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

"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The stability of Pure Storage is very very good."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"I never have to worry about its performance impacting the firm."
"It is easy to deploy and it's all-flash, so it's very fast."
"They can provide a lot of performance, so there is not a lot of difference, but efficiency is something customers value because the compression can be up to twice of the second competitor."
"Pure Storage FlashArray simplifies maintenance and management with its intuitive GUI, making storage allocation and other processes easy to understand, even for beginners."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"I assess the stability and reliability of Dell PowerScale (Isilon) as perfect, as we haven't had any hiccups with it so far."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"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."
"It is stable and very user-friendly."
"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."
"Most of the features are beneficial and one does not stand out above the rest."
"Ceph’s ability to adapt to varying types of commodity hardware affords us substantial flexibility and future-proofing."
"Stratus allows more reliability than all the other types of computers available."
"Replicated and erasure coded pools have allowed for multiple copies to be kept, easy scale-out of additional nodes, and easy replacement of failed hard drives. The solution continues working even when there are errors."
"Ceph Storage allows us to add value related to cost and offers a unique experience compared to traditional storage."
"It has helped to save money and scale the storage without limits."
"Most valuable features include replication and compression."
 

Cons

"There are a lot of things to improve."
"The initial setup of the product is complex."
"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"The solution is not cheap."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"In the past year, it hasn't been as great. They seem to just follow KBS."
"The solution is expensive. It's quite expensive for the amount of storage we have."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update."
"The price always has room for improvement."
"The solution's rate structure or rate redundancy needs to be improved."
"Dell PowerScale (Isilon) could be improved, particularly the UI, which could use some polishing as far as ease of use for the customer."
"The product lacks RDMA support for inter-OSD communication."
"What could be improved in Red Hat Ceph Storage is its user interface or GUI."
"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value."
"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."
"Rebalancing and recovery are a bit slow."
"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."
"An area for improvement would be that it's pretty difficult to manage synchronous replication over multiple regions."
"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."
 

Pricing and Cost Advice

"It's a good price point and it's a solid product for the price."
"I don't know the exact cost but it's around $1,000."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"The price of Pure Storage FlashArray is expensive."
"It is light years beyond anything else with the same price point."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"We have seen a reduction in TCO."
"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."
"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"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 paid an additional fee to have Dell's ProDeploy Plus team implement it."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"The pricing for this solution is reasonable."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"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."
"We never used the paid support."
"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 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 operational overhead is higher compared to Azure because we own the hardware."
"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."
"There is no cost for software."
