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.

Good price-performance ratio, provides simplified provisioning and management
We use this solution for provisioning and management The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption. The exterior display needs to be improved. Sorry, I like the blue lights the competition has, but maybe we can see green led lights…

The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

Quotes from Members

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

Pros

"The solution has probably reduced my power use substantially."
"The predictive performance analytics are good."
"Technical support has been amazing."
"Pure Storage is extremely reliable — it's never failed."
"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."
"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"The performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."
"The zero latency and high IOPS utilization we observe with it are significantly better than other storage solutions."
"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."
"This solution had the best cost and it was easy to work with the Vendor."
"The performance of the solution is noteworthy."
"The most valuable features of IBM FlashSystem are performance and security."
"IBM FlashSystem is flexible, quick, and has a solid design."
"They have a virtualization feature and, even if you do not want to buy that feature, you can have it as a trial for two to three months. If you have another brand of storage from another company, you can use this tool to transfer all your data from the old system to the new Storwize system, which really shortens the migration time."
"The ease of use of the system: If you have a small storage team, then this is the platform for you, because it is really easy to manage, really easy to use, and it does not take a lot of training."
"It's one of the first, fully software-defined solutions on the market available."
"The installation and service was very good."
"If you are targeting functionality, we get the most functionality from IBM FlashSystem, and then from Pure Storage, and then from Dell EMC boxes."
 

Cons

"It falls far short of protocol support."
"The initial setup of the product is complex."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"It can go down from time to time, but it's been pretty solid so far."
"Larger capacity and more storage ports would be the two things I'd like to see."
"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."
"Enhanced documentation and beginner-friendly guidelines would benefit users with less configuration experience."
"The exterior display needs to be improved."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight. Customers are uncomfortable with remote access, which affects automated remote support."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"The problem is that if the buffer is not configured correctly this increases the latency because of this delay and the retransmit."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."
"The pricing needs to be more competitive."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
 

Pricing and Cost Advice

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"Pricing is moderate. It is neither cheap nor expensive."
"Cost-wise, it's been very effective."
"There are no licensing fees or other costs."
"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."
"The price is very reasonable when compared to other solutions."
"This solution has a good price-performance ratio."
"The pricing is competitive in our country."
"We have no issues with the price as it is very competitive."
"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."
"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."
"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."
"The price is a little bit high so is rated a six out of ten."
"Our customers would like IMB FlashSystem to be less expensive."
"I find the pricing of the solution to be very reasonable."
