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.

Good support, improves performance, scales well, and boosts team efficiency
For us, in terms of what is very important, is keeping pace with the evolution of the new standards. For example, as PCI Express 4.0 becomes more ubiquitous, moving into PCI Express 5 is important. Having an architecture that can truly utilize 200-gig or maybe 400-gig networking, or having storage densities in line with what we would expect in a Gen 4, Gen 5 PCI Express, are things that as they come available, I hope that the vendor is looking at that going into the future. We need this because we're really at the point where our workloads are about to explode outwards. I would like to see the management layer improved. HyperOS 3.0 is excellent, and this is important because one of the things that we looked at in the beginning, before HyperOS 3.0 had been released, was that this is an excellent technology and it's very versatile, but it would be great if we could run certain things on this box. It would be helpful if there were more ways to consume the APIs or if there were some ways to get into the hardware, get into the functionality of the system programmatically, or have flexibility where, for example, we just need to do quick namespaces, or something similar. We don't want to deploy an entire secondary storage layer on top of this. Rather, we just want to run something quick. Having a containerized system or having some sort of first-party support for basic storage functionality, or basic extensibility would be excellent for us. In many ways, these boxes are very malleable. It's a blank slate, but having a little more in terms of, if you want more directed use of it, having some way to really get at that, would be helpful.

Quotes from Members

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

Pros

"I have seen a huge increase in speed and performance on our databases."
"Because of the encryption, we have different storage and the encryption can go over both, therefore we are NCA compliant."
"Pure Storage is extremely reliable — it's never failed."
"The mobile app is very helpful."
"The most valuable feature is how it simplifies the management of the SAN."
"We currently have four Pure Storage FlashArray boxes, and all the storage boxes are on an Evergreen subscription model where we receive the latest hardware and features without any cost in a completely non-intrusive task."
"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."
"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."
"This solution is very stable."
"If you are targeting functionality, we get the most functionality from IBM FlashSystem, and then from Pure Storage, and then from Dell EMC boxes."
"As a result of the accelerated read and write operations from disks, productivity across the enterprise has increased in daily work."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"The good thing is that it is very easy to use and anybody can allocate Launch to the systems."
"We've found the solution to be very stable so far."
"The most crucial feature of IBM FlashSystem is compression."
"It's very easy to manage."
"Pavilion provides us with DAS performance and SAN manageability at an affordable price, which has allowed us to continue a very rapid growth of our business."
"The high performance is very valuable, as well as the enterprise reliability features."
"There's lots of flexibility in how we use the resources while also maintaining a small footprint."
"This unit is so dense and the performance is so high that the advice I would give is that if performance is a critical factor for your use case, then you really ought to look at this unit."
"In summary, this is an excellent system."
"We have been able to consolidate storage into Pavilion. Pavilions are our only SANs because it is a bring your own disk solution. When new drives come out, we are able to take out half of the drives in the system, put in new drives, move our VMs over to the new drives, take the other drives out, and populate those with new drives. Then, we are suddenly twice as dense as we were before. NVMe flash is only going to get denser and cheaper so we can make use of that every couple of years by just throwing newer disks into it at a fraction of the cost of a new SAN."
 

Cons

"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"In the next release of the solution I would like to see Vormetric native block encryption."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"I feel like there is too much automation; the user doesn't have any manual input."
"The solution is not cheap."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"Events/log analysis tools."
"Our model does not support compression or deduplication."
"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."
"GUI interface should be enhanced more as there is some issues in copy services GUI interfaces should be enhanced as this will not let the customer doing wrong configurations"
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"I would like to see bigger modules."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"I would like to see the management layer improved."
"The rail system that Pavilion uses to mount up into a standard Dell or APC cabinet extends further back than normal rails, and they cover up the zero PDU slot. So, I don't like the rail system that comes with the device. That is my biggest complaint."
"In our current configuration, we can only run the line controllers in high availability, active-standby mode, whereas we would like to see active-active implemented."
 

Pricing and Cost Advice

"It is a cheaper solution."
"We purchased a license to use this solution and we pay for the storage ourselves."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"The pricing of Pure Storage FlashArray is reasonable."
"Overall the price of the solution is expensive and this includes the license."
"The tool is cost-efficient."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"The pricing is reasonable."
"They've been much more aggressive in the last five, six years than they were before that."
"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."
"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."
"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."
"This is hardware. They have a singular array that you can populate with your own disk, or you can buy the disks through them. For controllers, you pay for the components inside of the SAN, but there is only one chassis that they work with."
"The licensing fees are very reasonable."
