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.

Provides seamless research data management with effortless setup
From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS. Sometimes we go with Weka or other solutions due to this need, so it should have more IO capacity when there is a demand. More performance is needed specifically in the IO area.
Amarnath Charugundla - PeerSpot reviewer
System Engineer at Tata Consultancy
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 stability is perfect. The reliability is 100% and the latency is always lower than 1 millisecond."
"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."
"It upgrades in place which means we'll be using it well into the future."
"It is easy to deploy and it's all-flash, so it's very fast."
"The availability and ease of use are the big features."
"Manageability is its most valuable feature; it is simplified storage, as we don't have to maintain or administer it on a daily basis, which is good, and we can depend on the solution's ability to phone home and leverage the built-in support function of the product."
"Even if it costs a little bit more, you do get more for what you pay."
"The most valuable feature is it never goes down. We can expand and create volumes."
"I rate the stability of Amazon FSx ten out of ten."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"The shared storage capability is highly valuable."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"The product's benefits stem from the ease of use and management it offers to its users."
"It is more stable and scalable compared to the Windows file server."
"The scalability, data redundancy, and security are valuable."
"The most valuable features of Nutanix Unified Storage are the unified dashboard and the ease of administration."
"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."
"For customer service and technical support, I would rate them a nine out of ten."
"Offers high performance, full control, and strong security for mission-critical workloads."
"The solution is simple and robust."
 

Cons

"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"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 love for them to have a hyper-converged solution."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"They could improve the price."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"I would love for them to have a hyper-converged solution."
"I would prefer that they lower their pricing."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"The problem is that we need to invest a lot of money to get AI, and therefore, we are not going to purchase AI right now."
"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."
"The CVM consumes more memory and CPU, as it will be allocated a minimum of 32 GB. For a large data store, they are unnecessarily consuming extra resources through the built-in CVM."
"The product does not offer one console."
"In summary for improvements, I would say stay on the integration path, keep those integrations heavy, and let us use the software and technologies with everybody."
"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"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."
 

Pricing and Cost Advice

"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"The price of the solution is not expensive."
"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"The licensing currently works based on a software license. If we have files, volumes, and other licenses combined, that would be more valuable. I don't want to go for a separate license for files and a separate license for volumes. We have unified storage, so the licensing should also be unified. That would be helpful."
"The price of the license is expensive when comparing it to traditional storage."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"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 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."
"The solution’s pricing could be cheaper."
"The product has an annual licensing fee."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
