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.

Reliable solution offers good IOPS and energy efficiency
Huawei OceanStor is mainly used as a SAN in our organization's data management process Huawei OceanStor offers good IOPS and is reliable and energy-efficient. It provides a decent device for data scalability. Based on what we were quoted, the stated capacity was not a true reflection of the…

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, I am sure that Everpure FlashArray is the best option on the market."
"Now, with Pure Storage, we have totally eliminated that problem."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"The most valuable feature is its upgradeability."
"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."
"Pure Storage FlashArray has helped us decrease the storage footprint in a significant way; the dedupe and compression that they have is really good, and we're getting about four to ten in the deduplication and compression."
"The sales and executive support have been outstanding compared to the rest of the market... My upgrade paths have been simple on the Pure... It's a lot simpler to implement and a lot simpler to manage."
"All updates, upgrades, and hardware work are all performed on-line with no impact."
"The technology seems to be good, especially the performance on their all-flash storage."
"OceanStor brings to us the best performance as storage for our virtualization cluster, allowing a better performance in the apps that need to manipulate a huge amount of data."
"The most valuable feature is the availability."
"The solution's support is very helpful and responsive."
"Huawei OceanStor is easy to manage."
"It is a highly available product."
"The solution is easy to scale as needed."
"The most valuable feature is the flexibility in the rail, as it is hybrid storage and can be used for many different use cases, depending on what our customer requests."
"Logic/software management"
"The speed and, for us in particular in what we're doing, the data de-duplication."
"So coupled with the simplicity, performance, and just absolute ease of use of the management of it, I don't know why anyone wouldn't buy it."
"Provisioning large numbers of virtual desktops has sped up considerably."
"Latency is definitely the big key for us."
"I think this product hits all the big features of all the SANs that are out there, all the storage vendors that are out there and more."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"Rocketing IOPS results in performance we don't have to fixate on, so we can instead focus efforts on other layers in the stack, knowing that our SAN layer is lightning fast, with capacity to spare."
 

Cons

"I have been primarily working with storage and have not fully explored other areas, but there is some room for improvement when it comes to performance reporting."
"I would like to see them lower the costs."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"The main disadvantage of Pure Storage FlashArray is the price."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"The technical support has been a let down for us. It's something the company has to work on. We haven't been satisfied with their level of service."
"The energy could be better."
"The price could be better. It's not good for the Brazilian market."
"The upgrading process needs improvement. Deploy it and notify the customers when new versions and stuff comes out. I don't think they're doing that well."
"The duration of the built-in snapshot technology must be improved."
"CFS integration is one area where OceanStor has some room for improvement. The CFS on OceanStor is dedicated, so it's not integrated with the existing active directory domain."
"I would like to see more iterations and direct integration with other solutions."
"Huawei is not that cheap."
"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 LDAP for the management panel; I've been notified they might be currently working on it."
"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."
"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 love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."
"What I think would be a great idea for Kaminario is more visibility outside the US, when my customers start talking about AFA I notice they almost never talk about Kaminario, mainly because they just don’t know about them, and there are no local sales team to tell them about the Kaminario offering."
"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'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."
 

Pricing and Cost Advice

"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"There are no licensing fees aside from the support."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"I would rate it a seven out of ten for pricing. It could be improved."
"We have an Evergreen Storage subscription, which I think is a great feature."
"The pricing is very attractive and it delivers performance for the money."
"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."
"The tool's pricing is competitive and affordable. It has the best possible pricing that we can get from Huawei. The prices are fixed and there are no additional costs."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"It's roughly affordable."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"The price of the license is quite low, so it's not something special or expensive."
"This product value matches its price."
"The licensing is all-inclusive."
"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."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"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."
