Technical Lead at Wipro Limited
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 storage has simplified private cloud operations and delivers strong security and ROI
Regarding areas for improvement, I think Data Lens could be enhanced from Nutanix's side, but it has been a long time since I logged into that console, so I do not remember much. It is a SaaS-based offering on the Nutanix portal. It is not something you deploy on-premises; it is not on-prem access. You connect your cluster to the SaaS-based Nutanix and then access the Lens console. I need to check it since it has been almost two or three months since I logged in. Nutanix Enterprise AI actually needs to improve a lot if I compare it with any other product such as NVIDIA and other offerings in the market. Nutanix Enterprise AI still requires a lot of work. I did not check that in much detail technically, but whatever I thoroughly checked, it still lags behind in many features. When it comes to AI-related features, I think the ecosystem of Nutanix is not as big as NVIDIA because NVIDIA has its own inferencing system and model training platform such as NeMo, NeMoTron, and others. Nutanix does not have such things. It can be built using NVIDIA CUDA libraries, but what I saw when I was testing the product is that you can run NVIDIA NeMo and PyTorch and two other things, but as a software, Nutanix does not have an end-to-end platform. That is something Nutanix should focus on.

Quotes from Members

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

Pros

"I like its speed. It has all the features that I need."
"We noticed a dramatic increase in application performance when moving it from NetApp to Pure Storage."
"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."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"The sales and executive support have been outstanding compared to the rest of the market... My upgrade paths have been simple on the Pure... It's a lot simpler to implement and a lot simpler to manage."
"It has improved the way our organization functions by improving the resilience of our infrastructure by quite a bit."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"Firstly, dedupe is the most valuable feature, hands down, and simplifying storage is also a big win overall."
"It works very well."
"The product's initial setup phase was good."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"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 most valuable features of VMAX are its performance and GUI interface."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"The solution's most valuable feature is the Prism Central centralized management console."
"The availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."
"It is more stable and scalable compared to the Windows file server."
"I like its interface. It is very interactive and simple to use."
"Nutanix's analytics provide better insights into all of our files."
"We can utilize mixed storage block-sized objects and combine various databases within a unified interface."
"Since I started working with Nutanix, the only consistent thing I can identify as key is simplicity."
"The scalability, data redundancy, and security are valuable."
 

Cons

"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."
"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"Some of the issues are that it's probably not on a par with other large storage enterprise type products."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"Improvements are needed in both partition recovery and scalability."
"There is room for improvement in the centralized administration."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"There is a feature in the product called Data Lens, and I can elaborate on its maturity. I believe this Data Lens feature could be enhanced from Nutanix's side."
"The solution should include more protocols to access data."
"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."
"The current hardware is not as dense as it could be. In our deployment, we have 2 PB per site, and we have to have 24 nodes. That's a lot of cabling and network ports that we use up. More dense nodes would be better."
"There is an occasional language barrier between some of the technicians, which can be challenging; however, that doesn't prevent us from being assisted, as they can remote in and use Pulse to view our cluster and gather logs and reports."
"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."
"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."
 

Pricing and Cost Advice

"The solution is expensive."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"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."
"Our costs are around $100,000."
"The price was more favorable than Dell EMC."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"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."
"The pricing is a bit too high."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
"We are Nutanix partners, so it is pretty good. With the free terabyte that comes with the Nutanix clusters, we have started to build proposals for the clients. The price adjustment with the new policy of Nutanix Unified Storages seems attractive. Let us see if it has results."
"The pricing is fair."
"The solution's pricing is fair."
"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."
"From what I hear from the management, Nutanix Unified Storage has comparatively decent pricing."
