Anil Rahulwar - PeerSpot reviewer
L3 Storage Engineer at Capgemini
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.
Sowjanya MV - PeerSpot reviewer
Technical Lead at Wipro Limited
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.

Quotes from Members

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

Pros

"It performed great originally, and when it performed great, it was awesome."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."
"The initial setup is straightforward."
"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."
"Data Compression: Up to 80% space reduction in the database"
"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"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"FlashArray's data reduction and NAS features are incredible. Its performance is the best I've worked with."
"It's simple, powerful, and ready to use."
"Pure Storage has been the go-to storage array for me; it's a lot smaller, easier to set up, faster to upgrade, more reliable, and the performance is very stable."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"I have never experienced an outage with the product or had any support that was below excellent."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"Pure gives us better compression, it's easier to manage, a lot less hands-on, and the biggest selling point for me was the replacement of the hardware, the controllers, without any major expense to the clinic."
"Now, with Pure Storage, we have totally eliminated that problem."
 

Cons

"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."
"In future releases, I look forward to more AI features."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"A three wave application or multi wave application synchronization would be an improvement."
"Pure Storage support could be a little better."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I would like to see them lower the costs."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"We haven't seen ROI."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
 

Pricing and Cost Advice

"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 no licensing fees or other costs."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"Pure Storage FlashArray's pricing is very competitive."
"We do not incur additional costs beyond the licensing fee."
"There are no licensing fees aside from the support."
"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."
"Pure Storage has not helped us to reduce our licensing costs."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
