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.
Rifat Rahman - PeerSpot reviewer
Infrastructure Architect & CEO at Tirzok Private Limited
Offers reliable performance and availability for large deployments
I would like to see improvements in Red Hat Ceph Storage not because I necessarily think it needs improvement, but because I generally prefer to do things manually rather than following the containerization part. Current deployments are based on containers, but I deploy manually with my scripts and controls. If there are no Kubernetes-like requirements, I often prefer to deploy a whole manual process. I don't ask for improvements in the deployment model because Red Hat has its own philosophy about making things, but it's my personal choice that I prefer things manually. Some features are available only in the containerization part, so if those are also available in manual deployment, that will help.

Quotes from Members

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

Pros

"The most valuable feature is how it simplifies the management of the SAN."
"The all-flash disc is the most valuable feature of this solution."
"The solution has great efficiencies because it has scalability."
"It saved a lot of space, as far as physical space in our data center."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"It does efficient work of storing data while still delivering the performance that you would normally expect from a higher priced solution."
"It is a scalable solution."
"We tested a complete site loss with the initial loss of the complete data center and the system was always up."
"The profile share is a valuable feature."
"There is nothing else that even compares to Spectrum Scale."
"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."
"The most valuable feature is the ability to share files across different platforms."
"We use it for our data over multiple systems, and at the same time it is a shared file system that works pretty well for the most part."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."
"The high availability of the solution is important to us."
"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."
"Ceph was chosen to maintain exact performance and capacity characteristics for customer cloud."
"We use the solution for cloud storage."
"Companies that can afford completely flash-based pipe servers should go for Ceph because it's a very performance-intensive, brilliant storage system, and I always recommend it to customers based on its benefits, performance, and scalability."
"I would definitely recommend Red Hat Ceph Storage. It is a complete solution for cloud-native storage needs."
"Red Hat Ceph Storage is a reliable solution, it works well."
 

Cons

"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"More cloud connectivity would enhance the solution."
"The price should be lower."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"We would like to integrate it more with our backup solutions."
"I would like to see support for NVMe, end-to-end."
"We have not seen a reduction in our TCO nor have we seen ROI."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"The biggest problem is that it is not able to provide block storage."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"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."
"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."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"We do not feel as a company that the product can grow with us anymore, so we are not going to use it anymore."
"I believe there is no graphic user interface, so they should include it."
"Areas of Red Hat Ceph Storage that have room for improvement include more promotion. Many people do not know about the Stratus case, which is one of the most reliable systems available in the world, but they are not aware that a system can keep working even if there is a hardware failure."
"When it comes to the capabilities of Red Hat Ceph Storage such as object, block, and file storage, I am not fully satisfied."
"If you use for any other solution like other Kubernetes solutions, it's not very suitable."
"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."
"It needs a better UI for easier installation and management."
"Ceph does not deal very well with, or takes a long time to recover from, certain kinds of network failures and individual storage node failures."
"While the documentation for Ceph Storage is helpful, it could be improved."
"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."
