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.

I use Lenovo ThinkSystem DE Series to replace the old storage in our infrastructure. Additionally, I use it in customer infrastructures to migrate from the old storage to the new one On the M storage, I find the best features to be deduplication and compression. On the DE storage, the most…

Quotes from Members

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

Pros

"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases, and the scale of deployment basically went from several days to a few minutes."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"Performance, deduplication, compression, and fast response time for requests from servers and applications."
"It does everything they say it will do: It's very cost-effective compared to other big players, integrates very well with VMware, is tiny so we're saving power and space in the data center, and it's really easy for us to manage."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"The most important feature of any storage array is its reliability, measured by its uptime."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"It has compression, which allows you to store more data than you would normally under the arrays."
"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."
"The architecture is robust; it was the good, old-fashioned storage array, block array for customers, and it's reliable."
"The All-Flash models are intuitive and easy to work with, in addition to providing high IOPS with low latency to support Business Critical applications."
"It is easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened."
"My advice is to take this solution."
"It has reduced the latency in application and database reads and writes... All-flash, it's fast. We have the 650 model which is all-flash, upgraded from VNX. It just flies."
"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution's initial setup process is easy."
"The solution is very easy to set up."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
 

Cons

"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"The solution could improve by having a multi-tenant feature."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room."
"I would like to see more cloud integration."
"There was some complexity in the initial setup."
"The price has room for improvement."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."
"The only thing that could improve it would be a price reduction."
"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."
"A rating out of 10 out of 10 is a bit too much because, obviously, no product is super perfect, but I would rate the unity a good nine. What might make it a 10 is a better price."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"We would like to see the synchronous replication process included in the next release. Not having this downgraded our performance by 65 percent."
"It is really entry-level. In the next release, I would like to see more functionality."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"Improvements can be made to the product's performance."
"Improvements can be made to the product's performance."
"Its performance could be faster."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"The solution could be more scalable, although it suits our present needs."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
 

Pricing and Cost Advice

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"The licensing is $100,000."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."

"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"The solution is very expensive."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"The solution’s pricing is competitive."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"The pricing for this solution is good compared to HP or Dell EMC."
"The best thing about this solution is its price, which reduces our costs."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The solution's price could be better."
