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

"We noticed a dramatic increase in application performance when moving it from NetApp to Pure Storage."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"I am very satisfied with this solution and I would recommend it to others."
"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."
"You can get your storage access within two minutes, which is great, because it is a lot quicker for our team to get the servers up and running."
"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."
"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"Redundancy and availability are valuable. We have several nodes, so it stays up, and there is redundancy. Then there is availability."
"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."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"I like its interface. It is very interactive and simple to use."
"The access to that file storage shared folder is very good compared to other storage, and the storage access speed is very fast for Nutanix Unified Storage (NUS)."
"My experience with using Nutanix Unified Storage (NUS) for data-intensive workloads is that we have many SQL Servers and they perform much better than they did when we used hybrid converged previously."
"The solution's most valuable feature is the Prism Central centralized management console."
"I like Nutanix Prism Central. The primary benefit is that we can manage everything from the same page."
"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."
"QoreStor has helped us to reduce our backup storage requirements on-premises, and we've been using the same devices for quite a while, so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution."
"Quest QoreStor definitely saved us money."
"Quest QoreStor is very stable compared to our previous solution."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
 

Cons

"I would like to see more cloud integration."
"I think replication is one area that still needs improvement."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"We would like to see more cloud support, which we know is coming, although it's not out yet."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"A centralized file share permissions console might be useful for Nutanix Unified Storage (NUS). Getting in and directly managing permissions instead of using the snap-in from Windows itself might be something to consider, but that's a small thing."
"Areas for improvement in Nutanix Unified Storage (NUS) include more redundancy to ensure no data loss, and balancing the workloads is very important to maintain managed workloads throughout the year."
"The implementation is a little bit complex and should be made easier."
"The only thing I would say is missing for us it is FTP protocol compatibility."
"The management is pretty clunky, in my opinion. It could be a little bit better."
"The integration feature with Nutanix Unified Storage (NUS) could be improved, maybe into a more stabilized version."
"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."
"I really want some AI or even basic AI to be included in the Nutanix Unified Storage (NUS) license."
"The ransomware protection of QoreStor could use improvement."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"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."
"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."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable."
"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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
 

Pricing and Cost Advice

"It could always be lower, but it's okay."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"Pure has been flexible with us on the pricing models."
"Its price is almost double than any other flash storage solution."
"The licensing is $100,000."
"It's expensive, but you get what you pay for."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"The pricing is a bit too high."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"I hope that it will stay the way it is. We have seen the changes in VMware and what happened to them. I have heard that Nutanix will raise the prices, but I hope that they will not do that."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
"The solution's pricing is fair."
"The solution's pricing is better compared to other products."
"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."
"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
