Featured Reviews

Technical Lead at Wipro Limited

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.

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

"The performance of the storage is just unbelievable."

"The solution is stable with low vulnerabilities."

"The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."

"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."

"It is simple, powerful, and a beautiful solution."

"You can get your storage access within two minutes, which is great, because it is a lot quicker for our team to get the servers up and running."

"Image backups of our production servers that used to take hours now take minutes."

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

More Kaminario K2 [EOL] pros

"The square footage for doing development is at a premium when dealing with government networks. To be able to put a lot of IOPS in a lot of high-speed performing drives in a very small location which requires very little HVAC with very little power, it is very valuable to us."

"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 scalability and being able to implement it quickly."

"To my mind, it offers a unique combination that isn't easily matched in the marketplace."

More SolidFire pros

Cons

"Currently, the solution fails to support file screening."

"The interface lacks the same level of control as some other arrays I've used."

"I think replication is one area that still needs improvement."

"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."

"It was not proactive communication."

"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."

"I would like a feature to integrate with external or cloud solutions."

"It was a little costly."

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."

"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."

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

"I'd give it a perfect rating if I could push it to 300,000 IOPS like they promote; we just haven't been able to push that many IOPS out of our system."

"The interface look and feel could be improved."

"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."

"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."

More Kaminario K2 [EOL] cons

"That's one of disadvantages, the actual cost."

"When you set up the nodes, we have to serial into each one of these nodes to configure the IP ranges. It's still very easy, but it's time consuming."

"The level of monitoring could be better."

"They could do a file-based NAS: SolidFire NAS-based. It's probably not its niche, but that is our direction, not to use block, and it's block. Solid state block is what it is."

"SolidFire could improve in terms of hardware robustness."

"It would be good to provide administrative access at the root level to be able to do things with the system, if need be."

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

"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."

Pricing and Cost Advice

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"Pure Storage FlashArray is expensive."

"It is a cheaper solution."

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

"We feel that the pricing is fair and the licensing process was easy for both."

"The pricing is reasonable."

"You get what you pay for. It is expensive, but it really works."

"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."

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

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

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

"The licensing is all-inclusive."

"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."
