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.

Principle Technical Specialist at a comms service provider with 1,001-5,000 employees

Unified storage has simplified private cloud operations and delivers strong security and ROI

Regarding areas for improvement, I think Data Lens could be enhanced from Nutanix's side, but it has been a long time since I logged into that console, so I do not remember much. It is a SaaS-based offering on the Nutanix portal. It is not something you deploy on-premises; it is not on-prem access. You connect your cluster to the SaaS-based Nutanix and then access the Lens console. I need to check it since it has been almost two or three months since I logged in. Nutanix Enterprise AI actually needs to improve a lot if I compare it with any other product such as NVIDIA and other offerings in the market. Nutanix Enterprise AI still requires a lot of work. I did not check that in much detail technically, but whatever I thoroughly checked, it still lags behind in many features. When it comes to AI-related features, I think the ecosystem of Nutanix is not as big as NVIDIA because NVIDIA has its own inferencing system and model training platform such as NeMo, NeMoTron, and others. Nutanix does not have such things. It can be built using NVIDIA CUDA libraries, but what I saw when I was testing the product is that you can run NVIDIA NeMo and PyTorch and two other things, but as a software, Nutanix does not have an end-to-end platform. That is something Nutanix should focus on.

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

"We tested our VDI environment on this array and it performed flawlessly and boosted the user experience."

"The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."

"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases, and the scale of deployment basically went from several days to a few minutes."

"The solution offers amazing performance."

"It has simplified our storage."

"If you need faster storage and a good product, this is the one you should go ahead with."

"The performance is very good."

"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."

More Everpure FlashArray pros

"I have found Nutanix Volumes highly stable with good performance."

"Nutanix Unified Storage (NUS) has simplified my storage management across different workloads and improved application performance and availability while supporting hybrid cloud and modern applications with centralized management."

"The most valuable features are the interface and support."

"The product's benefits stem from the ease of use and management it offers to its users."

"Nutanix Objects is reliable."

"The most valuable features of Nutanix Unified Storage are the unified dashboard and the ease of administration."

"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."

"DR and the replication power are valuable."

More Nutanix Unified Storage (NUS) pros

"The biggest thing about SwiftStack is freedom; it's freedom from vendor lock-in, freedom from one cloud provider, and freedom to scale when you want, how you want, and when you want."

"The graphs are most valuable. They have a lot of graphs and reports that you can run to see what's happening in the background to configure OpenStack Swift."

"The performance is good. It is a secondary storage platform designed for archive and backup, so performance for the right use cases is very good. We have been pretty happy in that regard."

"The scalability is phenomenal. It seems infinite, as long as you put enough storage in place, add enough nodes."

"In terms of the hardware flexibility, with SwiftStack not being a hardware company, I literally buy any hardware that's the least expensive, from any vendor... from a flexibility standpoint, I think it's fantastic. I can go to anybody, anywhere - any vendor - and get my hardware."

"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."

"We have had three years of 100 percent uptime on the system."

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

More SwiftStack [EOL] pros

Cons

"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."

"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."

"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."

"A noticeable area for improvement is the support for object storage."

"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."

"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."

"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."

"In the next release of the solution I would like to see Vormetric native block encryption."

More Everpure FlashArray cons

"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."

"The biggest thing for me, which is a pet peeve of mine, is the integration with the hardware platforms."

"I have heard that there have been latency problems."

"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."

"The interface is not logical. It should be a little simpler."

"The implementation is a little bit complex and should be made easier."

"The solution's monitoring and security features could be improved."

"We would love to see the analytics and ransomware protection extended beyond just file servers to virtual machines, but they have a different product that covers that."

More Nutanix Unified Storage (NUS) cons

"Management UI can be improved and have more functionalities."

"[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. Something where you would have a metadata tagging policy engine and a data mover all built into a single system that would automatically be able to take your data off your primary and put it into an object store in a non-proprietary way - which is key."

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

"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."

"At the moment we are using Erasure coding in an 8+4 setting. What would be nice is if, for some standard configurations like 15+4 and 8+4, there were more versatility so we could, for example, select 8+6, or the like."

"On the controller features, there needs to be a bit more clean up of the user interface."

"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."

"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."

More SwiftStack [EOL] cons

Pricing and Cost Advice

"It is light years beyond anything else with the same price point."

"Price is about the only thing that's wrong with it. A little bit better pricing would be great."

"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."

"The price was more favorable than Dell EMC."

"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."

"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."

"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."

"Because of the SSD, it is cheaper because I am not purchasing so many disks."

More Everpure FlashArray pricing and cost advice

"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."

"Nutanix Unified Storage pricing is reasonable."

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

"The pricing is fair."

"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."

"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."

"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."

"The price of the license is expensive when comparing it to traditional storage."

More Nutanix Unified Storage (NUS) pricing and cost advice

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

"All in, with hardware and everything else - and I hate to say a dollar amount because it's been awhile since I computed it - I know I'm under the $300 to $500 per terabyte mark. I call that my "all in" price, which has replications built in and protections built in."

"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."

"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."

"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."

"One of their advantages of being a commercial open source platform is, for the scale that they offer, the pricing is pretty competitive."

"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."

"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."
