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

"Pure Storage FlashArray is simple and easy to use. It offers protection when removing devices. It has the ability to undo deletes."
"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."
"I can personally state that the Pure Storage Flash Systems are the best built and Pure has the utmost professional customer care."
"Access speed and power consumption are most valuable."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"This solution has helped my organization by cutting down on provisioning time; I used to have to provision a VM and it would take ten minutes, now, it takes thirty seconds."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"Dell Unity XT offers data integration features."
"This product is perfect for small, and mid-range customers who need to pay less, but still get enterprise-level capabilities."
"It has a very intuitive web console that runs in HTML5 and makes navigation and administration fairly easy."
"Once it is set up, it is definitely easy to manage."
"We are satisfied with the technical support."
"Dell Unity XT is a unified box, and it is integrated with VVOL, our software-defined storage."
"It is scalable. We can add additional tools if we need to expand it."
"On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Lenovo ThinkSystem DE Series is simple to use"
"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."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"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."
"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

"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"The price of the solution can improve."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"GUI updates. I had several hours helping support troubleshoot the difference in what the system was doing compared to what the GUI said."
"Thick provisioning of LUNs."
"Sometimes the response time is higher than expected due to a lack of issues."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"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 monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult."
"Yes, we had an issue in January with a Service Processor rebooting unexpectedly."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"It would be useful to have structured solutions replicated to other sites."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"Its performance could be faster."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"Scalability on rack-mount servers is not as good as with Blade servers."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"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."
 

Pricing and Cost Advice

"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."
"Pricing is moderate. It is neither cheap nor expensive."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"We have seen a reduction in total cost of ownership."
"We have seen a reduction in TCO."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"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."
"Pure Storage has not helped to reduce our HANA licensing costs."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"This solution offers great pricing."
"The solution should be cheaper."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"While Dell EMC is costly, I don't have any complaints about their licensing model."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"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."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The best thing about this solution is its price, which reduces our costs."
"The pricing is fair and low compared to other products in this category."
"It is an expensive solution."
"The solution's price could be better."
