Featured Reviews

Sowjanya MV

Technical Lead at Wipro Limited

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.

Unified management and cost-effectiveness lead to positive experiences and future savings

Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

A nicely-done product that provides a lot of graphs and reports to see what's happening in the background and makes configuration easier

It's very well done for what it's supposed to do, and I don't have anything to add, but I would like them to keep it available to the public. SwiftStack is going out of the market. NVIDIA purchased SwiftStack a couple of years ago, and they won't be making it available to the public anymore. Our license is up to March 31st.

Quotes from Members

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

Pros

"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."

"For VMware, it has been a humongous savings."

"The speed is one of the most valuable features of Pure Storage FlashArray."

"The solution is very reliable."

"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."

"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."

"I would highly recommend this solution; it has all the features we need and tests all the software solutions that are currently available and that will be available in the future."

"The performance is very good."

More Everpure FlashArray pros

"I rate Nutanix Unified Storage (NUS) a ten out of ten."

"One of the best features of Nutanix Unified Storage (NUS) is the ability to deliver file, object, and block storage from a single unified storage platform, along with native integration into the Nutanix Prism for centralized and simplified management."

"The reliability and stability of Nutanix Unified Storage (NUS) are very good, and after almost four or five years of usage, we haven't encountered significant issues."

"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."

"One of the main features of Nutanix Unified Storage (NUS) that I find most valuable is the flexibility and scalability of it, as well as the ability to perform replication for our Disaster Recovery environment."

"Nutanix Objects is reliable."

"We have seen reduced overheads and increased efficiency with Nutanix Unified Storage (NUS)."

"What I found to be the most valuable features were better performance and uptime."

More Nutanix Unified Storage (NUS) pros

"The most valuable feature is its versatility. We use 1space and we can use it for almost anything: for our cloud service, for backups of VMs."

"SwiftStack is also quite flexible when it comes to hardware. It depends, of course, on the use case and the kind of hardware you want to buy. But you have quite a bit of choice in hardware. The SwiftStack software itself does not impose anything on you."

"The quality is really good, the stability is fantastic, and it requires very little manpower."

"The biggest feature, the biggest reason we went with SwiftStack, rather than deploying our own model with OpenStack Swift, was their deployment model. That was really the primary point in our purchase decision, back when we initially deployed. It took my installation time from days to hours, for deployment in our environment, versus deploying OpenStack Swift ourselves, manually."

"It has helped us with the ability to distribute data to different data centers. As part of our DR strategy, we have nodes automatically replicating data from one data center to the other. This makes it easier for us to not have to shift tapes around."

"The impact on our business was that we launched a new product which has allowed us to generate additional revenue for our business with it."

"The SwiftStack Controller, which is the web UI, provides out of band management. This has been one of the best features of it. It allows us to be able to do upgrades and look at performance metrics. It is a top feature and reason to choose the product."

"Management of clusters is easy and it is simple to reduce the man hours needed for a deployment."

More SwiftStack [EOL] pros

Cons

"They should work on their upgrades, they're not smooth."

"The data reduction that we had initially anticipated when we bought Pure and we moved over is way lower than the expected reduction."

"Pure Storage will have issues with positioning in the near future since it's a relatively new company."

"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."

"When creating a support case, visibility should be extended to others involved in assisting."

"Pure Storage FlashArray has not helped to decrease the total cost of ownership, and I believe our total cost has probably gone up, but that's balanced by our increased amount of data and number of use cases."

"I would like to have support available in Spanish."

More Everpure FlashArray cons

"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."

"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."

"Unified Storage failed to fulfill our object storage requirements."

"Improvement is needed regarding clarification to customers about storage capacity. While 100% storage is allocated, customers can only access 70 to 80% when examining deeply."

"Its interface is very simplistic. It is a good thing for people because of the ease of use, but at times, I find it too simplistic. It is hard to find advanced options. They should eventually expand it and provide additional drop-down lists or menus with advanced feature sets."

"When considering the difference in cost benefits, if you consider it only as a storage solution, you may find it expensive."

"It could be more user-friendly."

"Nutanix should improve the one-click upgrade. There are a lot of dependencies on third-party licenses and HP hardware we use internally, and the one-click upgrade fails sometimes."

More Nutanix Unified Storage (NUS) cons

"The biggest room for improvement is the maturity of the proxyFS solution."

"It's very well done for what it's supposed to do, and I don't have anything to add, but I would like them to keep it available to the public. SwiftStack is going out of the market. NVIDIA purchased SwiftStack a couple of years ago, and they won't be making it available to the public anymore. Our license is up to March 31st."

"[One] thing that I've been looking for, for years as an end user and customer, for any object store, including SwiftStack, is some type of automated method for data archiving."

"The biggest room for improvement is the maturity of the proxyFS solution. That piece of code is relatively new, so most of our issues have been around the proxyFS."

"The file access needs improvement. The NFS was rolled out as a single service; it needs to be fully integrated into the proxy in a highly available fashion, like the regular proxy access is."

"I would like to see better client integrations, support for a broader client library. SwiftStack could be a little bit more involved in the client side: Python, Java, C, etc."

"Don't use it because it will go off the market in three months. It won't be available."

"On the controller features, there needs to be a bit more clean up of the user interface. There are a lot of options available on the GUI which might be better organized or compartmentalized. There are times when you are going through the user interface and you have to look around for where the setting may be. A little bit more attention to the organization of the user interface would be helpful."

More SwiftStack [EOL] cons

Pricing and Cost Advice

"We lost a lot of customers because we couldn't compete on price with other vendors."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

"We do not incur additional costs beyond the licensing fee."

"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."

"All storage is expensive so any price improvement would help."

"The cost has room for improvement."

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."

"We have seen a reduction in total cost of ownership."

More Everpure FlashArray pricing and cost advice

"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."

"My company is in Brazil, and making the payments in dollars is tough for our organization."

"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."

"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."

"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."

"For clients running Nutanix, the licensing cost for Files is a small add-on cost."

"In my opinion, the product is fairly priced."

"Nutanix Unified Storage was cheaper than other solutions we evaluated."

More Nutanix Unified Storage (NUS) pricing and cost advice

"We are able to dynamically grow storage at a lower cost. We can repurpose hardware and buy commodity hardware. There is a huge cost savings, on average $100,000 a year compared to traditional storage for what we have at our size."

"COST_SAVING; We have had a 40 to 50 percent reduction in CAPEX on the acquisition of new hardware, which is probably conservative."

"It's pricey for us because we're a nonprofit. I'm not privy to any amount or cost, but I have been told that it is pricey. There are no costs in addition to the licensing fees, and it seems to come with the support."

"The pricing and licensing are capacity-based, so it's hard to put my finger on them, because so many different vendors charge in different ways. We are still saving significantly over any of the other options that we evaluated because we can choose the best hardware at the best price, then put SwiftStack software on it. So, it's hard to complain, even though a part of me goes, "It would be nicer if it were less expensive.""

"We have had a 40 to 50 percent reduction in CAPEX on the acquisition of new hardware, which is probably conservative."

"The annual support and maintenance costs compared to our old solution for backups had about a two-thirds savings, so about a 60% annual savings on our support and maintenance contract. That savings funded additional expansion for what it was costing us for the support and maintenance contracts on old solution."

"Dollar per gigabyte, it costs us more because we are storing more. However, if you look at it from a cost per gigabyte perspective, we have dropped our costs significantly."

"We find the pricing rather steep. Of course, you get quality for your money, that's absolutely true... [But] when you look at the prices of the licensing and the prices of your hardware, it's quite substantial."
