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

"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."
"From the first test that we have conducted, we are very satisfied with this solution."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"It is very easy to use."
"Pure Storage FlashArray has helped us decrease the storage footprint in a significant way; the dedupe and compression that they have is really good, and we're getting about four to ten in the deduplication and compression."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"One feature that's particularly valuable for our finance customers is Pure Storage's safe mode. It protects against ransomware attacks by taking snapshots. Our customers were very impressed with this capability. The data reduction is also impressive compared to other providers."
"Technical support is very good."
"IBM offers excellent customer service."
"We have reduced a lot of power and cooling requirements in the data center."
"We acquire companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage."
"When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."
"The IBM Spectrum Virtualize has gone from strength to strength but at the same time setting the bar for what's possible in the storage virtualization market."
"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."
"Stability has been outstanding."
"The ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."
"We were able to remove the following equipment from our infrastructure: EMC VNX5300, Cisco Switch FC, FalconStor, Cisco UCS Servers, and a lot of cabling, so in the end there is much less complexity to manage."
"Nutanix Acropolis AOS makes it easy to use and manage projects and it has a good reputation."
"The product provides a complete and wonderful package, and the best feature is the level of user-friendliness the solution offers, it's a class apart."
"We went on Nutanix Cloud Infrastructure (NCI) and were able to improve performance, but it did not really change how things worked."
"The return on investment of Nutanix Acropolis AOS is better than other solutions."
"Scalability is the most valuable feature because it is easy to scale-up and scale-out without impact in performance since it is always online."
"The beauty of this product is that it is very intelligent in controlling the data set and metadata."
"The maintenance software is straightforward because you do not need to do any configuration."
 

Cons

"It doesn’t provide enough information on performance analytics. For example, Nimble Storage has Infosight, which provides data; Pure Storage doesn’t have an equivalent."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"The solution is expensive."
"The main disadvantage of Pure Storage FlashArray is the price."
"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"Pure Storage FlashArray has not helped decrease the total cost of ownership."
"There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of."
"Scalability needs some work in some areas. The number of volumes needs to be increased drastically."
"Adding features for data deduplication is one area of improvement."
"We found a gap for smaller clients. Right now, the only offering is a huge, rack-sized storage device, and no more."
"The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve."
"Because we're so big, they have a little bit of trouble tracking all the products and making sure we get connected with the reports, but, in general, they are very good."
"The disk reliability is not that good."
"The feature that's kind of missing is getting us up to the point where we can help the application owners see where their data is at, understand it, and potentially help us breakout."
"Our client had some old Citrix Xen servers for which there is no direct migration. Nutanix has a move utility for Microsoft Hyper-V clusters or VMware clusters. You can easily migrate them using the move utility, but the Xen clusters cannot be migrated in a simple way. That is the only thing that is lacking, but nowadays, no one uses the Citrix Xen server for their clusters. Everything else is already there. Nutanix keeps on upgrading its hardware's or hypervisor's capability to be able to support new technologies."
"There are other services that Nutanix has that could be improved, but I'm not very familiar with the other services of Nutanix, such as Era and Flow. However, they seem a bit hard for us to implement and integrate with the Nutanix Acropolis AOS and other Nutanix tools. We would not dare to implement those other Nutanix solutions into Nutanix Acropolis AOS right now. The implementation of that tool could be the problem, I am a bit hesitant to implement the other tools into Nutanix Acropolis AOS."
"We'd like to have more resource management."
"It would be nice to be able to converge the network switch required to connect the Nutanix nodes together."
"In terms of what I would like to see improved, I would say the life cycle management. I don't know if it is because they changed to an LCM from the previous way of upgrading the hardware or software but sometimes it feels that it needs a wizard that says, "Check this, check this," telling you your options. The only thing that's a bit frustrating for me is the life cycle management interface. That's the only thing on the entire system that frustrates me."
"The licenses for Nutanix are very complicated."
"An area for improvement would be the cyber security features."
"In a hybrid cloud setup, we should be able to port our floors from on-premises to the public cloud and from the public cloud to on-premises."
 

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."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
"We feel that the pricing is fair and the licensing process was easy for both."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"The price of Pure Storage FlashArray is expensive."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"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."
"We would like the CPU cycle to save more on the licensing costs for us."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"This solution came as an additional cost for the TSM package we chose."
"I think it is a good value for the price."
"It has a lot of advanced functions for a reasonable price."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"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."
"Nutanix Acropolis AOS price includes no additional costs for features."
"I would rate the price seven out of ten with ten being the most expensive."
"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."
"It is slightly more expensive compared to a standard, on-prem, bare-metal configuration. There is about a 30 percent overhead there."
"My advice is to get the ultimate license, as it is worth it."
"The setup cost, pricing, and licensing are very competitive and TCO is very low compared to three-tier solutions."
"Nutanix price is high because it bundles all the components into single deals rather than allowing you to select the features that you want/will use."
"The price of the solution could improve. Nutanix has recently changed its pricing model from perpetual to subscription. They have identified there are challenges with the pricing model."
