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.

Unified file sharing has simplified multi-tenant access and has delivered seamless data replication
Dell PowerScale (Isilon) includes its replication features; when we decommissioned our old Isilon cluster, we migrated all of the data to a new cluster, and it was pretty seamless. All you have to do is create the certificates and make those certificates available to the target cluster, then initiate a few jobs. The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once. Another suitable feature is the ability to back up your directories; you can take snapshots for all of your directories, and in fact, I believe you can take around a thousand snapshots for a single directory. The inter-replication, geo-replication is one feature. Dell provides a variety class of hardware suitable for your workloads, meaning if your data is just lab and not critical, you don't have to spend much on the hardware; conversely, if your data is mission-critical, you can buy a high-performance node from Dell. Additionally, you can span Dell PowerScale (Isilon) cluster to a large number of nodes, and code upgrades are pretty smooth because all protocols will be upgraded under a single piece of code. Since it provides a single file system that spans across the nodes, you don't have to worry about that directory structure being separately created on individual nodes, making it a fitting solution for a data lake solution because you can access the same data from multiple protocols.

Enables seamless data replication and supports comprehensive data analytics workflows
The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites. Also, important is the capability to provide RESTful APIs for custom connectors. In terms of security, I advise customers to rotate access keys to enhance protection. Additionally, scalability is effortless as you can add nodes or expand the license.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over, and we have had almost zero stability issues with that SAN, which has been really great for us."
"Our clients see a reduction in total cost of ownership by around 40%."
"We find the ease of usability and setup valuable."
"Very efficient storage"
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"Pure Storage is extremely reliable — it's never failed."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"I feel that the reliability and availability of Dell PowerScale have positively affected my company's data operations as it's running stably, and we haven't had service outages or anything of that nature, so it's been very helpful."
"Dell PowerScale helps in saving costs related to power and rack space, reducing physical hardware from over one hundred to twenty-nine chassis."
"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."
"This has really changed the way our company can acquire and process data in the field, allowing us to differentiate ourselves against all our competitors."
"Dell PowerScale overall is easy to use."
"I have absolutely seen ROI with Dell PowerScale, as the savings in staffing time and production from reducing a six-month job that could otherwise take years are substantial."
"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"IBM has the most number of additional services, this is the main advantage."
"One of Cloud Object Storage's best features is infinite capacity. This is one of the main advantages if you don't want to use your own storage. You also have the ability to write only, write once, and read many. It's like tape storage but software-based. This feature is essential for financial institutions that require that kind of protection if you write backup or data there."
"IBM Cloud Object Storage integrates well."
"One of Cloud Object Storage's best features is infinite capacity."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
 

Cons

"In the next release of the solution I would like to see Vormetric native block encryption."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"The scalability of the solution is extremely costly."
"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."
"I think replication is one area that still needs improvement."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol."
"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."
"There should be some enhancement where Dell PowerScale can have block level functionality or block storage kind of functionality."
"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."
"I would want to see more AI features with Dell PowerScale (Isilon)."
"An example of something that is problematic at the moment or that I would want to see improved is that there needs to be further delineation between access zones and settings."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."
"The performance could be better. It isn't bad, but everything is network-based, so you have a performance penalty on the network. You can never achieve the same performance as hardware. That's the disadvantage of cloud storage solutions in general. Cloud performance is one of the main issues clients have."
"Room for improvement depends on customer needs. Some customers prefer pure Object Storage using the S3 protocol, while others use a gateway in front of the storage grid to enable CIFS or NFS."
"IBM Cloud storage is not cheap, but it could be."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"If I had to choose one area, it would be making the consoles more intuitive would be helpful. Sometimes, they can be a little complicated if you're not familiar with them."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"IBM has limited cloud storage."
 

Pricing and Cost Advice

"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."
"The price is too high."
"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."
"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"Pricing is very competitive, and it's better than other competitors."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"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."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"Our company finds the pricing high, but it decreases over time."
"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."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"Pricing for this solution is reasonable."
"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."
"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."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"Pricing is not cheap."
"Like most cloud providers, IBM likely charges based on storage capacity, typically per gigabyte or terabyte. Their pricing is competitive when compared to AWS or Microsoft."
"You have the option of a monthly or yearly license. Most customers choose the monthly option. I understand what you would like to say. IBM also lets you choose among four types of Cloud Object Storage. The difference is usage, performance, etc. Of course, high-performance storage is more expensive, while low-performance storage is for cold data, and it's really cheap."
