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.

Enables seamless file distribution while benefiting from scalability but could use simplified implementation
IBM Storage Fusion is used in telecoms. It is a file center that receives and shares files. It is also used for writing the CDR zone on the storage, since it offers a cost-effective solution for large-scale storage needs in a telecom setup The deployment of Storage Fusion has been new for us in…

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

"They are quite responsive and our local team was pretty good."
"At this point, I don't know anything that they could provide in a better way."
"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."
"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"Processes that used to take 40 minutes to two hours can be completed in five minutes."
"From the first test that we have conducted, we are very satisfied with this solution."
"Fusion provides the ability to install the secret server and distribute files; it serves as a black box where tickets are opened only if issues arise, reducing frequent upgrade problems."
"Nutanix Unified Storage (NUS) is very fast in terms of migration and data access with respect to VM, OS, and storage, experiencing a 30% faster performance compared to VMware."
"The performance has been very good."
"Nutanix Volumes is a perfectly stable product."
"The Nutanix block files are the most valuable feature."
"It is more stable and scalable compared to the Windows file server."
"My company has benefitted from Nutanix Unified Storage because we have everything in a centralized place. With Prism Central, we can go to the console files and do what we have to do."
"I see that Nutanix helps to reduce the total cost of ownership in general."
"The reliability and stability of Nutanix Unified Storage (NUS) is good, and the disaster recovery component is something impressive for this product."
 

Cons

"The file functionality could be better."
"The price of Pure Storage FlashArray could be better."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"The solution is not cheap."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"The technical support is okay, but could be improved."
"The implementation is complex, especially when using custom servers."
"The solution is very expensive."
"Nutanix Unified Storage (NUS) needs improvement, particularly for firmware upgrades, as sometimes updates take a whole day and it can be unclear whether the issue is with Nutanix Unified Storage (NUS) or the hardware, requiring us to reconfigure everything, which is a main point we want consolidated into one solution."
"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."
"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."
"The product does not offer one console."
"Its interface is very simplistic. It is a good thing for people because of the ease of use, but at times, I find it too simplistic. It is hard to find advanced options. They should eventually expand it and provide additional drop-down lists or menus with advanced feature sets."
"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."
 

Pricing and Cost Advice

"The solution is expensive."
"The price, in general, is around $100,000, however, I know it costs more."
"Pure Storage has not helped to reduce our HANA licensing costs."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"It is a cheaper solution."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
Information not available
"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."
"The solution’s pricing could be cheaper."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
"The pricing is fair."
"The product has an annual licensing fee."
"It is very good. It is much more competitive than a dedicated storage platform."
"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."
