Featured Reviews

Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades

The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

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.

Quotes from Members

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

Pros

"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."

"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."

"It's easy to use, and the maintenance upgrades to get free controllers work really well."

"Performance is the most valuable feature."

"I can personally state that the Pure Storage Flash Systems are the best built and Pure has the utmost professional customer care."

"The most valuable feature is it never goes down. We can expand and create volumes."

"The most valuable feature is its speed."

"As soon as we introduced our first Pure Storage FlashArray, the first benefit we saw, from our very first benchmarks, was that our production databases simply ran twice as fast with no other changes."

More Everpure FlashArray pros

"The K2 has basically removed storage as a bottleneck in our datacenter."

"Provisioning large numbers of virtual desktops has sped up considerably."

"The stability of the solution is very good."

"It has a very good duplication rate; very, very good."

"Implementation of the solution is very simple."

"It is consistently stable; haven't had a single issue with it."

"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."

"Latency is definitely the big key for us."

More Kaminario K2 [EOL] pros

"All those solutions just didn't compare with what we could do with SolidFire in terms of performance, support, product stability."

"Each time I have been in contact with technical support, it has been proactive."

"The difference between SolidFire and other storage is that it is a stand alone storage; no one has that good storage software or that scalability and performance."

"It's absolutely a consistently stable solution, with 100% up-time and no data loss at all, not even the slightest, delivering not only stability but also a lot of efficiency with the data storage."

"The initial setup was easy, very simple, and we were up and running in less than an hour after it was racked and stacked."

"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."

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

"If you're looking for an easy-to-implement solution from an all-flash perspective, really take a look at SolidFire."

More SolidFire pros

Cons

"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."

"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."

"In the next release, I would like to see file-level encryption."

"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."

"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."

"When creating a support case, visibility should be extended to others involved in assisting."

"Storage. There could be better storage."

"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."

More Everpure FlashArray cons

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

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

"Replication and de-duplication could be better."

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

"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

"There are some mid-market SMB customers that it may not fit the best for from a pricing perspective, but for the vast majority of our customers, once we aware of it and learned about the technology which it performed with, it fits a very useful metric."

"The interface look and feel could be improved."

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

More Kaminario K2 [EOL] cons

"There is room for improvement with a focus on creating a centralized storage system, functioning similar to AWS."

"However, when we wanted to change how we want to do it and basically start it over, do some hands on training with some of the architects who would be working on it, one of the issues was there wasn't an admin password at the BIOS level to restart it over."

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

"You don't have business continuity with SolidFire. I think it could be a nice feature to have in the future."

"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."

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

"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."

"The upcoming release is supposed to have much richer VMware virtual volume (VVOL) support, which is something we're very interested in."

Pricing and Cost Advice

"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."

"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."

"There are no licensing fees or other costs."

"It is a more expensive solution, but it is worth it. You are getting what you paid for."

"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."

"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."

"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

More Everpure FlashArray 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."

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

"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."

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

"The licensing is all-inclusive."

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

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

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

"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"
