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.

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

"The support from Pure Storage Flash Array is amazing."
"We saw a vast improvement when we switched over to using the Pure Storage model over the XtremIO."
"We find the ease of usability and setup valuable."
"Pure Storage FlashArray offers numerous valuable features, such as low latency and high throughput."
"The initial setup was really straight forward."
"Technical support is good."
"Service and support is phenomenal."
"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."
"Cohesity SmartFiles aids in data management with features like full-text search through indexed documents."
"After working with other Nutanix solutions, I can say that everything has a purpose, and it is pretty bulletproof."
"Nutanix technical support is excellent, with swift responses based on priority."
"Nutanix Unified Storage (NUS) can meet any storage need that a company has, such as traditional block storage for NFS or virtualization, and it can deliver a file solution for different kinds of needs of a company, and even objects for backup, for logs, for data lakes, for image repositories."
"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."
"What I appreciate most about Nutanix Unified Storage (NUS) is the efficiency in terms of storage capacity and reuse."
"Nutanix has excellent product documentation available on their portals, written in simple, easy-to-understand language."
"I appreciate its storage licensing model, as it offers flexibility."
"Nutanix Files is a complete solution in the Telco Machine and offers a host of benefits, including easy management, upgrading, and analytics of new data."
 

Cons

"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"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."
"CIFS and SMB Shares cannot be mounted directly."
"I would love for them to have a hyper-converged solution."
"The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"Users must remember that running DataProtect and files on the same cluster could threaten access if there is a platform failure. It's not suitable for applications needing high I/O or low latency."
"While they are good and they do work, some of the snapshotting and tiering features are not as simple to set up as they could be."
"The interface is not logical. It should be a little simpler."
"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."
"One area for improvement I noticed while using Nutanix Unified Storage (NUS) is expanding advanced analytics and predictive capacity planning capabilities to help administrators make even better long-term storage decisions."
"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."
"It has a price barrier. It's not for everyone."
"The product needs to work a bit more on its ransomware detection capabilities."
"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."
 

Pricing and Cost Advice

"We have seen a reduction in TCO."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"The price of the solution is not expensive."
"Our costs are around $100,000."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
Information not available
"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."
"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."
"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."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"It is not too high for what we are using."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
