

Jaehoon Oh

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 features of this solution are its ease of use and performance."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

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

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"The solution uses newer technology for deduplication and compression."

"The high availability of the product is the most valuable feature."

More Pure FlashArray X NVMe pros

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

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

"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."

"Logic/software management"

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

"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."

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

"The GUI is very straightforward and easy to use."

More Kaminario K2 [EOL] pros

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

"We can just buy them, scale them as we need on demand, and we don't have to spend so many front end cycles on designing the architecture."

"It is very easy to scale up SolidFire."

"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."

"The most valuable feature of this solution is its scalability."

"SolidFire is one of the products that does have great APIs right out-of-the-box. It works great. The tools and the other stuff seem to work a little better right out-of-the-box than the ONTAP stuff does, C-Mode."

"Stability-wise, I rate the solution a ten out of ten."

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

More SolidFire pros

Cons

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

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"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."

"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."

"I would like to see replication and DR features in the next release of this solution."

More Pure FlashArray X NVMe cons

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

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

"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."

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

"The front panel of the drive shelf doesn't always seat firmly."

"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 interface look and feel could be improved."

More Kaminario K2 [EOL] cons

"SolidFire could improve in terms of hardware robustness."

"I would like to see integration with the cloud, number one. Being able to spin SolidFire in the cloud."

"A little better segregation of the multi-tenancy. Right now, it's just VLAN-specific, that's all you can do."

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

"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."

"SolidFire should start from two nodes instead of the four nodes. That's the only thing. In a lot of solutions, we have to use four nodes, that's the better thing. But as a starting point, two is better. That's why their starting point is expensive."

"So feature-wise, I would say more reporting tools that could be merged into it."

"This solution would be improved if it were made to be more compatible with other products."

More SolidFire cons

Pricing and Cost Advice

"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 licensing is on a yearly basis."

"The support cost per array is about $20,000 a year for 24/7 support."

"The product is expensive."

"With VMware, we pay $300,000 annually."

"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."

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

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

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

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

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

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

"The licensing is all-inclusive."

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

"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."

"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."

"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."
