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.
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 stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"It has improved my organization in the way that we have high reliability and faster access to our data."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance."
"The GUI is very easy to use and intuitive."
"FlashArray's data reduction and NAS features are incredible. Its performance is the best I've worked with."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"The performance of the storage is just unbelievable."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."
"Dell PowerScale overall is easy to use."
"Dell PowerScale (Isilon) actually combined a shared file system that scales seamlessly and works effectively, making the blocking and tackling exactly what was advertised."
"Dell PowerScale (Isilon) is scalable, it is easy to expand capacity, and the solution is suitable for companies with a lot of data."
"The tool's most valuable features are high density and scalability."
"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."
"The technical support has been excellent. I would give them a ten out of ten for support."
"The capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it."
"It opens doors for completely open-source cloud."
"What I found most valuable from Red Hat Ceph Storage is integration because if you are talking about a solution that consists purely of Red Hat products, this is where integration benefits come in."
"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."
"The product spawned a new vision of storage deployment, as well as a strong interest in reusing equipment and increasing ROI."
"The scalability feature is used by all users and is critical for our operations."
"Ceph has simplified my storage integration. I no longer need two or three storage systems, as Ceph can support all my storage needs. I no longer need OpenStack Swift for REST object storage access, I no longer need NFS or GlusterFS for filesystem sharing, and most importantly, I no longer need LVM or DRBD for my virtual machines in OpenStack."
"Without any extra costs, I was able to provide a redundant environment."
"We use the solution for cloud storage."
 

Cons

"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"I would like to see support for NVMe, end-to-end."
"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database, the whole array went down, so our customers were down for around eight hours."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says it is completely full."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"Additional metadata reporting would be great. We have to use a separate tool to report on that. We would like to view the age of data and how long it has been since someone has accessed a file."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol."
"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."
"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."
"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."
"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value."
"It needs a better UI for easier installation and management."
"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."
"Routing around slow hardware."
"While the documentation for Ceph Storage is helpful, it could be improved."
"It needs a better UI for easier installation and management."
"Geo-replication needs improvement. It is a new feature, and not well supported yet."
"The management features are pretty good, but they still have room for improvement."
 

Pricing and Cost Advice

"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"We have seen a reduction in total cost of ownership (TCO)."
"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."
"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 price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."
"FlashArray is expensive, but the quality justifies the price."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"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 pricing is excellent."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"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."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"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."
"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."
"There is no cost for software."
"The price of this product isn't high."
"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."
"The price of Red Hat Ceph Storage is reasonable."
"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.​"
"I rate the product’s pricing an eight out of ten."
"We never used the paid support."
