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.

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.
NISHANTPANCHAL - PeerSpot reviewer

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.

Quotes from Members

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

Pros

"The solution has probably reduced my power use substantially."
"It does efficient work of storing data while still delivering the performance that you would normally expect from a higher priced solution."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"I cannot imagine my workflow without Everpure FlashArray because I do not have any other type of storage in use."
"The most valuable feature is the speed of it, as it is much faster than anything that we can get from similar competitors, and the solution helps to simplify storage."
"We have looked at all of the platforms, and to see what Pure was able to do within a PoC environment meant that we never turned back our PoC environment."
"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."
"Firstly, dedupe is the most valuable feature, hands down, and simplifying storage is also a big win overall."
"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."
"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."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
"The deduplication and compression options from NetApp AFF A-Series are good to use for efficient storage capacity."
"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 support is fantastic."
"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."
"The performance of Nutanix Unified Storage (NUS) increased almost 50%."
"We have virtually zero downtime with Nutanix. It updates itself, and we can easily move machines from one cluster to another."
"The Nutanix block files are the most valuable feature."
"Customer service and technical support from Nutanix Unified Storage (NUS) are the major points for us, as they have been very helpful, responsive, and technically strong, resolving a major outage in minutes after responding to our ticket in less than one hour."
"The biggest return on investment for me when using Nutanix Unified Storage (NUS) is the management aspect since it's easier to manage."
"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."
"Based on my experience, I rate Nutanix Unified Storage (NUS) ten out of ten."
"Nutanix Unified Storage (NUS) has definitely helped reduce our total cost of ownership, as centralizing that storage allowed us to eliminate all the other players we had on our premises and NASes, bringing everything under one roof."
 

Cons

"I wish they could collaborate more with the other vendors internally, instead of us opening cases with Cisco, HPE, VMware, etc."
"The file functionality could be better."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"The price is too high."
"The price of this solution could be improved."
"They can also include file services such as NAS shares and CIFS shares. There should be provisioning of the file shares from a unified array."
"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
"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."
"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."
"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."
"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."
"Regarding tech support for NetApp, once the engineer understands our problem, they provide solutions that suit our environment; however, it is essential for the engineer to understand that our environment may differ from standard setups, which can sometimes cause discrepancies in recommendations."
"The solution's ransomware protection could be improved."
"There are still some gaps in the solution's synchronization that could be improved."
"From a management side, the one thing I would prefer is if it were a bit less expensive for smaller enterprises. It's a bit costly. If they provided flexible modules where you could pick and choose features, and only pay for what you use, that would be an improvement."
"For P1 and P2 alerts in the Nutanix Unified Storage (NUS) file share system, including SMB, NFS, objects, or blocks, we must maintain vigilant monitoring. This is crucial because system downtime can disturb the entire ecosystem and impact all applications."
"I would not recommend Nutanix Unified Storage (NUS) to other users or developers because it does not support fiber channel (FC) or NVMe storage, and only supports iSCSI, which I believe is outdated technology in today's market."
"Pain points are just in the management and understanding of how the functions work. As far as updating and day-to-day operations, if my staff is properly trained and we have those proper training sessions, we don't have that many issues. There can be more educational resources from their side."
"I acknowledge that the price of the product can be too high, and it would be beneficial if pricing were more flexible for end users."
"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."
"The graphical user interfaces could benefit from more attention to detail."
 

Pricing and Cost Advice

"There is always room for negotiation."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"There are no licensing fees aside from the support."
"We feel that the pricing is fair and the licensing process was easy for both."
"For us, as the customer, it reduced the price of the management."
"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."
Information not available
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
"The pricing is fair."
"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."
"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."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"The price of the license is expensive when comparing it to traditional storage."
"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."
