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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It does everything they say it will do: It's very cost-effective compared to other big players, integrates very well with VMware, is tiny so we're saving power and space in the data center, and it's really easy for us to manage."
"Very stable; no worries about how much it can handle."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"I am very satisfied with this solution and I would recommend it to others."
"The experience has been very good so far for the company."
"The Direct FlashArray stands out as one of the best features in the market. The Pure1 storage management lets us see the details about utilization and everything else for all 40 storage boxes in one place."
"Pure Storage FlashArray has helped decrease the total cost of ownership because we know what the cost is going to be every year; we don't get any hidden fees or upgrade fees, everything is included in the price."
"It's very fast, easy to use, and the cloud-based management is good."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"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."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"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, and it integrates pretty well."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. 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."
"We have had such a good experience with NetApp that our next logical step up from our previous device was just another NetApp."
"If you are looking for high-performance, reliable, multi-tenancy supporting equipment, then this is a very valid, legitimate solution with a proven background and history."
"The speed and stability are the two most valuable features, and I've definitely seen a huge increase in speed and bandwidth from when we put it in production; it's been great."
"For me, the most valuable feature is the simplicity of being able to have a pool of storage and not worry about how many IOPS I need, how many disks, or carving up aggregates."
"It's really, really good for everything that we've used it for."
"The speed and low latency are the most valuable features, and my customers or users noticed an improvement in our EMR application once we moved our SQL environment over to the AFF."
"The most valuable feature is the support. If we have any issues, we can call into NetApp and their support is really good."
"We have a comprehensive solution that could accommodate anything. We can fly it earlier and get them in the air testing and prototyping much faster than they could have with other solutions."
 

Cons

"Price is about the only thing that's wrong with it."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. 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. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"There could be a snapshot feature in the solution."
"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."
"Improvements can be made to the product's performance."
"Its performance could be faster."
"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."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"Software packaging and ordering. We wanted to integrate with replication and Commvault options, and that was difficult."
"Cleaning up false positives on alerts. We get a lot of those."
"I really don't have anything to ask for in this regard, because we're not really pushing the envelope on any of our use cases. NetApp is really staying out ahead of all of our needs. I believe that there were firmware issues. I think it was just a mismatch of things that were going on. It could have possibly been something in the deployment process that wasn't done exactly right."
"The price needs to come down. Also, it has a learning curve and I needed to learn a lot to do the installation."
"When you look at the competitors, they have some features available, for example on the deduplication side.​"
"In the first years it was great, after that it has become worse."
"The graphical interface is still heavy and slow. Needs more improvement in this area."
"The licensing cost of the product is expensive, and when combined with support, it becomes quite costly."
 

Pricing and Cost Advice

"The price of Pure Storage FlashArray is expensive."
"For us, as the customer, it reduced the price of the management."
"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"We are finding the TCO of flash to be lower than SSD implementations."
"The solution could be cheaper."
"It's expensive, but you get what you pay for."
"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."
"The best thing about this solution is its price, which reduces our costs."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"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."
"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."
"The pricing is fair and low compared to other products in this category."
"We have a five-year contract for providing support."
"I do not deal with pricing, but the pricing of NetApp and Dell seems pretty close. NetApp support is cheaper than Dell support."
"I would like it to be a lot less expensive, but it's been a very good solution for us."
"It's expensive. it's in the hundreds of thousands. It's beneficial, but at times, I feel compared to other vendors, we are paying a premium for the licensing that other vendors include."
"We have been able to utilize and leverage equipment which was purchased a decade ago up until this past year. So, we were running disk shells for 13 years and all we were doing was upgrading the filings and controllers, and using the same disk shells. Therefore, we were able to do something where we didn't have to invest that much. Recently, we had to upgrade all our disk shells, but it was a lot less because the technology had changed a lot since those times. It is faster now, and we have SSDs. We have larger drives that are 4TBs and 6TBs. Everything can condense so we are saving disk shell space and rack space. We are paying less now than we did at that time"
"It is pretty expensive compared to other solutions. I would give it a seven or eight out of 10 in price (where 10 is expensive) compared to similar solutions."
"We don't like the cost. We would like to buy more."
"If you go for Replication, Vault, and NAS, please ensure that the license has been ordered at the very beginning. However, licenses can been added or modified without rebooting the system at any time."
"Planning of all the lifecycle storage with NetApp AFF is part of the solution. While it is not cheap, they have introduced a new series of AFF that are more affordable, providing options for more users."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
