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.

Quotes from Members

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

Pros

"The most valuable feature is that maintenance is free."
"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 best features of Pure Storage are their support and analytics."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"We are very happy with the data deduplication and compression ratio that we have on the platform."
"The intuitive way of managing storage is what I appreciate about Pure Storage FlashArray, along with the clever use of flash modules, and absolutely the data reduction, because they are using that in a very clever way to do compression and deduplication."
"It does everything they say it will do: It's very cost-effective compared to other big players, integrates very well with VMware, is tiny so we're saving power and space in the data center, and it's really easy for us to manage."
"Very efficient storage"
"Lenovo ThinkSystem DE Series is simple to use"
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"The solution's initial setup process is easy."

"We have been working with the solution for around a year and so far it has shown itself to be stable."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"Lenovo ThinkSystem DE Series is cost-effective; there is no license, all of the features are bundled together, and you can renew the bundle with all of the features included."
"Deduplication"
"I would absolutely encourage everybody to implement such a system because it's really, really performing so good and latencies are just excellent."
"From the automation point of view, we want zero down time for our clients with good scalability and good performance."
"Our organization has improved because this solution provides a Highly Available storage system with DR configurations, deployed across two data centers."
"I like how easy it is to discover an issue and either resolve that issue or fine-tune that app to premium support to find that resolution."

"This is a really good solution that definitely meets our needs."
"We are spending less time putting out fires, so there's a tangible benefit right there."
 

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."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"I would like to have support available in Spanish."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."

"Improvements can be made to the product's performance."
"Usually, when a part fails, we have to replace it and it takes a while."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"Technical support can be a little slow when it comes to escalating through levels of support."
"I believe that there were firmware issues. I think it was just a mismatch of things that were going on."
"They could always improve the pricing. It is relatively expensive."
"Cleaning up false positives on alerts. We get a lot of those."
"I would like to see the ability to include more applications from applications to managed storage."
"The only downside to NetApp AFF is its price."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"It has not allowed us to save money, per se; there are other solutions that are probably cheaper in the flash arena, but this was a nice transition from our NetApp 7-mode to CDOT platforms."
 

Pricing and Cost Advice

"The price is reasonable."
"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."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"The pricing of Pure Storage FlashArray is reasonable."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"The pricing is fair and low compared to other products in this category."
"It is an expensive solution."
"The best thing about this solution is its price, which reduces our costs."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"We have used the solution’s thin provisioning to add new applications without having to purchase additional storage. We use thin provisioning on all of our flash arrays at this point. It gives us the choice to be able to overprovision and take advantage of compression, compaction, and thin provisioning all at the same time. We can get more out of the purchases that we make."
"We don't like the cost. We would like to buy more."
"NetApp AFF is somewhat pricey. If they weren't as pricey, that would be a big deal for us."
"Planning of all the lifecycle storage with NetApp AFF is part of the solution. While it is not cheap, they have introduced a new series of AFF that are more affordable, providing options for more users."
"Look at the different options that NetApp offers. Look for a model and option which fits your needs correctly. Don't buy a low-end product for a high-end job."
"NetApp AFF is an expensive solution."
"Its price is quite competitive, but there is still scope for better pricing."
"Obviously depending on the price point, NetApp is obviously a little more expensive than your generic Dell SAN solution or whatever."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
