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

"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The money I saved by not renewing maintenance on the Dell EMC devices paid for the Pure Storage devices."
"The experience has been very good so far for the company."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"We consume less physical storage because of the solution’s deduplication and compression."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"We saved money by moving off old storage and we gained extra capacity and speed."
"The Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning."
"Setup is simple, but at the expense of key management features."
"The return on investment is in the fact that it meets all of our storage needs and in the ease of expanding it."
"The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like."
"We use replication for disaster recovery (DR), making our DR process much easier."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Lenovo ThinkSystem DE Series is simple to use"
"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."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"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 highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
 

Cons

"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"The scalability of the solution is not as good as it probably could be."
"The areas that have room for improvement include the scheduling process for upgrades."
"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."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"Self-backup is the only feature lacking in this solution."
"I would like to see some improvements on the FlashBlade side around the CIFS space support."
"The dedupe and compression ratios on the Unity are not quite where we want them."
"It should be lighter. It takes up a ton of rack space."
"It would be better if there were more integrations."
"I would like the UI to look better."
"Compression and block deduplication on non-all-flash solutions."
"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"We would like to see the concept of Storage Groups brought back to this product line."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"Improvements can be made to the product's performance."
"Improvements can be made to the product's performance."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"It would be useful to have structured solutions replicated to other sites."
 

Pricing and Cost Advice

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"The price is reasonable."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"Pure Storage has not helped us to reduce our licensing costs."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"I would rate it a seven out of ten for pricing. It could be improved."
"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."
"We lost a lot of customers because we couldn't compete on price with other vendors."
"The ROI is right where we need it to be. It's a reasonably priced array."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"The support you're getting with it is probably an underestimated value that comes with the box you're buying."
"Pricing is as high as it has ever been for EMC."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"The solution should be cheaper."
"This solution is a good price for what you get."
"The pricing is fair and low compared to other products in this category."
"It is an expensive solution."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The solution's price could be better."
"We have a five-year contract for providing support."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"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 for this solution is good compared to HP or Dell EMC."
