Eugene Hemphill

Sales Manager at Multicomputos PR

Helps to save money and resources with the data compression feature

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. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

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

"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."

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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"It has benefited my organization because it has reduced time to insights."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

More Pure FlashArray X NVMe pros

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

"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."

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

"Latency is definitely the big key for us."

"Logic/software management"

"Implementation of the solution is very simple."

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

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

More Kaminario K2 [EOL] pros

"The quality of service for minimum iOS, to maximum iOS in a multi-terminal environment is very powerful. The SQL service feature is the best part of SolidFire."

"SolidFire has seamless performance for the nodes and extensions. I also like the tool’s scalability. The product’s performance does not get affected when we scale either up or down. This is not the case with other products."

"Being able to provide quality of service as promised."

"Greater IOPS, speed, it's all-flash. So seeing that everything is going to all-flash, all SSDs, SolidFire fits right in there with the emerging trend in IT."

"The dashboard is such that you don't need to be a storage expert to administer it."

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

"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."

"The simplicity of it."

More SolidFire pros

Cons

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"The tool's portfolio is minimal. It is expensive."

"We need better data deduplication."

"It is on the expensive side."

"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."

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

"Adding some functions to the product would be beneficial."

More Pure FlashArray X NVMe cons

"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."

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

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

"The interface look and feel could be improved."

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

"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."

"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."

"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."

More Kaminario K2 [EOL] cons

"We had some false positives, power supplies failing, and that's really been about it. We had a couple of glitches during some upgrade processes but nothing that was really concerning to us."

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

"SolidFire could improve in terms of hardware robustness."

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

"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."

"I think there is room for improvement needed with its storage capability. A bigger node is needed."

"Though it is a stable solution, its users may face some security issues at times...The security provided by the solution is one area that can be improved."

"For example, the ease of use with the reporting. Right now it's not impossible, but you have to know Sequel. It's a little time consuming to get those customized reports in there."

More SolidFire cons

Pricing and Cost Advice

"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."

"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."

"As far as the licensing costs, everything is included in the license."

"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."

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

"Given its price, Pure is not the first option."

"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."

More Pure FlashArray X NVMe pricing and cost advice

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

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

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

"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."

"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."

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

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

"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"

"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."
