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.

Cloud data management that achieves cost efficiency with advanced data protection features
I am currently using Nasuni for seismic data. We have a huge data size, and we want to reduce costs. Nasuni acts as a caching solution, so we put some data into the cache, and the rest goes to the blob, which helps us save on costs. We use it for applications like Petrol and Tech Log, where 3D…

Quotes from Members

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

Pros

"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."
"Pure gives us better compression, it's easier to manage, a lot less hands-on."
"The performance is great."
"We are very happy with the data deduplication and compression ratio that we have on the platform."
"The top-tier support and reliable storage are the most valuable features of this solution."
"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."
"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"The solution helps to simplify storage."
"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 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."
"Lenovo ThinkSystem DE Series is simple 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."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution's initial setup process is easy."
"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 ability to access anywhere, the ease of deployment, and the security are the most valuable features."
"I can see who is logging in on files from all over the globe. For example, if a file is locked, maybe a user in Shanghai has locked files or something, I can see that from the Management Console, then unlock the file."
"The most valuable feature is disaster recovery. We can fully recover a site in two hours."
"The Nasuni management dashboard is helpful because, on the administration side, I'm able to view all of the different filers that we have in the UK, rather than check each one of them individually."
"The most valuable feature is the storage in that it only keeps the last-used data locally, while everything else is backed up to the cloud. That way, we never really have to worry about file space in each office or the replication to the other file servers for DR."
"I would recommend Nasuni because it's a proven product that has delivered results for us even in the worst-case scenario. If you're still using a traditional cloud solution like native Azure products, you are still susceptible to human error. Also, you would need to architect your backup and DR solutions, then integrate, maintain, and administer them."
"The most valuable feature is that we have redundancy in our data. It's nice to know that it is cached both locally on the filters, as well as stored on that cloud."
"A big advantage is having the data exist in the cloud, which has certainly relieved a lot of pressure from our IT department in regards to having a backup as well as preventing some ransomware in all of our offices."
 

Cons

"The price should be lower."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."
"The product could improve by providing the capability to support NAS storage – CIFS and NFS."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"There are many features which need to be added, particularly on the replication side."
"Going forward, don't complicate things for the customers."
"The product could support advanced software integrations."
"Improvements can be made to the product's performance."
"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."
"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 solution could be more scalable, although it suits our present needs."
"The features are limited."
"Its performance could be faster."
"I would like to see Nasuni create a Dropbox or Box alternative. One of the things that people like about those tools is that they are very easy to implement. They look just like a file server. With Nasuni, you have to be online to get your file storage. With Dropbox, there is a thing running on your PC that downloads the files to it when you need them, i.e., an agent."
"One area that we've recently spoken to Nasuni about is single sign-on."
"Nasuni could improve cloud integration and documentation of various ways we can leverage the product. It integrates with Azure, but the native Azure File Sync solution lets you divide data into tiers like hot, cool, and archived. Nasuni doesn't allow you to break the data apart into those tiered categories."
"I would like to see them improve their tools in regards to accessing data using smartphones, tablets, and iPads. I think the Nasuni app could be improved to make access to the data cleaner and more efficient."
"One area that we've recently spoken to Nasuni about is single sign-on. Another is integrating Nasuni with Azure Active Directory. In our particular case, that would allow for third-party consultants to access our Azure Active Directory environment as opposed to coming to our on-premises environment."
"Its pricing can get a tad expensive."
"We forecasted that the data at my client's organization would grow by about ten percent annually, but we are migrating more data because we are bringing in some servers that had not previously been within the scope of our license. We expected it would take us two years to reach a specific amount of data, but we hit that mark in one year. The licensing cost skyrocketed, so we need to renegotiate. It puts us in a bind because we are reliant on Nasuni for our service strategy. We can't deny our customers, but we also struggle to pay for that."
"Some of their cross-platform features are really good, but it could always use more."
 

Pricing and Cost Advice

"There are no licensing fees or other costs."
"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."
"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."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"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."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"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."
"It is an expensive solution."
"The solution's price could be better."
"The pricing for this solution is good compared to HP or Dell EMC."
"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."
"Our agreement is set up such that we pay annually per terabyte, and we buy a chunk of it at a time. Then if we run out of space, we go back to them and buy another chunk."
"It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."
"It is around $850 per terabyte per year. Any additional costs that you would incur are for the local caching devices that you'll need to access Nasuni. You kind of provide your own virtual machines or compute to access the data. You also pay for the object storage. So, there are three parts to it. There is the Nasuni license per terabyte. You would also pay for the actual object storage in the cloud, and then you would pay for virtual machines to access the storage."
"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
"The cost of licensing is negotiated and billed annually per terabyte."
"Nasuni pricing is average; it's not too high or too low."
"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."
"I would not say it is economically priced, but it is affordable. If you can afford to pay for it, it is worth the money, but it is definitely not overpriced. It is priced about where it needs to be in the market. We were satisfied with the way they did their licensing and how they handled it. I believe they actually license by data size. It is based on how much data is being held on the machine and replicated, and that's completely understandable. So, for us, their pricing was as expected and affordable."
