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.

Resilience has supported proactive management and secured audit readiness across multiple sites
The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

Quotes from Members

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

Pros

"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"The biggest return on investment for us is not having to do a swap out of the arrays every five years."
"It helps to simplify storage because it has an easy front-end to access everything."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"It solved many problems and provided unexpected features that improved our business execution, making us more agile internally."
"The code upgrades are very smooth."
"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."
"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"Dell PowerStore has definitely helped my customers improve their operational efficiency, as they can use their operations more efficiently with it."
"I really appreciate the management and the management console of Dell PowerStore along with features such as deduplication."
"Dell PowerStore has impacted my organization positively as it is a very easy system to use, so from an operational standpoint, I would emphasize its ease of use."
"The most valuable feature is that it is easy to use this frame. I am a SAN administrator, but I was able to train my colleague, who had only been a VMware administrator, on the PowerStore in about half a day. Now he's autonomous in assigning volumes and creating data stores..."
"This solution allowed us to consolidate our storage efforts and operate with less of a footprint."
"Dell PowerStore has positively impacted my organization by delivering great customer experiences that lead to repeat buyers and make it easier for us to maintain customers and have them come back and buy again from us."
"It has its own file formatting protocol, which saves a lot of space."
"The management console of Dell PowerStore is very easy to navigate through, and there have been no problems accessing it in any of the common browsers used, including Chrome, Firefox, and Edge, making configurations easier because everything is visible in plain sight through a graphical interface."
"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."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"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 quite an elementary box, no frills; it does not have all the functionality of the DM but it is acceptable, it does its task, and it integrates pretty well."
"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."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Lenovo ThinkSystem DE Series is simple to use"
 

Cons

"The price could be better."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"I would like to see support for NVMe, end-to-end."
"They could improve the price."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"It doesn’t provide enough information on performance analytics. For example, Nimble Storage has Infosight, which provides data; Pure Storage doesn’t have an equivalent."
"I have experienced many stability issues with Dell PowerStore. Every time we get a bad battery, we encounter problems."
"The service user is only used with the CLI and cannot log into the GUI, which is not a good feature because you cannot perform any maintenance from the GUI."
"The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal."
"The storage could be improved. I would like a feature for how to best secure an appliance and the storage since we are connecting the container to the public cloud. I would like them to develop another level of security, making it more secure than from what they have now."
"The only weirdness is we have a 7920 that trying to get into with the password is just not the same as the other enterprise models will have it."
"The biggest area in PowerStore that needs improvement is the overall visibility within the ESX environment."
"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."
"From my experience, Dell PowerStore is the best option on the market at the moment, but the worst thing is the price, which is too high compared to IBM or other vendors."
"Scalability on rack-mount servers is not as good as with Blade servers."
"The product could support advanced software integrations."
"Its performance could be faster."
"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."
"The features are limited."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"Improvements can be made to the product's performance."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
 

Pricing and Cost Advice

"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"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."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"The price is too high."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"It is expensive compared to one of its competitors."
"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."
"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."
"HCL Tech has a TLA with Dell, so in terms of price point, we are very competitive. Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market."
"The solution is expensive."
"I rate the price of Dell PowerStore a seven out of ten."
"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."
"There's still a cap on the upgrade path, where you can consume all the engines within the frame before you have to go to another frame... Normally, we exceed the IOPS on the frames before we can ever exhaust the storage, so anything they can do to help us avoid stranded storage capacity, capacity that we couldn't get to, would be beneficial."
"The solution's price could be better."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"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."
"The pricing is fair and low compared to other products in this category."
"The pricing for this solution is good compared to HP or Dell EMC."
