L3 Storage Engineer at a consultancy with 10,001+ employees
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.

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

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."
"Data Compression: Up to 80% space reduction in the database"
"With so much technological advancement and more coming, the world is their oyster."
"High performance and ease-of-management are the most valuable features."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"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."
"It performed great originally, and when it performed great, it was awesome."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"The management is simple in Pure Storage FlashArray."
"The deduplication and compression meet all of our system requirements."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."
"Technical support is good."
"It has good stability for our company."
"The solution has probably reduced my power use substantially."
"The deduplication and compression rates are beyond impressive."
 

Cons

"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."
"In future releases, I look forward to more AI features."
"The monitoring matrix and its dashboard need work."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"The solution as it is right now is not very stable. The stability seems to have eroded."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"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."
"We haven't seen ROI."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"Regarding documentation, it would be helpful if we could have access to the root passwords for administrative tasks."
"I would like a feature to integrate with external or cloud solutions."
"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
 

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."
"It could always be lower, but it's okay."
"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."
"We do not incur additional costs beyond the licensing fee."
"We have seen a reduction in total cost of ownership."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"For us, as the customer, it reduced the price of the management."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"Pure came in at a better price point than EMC and performed better than Compellent."
