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.

Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies
IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

Quotes from Members

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

Pros

"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"The deduplication and compression meet all of our system requirements."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"The most valuable feature is how it simplifies the management of the SAN."
"Whoever is using Pure Storage is happy with it, including the latency and everything, and we have not received any complaints related to Pure Storage throughout the four years I have worked here, which is really great."
"The stability is perfect, the reliability is 100%, and the latency is always lower than 1 millisecond."
"Pure Storage is seen as a visionary company with leading edge technology."
"We chose Pure Storage primarily because of its combination of performance and ease of use."
"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."
"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."
"It works quite well for us, and I would recommend it."
"My advice for anybody considering this solution is to go by the business needs, as opposed to just choosing the fastest solution."
"This solution has improved how our organization functions in the way that it has essentially made us not have to think about storage."
"We can capacity plan at a greater level than we used to."
"The product is scalable and easy to expand."
"We chose Pure because we like their support model and we like their performance."
"We tested a complete site loss with the initial loss of the complete data center and the system was always up."
"It is incredibly scalable; you can add more storage to it, add more file sets, and add it to more servers, making it a robust product that should be able to expand with us."
"There is nothing else that even compares to Spectrum Scale."
"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"We are using it for monitoring all of our storage."
"The most valuable feature is the ability to share files across different platforms."
"It is a scalable solution."
 

Cons

"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"One improvement area is the eradication time delay."
"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."
"There could be improvements in public cloud integration."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."
"It's on the expensive side, as expected for a niche product."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"The speed could be improved."
"The documentational aspect of FlashBlade needs improvement."
"The solution's pricing could be better."
"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"I believe there is no graphic user interface, so they should include it."
"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."
"The biggest problem is that it is not able to provide block storage."
"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
 

Pricing and Cost Advice

"All storage is expensive so any price improvement would help."
"Our costs are around $100,000."
"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."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"The solution could be cheaper."
"Pure Storage has not helped to reduce our HANA licensing costs."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"It's priced higher than the market."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"Our licensing is renewed annually."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Licensing fees are paid yearly."
"I rate the tool's pricing a seven to eight out of ten."
"Our customers have seen a reduction in TCO."
"The solution is costly but reliable."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"The licensing is based on the number of terabytes."
