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.

High‑performance all‑flash storage has transformed data warehousing and reporting speed
The features of Dell PowerMax that I find most valuable so far include its all-flash capability, along with its performance, reliability, and efficiency. Additionally, it has snapshot-level features that allow me to take snapshots or backups within only a few seconds. There is no need to wait long, and unnecessary high bandwidth used for backup does not occur because I can take the whole snapshot backup within a fraction of a second. I have used the deduplication feature of Dell PowerMax. Deduplication and compression are very effective, so despite my large amount of data, the effective size is reduced due to this deduplication and compression, allowing me to store more data on the same storage. Regarding the impact of Dell PowerMax's real-time data encryption on my data protection strategies, I have not used that feature personally. However, in another department, my colleagues are using it, and they have not faced any performance bottlenecks due to data encryption. The encryption is very powerful, but I have not implemented that encryption in our database data warehouse systems since they are for internal use only, not exposed worldwide. At first, I faced several issues, and our report rendering complaints were quite annoying. However, now with Dell PowerMax storage's high IOPS handling capabilities, the output comes within a fraction of a second, making our users happy. Whatever our requirement or demand is, it has already been implemented in Dell PowerMax with its all-flash NVMe storage. New bricks can also be added if a size increase is required, allowing for additional bricks to be added as needed. Everything is in place; therefore, I do not think any other improvements are required. However, it is worth noting that Dell is continuously inventing and releasing more powerful types of storage. This results in increased reliability, enhanced data handling capabilities, improved deduplication ratios, and the fulfillment of more IOPS demand.

Quotes from Members

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

Pros

"The sales and executive support have been outstanding compared to the rest of the market... My upgrade paths have been simple on the Pure... It's a lot simpler to implement and a lot simpler to manage."
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"I cannot imagine my workflow without Everpure FlashArray because I do not have any other type of storage in use."
"The scalability is good."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"We are using the solution's application and snapshot feature."
"Six months in, we have ROI."
"The product is very fast and reliable."
"The response time, compared to XtremIO, is far better."
"The features of Dell PowerMax that I find most valuable so far include its all-flash capability, along with its performance, reliability, and efficiency."
"Before we deployed this solution, we used to struggle with processing about 100,000 transactions in 10 minutes; we are now able to process about 350,000 or more transactions, and conservatively, we are able to see about 300% performance improvement as compared to the SSD storage that we had previously from IBM."
"PowerMax NVMe has made it a lot easier to understand how much we are able to provision. It has made it a lot faster to provision new things. 90% of my time for provisioning has been reduced. Also, it has made it very easy to understand and see everything behind it versus the older heritage, where Dell EMC was very convoluted and hard to get working. Things that used to take an hour, probably now take five to 10 minutes."
"We have no performance related issues due to hardware."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"The solution is very easy to set up."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"Lenovo ThinkSystem DE Series is simple to use"
"The solution's initial setup process is easy."
"The solution is very easy to troubleshoot, it doesn't take long to deploy, normally comes with a three-year warranty, and has the most features if you compare it to other models."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
 

Cons

"Had some issues with Purity not being entirely compatible with VMware ESXi."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"We have not had a good experience with the IBM device."
"Automation could be simplified."
"The product could improve by providing the capability to support NAS storage – CIFS and NFS."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"If they could make it cheaper, that would be something."
"The size and weight of Dell PowerMax are quite cumbersome."
"There is room for improvement in adjusting into the existing infrastructure easily without much of the technical contribution."
"The size and weight of Dell PowerMax are quite cumbersome."
"It's a relatively new product, but for the next release I would like to see higher bandwidth on the front-end adapters."
"We would like more documentation, a guide to the features of the PowerMax."
"The price could be lower, and we are unhappy with the price."
"My understanding is that Dell PowerMax is very expensive."
"I would like it to support NVMe over Fabrics, because that is the next item for consideration on the NVMe roadmap."
"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."
"There could be a snapshot feature in the solution."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"The solution could be more scalable, although it suits our present needs."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
 

Pricing and Cost Advice

"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"The price is too high."
"The pricing is very attractive and it delivers performance for the money."
"There are no licensing fees or other costs."
"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."
"The solution could be cheaper."
"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."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"Our costs are on a yearly basis."
"It scales enormously, but it's expensive to do so."
"The pricing might be a bit high for small organizations, so it's more suitable for larger enterprises."
"The cost of the solution is quite noticeable, but it provides a good fit regarding the price of the hardware and all of the required licenses."
"Dell offers various pricing models, including a pay-as-you-go option where storage is provided without upfront charges, billing only for used capacity. As a 360° partner, significant discounts are available."
"We hope that with the combination of both NVMe and SCM the next PowerMax will be much cheaper that the one which we acquired."
"The price is okay."
"The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive."
"The pricing for this solution is good compared to HP or Dell EMC."
"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."
"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."
"We have a five-year contract for providing support."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
