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.

Good customer service and support and suitable for large environments
It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Cloud data management that achieves cost efficiency with advanced data protection features
I am currently using Nasuni for seismic data. We have a huge data size, and we want to reduce costs. Nasuni acts as a caching solution, so we put some data into the cache, and the rest goes to the blob, which helps us save on costs. We use it for applications like Petrol and Tech Log, where 3D…

Quotes from Members

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

Pros

"Pure Storage FlashArray has helped decrease the total cost of ownership because we know what the cost is going to be every year; we don't get any hidden fees or upgrade fees, everything is included in the price."
"The administration is very easy and quite minimal, the performance is very good, the installation is pretty straightforward, and technical support is good."
"This is the best all-flash storage array on the market."
"This solution has improved my organization because it has good performance."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"Now, with Pure Storage, we have totally eliminated that problem."
"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."
"It's extremely stable and has good performance."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"Tegile All-Flash Storage Arrays deliver maximum performance, high density, compelling economics and it is ideal for latency-sensitive, business-critical workloads such as online transaction processing, real-time analytics, decision support, and data warehousing."
"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"
"We use IntelliFlash products for larger environments, like Qatar Airways."
"It has cut batch job runtime in half, so we're seeing performance improvement throughout the organization."
"After five years, the cost decreases over 30% and the performance increases over 50%."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"The initial setup is straightforward."
"The company and its technology are solid and their solution architects and support teams are EXCELLENT!!"
"The most valuable feature is the simplicity of the backup and restore functions."
"The OR and DR capabilities have been a very big help for us, reducing what used to take weeks to fix and bring back up and running for people down to a matter of minutes while keeping their experience seamless, no matter how much trouble the hardware is in at the site."
"With Nasuni, the simplicity of management is light-years ahead of our previous processes because the old backup and recovery was so slow, and we had to keep growing the SAN as the business grew."
"The solution gives us a breakdown and summary of every resource and each volume within every resource. It tells us the code within a given volume, so I can go in there and look at the size of the files that are stored there. Nasuni gives me the big picture and allows me to connect things like Power BI to any endpoint. I can take that tabular information from Nasuni and look at it in a graph."
"We like Nasuni's snapshot technology. The snapshot and recovery features are the things we use most frequently. Ideally, I would recommend NFS or CFS, which gives you more benefits for clients or anyone who wants to access FTP protocol, FTP utilities, SAN, and MSS."
"The most valuable feature is that we have redundancy in our data. It's nice to know that it is cached both locally on the filters, as well as stored on that cloud."
"The biggest and most impressive thing for us is the operational recovery (OR) and disaster recovery (DR) capabilities that Nasuni has. If a filer goes down, or an ESX server goes down, then we can quickly recover."
 

Cons

"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"The product could improve by providing the capability to support NAS storage – CIFS and NFS."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"Snapshots are not as easy to access as on a NetApp device."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"The monitoring matrix and its dashboard need work."
"In future releases, I look forward to more AI features."
"Some applications may not be suited for the Nasuni environment. You may need something with better performance. Otherwise, if you want to run daily operations or some file system, it's a good bet."
"If you need performance with less latency, you should go with another solution."
"Some of their cross-platform features are really good, but it could always use more."
"There are some issues with multiple users accessing the same file simultaneously. There would be times when the global file would lock when several people tried to access it, so that could be optimized more."
"When we first set up our bandwidth limiting, we had a few problems when it came to managing it. This is something that could be made easier; however, we were able to make the changes that we needed to for our environment."
"One thing to consider is that Nasuni will have the same limitations that a traditional file storage solution will have, although that is because they are taking the place of a traditional architectural model. For example, Office 365 supports collaboration on documents such as Excel files and Word documents, but because Nasuni is a traditional file server, in that sense, it can't make use of that functionality."
"When users from one office save their changes, their peers in another office can see the changes within minutes. Of course, this is an area for constant improvement and we hope that they can still reduce the amount of time it takes to replicate changes."
"The Nasuni file storage platform doesn't work well when there are a high number of small files. This is the case when a directory structure contains more than 10,000 or 20,000 small files, e.g., 5 KB, 10 KB, or 15 KB. When the user is accessing these files from another geographical location, they might face a slow response or timeouts when connecting to the shares, and then to the files. This is because the file size is small. There is a scope of improvement with this solution when it comes to accessing a large number of small files."
 

Pricing and Cost Advice

"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"It's a good price point and it's a solid product for the price."
"I would rate it a seven out of ten for pricing. It could be improved."
"The price, in general, is around $100,000, however, I know it costs more."
"The solution could be cheaper."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"I think we pay around 100 grand per year for three arrays or four arrays."
"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
"There are cheaper forms of storage, but Nasuni is fairly priced for the functionality it offers. I can get basic file shares provisioned in Azure and pay for the storage and the CPU. The overall cost would be much less than Nasuni, but I would need to build the management console and encryption process, so it would cost a lot to develop that kind of functionality."
"Nasuni pricing is average; it's not too high or too low."
"The pricing is fair. It's an enterprise-level solution so it's not inexpensive... The cost is pretty stable year over year."
"There are annual costs that we pay for maintaining all of the snapshot history in the cloud. That is the primary cost that we pay. We occasionally buy newer Nasuni appliances or deploy them to new offices when the need occurs. That capital equipment expenses is less than the cost of buying new file storage systems. For the most part, you are trading a CapEx cost of storage equipment for an OpEx cost for management of all the snapshot data in the cloud."
"With this solution, the license renewal is pretty swift. With the virtual appliance, you just need to take care of the OS versions and patches. In a way, we don't have to struggle much with renewals because the only thing that we need to take care of are the licenses. We renew it every three years. This aspect goes with infrastructural costs because it doesn't cost us too much to maintain the solution."
"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."
"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
"The pricing is on par with everybody else, and fair."
