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.

Cost-efficient, highly scalable, and installable on different types of hardware
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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"The performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."
"The performance is great."
"It is noticeably easier to manage than other appliances that we have."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"The compression rate is one of the most valuable features of Pure Storage FlashArray. Additionally, it is all-flash storage with excellent IOPS, and hardware failures are very less."
"After installing Pure, the processes that would take 40 minutes to two hours to complete are now done in five minutes."
"You get what you pay for; it is expensive, but it really works, so I would really recommend using Pure Storage."
"The solution is very reliable."
"The solution is stable and extremely easy to calibrate."
"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."
"We migrated over to Nutanix and saw an immediate improvement in the performance."
"Overall, it's a good product."
"Whenever we have some necessity in terms of capacity and expansion of infrastructure, it's like a Lego system where they can just place in some more nodes and our needs are met."
"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"The solution is very easy to manage."
"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."
"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Quest QoreStor definitely saved us money."
 

Cons

"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"We haven't seen ROI."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."
"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."
"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."
"The only thing I would say is missing for us is FTP protocol compatibility."
"There are still some gaps in the solution's synchronization that could be improved."
"Unified Storage failed to fulfill our object storage requirements."
"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."
"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."
"It is challenging to configure access control settings."
"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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"The ransomware protection of QoreStor could use improvement."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
 

Pricing and Cost Advice

"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"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."
"We are finding the TCO of flash to be lower than SSD implementations."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"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."
"There is always room for negotiation."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The price was more favorable than Dell EMC."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"Licensing-wise, I have no complaints. Their license is pretty simple and easy. It gives us everything we need, so I have no complaints about licensing."
"The pricing is a bit too high."
"Nutanix Unified Storage isn't expensive."
"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."
"I'm happy with the cost and licensing because I don't have big volumes."
"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."
"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."
"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."
