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

"We noticed a dramatic increase in application performance when moving it from NetApp to Pure Storage."
"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."
"Our clients see a reduction in total cost of ownership by around 40%."
"This solution has improved my organization because it has good performance."
"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage; the ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"The pricing of Pure Storage is all-inclusive; it is very fair, very easy, and the solution is a lot easier to install than the Dell EMC product."
"I am very satisfied with this solution and I would recommend it to others."
"It can be simple to deploy, the standup time is quite quick, the interface is quite quick, the terms are simple and intuitive, it's similar to what was there in the VNXE before it, and it's very simple to navigate and administer from the console."
"We just started doing a bunch of automation where, if an end-user's home directory or departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us."
"Tech support is good."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."
"It increased our uptime because we switched from physical stuff to virtual stuff, and being able to have that we could do the high-availability and failover."
"This solution makes it easy to manage storage, provision new workloads, and scale-up."
"We went through a scale-up and it performed as expected."
"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."
"Lenovo ThinkSystem DE Series is simple to use"
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"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."
"Its initial setup process is easy."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
 

Cons

"Going forward, don't complicate things for the customers."
"Most of our upgrades have not been as smooth as they should have been."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"There are many features which need to be added, particularly on the replication side."
"The price of this solution is high and should be lowered."
"I would like to see them develop the ability to integrate with more AWS services."
"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."
"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."
"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to be enhanced."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"The iSCSI and the VMware integation using vSphere could be less confusing."
"They're slow to implement new innovation with their product. EMC doesn't really innovate; they just sit there and wait for other people to innovate, and then they just copy."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"The product could support advanced software integrations."
"The solution could be more scalable, although it suits our present needs."
"Improvements can be made to the product's performance."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"While it is a reliable product, it could be improved. 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."
 

Pricing and Cost Advice

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"There is an annual or perpetual license required for this solution."
"We have an Evergreen Storage subscription, which I think is a great feature."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"The pricing of Pure Storage FlashArray is reasonable."
"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."
"It is light years beyond anything else with the same price point."
"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"Licensing is easy since all the software is included."
"The solution should be cheaper."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"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."
"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."
"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."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"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."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
