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 support is very proactive, they monitor our infrastructure in real-time, so they respond before we even open a ticket."
"Pure Storage FlashArray is simple and easy to use. It offers protection when removing devices. It has the ability to undo deletes."
"If you're interested in using this solution, I recommend that you do the same — see if you like it."
"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."
"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."
"The most valuable feature is its data reduction."
"It is easy to deploy and it's all-flash, so it's very fast."
"For me, the most valuable feature is the ease of management."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"Replication of the communication object (COB) scenarios"
"It saves us time, it does not require a lot of admin from us."
"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."
"When comparing them all in their strengths for implementation, the lifecycle of the product, and the support they provide, I would rank Dell number one, IBM second, and third would be Fujitsu."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."
"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 simple to use"
"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 highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"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."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
 

Cons

"Storage. There could be better storage."
"Self-backup is the only feature lacking in this solution."
"Price is about the only thing that's wrong with it."
"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."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"The scalability of the solution is extremely costly."
"It falls far short of protocol support."
"The only thing that could improve it would be a price reduction."
"It could always use native replication. Then I could get rid of RecoverPoint."
"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."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"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."
"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."
"The pricing is a bit high. We'd like it to come down."
"Compression and block deduplication on non-all-flash solutions."
"There could be a snapshot feature in the solution."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"The product could support advanced software integrations."
"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."
"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."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
 

Pricing and Cost Advice

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"The solution is expensive."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"The pricing of Pure Storage FlashArray is reasonable."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"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."
"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."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"The solution should be cheaper."
"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The best thing about this solution is its price, which reduces our costs."
"It is an expensive solution."
"We have a five-year contract for providing support."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
