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.

Offers flexibility and top-notch technology
You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"The money I saved by not renewing maintenance on the Dell EMC devices paid for the Pure Storage devices."
"It simplifies the overall management. We don't have to worry about storage anymore."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"We were actually able to do multiple upgrades, including head upgrades and moving between the platforms, M20 and M50, over the years. We have never once lost a ping and have never had an outage due to an OS upgrade or a complete head upgrade."
"After switching to Everpure FlashArray, we saw significant results, as whatever hardware we used before is now compressed to 80%, maximizing space utilization in a single system."
"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."
"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"From the performance that I've seen, the simplicity of how to use it, the responsiveness, and customer experience, it is one of the best companies that I have worked with so far."
"It is easy to implement or install the tool."
"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"Pricing is very fair. It's competitively priced."
"Huawei OceanStor offers good IOPS and is reliable and energy-efficient."
"The solution is scalable."
"Generally stable with good technical support."
"Huawei OceanStor utilizes a proprietary technology known as RAID 2.0. This technology sets it apart from conventional storage solutions. RAID 2.0 offers advantages over traditional configurations. OceanStor's user interface is very simple and easy to use, featuring a graphical interface that enables quick and error-free setup of the storage system. This interface ensures that users can configure the storage efficiently and without mistakes."
"Rapid deployment, easy integration management and cloning of areas."
"The product's initial setup phase can be managed easily and completed in 20 to 30 minutes. It is one of the fastest storage tools that you can implement."
"I would have to say performance at this point, because the application it is based on is so diverse."
"The most valuable feature for us is the ability to move the workload between peers, and it also has a huge advantage of helping us cut down on power consumption."
"The initial setup is pretty straightforward."
"Its performance is most valuable. This solution is much faster than other as well as older storage solutions. The performance of the system is very good. We are getting 50 times better experience than the older storages. We are using AFF 300. It also has native cloud integration and most of the features."
"This storage solution is both stable and scalable, and it works for our needs."
"Being able to partition different virtual volumes of storage is really valuable for us."
 

Cons

"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."
"When creating a support case, visibility should be extended to others involved in assisting."
"We have not had a good experience with the IBM device."
"I would like to see data tiering to AWS."
"Pure Storage FlashArray has not helped decrease the total cost of ownership."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity. The data store ran out of space, and Huawei had to send a new unit."
"Customer support is very good but if you want support and you don't have SNS switches as well, the complete solution is not there."
"The energy could be better."
"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 GUI is the only thing I would like to see improved, and the user interface is not so user friendly."
"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 solution could improve by having better integration."
"The solution’s reporting could be improved."
"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."
"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."
"There could be an improvement when it comes to SLA support, it could be faster."
"Better integration with other brands is important so we would like to see it easier to integrate."
"There could be better integration with some of our Cisco products."
"Things like the FlexClones, SnapVault, SnapMirror, all of that. Some of it's available on the EF series, but we like what we have in the FAS system."
"This solution is not available to many users because the cost is very expensive."
"I’d like to see bigger, faster, better hardware, of course. I think that is the way the hardware is trending anyway; bigger, faster CPU, better software, fewer bugs, all that stuff. T"
 

Pricing and Cost Advice

"The price of Pure Storage FlashArray is expensive."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"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."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"Pure Storage FlashArray's pricing is very competitive."
"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."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"It's roughly affordable."
"The price of the license is quite low, so it's not something special or expensive."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"Overall, the solution's pricing was cheaper."
"Pricing is very fair."
"Huawei OceanStor is priced very well but is a bit complicated."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"The product is cheap."
"It's a way to get relatively low-cost, very high-performance, low-latency block storage as a point solution."
"This solution is not available to many users because the cost is very expensive."
"Adding more capacity will increase the cost."
"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."
"The price point for EF is considerably lower than the alternatives."
"Its cost-effectiveness is a major selling point. Compared to other storage vendors, the EF-Series offers excellent value for its price. It's truly a leading product in the industry."
"The pricing of this solution is competitive with other vendors here in Egypt."
"Most of my customers pay for the license on a yearly basis. It can be expensive depending on the capacity number."
