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

"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"It is an easy to use product for all of my team members."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"Everpure FlashArray is very good with AI development and is very suitable for low downtime and critical mission storage, so customers who need critical mission storage and those chasing performance should consider this solution."
"The solution has great efficiencies because it has scalability."
"I find Pure Storage FlashArray to be much better than traditional storage because it has a GUI interface. It makes the process of allocating the storage much easier, and most activities are automated. It is like clicking a button for every task."
"The most valuable feature is it never goes down. We can expand and create volumes."
"Technical support is very good."
"In my all installations, customers were very satisfied."
"Unity has reduced the complexity and improved productivity tenfold compared to what it used to be."
"Performance is a top feature."
"Dell EMC Unity is actually one of my market focuses, from the understanding that Dell EMC has redefined the core of their mid-range storage portfolio, focusing on two main products: Dell EMC SC (Dell legacy Compellent) and Dell EMC Unity (the last mid-range storage solution developed by the former EMC, just prior to committing the fusion with Dell)."
"I would definitely recommend Unity because, compared to VNX and other storage solutions, it is the easiest way to deploy for VMware and physical operating system services."
"We have seen a huge performance increase due to all-flash that is beyond what was anticipated."
"For me, the best thing is the reliability."
"It is easy to manage; a lot of the system manages itself, and it is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Its initial setup process is easy."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"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 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."
 

Cons

"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current."
"Going forward, don't complicate things for the customers."
"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"It can go down from time to time, but it's been pretty solid so far."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says it is completely full."
"The price of this product can be more cost-effective."
"There is room for improvement in manufacturing."
"If the product could only send alert notification via SMS, it would be much better."
"The only room for improvement I can see would be a faster lead time and lower cost."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint."
"The initial setup is not so straightforward if you don't have experience with storage arrays."
"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."
"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."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"Usually, when a part fails, we have to replace it and it takes a while."
"Its performance could be faster."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
 

Pricing and Cost Advice

"We lost a lot of customers because we couldn't compete on price with other vendors."
"It's a good price point and it's a solid product for the price."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The price was more favorable than Dell EMC."
"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."
"For us, as the customer, it reduced the price of the management."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"The ROI is right where we need it to be. It's a reasonably priced array."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"I rate Dell Unity XT’s pricing a nine out of ten."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"We have a five-year contract for providing support."
"The best thing about this solution is its price, which reduces our costs."
"The solution's price could be better."
"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."
"The pricing for this solution is good compared to HP or Dell EMC."
