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

"The solution has probably reduced my power use substantially."
"While all these products have their own uses, Pure Storage FlashArray is in a market of its own."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"This solution has improved my organization because it has good performance."
"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."
"The deduplication and compression rates are beyond impressive."
"Regarding downtime issues, we haven't had downtime in generations, and everything is going very well."
"The interface is quite simple. It is very good. It is easy to configure. It also has a powerful CLI."
"Currently, the most valuable aspect of our Nutanix implementation is its file storage functionality."
"The features I appreciate the most about Nutanix Unified Storage (NUS) are the compatibility with the market."
"The most valuable features of Nutanix Unified Storage are the unified dashboard and the ease of administration."
"The most valuable feature is the easy interface."
"The customer service executives of all Nutanix products are active and responsive."
"The feature I like most about Nutanix Unified Storage (NUS) is the ability to optimize storage spaces."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"It has a price barrier. It's not for everyone."
"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."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."
"The solution should keep adding new features to be competitive in the market."
"I would not recommend Nutanix Unified Storage (NUS) to other users or developers because it does not support fiber channel (FC) or NVMe storage, and only supports iSCSI, which I believe is outdated technology in today's market."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"It functions as intended. We don't have any real requests or improvements. We're primarily focused on protecting our data. However, we use Varonis, so it would be nice to have better integration with that."
"Licensing cost of Nutanix Unified Storage (NUS) is higher for smaller organizations."
"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

"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"Pure Storage has not helped to reduce our HANA licensing costs."
"We do not incur additional costs beyond the licensing fee."
"We feel that the pricing is fair and the licensing process was easy for both."
"All storage is expensive so any price improvement would help."
"We have seen a reduction in TCO."
"It's priced higher than the market."
"For clients running Nutanix, the licensing cost for Files is a small add-on cost."
"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."
"I'm happy with the cost and licensing because I don't have big volumes."
"Nutanix Unified Storage isn't expensive."
"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."
"The licensing model the tool has is cheaper than an HCI storage solution."
"The pricing of Nutanix is generally higher compared to other vendors, which is a common observation, but it provides value through its support and features offered to customers."
"Nutanix Unified Storage pricing is reasonable."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
