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

"When we needed to replace the other arrays, we went straight to Pure and life-cycled them into Pure in every segment we have."
"It's extremely stable and has good performance."
"The most valuable feature is its data reduction."
"Their REST API is wonderful, well-documented, and easy to use."
"The experience has been very good so far for the company."
"I can personally state that the Pure Storage Flash Systems are the best built and Pure has the utmost professional customer care."
"The money I saved by not renewing maintenance on the Dell EMC devices paid for the Pure Storage devices."
"We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."
"The solution has improved our organization by speeding up our operations and increasing the scale of operations (growth capacity)."
"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."
"Huawei OceanStor is a good product. Its interface is very simple. The complexities we encounter with recovery points are gone. We just attach to remote storage, click the application, and it starts."
"OceanStor is the best Huawei product for the data center."
"We deployed Huawei OceanStor because we had some problems increasing the number of users on our database and were suffering from slowness and downtime, and after implementing All-Flash now most of our data-intensive transactions are sitting under All-Flash and we've gotten quite a good response from our users."
"We would buy the solution again without any hesitation."
"The support is excellent."
"There is a 50% code reduction."
"Provisioning large numbers of virtual desktops has sped up considerably."
"Inline compression"
"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."
"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."
"The stability of the solution is very good."
"Latency is definitely the big key for us."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"Image backups of our production servers that used to take hours now take minutes."
 

Cons

"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"In some cases, we get into very in-depth conversations around the movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"One improvement area is the eradication time delay."
"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."
"I find the pricing of Everpure FlashArray to be quite high compared to other storage solutions; however, the reliability and features are commendable."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"There are many features which need to be added, particularly on the replication side."
"A concern with OceanStor is pricing. However, apart from that, there are no significant limitations or technical issues."
"Could have a more stable, lighter Metro and better logging system."
"Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore."
"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 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."
"Technical support is okay. However, sometimes within the support system, they provide some sort of canned automatic reply to the customer instead of setting up communication with the customers."
"Huawei OceanStor should work on its saturation level and should be able to take up more load. It should give the same performance that it gives at 20 or 30 percent load for 80 percent as well."
"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"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."
"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."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"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 them to come down in price."
"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."
 

Pricing and Cost Advice

"We have seen a reduction in total cost of ownership."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"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."
"There are no licensing fees aside from the support."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"Our costs are around $100,000."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"Huawei OceanStor is priced very well but is a bit complicated."
"Huawei's prices are very good compared to those of its competitors."
"It's roughly affordable."
"We pay a monthly licensing fee for this solution. The price could be less expensive."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"Huawei OceanStor is a cost-effective storage solution."
"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."
"Overall, the solution's pricing was cheaper."
"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."
"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 "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."
