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.

A robust solution with good performance and support
This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

Hyper-converged storage has improved performance and now supports high redundancy for our VMs
Nutanix Cloud Infrastructure (NCI) was transparent because we were on a regular infrastructure before. We went on NCI and were able to improve performance, but it did not really change how things worked. The performance was really better for applications and access times to the data. I regularly looked at the analytics to see what was going on in my servers and what it was saying to optimize performance. It was pretty interesting because it could analyze and give insights on how to get things working better. In the latest versions, the Prism interface has been replaced by Prism Central. This requires another machine to be deployed to manage the servers.

Quotes from Members

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

Pros

"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."
"They have really good baked in analytics to show you trends for growth history, so it does help with future planning for data growth."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"The reliability is very good."
"The amount of throughput that we're getting is really nice."
"The ease of use is the solution's most valuable aspect; it's very user-friendly, and the security on the product is very good."
"Implementing this solution has been a very good decision for our in-house data center."
"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."
"Nutanix provides the best migration to cloud platform, helping our company aggregate most of our workloads into a centralized platform, improving the efficiency for the IT team and infrastructure resources, and throughout the journey providing the best support we have ever had from solution providers and vendors, adding big value to our operations and supporting our SLAs with our customers."
"The initial setup is straightforward."
"Nutanix Acropolis AOS is affordable, it has good value."
"A lot of features are there, but for us, on the server administration side, creating a clone of the VM is valuable because many times, we have to deploy security patches. For deploying these patches, it helps to have a clone so that if something goes wrong, we can discard that VM and put back the clone VM. That is a very cool feature."
"SRM capabilities for replication have been proven reliable and very useful for our organization."
"If you want to build a hybrid cloud, and have a good balance between cost and performance, then Nutanix is good option."
"The best feature of Nutanix Acropolis AOS is the central management of all of our resources. Additionally, it is easy to use"
"The administration console, automation, and the first cluster are all valuable features."
 

Cons

"I would appreciate improvements on daily health checks."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"Pure Storage's logs could provide more visibility to the end-user. The logging algorithms are different from those of other vendors. For example, Cisco's logs provide extensive troubleshooting data, whereas Pure Storage logs offer limited information. We have to contact support to get more information."
"When creating a support case, visibility should be extended to others involved in assisting."
"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."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"The interface is not user-friendly so the ease of use could be improved."
"The reporting mechanisms need improvement."
"It was complex, as we needed to move from a Xen environment to Acropolis. The migration process was not easy."
"Make it easier to manage."
"With some projects that we are deploying, there are errors that arise when adding nodes."
"We feel that the cost for capacity is still more expensive compared to other solutions."
"Nutanix Cloud Infrastructure's LTS version needs to be more reliable."
"We'd like to have more resource management."
"If they can simplify the software slightly for the installation, that would make all the difference."
"Sometimes, I had to install it twice to place the solution."
 

Pricing and Cost Advice

"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"Cost-wise, it's been very effective."
"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."
"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"The cost has room for improvement."
"Pure Storage has not helped to reduce our HANA licensing costs."
"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."
"If you are cost-sensitive then this solution is not for you."
"The price of the solution is high."
"Able to grow with smaller, more linear increments of investment"
"The license is quite clear to me. It's much clearer than what we had with our previous virtualization environment. The licensing is not complex to understand."
"The pricing is quite good in comparison with HPE SimpliVity, Nutanix Scale, and even traditional architecture."
"It is less expensive than the VMware alternative."
"Many of my customers have issues with Acropolis' licensing model because they are charging the customers based on two things— the CPUs and the capacity in the solid stack disk — and that's a problem. Nutanix's competitors are not licensing that layer, so this is something that they should change. They should abandon this licensing model because it's too complex. Technical support is bundled with the subscription."
"Nutanix Acropolis AOS price includes no additional costs for features."
"Nutanix Acropolis AOS is affordable, it has good value. The final price depends a lot on the hardware used, it's an appliance in the end. Whether you use HPE as the hardware vendor or Supermicro as the hardware vendor, it really depends on what hardware is used which is the main cost."
