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.

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies
IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

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

"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"Their REST API is wonderful, well-documented, and easy to use."
"We chose Pure Storage primarily because of its combination of performance and ease of use."
"The deduplication and compression meet all of our system requirements."
"Even if it costs a little bit more, you do get more for what you pay."
"My advice to others looking into using Everpure FlashArray is that it's a really good product, especially if your main purpose is to get high speed with more redundancy and reliability; then go for it."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"We are using it for monitoring all of our storage."
"It is a scalable solution."
"It is incredibly scalable; you can add more storage to it, add more file sets, and add it to more servers, making it a robust product that should be able to expand with us."
"Technical support has been very helpful, and they provide us with pretty good solutions that we can implement moving forward."
"There is nothing else that even compares to Spectrum Scale."
"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."
"The high performance of the solution is its most valuable aspect; if you compare it to other storage solutions, it is much better."
"Over the past five or ten years, IBM has developed this solution and it has improved a lot."
"The most valuable feature is Move, which allows you to migrate virtual machines from VM to AHV."
"SRM capabilities for replication have been proven reliable and very useful for our organization."
"We are suggesting Nutanix to the management because of scalability and time efficiency."
"We have been running Nutanix since 2019 and it has been a day and night difference from our old infrastructure."
"Hyperconvergence gives a faster implementation than the standard solutions, and a high density architecture."
"We can test even the most storage-performance-hungry workloads on our Nutanix blocks."
"With the simplicity of the deployment and the one-click operations over the cluster, Nutanix Acropolis AOS is a good solution."
"In terms of stability and performance, Acropolis is excellent."
 

Cons

"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"There was some complexity in the initial setup."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"I want to improve the overall service level of the solution."
"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."
"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."
"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."
"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"We do not feel as a company that the product can grow with us anymore, so we are not going to use it anymore."
"The biggest problem is that it is not able to provide block storage."
"There can be improvements in fault tolerance and making erasure coding faster."
"If your server virtualization, network and storage teams operate in silos and are constantly at war with each other, then HCI is probably not for you at this time."
"Nutanix needs more development on DRC solutions embedded in Acropolis."
"We could always use a performance upgrade, or simplified management."
"When moving a critical infrastructure from a physical machine to Nutanix Cloud Infrastructure (NCI), we currently have to use a third-party tool to convert the physical machine to a VM."
"Lacks sufficient integration with other vendors and public clouds."
"There is a feature that exists used for disaster recovery, but it requires an extra license. It should be included with the regular normal standard license."
"I'm not very technical, so I don't know if there are any features that are really lacking. Our customers seem pleased with it, and I haven't heard of any downsides."
"There is a need is to be able to consume Nutanix storage from outside the cluster for other, non-Nutanix workloads."
 

Pricing and Cost Advice

"The price is very reasonable when compared to other solutions."
"It's expensive, but you get what you pay for."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"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."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"The licensing is based on the number of terabytes."
"The solution is costly but reliable."
"Nutanix Cloud Infrastructure’s pricing is very good and competitive."
"The price of the license for Nutanix Acropolis AOS is less expensive than the competition. There is a favorable cost saving. Having only the need to deal with a single vendor, the management of the customer's entire stack is cost-effective."
"AHV is free! This is a great feature that should be taken advantage of."
"This product is less expensive than some of the competing HCI solutions."
"Extra features should not be so expensive. We would love to be able to use or even just try some of the extra features without having to buy them. Buying those features is just as expensive as buying vSphere licenses, so the cost savings is nullified."
"The software only licensing model is priced normally, but the licensing model that comes with hardware is priced very high. You can choose to pay the license yearly, or you can pay every three years, or every five years."
"Licensing depends on the features needed."
"The cost of Nutanix Acropolis AOS is reasonable."
