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.

Offers advanced features with notable emphasis on innovation
The best features of NetApp Cloud Volumes ONTAP include deduplication, compaction, and autonomous ransomware technology that native cloud storage solutions in AWS, Azure, or Google Cloud do not support. Moreover, NetApp Cloud Volumes ONTAP allows the use of multiple protocols including NFS, CIFS, and iSCSI, whereas native options may only support NFS and iSCSI. Customers already using on-premises NetApp storage such as FAS, AFF, or ASA can experience the same functionality on the cloud with NetApp Cloud Volumes ONTAP, which adds significant value. For data protection, customers can take advantage of the Snapshot technology available with NetApp Cloud Volumes ONTAP. This technology facilitates data recovery by allowing snapshots to be stored either on the same storage or on a disaster recovery (DR) storage. NetApp Cloud Volumes ONTAP helps us to take snapshots and store them on the same storage, with options for migration or replication of those snapshots to different storage, including on-premises DR storage or other cloud storage, providing excellent disaster recovery capabilities.

Quotes from Members

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

Pros

"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."
"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"Technical support is excellent. I've had very good responses from technical support. We had a couple of cases where we needed support. Some of the communications were purely over email and some has been an actual call to the service desk."
"The mobile app is very helpful."
"The performance is very good."
"The stability and performance are the best things about the solution."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"Its great servicing high availability. That is what it is used for."
"The high performance of the solution is its most valuable aspect; if you compare it to other storage solutions, it is much better."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."
"We can have multiple systems within the same file system."
"We tested a complete site loss with the initial loss of the complete data center and the system was always up."
"Technical support has been very helpful, and they provide us with pretty good solutions that we can implement moving forward."
"The most valuable feature is the ability to share files across different platforms."
"I would recommend NetApp any day, at any time, because there's so much hard work in it."
"Cloud Volumes ONTAP is NetApp; it's the same technology which is where the efficiency really is, and it's much more efficient than using a third-party solution."
"It gives a solution for storage one place to go across everything. So, the customer is very familiar with NetApp on-prem. It allows them to gain access to the file piece. It helps them with the training aspect of it, so they don't have to relearn something new. They already know this product. They just have to learn some widgets or what it's like in the cloud to operate and deploy it in different ways."
"By implementing Cloud Volumes ONTAP in the Azure portal, we eliminated the cost of additional hardware and everything you have to maintain on-prem in a physical environment and put it up to the cloud."
"Another feature which gets a lot of attention in our environment is the File Services Solutions in the cloud, because it's a completely, fully-managed service. We don't have to take care of any updates, upgrades, or configurations."
"I like how you can easily pair on-prem with the cloud and the cloud backup feature. I like the whole integration with on-prem and the cloud for SnapMirror relationships."
"We previously used HPE 3PAR and we switched because of the complexity we had with HPE, as it was easier with NetApp."
"My advice would be to go for it; it is a great product and a great piece of software, and NetApp is cutting edge when it comes to software in the cloud."
 

Cons

"I would appreciate improvements on daily health checks."
"The price of the solution can improve."
"Scalability is not an easy option for Pure Storage, so you have to be very careful when you are getting that product for you."
"In the next release I would like to see integration into other third-party player providers like Google."
"If I need to change or troubleshoot the dashboard, I cannot do it without calling support. If I want to move something critical, I cannot do it by myself. The dashboard blocks me from changing those critical things."
"In some cases, we get into very in-depth conversations around the movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"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."
"It's expensive, but you get what you pay for."
"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."
"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."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"Integration with other vendors is not available. This feature would be very helpful."
"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."
"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."
"Maybe it needs integration with HA."
"It would be fantastic if NetApp could offer a solution that's as user-friendly as Google Drive for seamless cloud storage integration."
"The data tiering needs improvement. E.g., moving hard data to faster disks."
"When it comes to support provided by NetApp, they have room for improvement. Every time we go through their support, we end up answering the same routine questions."
"We have had issues with everything failing back 100 percent correctly."
"We've just been dealing with general pre-requisite infrastructure configuration challenges. Once those are out of the way, it is easy."
"We have used technical support. As long as they don't call me at four o'clock in the morning to tell me that a drive failed and they are sending me another one, I like it. They have a tendency to do that."
"Some of the licensing is a little kludgy. We just created an HA environment in Azure and their licensing for SVMs per node is a little kludgy. They're working on it right now."
"The integration wizard requires a bit of streamlining. There are small things that misconfigure or repeat the deployment that will create errors, specifically in Azure."
 

Pricing and Cost Advice

"All storage is expensive so any price improvement would help."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"Pricing is moderate. It is neither cheap nor expensive."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"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 of the solution is not expensive."
"Pure has been flexible with us on the pricing models."
"The solution is costly but reliable."
"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."
"Some flexibility around the licensing model would help. The product is licensed based on capacity. Basically, the largest capacity license that you can buy is 368 terabytes. At this point, NetApp is addressing some people's concerns around this."
"The AWS consumer-based pricing model makes it easy for developers to use their credit cards to spin up virtual servers immediately."
"Our licensing is based on a yearly subscription. That is an additional cost, but because of the storage efficiencies that the NetApp gives, even with the additional cost of the NetApp license, you still end up saving money versus straight Azure native for storage. It's definitely worth it."
"In addition to the standard licensing fees, there are fees for Azure, the VMs themselves and for data transfer."
"They give us a good price for CVO licenses. It is one of the reasons that we went with the product."
"For enterprise customers, it's a very cost effective. But in the SMB segment, yeah, pricing is a little bit challenge for your time."
"The pricing of this solution is definitely higher than what the typical Azure Files and AWS solutions charge, but given the features and the stability NetApp has provided, we are okay with it. We are not complaining about the pricing."
"If we wanted to use the AWS solution, we would have to manage two or three different platforms and pay more money than what we should have to pay, as some of the features don't even exist. If we wanted to, we could use AWS cloning, but it is useless because it uses more space, is more expensive, and takes more time."
