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

"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."
"We only have storage provisioning, so the provisioning feature is good. The compression and deduplication are good."
"Once it's set up, it just runs on its own and only requires the occasional checkup."
"The stability is perfect, the reliability is 100%, and the latency is always lower than 1 millisecond."
"It has made working with storage as easy and simple as it should be."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"We have seen a good reduction in the amount of total storage space that we're using because of the deduplication."
"Support has been helpful."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"I rate this product ten out of ten."
"Its great servicing high availability. That is what it is used for."
"Spectrum Scale is one of the most important products in our environment now."
"There is nothing else that even compares to Spectrum Scale."
"The most valuable feature is the ability to share files across different platforms."
"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."
"It is a scalable solution."
"It is much easier to control data since we can run queries across all our platforms with just one solution. Not only that, we can also monitor all the platforms with Active IQ, where we can see all the alerts, messages, and space consumption through a single application. This is regardless if the data is on-prem or AWS. It is much more efficient."
"NetApp Cloud Volumes ONTAP is easy to use and gets the job done, and the granular ability to divide up the performance and the amount of storage you want is really fantastic."
"The ability to do a straight SnapMirror from our on-prem to the cloud with no other data transitions is excellent."
"The fast recovery time objective with the ability to bring the environment back to production in case something happens."
"It is a good system; it is very stable as far as what I've been using with it, and I find that support from it is really good as well."
"The FlexClones make all the management easier for us."
"CVO provides all the functionality any customer would need on cloud; it's a single solution that covers everything."
"It's very easy to set up, and within 40 minutes, you can apply storage notes in Azure."
 

Cons

"The interface lacks the same level of control as some other arrays I've used."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"The technical support is okay, but could be improved."
"There's always an opportunity for new feature functionality."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"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."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"Self-backup is the only feature lacking in this solution."
"Integration with other vendors is not available. This feature would be very helpful."
"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."
"We do have some issues where Spectrum Scale does not work as expected."
"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."
"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."
"Maybe it needs integration with HA."
"The biggest problem is that it is not able to provide block storage."
"I would like to have more management tools. They are difficult to work with, so I would like them to be a bit more user-friendly."
"Only AWS and Azure public clouds are currently available from China, and I would like to see support for Aliyun (Alibaba Cloud)."
"The navigation on some of the configuration parameters is a bit cumbersome, making the learning curve on functions somewhat steep."
"NetApp Cloud Volumes ONTAP needs to have customizable pricing options such as 10 TB increments. They seem to have only two options: 10 TB or 250 TB."
"Scale-up and scale-out could be improved. It would be interesting to have multiple HA pairs on one cluster, for example, or to increase the single instances more, from a performance perspective. It would be good to get more performance out of a single HA pair."
"The support is good in general but the initial, frontline support could be improved."
"It needs better reporting. Right now, we had to put everything one to the other just to figure out what could be the issue."
"If they could include clustering together multiple physical Cloud Volumes ONTAP devices as an option, that could be helpful."
 

Pricing and Cost Advice

"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"We have seen a reduction in TCO."
"We purchased a license to use this solution and we pay for the storage ourselves."
"It is a cheaper solution."
"There are no licensing fees aside from the support."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"The licensing is based on the number of terabytes."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"The solution is costly but reliable."
"They allow a special price if you are working closely with them. Since we have a lot of NetApp systems, we got some kind of discount. That's something they do for other customers, not just for us. The price was fair. In addition to the licensing fees, you're paying Amazon for your usage..."
"They have a very good price which keeps our customers happy."
"It is expensive. There are no costs in addition to their standard licensing fees."
"Overall, the pricing of NetApp is aggressive and the pricing becomes more aggressive as the amount of data increases. The cost for a given volume of data that you are storing becomes lower. The greater the volume of data, the cheaper the license."
"Compared to other storage vendors, NetApp, is not always able to compete with their pricing. Yet, we acknowledge the ease of use ONTAP brings with the AWS integration."
"Make sure you investigate what your requirements are going to cost you using the native cloud solutions versus what NetApp is going to cost you, to make sure you have a business case to go with NetApp."
"Cost is a big factor, because a lot of companies can't afford enterprise grade equipment all the time. They skimp where they can. I would recommend that they improve the cost."
"The cost is quite high."
