Sowjanya MV

Technical Lead at Wipro Limited

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

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

"One valuable feature of the Pure Storage FlashArray is its Flash-based architecture, which provides a significant advantage."

"The most valuable feature is its upgradeability."

"We are finding the TCO of flash to be lower than SSD implementations."

"For VMware, it has been a humongous savings."

"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."

"We find the ease of usability and setup valuable."

"The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."

"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."

More Everpure FlashArray pros

"The features that I have mentioned improve my company through the reliability of the storage; it is always available, and it works, which is the important thing."

"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."

"What I like the most about Dell PowerScale (Isilon) is that the storage capacity is very high."

"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product."

"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."

"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."

"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."

"My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."

More Dell PowerScale (Isilon) pros

"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."

"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. In particular, Red Hat Ceph Storage becomes a single solution for managing the entire environment in terms of the container or the infrastructure, or the worker nodes because it all comes from a single plug."

"We have not encountered any stability issues for the product."

"Most valuable features include replication and compression."

"It has helped to save money and scale the storage without limits."

"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."

"We are using Ceph internal inexpensive disk and data redundancy without spending extra money on external storage."

"I really like that Red Hat Ceph Storage can be used as a total solution without any storage area network components."

More Red Hat Ceph Storage pros

Cons

"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. 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."

"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."

"I feel like there is too much automation; the user doesn't have any manual input."

"The speed can always be improved."

"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."

"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."

"Had some issues with Purity not being entirely compatible with VMware ESXi."

"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."

More Everpure FlashArray cons

"Dell PowerScale needs to reduce its price."

"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."

"The solution lacks a cloud version."

"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."

"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear."

"The product’s expansion capacity, pricing clarity, and ease of use need improvement."

"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

More Dell PowerScale (Isilon) cons

"While the documentation for Ceph Storage is helpful, it could be improved."

"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."

"Geo-replication needs improvement. It is a new feature, and not well supported yet."

"It took me a long time to get the storage drivers for the communication with Kubernetes up and running. The documentation could improve it is lacking information. I'm not sure if this is a Ceph problem or if Ceph should address this, but it was something I ran into. Additionally, there is a performance issue I am having that I am looking into, but overall I am satisfied with the performance."

"I have not identified any drawbacks, however, the response to public platform inquiries could be faster."

"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."

Pricing and Cost Advice

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."

"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 pricing is very attractive and it delivers performance for the money."

"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

"It's a good price point and it's a solid product for the price."

"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."

More Everpure FlashArray pricing and cost advice

"It is a really expensive solution."

"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."

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

"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."

"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."

"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 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."

"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."

More Dell PowerScale (Isilon) pricing and cost advice

"The price of this product isn't high."

"I rate the product’s pricing an eight out of ten."

"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."

"There is no cost for software."

"We never used the paid support."
