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.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

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

"The initial setup was straightforward in the way that it was a database vacuum storage."
"The seamless integration into the public cloud has improved my organization."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"This is the best all-flash storage array on the market."
"From an intangible standpoint the lack of care and feeding is notable and freed up the Storage Team to do other things."
"It makes things ten times easier."
"Deduplication is an excellent feature. I also like the NAS and support."
"Pure Storage FlashArray simplifies maintenance and management with its intuitive GUI, making storage allocation and other processes easy to understand, even for beginners."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"The product's initial setup phase was good."
"The most valuable features of VMAX are its performance and GUI interface."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"It works very well."
"The most valuable features of Nutanix Unified Storage are the unified dashboard and the ease of administration."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"It is more stable and scalable compared to the Windows file server."
"I see that Nutanix helps to reduce the total cost of ownership in general."
"Functionality-wise, we have improved a lot using Nutanix Unified Storage (NUS), as previously we faced significant latency and other related issues."
"What I appreciate most about Nutanix Unified Storage (NUS) is how easy it is to use and how simple it is to create new volumes and containers, and it's pretty quick."
"Nutanix technical support is excellent, with swift responses based on priority."
"The aspect of the product that I like the most is its simplicity."
 

Cons

"The best way to improve Pure Storage FlashArray is the active DR because that can get very confusing, especially when you're trying to test a failover and replicate back; better instructions on how to do that would help because we actually lost an entire volume when we were testing out some stuff as the fingerprint got reinitialized, and when you replicated back, it didn't know about that volume, causing a failure in that process."
"We ran into some issues with the program at first and we had to work around those issues to fix our problems."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"CIFS and SMB Shares cannot be mounted directly."
"We would like to see more cloud support, which we know is coming, although it's not out yet."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"Improvements are needed in both partition recovery and scalability."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"There is room for improvement in the centralized administration."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"I would like to see the integration of artificial intelligence and machine learning technologies. That could definitely be a major breakthrough in providing a unified, seamless experience for end-users. It could reduce costs as well as human effort."
"We have had to deal with some infrastructure and general cluster issues but these issues don't impact storage."
"The solution should keep adding new features to be competitive in the market."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"What's missing in Nutanix Files Storage is the support for multiple intranets or VLANs on the same file from different networks and network devices."
"Nutanix should improve the one-click upgrade. There are a lot of dependencies on third-party licenses and HP hardware we use internally. The one-click upgrade fails sometimes."
"The solution should include more protocols to access data."
"I really want some AI or even basic AI to be included in the Nutanix Unified Storage (NUS) license."
 

Pricing and Cost Advice

"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"I would rate it a seven out of ten for pricing. It could be improved."
"We do not incur additional costs beyond the licensing fee."
"Pricing is very competitive, and it's better than other competitors."
"We purchased a license to use this solution and we pay for the storage ourselves."
"It is not a cheap product."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."
"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."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
"The solution is highly-priced."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"The price of the license is expensive when comparing it to traditional storage."
"It is very good. It is much more competitive than a dedicated storage platform."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
