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.

Has supported long-term data protection and backup while requiring better part availability and pricing options
For monitoring purposes, we normally use flash access storage exclusively. We utilize a hybrid system because we need performance, combining NL-SAS for the volume and SAS flash to use as a fast cache system that provides more IOPS. We normally implement RAID 10, which we prefer over RAID 6's n plus 2 combinations. We utilize it for data redundancy, even with write intensity on. Regarding the unified storage architecture for NetApp FAS Series, we normally opt for exclusivity unless budget constraints exist. Our IOPS are very high, reaching somewhere about 50k to 150k or 1.150k. The high performance ensures minimal latency. An advantage we've seen with NetApp FAS Series is that snapshots provide very rapid backup and fast recovery. We basically use snapshots for data protection as first-level protection, with deduplication between the two storages serving as second-level protection.

Quotes from Members

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

Pros

"The availability and ease of use are the big features."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"I can personally state that the Pure Storage Flash Systems are the best built and Pure has the utmost professional customer care."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"Its ease of use is a very big thing for our customers; it's easy to set up and easy to maintain, and the support is automated, which is very good."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"Using this solution has improved our consolidation ratio and it saves us a lot of space."
"The most valuable feature is its speed."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Its initial setup process is easy."
"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 highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"The solution's initial setup process is easy."
"Lenovo ThinkSystem DE Series is simple to use"
"The solution is very easy to set up."
"The integration with cloud environments has benefited my customers' storage strategy by providing cloud volume ONTAP."
"Using the built-in Snapshots and SnapMirror technology, we were able to have better working data protection locally and off-site."
"The replication feature protects us from data loss."
"It has been pretty stable, and when we have issues, the support has been great as well."
"It gives us the performance we need and the reliability we need to make sure that our systems have the uptime that our internal customers demand."
"The product is user-friendly and helps to evaluate the performance of each node. It ensures that if one node encounters an issue, the system can immediately redistribute the workload without interruptions. This setup provides uninterrupted operation for our systems."
"The file sharing feature is most valuable."
"Using the built-in Snapshots and SnapMirror technology, we were able to have better working data protection locally and off-site."
 

Cons

"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"I would love to see a true one click upgrade solution."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"Usually, when a part fails, we have to replace it and it takes a while."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"There could be a snapshot feature in the solution."
"The solution could be more scalable, although it suits our present needs."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The features are limited."
"One of the issues that we have had with NetApp in upgrading over the years is that migrating data from one system to another is one-way only."
"It could be more flexible in terms of configuration."
"Migration from 7-Mode to Clustered Data ONTAP need improvement. It seems NetApp didn't know how to solve the main problem of migrating data from an old OS (7-Mode ) to Clustered."
"Currently, the newest release is not HCI friendly."
"The main area for improvement for NetApp FAS Series is price. Unfortunately, in India, NetApp price clearance takes longer than EMC."
"The current snapshot technology in VMFS is to say the least very poor – best practice is to have no more than 2-3 snapshots in a chain (even though the maximum is 32) and to use no single snapshot for more than 24-72 hours – the reason is simple, storage performance will suffer if you create a snapshot on a VM."
"The biggest issue we face is parts delivery. There's no local warehouse in Myanmar, so if a customer encounters a technical problem like an IMEI issue, they have to wait a long time for replacement parts."
"There is no NetApp infrastructure set up here in Greece."
 

Pricing and Cost Advice

"We have an Evergreen Storage subscription, which I think is a great feature."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"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."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"Pricing is very competitive, and it's better than other competitors."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"The solution's price could be better."
"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."
"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."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"It is an expensive solution."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The best thing about this solution is its price, which reduces our costs."
"We have considered upgrading to an All-Flash solution but when we evaluated the cost-benefit we discovered that we don't have enough money to invest in it. To maintain the same technology with All-Flash would be too expensive for us."
"I would rate the pricing a seven out of ten, with ten being expensive. We pay a one-time purchase price."
"The pricing of NetApp FAS Series is reasonable for its performance."
"It’s difficult for us to get money, so make sure you get everything in order, because there’s no going back and saying “oh, I missed this or that”, so make sure you plan well and well in advance."
"We are on a perpetual license."
"it’s not an inexpensive solution and it may not be for the cost-sensitive customer."
"The solution is more expensive than other vendors."
"The product's pricing is reasonable."
