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 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.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

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

Pros

"Provides fast access and is user-friendly."
"It simplifies storage."
"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 product cheaper compared to other solutions concerning the technology that they are using."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"It has good stability for our company."
"It's just very easy for general block storage."
"The most valuable features are the ease of use and support."
"Nutanix Objects is reliable."
"The benefit that our clients see is the security of the whole Nutanix platform where they have simplified usage."
"The best features of Nutanix Unified Storage (NUS) are its simplified management, scale, and performance; data services can be easily consolidated, which help in disaster recovery services, replication, and reducing complexity and costs associated with this architecture."
"The features I appreciate the most about Nutanix Unified Storage (NUS) are the compatibility with the market."
"For customer service and technical support, I would rate them a nine out of ten."
"Since migrating to Nutanix, we have not lost any data despite node failures due to its high availability and redundancy factor."
"One of the best features of the Nutanix Unified Storage (NUS) is that I find everything, all the solutions, in one single box; if you look into Nutanix, the HCI plus whatever storage is required as part of the requirements, such as if applications are hosted on Kubernetes or container platforms requiring S3, NFS, or any other protocol, we can access everything from a single system, eliminating the need to manage multiple systems and different storage in the data center, as one system from one OEM provides everything."
"My overall rating for Nutanix Unified Storage (NUS) would be nine out of ten, as I have no complaints."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"Quest QoreStor is very stable compared to our previous solution."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Quest QoreStor definitely saved us money."
 

Cons

"It was a little costly."
"They should work on their upgrades, they're not smooth."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"Scalability is not an easy option for Pure Storage, so you have to be very careful when you are getting that product for you."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."
"Based on my experience with various technologies like EMC, NetApp, and Pure Storage, one area for improvement is compliance certifications. NetApp excels in this area, particularly in the American Army or defense sector, where NetApp has approval, whereas others are striving to achieve the same. NetApp also delivers security, ransomware protection, and scale-up capabilities more effectively."
"We haven't seen ROI."
"The GUI is not user-friendly for new users and has room for improvement."
"The documentation on the support site needs to be improved."
"For me, personally, it's a little bit slow because there's so much stuff in the underlying layers that even after talking with Nutanix support, I couldn't really grasp it."
"The analytics part of Nutanix Unified Storage is too big and should be made smaller and less resource-hungry."
"There are some processes, like if I like to change the data storage to another place, I have to use CLI, and I don't like it since I believe that it could have been simpler in GUI."
"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."
"It has a price barrier. It's not for everyone."
"With all of the Nutanix equipment, the licensing is expensive. We operate in the enterprise space, but we're a midsized company. At times, the price tag is a little bit shocking for a company with only 35 employees."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The ransomware protection of QoreStor could use improvement."
"The air gap feature is something I'd really like to see in QoreStor."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
 

Pricing and Cost Advice

"There are no licensing fees or other costs."
"The solution is expensive."
"We have seen a reduction in total cost of ownership."
"We feel that the pricing is fair and the licensing process was easy for both."
"Our costs are around $100,000."
"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."
"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."
"The pricing is a bit too high."
"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."
"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."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"It is competitive with other vendors, but you get more for your dollars. It is fairly priced, but not cheap."
"In my opinion, the product is fairly priced."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
