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

"At this point, I don't know anything that they could provide in a better way."
"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"I would definitely suggest this solution to a colleague because of the ease of use."
"The deduplication and compression meet all of our system requirements."
"The solution helps to simplify storage."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"The management features are well organized and they have a very good dashboard."
"The availability and ease of use are the big features."
"We're using Dell EMC Unity as our primary storage for our production and for our DR site, we've had no performance issues with it whatsoever and we're using it for everything."
"Our end-users are happy with the product, there are no issues."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"The fact that it's hybrid is the most valuable feature. We have the SSD so we put our SharePoint on there and some of the stuff that requires a little more speed. For SharePoint, we want the pages to respond a little more quickly. And it's nice to be able to use the slower storage for stuff that we don't need as quickly, like file servers."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"We have seen a huge performance increase due to all-flash that is beyond what was anticipated."
"The Dell EMC Unity is a small but powerful storage solution."
"I would tell a colleague this makes a very sound investment."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"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."
"The solution's initial setup process is easy."
"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."
"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

"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."
"If they could make it cheaper, that would be something."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"We haven't seen ROI."
"I don't feel the product is the leader in the market anymore."
"One of the issues we've had is that controllers have crashed several times. We've had a lot of problems with the storage processor, SPBs."
"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."
"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."
"The virtual appliance is limited to 4TB in storage."
"Dell could improve Unity XT by adding support for NVMe."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."
"The monitoring capabilities should be improved."
"Improvements can be made to the product's performance."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The solution could be more scalable, although it suits our present needs."
"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."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"There could be a snapshot feature in the solution."
 

Pricing and Cost Advice

"The pricing is reasonable."
"The licensing is $100,000."
"Pricing is very competitive, and it's better than other competitors."
"The pricing is very attractive and it delivers performance for the money."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"There are no fees for licensing. The hardware is paid for only once."
"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."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"I rate Dell Unity XT’s pricing a nine out of ten."
"We have to apply for a license for each system."
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"It is a good return on investment."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing is fair and low compared to other products in this category."
"The best thing about this solution is its price, which reduces our costs."
"We have a five-year contract for providing support."
"The solution's price could be better."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The pricing for this solution is good compared to HP or Dell EMC."
"It is an expensive solution."
