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.

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"The best features Everpure FlashArray offers are its ease of setup and incredible performance, which is better than most other software or hardware that we have used."
"It has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."
"Do it. I have zero reservations about recommending Pure to anyone who is looking for some really good all-flash."
"We chose Pure Storage primarily because of its combination of performance and ease of use."
"Technical support is good."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"This improves our organization because we can just set it up and we forget about it, everything works, and we do not need to worry about storage or bandwidth issues."
"What I found most valuable in Nutanix Files Storage is its high availability and ability to scale out with many VMs."
"The solution is very easy to manage."
"Nutanix Unified Storage is a stable solution that provides good storage and efficiency."
"The most valuable feature is that it is highly available, solving the pain-point of delaying updates to Windows-based file servers during production hours. And then the second one would be ransomware protection and analytics. It gives you great visibility and protection on your file shares that are otherwise the most common sources of vulnerabilities."
"Nutanix has the best customer support in town."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"We transitioned from a three-tier architecture to Nutanix Unified Storage (NUS). With the Files offering out of Nutanix Unified Storage (NUS), we were able to migrate those shares with a smaller footprint."
"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."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"I would like to see them lower the costs."
"The solution needs an integrated NAS platform, file platform."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"In Pure Storage FlashArray, the area with room for improvement is local MFA login."
"Storage. There could be better storage."
"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The solution needs to be more open to integration with other vendors. Sometimes, we struggle with the support process. Our skilled engineers must explain our problems to everyone, even though we've already done preliminary investigations. The support team follows standard procedures, which can be painful. We're not a small customer, especially in the life sciences sector, so we'd appreciate more specialized support. I've heard Nutanix Unified Storage has teams dedicated to life sciences and healthcare; we should be part of that."
"A more consistent flow of information would improve the solution, as I've noticed some inconsistencies, mostly stemming from the coordination between the hardware vendor and Nutanix."
"The solution should keep adding new features to be competitive in the market."
"The initial setup is a little bit complex."
"Unified Storage failed to fulfill our object storage requirements."
"One thing I'd appreciate is having a desktop application similar to what VMware offered."
"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."
"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."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"The price is very reasonable when compared to other solutions."
"I don't know the exact cost but it's around $1,000."
"The price of Pure Storage FlashArray is expensive."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"Nutanix Unified Storage isn't expensive."
"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."
"It is very good. It is much more competitive than a dedicated storage platform."
"The pricing is a bit too high."
"It's not the cheapest solution. It's in line with other solutions, but it offers features that the competitors don't have at any price point, especially with regard to analytics and ransomware prevention. No one else has any sort of object-based storage available. Nutanix Unified Storage is a lot more feature-rich. This is a situation where you get what you pay for."
"I'm happy with the cost and licensing because I don't have big volumes."
"The product is pricey."
"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
