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.

Ease of implementation and robust performance enhance multi-OEM support experience
We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

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 the speed of it, as it is much faster than anything that we can get from similar competitors, and the solution helps to simplify storage."
"You get what you pay for; it is expensive, but it really works, so I would really recommend using Pure Storage."
"It is simple, powerful, and a beautiful solution."
"Provides fast access and is user-friendly."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"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 has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."
"Pure gives us better compression, it's easier to manage, a lot less hands-on, and the biggest selling point for me was the replacement of the hardware, the controllers, without any major expense to the clinic."
"I cannot stress enough how simple and easy it is to set up and use and manage."
"Overall it is a stable versatile solution."
"This solution helped us reduce our physical footprint and power consumption."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"I've had so many nightmares with so many other arrays, but I have no complaints with Dell EMC Unity at this time."
"It is stable, I have not personally seen any issues when deploying in a customer environment."
"Replication and ease of storage setup for block LUN’s and VMware."
"Unity XT is very good compared to Fujitsu and IBM."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"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."
"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."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"The solution's 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."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
 

Cons

"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation."
"It was a little costly."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"It's expensive, but you get what you pay for."
"We have not seen a reduction in our TCO nor have we seen ROI."
"Pure Storage FlashArray could improve by being more secure."
"The main disadvantage of Pure Storage FlashArray is the price."
"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."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"I would like them to continue to build on the solution and expand on the functionality, like replication."
"We have had some downtime. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas."
"The only thing that could improve it would be a price reduction."
"I would like to have secure mobile connectivity going forward. This would help me be more proactive."
"This solution would be improved with the addition of flexible raid volumes."
"The solution could be more scalable, although it suits our present needs."
"It is really entry-level. In the next release, I would like to see more functionality."
"The product could support advanced software integrations."
"It would be useful to have structured solutions replicated to other sites."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"In the next release, I would like to see support for Hyper-converged infrastructure."
 

Pricing and Cost Advice

"There is an annual or perpetual license required for this solution."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"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."
"We are finding the TCO of flash to be lower than SSD implementations."
"Pure has been flexible with us on the pricing models."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"We have seen a reduction in total cost of ownership."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."
"We purchased a five-year warranty."
"There is not a license required for the use of the solution. We purchased a maintenance contract."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"It is an average priced solution."
"The solution is very expensive."
"The solution's price could be better."
"The pricing for this solution is good compared to HP or Dell EMC."
"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."
"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 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."
"It is an expensive solution."
