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.

Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

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 solution is stable with low vulnerabilities."
"The benefits were realized right away. Between the flash array and the compression, you can really see how good it is. Our databases run a lot better now."
"We saw a vast improvement when we switched over to using the Pure Storage model over the XtremIO."
"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"Performance is the most valuable feature."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"Pure Storage is extremely reliable — it's never failed."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"Its scalability has been huge for us."
"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."
"My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime."
"The solution is extremely easy to manage. This is its most valuable feature."
"Dell PowerScale (Isilon) is brilliant for scalability and really, really good in that regard."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"Dell PowerScale (Isilon) helps improve the way the organization functions through massive scalability, high performance, a single file system, high availability and reliability, flexible protocols, support for NFS, SMB, HDFS, strong security, cloud integration, efficiency, data protection, snapshot, queue, and sync queue, optimized for unstructured data."
"Data redundancy is a key feature, since it can survive failures (disks/servers). We didn’t lose our data or have a service interruption during server/disk failures."
"I would definitely recommend Red Hat Ceph Storage. It is a complete solution for cloud-native storage needs."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"High reliability with commodity hardware."
"Without any extra costs, I was able to provide a redundant environment."
"We have not encountered any stability issues for the product."
"I like the distributed and self-healing nature of the product."
"The community support is very good."
 

Cons

"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"The solution needs an integrated NAS platform, file platform."
"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."
"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."
"They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"Dell's customer service needs improvement."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"We're struggling with the UID mapping and how to configure mapping-related things."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"Data storage performance needs to be improved."
"Ceph is not a mature product at this time. Guides are misleading and incomplete."
"Ceph is not a mature product at this time. Guides are misleading and incomplete. You will meet all kind of bugs and errors trying to install the system for the first time. It requires very experienced personnel to support and keep the system in working condition, and install all necessary packets."
"Rebalancing and recovery are a bit slow."
"I would like to see better performance and stability when Ceph is in recovery."
"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."
"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."
"If troubleshooting is needed, the response should be faster."
"Routing around slow hardware."
 

Pricing and Cost Advice

"There are no fees for licensing. The hardware is paid for only once."
"The price of the solution is not expensive."
"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 cost has room for improvement."
"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."
"We feel that the pricing is fair and the licensing process was easy for both."
"We have seen a reduction in total cost of ownership."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."
"The solution's licensing cost varies based on capacity and performance requirements."
"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."
"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"There is no cost for software."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"The operational overhead is higher compared to Azure because we own the hardware."
"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."
"I rate the product’s pricing an eight out of ten."
"We never used the paid support."
"The price of Red Hat Ceph Storage is reasonable."
