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 solution supports cross-vendor replication and diverse industries
One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

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

"All updates, upgrades, and hardware work are all performed on-line with no impact."
"Both the ease of setup and the reliability of the array makes it quite simple to manage for the customer."
"It's simple, powerful, and ready to use."
"Pure is simple to set up and manage on a day-to-day basis."
"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."
"Pure Storage is extremely reliable — it's never failed."
"Everpure FlashArray has positively impacted my organization, particularly in performance and reliability, as we've had good improvements, making our applications run faster and giving us more confidence that they will not crash."
"Like I tell everybody else that I deal with, if you want to focus your time on doing more valuable things for your company, and you deal with storage on a day-to-day basis like I do, the best thing you can do is put Pure in your environment."
"It is very good for compatibility and stability."
"The scalability is very good. It can handle anywhere from very small to large enterprise class."
"So when I say our storage services to our client were provided continuously - non-stop - for 12 months, it means that all customer servers had 100% uninterrupted, online SAN access to their data 24x7x365 (minus the power down)."
"My advice to those wanted to implement this solution would be it is very useful and will give you all the details you need; how to set up the data movers, make sure they are balanced so that the load is distributed evenly, how to set it up and get all the documents in place once you log in."
"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."
"I like that it can virtualize more than three hundred storage providers."
"It provides transparency, because of its advanced copy features."
"The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."
"One of the most valuable features of Nutanix is that it's easy to use. I love this solution—it's easy to maintain and update, and I think it's almost perfect."
"They have one of the best technical supports in my experience."
"Most beneficial feature is simplicity, ease of use."
"This operating system offers stability. Setup is straightforward."
"One of the nicest features was the migration tool, being able to take any application and migrate it over even while it was in use, and then cut it over without any downtime was very helpful."
"Data locality provides super-fast data access and ultra-low latency."
"I would encourage you to try out this product, as you will not regret it because of the stability of the technology and the other benefits you can get from Nutanix."
"Most of the enterprise vendors are in the top 10 but I'll say that this is the best that I've worked with."
 

Cons

"I would like to have support available in Spanish."
"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"We would always like to see higher performance, and lower pricing is always better."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"Automation could be simplified."
"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."
"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."
"I would like to see them provide a unified platform that offers block, file, and object-based protocol access."
"Adding features for data deduplication is one area of improvement."
"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"I have encountered stability issues in situations when the customer-provided AC power has defects."
"IBM could improve IBM Spectrum Virtualize by bundling Storage Scale and Storage Virtualize into a single appliance. This would provide a more appealing and cost-effective solution."
"One very important feature is the analysis of the logs which should be there in the system."
"Deployment could be more user-friendly - currently, it requires certain skills with the network and nodes."
"If we have one small cluster, and we need RBAC, we must install Prism Central."
"Nutanix has a complex infrastructure, we have customers that consider VMware instead. Additionally, the performance could be better."
"Nutanix Cloud Infrastructure (NCI) has really become very expensive."
"We feel that the cost for capacity is still more expensive compared to other solutions."
"We had a few problems with the foundation machine that you can use to build your systems out. We've got it working now, but it should be improved."
"There should be a little more access to Nutanix files."
"One thing I would like to eventually see from Nutanix is the ability to install the Nutanix OS on any hardware, making it hardware agnostic instead of depending on their expensive servers."
 

Pricing and Cost Advice

"The price is too high."
"It could always be lower, but it's okay."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"The pricing of Pure Storage FlashArray is reasonable."
"I would prefer that they lower their pricing."
"The pricing is reasonable."
"It is cheaper than NetApp."
"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."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"We would like the CPU cycle to save more on the licensing costs for us."
"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."
"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."
"It has a lot of advanced functions for a reasonable price."
"I think it is a good value for the price."
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."
"This solution came as an additional cost for the TSM package we chose."
"My advice is to get the ultimate license, as it is worth it."
"The price is good but I think there is still room for improvement on the price."
"Nutanix Cloud Infrastructure could be cheaper. It's costly to upgrade the solution. There are no additional costs aside from the license."
"The solution could be a little less expensive."
"When compared to the competitors, the price is reasonable."
"Able to grow with smaller, more linear increments of investment"
"We renew our license on a yearly basis and have no costs in addition to the standard fee."
"I know Nutanix and VxRail have similar prices and licenses. Nutanix is a go-ahead if AHV is used as hypervisor because it is already embedded in the price."
