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

"It has improved my organization in the way that we have high reliability and faster access to our data."
"It's actually very stable"
"It's very fast, easy to use, and the cloud-based management is good."
"Pricing is very competitive, and it's better than other competitors, as we've looked at some of the other competitors on the market."
"The most valuable feature is that maintenance is free."
"We find the ease of usability and setup valuable."
"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."
"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."
"We saved money by moving off old storage and we gained extra capacity and speed."
"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."
"The solution is so easy to manage that I forget it is there."
"The most valuable aspect of this solution is that it's a single block, a complete block that includes both NAS and SAN."
"I like that the performance is very good."
"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."
"It will certainly help us scale bigger. If I look at the footprint, the VNX's was multi-rack. Now, all of a sudden, we're only at a portion of a rack. And, obviously, if we can scale within the same rack - we can certainly see that by the number of hard drives we've had to put in - we can scale a lot more easily."
"The performance combined with the gig-per-dollar value is a combination that 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 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."
"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."
"The solution's initial setup process is easy."
"The solution is very easy to set up."
"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."
 

Cons

"I would like to see data tiering to AWS."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"It is way in excess of what we need. If anything, we could see a bit more speed."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level."
"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 price of this solution could be improved."
"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"I would like better monitoring capabilities: more historical data with more insight into the performance for the database."
"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."
"It's not really scalable. Up to mid-range requirements, it's just fine."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"We did encounter a firmware bug which actually caused loss of data. There was some heartburn around that. But in general, it has operated as expected, except for that bug."
"It is expensive, and the pricing could be better."
"It is missing some features, like deduplication."
"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 is really entry-level. In the next release, I would like to see more functionality."
"Scalability on rack-mount servers is not as good as with Blade servers."
"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."
"There could be a snapshot feature in the solution."
 

Pricing and Cost Advice

"It is a cheaper solution."
"There is always room for negotiation."
"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."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"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."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"It is priced at around or under $50,000."
"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."
"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."
"The pricing for this solution is good compared to HP or Dell EMC."
"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 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."
"It is an expensive solution."
