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.

Replication and dashboard improve system integration efficiency
It's a good product, but the implementation with the new systems is done via the cloud dashboard from HPE. I can't activate the system without a cloud connection, which is a bit laggy if I don't have the right firewall settings, making it take longer to implement the storage. It was better with the old systems, where I could install and activate without cloud connectivity.

A solution with a simple configuration and good stability but it's quite expensive
Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

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

Pros

"I am satisfied with this solution, and we plan to keep using this solution."
"I am very satisfied with this solution and I would recommend it to others."
"Pure Storage FlashArray is a good product with minimal management requirements once set up correctly and helped reduce our storage footprint from EMC."
"For me, right now, it is the best storage solution in the market, by far."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"Cuts VM deployment down to seconds and cuts latency under MS with amazing performance and very stable operation with no worries about how much it can handle."
"The initial setup was really straight forward."
"Our clients see a reduction in total cost of ownership by around 40%."
"The solution is scalable."
"The fact that they offer free training is awesome. There are not very many vendors that do that."
"The valuable features include encryption of data, hybrid performance, firmware updates, and overall simplicity."
"They did something very well that most people fail at, they created raving fans!"
"HPE Nimble Storage is a very organized and customer-oriented tool."
"We have had no stability problems at all."
"I really like the form factor, which is nice and compact and small."
"It has increased our performance and allowed us to expand out what we can deliver."
"Inline compression"
"From my perspective, it is a huge success fulfilling everything we needed and more!"
"Improved performance by more than 50x on our application."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"Logic/software management"
"It has a very good duplication rate; very, very good."
"It is consistently stable; haven't had a single issue with it."
"Implementation of the solution is very simple."
 

Cons

"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."
"I would appreciate improvements on daily health checks."
"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"The price is too high."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"The system has dual controllers but does not have a high level of resiliency built-in."
"I'd like to see more granular quality of service rules. Currently, I think currently there's not much room for maximum IOPS, but there's not an option for minimum IOPS for a given volume."
"The scalability is average. We had a unit that wasn't that old, which we couldn't extend anymore."
"I would like to see an added feature to auto-fix, or a dynamic alerting system on storage."
"The solution is quite expensive. We can't really afford to buy a second device."
"There have been a couple of instances where we discovered previously unreported bugs."
"HPE Nimble Storage's cost is very high, making it one of its downsides."
"While we're attaching the host and creating a volume, afterward, it is a bit difficult compared to all other storage solutions."
"While the technical support isn't good every single time, for the most part, we are happy with it."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"The management graphical interface needs more improvement."
"The interface look and feel could be improved."
"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."
"The front panel of the drive shelf doesn't always seat firmly."
"Replication and de-duplication could be better."
"There are some mid-market SMB customers that it may not fit the best for from a pricing perspective, but for the vast majority of our customers, once we aware of it and learned about the technology which it performed with, it fits a very useful metric."
 

Pricing and Cost Advice

"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"The price is too high."
"Pure came in at a better price point than EMC and performed better than Compellent."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"We have seen a reduction in TCO."
"It is light years beyond anything else with the same price point."
"There are no fees for licensing. The hardware is paid for only once."
"We pay a one-time fee for terabyte licenses, and the support is paid yearly."
"It is more expensive than one of its competitors."
"There is a one-time price for hardware, and with the software support, everything is included, such as software upgrades. The licensing of the solution is included in the cost of the hardware and the support is an extra cost. We have purchased support on an annual basis, but you can purchase support up front for up to seven years. We usually buy five years and near the time of the expiry, we sometimes extend it."
"Its price is a little higher."
"If you don't go cheap, it is eventually worth it. However, the initial investment is high."
"Our hybrid solution could do with some more competitive pricing and more scaled-down deployments. Already, the smallest one is too much for us. We would flourish by having a smaller unit."
"It is cost-effective, which is important for a service provider, because you're competing with hyper-scale providers who do things at extremely large scale, who tend to kill you on price if you're not careful."
"The pricing for this product is somewhat high."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"Kaminario is very competitive on price. They also have a pay per TB model."
"The licensing is all-inclusive."
"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
