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

"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."
"The performance levels and the storage have improved my organization because we're a 95% virtualized environment and we're able to allocate resources as needed and manage our whole infrastructure that way."
"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"If you factor in the ease in terms of operations, as well as the cost of the array compared to other solid state arrays, it becomes a clear positive for Pure Storage."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"We can have multiple systems within the same file system."
"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."
"I rate this product ten out of ten."
"Technical support has been very helpful, and they provide us with pretty good solutions that we can implement moving forward."
"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."
"It is incredibly scalable and stable."
"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."
"Allows us to share files across multiple environments."
"Ceph was chosen to maintain exact performance and capacity characteristics for customer cloud."
"It's possible that we should have used the solution a long time ago as it appears to cost the business less money to run some of our data systems using it."
"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."
"It opens doors for completely open-source cloud."
"We have some legacy servers that can be associated with this structure. With Ceph, we can rearrange these machines and reuse our investment."
"The setup is very easy, deserving a ten out of ten."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"We have not encountered any stability issues for the product."
 

Cons

"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"Regarding documentation, it would be helpful if we could have access to the root passwords for administrative tasks."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"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."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"There is room for improvement in the web interface. There could be more information available, such as charts and graphs to monitor performance."
"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."
"Integration with other vendors is not available. This feature would be very helpful."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."
"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."
"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."
"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value. Go below 3 and problems will arise."
"Geo-replication needs improvement. It is a new feature, and not well supported yet."
"What could be improved in Red Hat Ceph Storage is its user interface or GUI."
"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."
"I've heard the integration with OpenShift is great, however, the licensing cost is excessively high."
"Ceph Storage lacks RDMA support for inter-OSD communication. That is a huge loss in terms of performance."
"We have encountered slight integration issues."
"The management features are pretty good, but they still have room for improvement."
 

Pricing and Cost Advice

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"The price, in general, is around $100,000, however, I know it costs more."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"It's a good price point and it's a solid product for the price."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"The solution could be cheaper."
"You get what you pay for. It is expensive, but it really works."
"Its price is almost double than any other flash storage 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."
"We never used the paid support."
"The price of this product isn't high."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"The price of Red Hat Ceph Storage is reasonable."
"I rate the product’s pricing an eight out of ten."
"The operational overhead is higher compared to Azure because we own the hardware."
"There is no cost for software."
"If you can afford a product like Red Hat Ceph Storage then go for it. If you cannot, then you need to test Ceph and get your hands dirty."
