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's overall speed is its most valuable feature."
"The technical support is very good."
"Pure support is very proactive, they monitor our infrastructure in real-time, so they respond before we even open a ticket."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"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 features that are there now are really what we need."
"The most valuable feature is its data reduction."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"Provides good provisioning, allowing us to save space."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example, and for our purposes, we find Unity simple to use."
"We put the Unity on one of the file servers and the backup performance improved quite a lot."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"We will probably implement it in other locations that we have as well, since we currently only use it at our main location."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."
"It is the performance combined with the Gig-per-dollar value; that combination is superior to other storage options."
"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."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"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 been working with the solution for around a year and so far it has shown itself to be stable."
"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."
"Lenovo ThinkSystem DE Series is simple to use"
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"Lenovo ThinkSystem DE Series is cost-effective; there is no license, all of the features are bundled together, and you can renew the bundle with all of the features included."
 

Cons

"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."
"I would love for them to have a hyper-converged solution."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"If they could make it cheaper, that would be something."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"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."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is."
"It is a bit expensive."
"Licensing costs could be reduced."
"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."
"The virtual appliance is limited to 4TB in storage."
"This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa."
"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."
"I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."
"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."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"There could be a snapshot feature in the solution."
"Its performance could be faster."
"Scalability on rack-mount servers is not as good as with Blade servers."
"Usually, when a part fails, we have to replace it and it takes a while."
"The product could support advanced software integrations."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"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 solution could be cheaper."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"We have seen a reduction in total cost of ownership."
"The price of Pure Storage FlashArray is expensive."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"It is cheaper than NetApp."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"I rate Dell Unity XT’s pricing a nine out of ten."
"Go with the virtual appliance versus the hardware."
"It is an average priced solution."
"From a pricing perspective, this solution is comparable to others on the market."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"We have a five-year contract for providing support."
"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 is fair and low compared to other products in this category."
"The solution's price could be better."
"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."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
