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

"The best features Everpure FlashArray offers are its ease of setup and incredible performance, which is better than most other software or hardware that we have used."
"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."
"If you're interested in using this solution, I recommend that you do the same — see if you like it."
"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."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"Technical support is very good."
"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."
"Very efficient storage"
"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."
"It is a highly available product."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"The setup and the price are the most valuable and not the features related."
"The solution has improved our organization by speeding up our operations and increasing the scale of operations (growth capacity)."
"OceanStor is the best Huawei product for the data center."
"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."
"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"Looking at what changed at Kaminario the last couple of months (and the last couple of years, for that matter) I’m certain we’ll see a lot of great innovation from Kaminario in their upcoming releases."
"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."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"Logic/software management"
"Our holdup was disk I/O, so we did a PoC with Kaminario and we reduced build times down to fifteen minutes for a full build from two hours."
 

Cons

"The integration capabilities could be improved."
"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."
"If they could make it cheaper, that would be something."
"They need to find another way of doing data protection, RAID is not working very well."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"Regarding documentation, it would be helpful if we could have access to the root passwords for administrative tasks."
"Currently, the solution fails to support file screening."
"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"The main concern is regarding the usability of the data storage."
"Configuration complexity and the tools available."
"Huawei is not that cheap."
"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."
"The administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."
"The management is not a good feature in all of Huawei products. It's not easy or simple. Huawei has some problems with management and handling storage information from one interface."
"In terms of marketing, they need to improve by putting more effort into making people aware of their products, especially in our region."
"The duration of the built-in snapshot technology must be improved."
"The front panel of the drive shelf doesn't always seat firmly."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"On the road map, 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."
"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."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"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."
"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."
 

Pricing and Cost Advice

"We feel that the pricing is fair and the licensing process was easy for both."
"Pure Storage has not helped us to reduce our licensing costs."
"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"The cost has room for improvement."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"For us, as the customer, it reduced the price of the management."
"Huawei's prices are very good compared to those of its competitors."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"It's roughly affordable."
"Its price is affordable."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"Pricing is very fair."
"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 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."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"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."
"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."
