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

"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."
"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."
"There is no comparison performance-wise."
"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over. We have had almost zero stability issues with that SAN, that has been really great for us."
"Firstly, dedupe is the most valuable feature, hands down, and simplifying storage is also a big win overall."
"The all-flash disc is the most valuable feature of this solution."
"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."
"We chose Pure Storage primarily because of its combination of performance and ease of use."
"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."
"Dell EMC's technical support is perfect."
"Dell EMC Unity XT has good integration with VMware."
"From a functionality perspective on cost-effectiveness, it is exceeding all expectations."
"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."
"The biggest improvement is the data reduction for the organization; that is where they see the better TCO and improved ROI for their existing footprint."
"My advice for anybody who is considering the Dell Unity XT is to just enjoy it."
"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."
"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. It integrates pretty well."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"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."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Lenovo ThinkSystem DE Series is simple to use"
 

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."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"The solution is not cheap. It's much more expensive than DataCore."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."
"There's always an opportunity for new feature functionality."
"It might be nice to have more integrated features instead of having everything as a separate module, like the networking. The networking is attached separately in the back. It would be nice if that was more integrated with less ports."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"The price has room for improvement."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."
"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."
"Improvements can be made to the product's performance."
"There could be a snapshot feature in the solution."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"Scalability on rack-mount servers is not as good as with Blade servers."
"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 solution could be more scalable, although it suits our present needs."
"The product could support advanced software integrations."
 

Pricing and Cost Advice

"Pure Storage FlashArray's pricing is very competitive."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"Pure came in at a better price point than EMC and performed better than Compellent."
"The pricing of Pure Storage FlashArray is reasonable."
"Pure Storage FlashArray is expensive."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"The price was more favorable than Dell EMC."
"All storage is expensive so any price improvement would help."
"The ROI is right where we need it to be. It's a reasonably priced array."
"It is an average priced solution."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."
"Pricing for this product is manageable, though slightly higher than comparable products."
"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."
"Obtaining a warranty is easy."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"The solution's price could be better."
"The best thing about this solution is its price, which reduces our costs."
"The pricing for this solution is good compared to HP or Dell EMC."
"The pricing is fair and low compared to other products in this category."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"We have a five-year contract for providing support."
"It is an expensive solution."
"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."
