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.

Overall functions well, stable, but technical support could improve
Veritas Access Appliance installation is user-friendly. You need network team cooperation for the setup of the cluster configuration. The Veritas Access Appliance initial configuration process is broken into two phases. The first phase requires that you perform each configuration step on each individual node. You should have two terminal windows open during the first phase, each logged into one of the nodes. During the second phase of the initial configuration, you should only perform the steps on one of the nodes. When you start the second phase of the initial configuration, close one of the terminal windows and continue doing the steps on only one of the nodes. When you initiate the cluster configuration, the settings that you configured on the current node are copied over to the second node in a one-time synchronization event.

Quotes from Members

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

Pros

"It is easy to deploy and it's all-flash, so it's very fast."
"We have looked at all of the platforms, and to see what Pure was able to do within a PoC environment meant that we never turned back our PoC environment."
"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."
"I like its speed. It has all the features that I need."
"Its array houses our entire production environment."
"It's actually very stable"
"Having an intuitive user interface to get things running is great."
"From an investment standpoint, the support staff I require for it is greatly reduced, so I don't have the in-depth requirements that I had on other products."
"It is more stable and scalable compared to the Windows file server."
"In the beginning, when they sold us Nutanix Unified Storage (NUS), they told us the performance would be 30%. Then we came to them and said, 'You are a liar. It's not 30%, it's 800% increase.'"
"I strongly recommend Nutanix Unified Storage (NUS) to all users."
"I see that Nutanix helps to reduce the total cost of ownership in general."
"The product's initial setup phase was simple."
"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 availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."
"Overall, this is a good product and I recommend it."
"Veritas Access Appliance is doing everything for us, such as system recovery, backup, and cloud data protection."
"It is a very stable program."
"It is a very stable program."
"Overall the solution works well."
 

Cons

"I would like to see data tiering to AWS."
"There are a lot of things to improve."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"We have not seen a reduction in our TCO nor have we seen ROI."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Self-backup is the only feature lacking in this solution."
"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"Nutanix needs to improve their cybersecurity options at the storage level."
"Pain points are just in the management and understanding of how the functions work."
"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."
"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."
"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."
"Pain points are just in the management and understanding of how the functions work. As far as updating and day-to-day operations, if my staff is properly trained and we have those proper training sessions, we don't have that many issues. There can be more educational resources from their side."
"The solution's monitoring and security features could be improved."
"I think Nutanix Unified Storage (NUS) can be improved with integration with vendors other than VMware or Dell, seeking more integrations with other storage vendors."
"The Veritas support for Access Appliance could improve. They are a pioneer in the industry, and they provide an enterprise-level solution. However, when comparing the storage, they can't compete with the NetBackup solution."
"I would like to see more platforms added."
"The Veritas support for Access Appliance could improve. They are a pioneer in the industry, and they provide an enterprise-level solution; however, when comparing the storage, they can't compete with the NetBackup solution."
"It currently only supports five of the cloud platforms."
 

Pricing and Cost Advice

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"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."
"The price, in general, is around $100,000, however, I know it costs more."
"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"The pricing of Pure Storage FlashArray is reasonable."
"The price is reasonable."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"Nutanix Unified Storage was cheaper than other solutions we evaluated."
"Its pricing is good to okay. It is not super inexpensive, but it is still competitive. Everything could always be lower."
"Nutanix Unified Storage isn't expensive."
"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 licensing model the tool has is cheaper than an HCI storage solution."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"I'm happy with the cost and licensing because I don't have big volumes."
"The solution is not expensive compared to other storage solutions."
