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.

Offers high performance and dependable support for fast storage needs
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.

Technical Head with 51-200 employees
Has a fantastic feature-set and works well with workflow solutions
I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

Quotes from Members

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

Pros

"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."
"The most valuable feature is how it simplifies the management of the SAN."
"Very efficient storage"
"There is no comparison performance-wise."
"Pure support is very proactive, they monitor our infrastructure in real-time, so they respond before we even open a ticket."
"The solution offers amazing performance."
"It's extremely stable and has good performance."
"IBM FlashSystem provides a very good value."
"The most valuable features are deduplication and compression."
"I would advise colleagues to use FlashSystems."
"The speed of the unit is its best feature. It performs very well."
"We are a 100% satisfied with the stability of the solution."
"For me and for the operations team, the ease-of-use of the GUI is the most valuable feature."
"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 benefit of the product is the ease-of-management; it has significantly reduced the IT operation costs to our organization."
"It's actually shaking hands with the workflow solutions much better than any other storage."
"I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution."
 

Cons

"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"More cloud connectivity would enhance the solution."
"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"Currently, the solution fails to support file screening."
"I would like to see them develop the ability to integrate with more AWS services."
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"Deduplication feature is not mature and it is significantly increasing the latency."
"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."
"This is an expensive product and if the price were reduced it would be better."
"The stability of the solution isn't great; we have had a lot of issues with discs over the years."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"There's always room for improvement. Adding deduplication would allow us to get more bang for our buck, basically."
"The problem is that if the buffer is not configured correctly this increases the latency because of this delay and the retransmit."
"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."
"Technical support, as a whole Oracle organization is very process-oriented. So sometimes it doesn't allow you to understand the customer's specific requirements because they have their own parts, practices, and policies."
 

Pricing and Cost Advice

"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."
"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."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"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."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"The price was more favorable than Dell EMC."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"The price of Pure Storage FlashArray is expensive."
"I price of IBM FlashSystem is reasonable and competitive."
"The tool is cost-efficient."
"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"This is an expensive product and if the price were reduced it would be better."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"The solution requires a license and could be less expensive."
"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."
"The price is a little bit high so is rated a six out of ten."
