Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Gives us the foundation to grow efficiently
We're a manufacturer. All of our ERP software is dependent upon fast performance and connection to this hardware. So when there was an issue years ago when something was wrong or slow, that prompted us to say, "Can we check storage? Can we check the network?" Ever since we've gone up to all-flash FAS systems, there's never any questions about performance when it comes to storage. There's been a huge leap from spinning disks to SSDs. I'm hoping with the next update, we'll go to NVMe and we'll have similar experiences. Last year, we refreshed the SAN at our headquarters. We signed a Keystone agreement with the ability to pay for storage as a service at an excellent price point yet still have the hardware on-prem. I manage the hardware, and, for me, it's the best of both worlds. We've just come up with a situation where, finally, after some time, we're going to need to buy some additional storage. In previous situations like this, it usually meant the purchase of an additional shelf at a large price. Now we have Keystone, and we're locked in at that price per tebibyte. We just have to say that we want to add 25 tebibytes and they take care of it. It's worked out really well. We work ISO 27001 certified. Since I manage the enterprise storage, we use SnapMirror, and we're currently using Veeam for backups. Thanks to what this tool provides, we are able to get through that portion of our certification without a problem. No changes, no rectifying. It's very slick. Our company's goals include maintaining a level of consistency. We're never going to be on the bleeding edge. We're never going to have the super fastest abilities. We want something that works, is easier for us to manage, and has a better growth path. For us, in the past, in the need for additional disk space, if we didn't do the sizing right in the first place, buying additional disks was incredibly expensive. Now, with Keystone, that's no longer an issue, and that's what we like.

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.

Quotes from Members

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

Pros

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"Overall stability is very good. It is a very stable solution."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The amazing thing is that whenever we have come up with an issue where we need to get something done, and it wasn't necessarily available, they could do things for us, usually within the next revision of the software."
"NetApp helps us get the fastest output."
"We've reduced downtime. Without all of NetApp's benefits, we would have had to reconfigure parts of storage that would have required downtime. We have dramatically reduced our downtime through successive generations of NetApp, allowing us to get Five 9s availability."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
"MetroCluster is the best product on the market. It synchronizes the storage. NetApp's update packages are a huge advantage because the firmware and server updates are in one package."
"NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive."
"NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."
"NetApp support is fantastic."
"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."
"The benefit for our customers is cost effectiveness. The customer is spending substantial money refreshing NetApp storage. We identified a use case from a NAS point of view. Using Nutanix Unified Storage (NUS) helps in reducing costs, as they are not spending a dedicated cost for storage procurement."
"It is more stable and scalable compared to the Windows file server."
"The most valuable features of the solution are replication and backup and our company needs a tool to help us with disaster recovery and the security of our data."
"The best Nutanix Unified Storage features are its recovery and data speeds. It has resolved the issue of accessing information quickly."
"Nutanix Unified Storage (NUS) is very scalable."
"Nutanix Unified Storage is easy for end users to access. They can use it like any other drive on their systems. We have mapped it in the user system so they can scan files and store them. They can use it just like an Android drive."
"The feature that I find most useful in Nutanix Unified Storage (NUS) is the integration with Nutanix Move where you can seamlessly integrate it into your storage."
 

Cons

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"I'd like to see the product implement active replication for vehicles such as VMware."
"In terms of what needs improvement, the dashboard and management could be simplified."
"We need better data deduplication."
"There is room for improvement in the pricing of the product."
"There are some challenges with data encryption and reduction."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"I really don't have a lot of complaints. In the past, there were issues, however, they've really done a great job of reaching out."
"Pricing could always be lower."
"The solution's ransomware protection could be improved."
"We have several problems with the limitations of NetApp systems in terms of volume shares. We have a brick in a 700 or a controller, and we sometimes make small volumes, but Kubernetes container volumes don't allow us."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
"NetApp is shifting to the cloud and adopting AI, but it is not improving its core technology to deliver faster storage. We're still waiting to see if it improves speed with solutions like the 90 series."
"It would be helpful if our partner organized a yearly session with my team to discuss the new feature sets on our current solutions and other ways NetApp can help us. Perhaps we are missing some information to help us make the right decision."
"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."
"The pricing can be quite high."
"The GUI is easy to use, but it's complex to do tasks from the command line. That is one way they could simplify things for the engineers. People tend to use a graphical interface more than the command line interface. If anything goes wrong, we need to do troubleshooting from the CLI. It would be nice if there were more ways to fix issues within the GUI."
"While they are good and they do work, some of the snapshotting and tiering features are not as simple to set up as they could be."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."
"The GUI is not user-friendly for new users and has room for improvement."
"The licensing terms are restrictive, as they go by terabyte cost."
"There is potential to push this product more since it's not common in the market. They could increase their marketing efforts."
 

Pricing and Cost Advice

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"With VMware, we pay $300,000 annually."
"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"The product is expensive."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
Information not available
"In the manufacturing industry, we operate under very lean principles where costs are heavily scrutinized. There was some initial hesitation, but the performance we've experienced since switching to the Nutanix platform, along with the peace of mind from having confidence in our platform to not give us issues that keep us up at night, has smoothed over much of that scrutiny."
"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."
"It is very good. It is much more competitive than a dedicated storage platform."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"I'm happy with the cost and licensing because I don't have big volumes."
"The solution's pricing is better compared to other products."
"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."
"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."
