All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services
The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

File sharing has supported collaboration and disaster recovery but security support still needs work
Dell PowerScale can improve specifically for AI workloads, particularly on the MCPs. I would add that we have not seen an official MCP from Dell PowerScale and are relying on open source. It would be valuable to have an MCP server that we can set up directly with them. Regarding Dell PowerScale's AI capabilities, I think its governance and security could be better. We have Superna that we buy along with Dell PowerScale, but we are seeing very big problems with integrating it. Superna is primarily for the security use case, as we want to prevent cybersecurity attacks and ransomware attacks. If Dell is providing this as a supplementary feature, it should provide better support. Regarding Dell PowerScale's AI capabilities, I do not see much accuracy and reliability of output. This is actually a security problem because Dell does not provide official MCP servers while most other vendors are providing it. This forces us to rely on open source, which is not secure. Dell PowerScale plays a role in my organization's AI initiatives as we want to use the Metadata IQ functionality from Dell PowerScale; however, there is not enough support and extensive documentation for us to be able to do this.

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

"Everpure FlashArray has reduced downtime in some situations, reduces downtime considerably, and can help perform upgrades or replacements of certain hardware or its firmware without shutting the machine down."
"It helps to simplify storage because it has an easy front-end to access everything."
"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"When you put all of the features in a box, leverage them and migrate your application to one of these arrays, it will give you a lot of benefits."
"The best features of Pure Storage are their support and analytics."
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"Overall, Dell PowerScale (Isilon) has made the management of the data and networks easier."
"The solution has simplified management by consolidating our workloads, and rather than managing all the different workloads on different storage arrays and Windows Servers, we just have one place per data centre where we manage all their unstructured data, saving us time."
"Dell PowerScale seamlessly integrates with our entire infrastructure."
"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."
"I have seen a return on investment with Dell PowerScale, as it has definitely saved many of our resources."
"Using this product has enabled us to maximize the business value of our data because now, we can store all of our data in one place."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"Dell PowerScale (Isilon) actually combined a shared file system that scales seamlessly and works effectively, making the blocking and tackling exactly what was advertised."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"IBM Cloud Object Storage integrates well."
"One of Cloud Object Storage's best features is infinite capacity."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"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 has the most number of additional services, this is the main advantage."
 

Cons

"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"I would prefer that they lower their pricing."
"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."
"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."
"The file functionality could be better."
"There should be some enhancement where Dell PowerScale can have block level functionality or block storage kind of functionality."
"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."
"Isilon has limitations on the number of files that can be generated."
"I have not seen a great return on investment from Dell PowerScale. It would benefit significantly more if users adopted it, but unfortunately, I do not see that happening at the moment."
"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."
"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."
"Dell PowerScale (Isilon) is a bit expensive compared to other products."
"IBM Cloud storage is not cheap, but it could be."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"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."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"IBM has limited cloud storage."
"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."
"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 improvement could be incorporating a feature similar to Dropbox's version history. This would allow users to track modifications made to files over time, which is particularly important for maintaining a record of changes. While the free version might not include this feature, it could be included in the paid version to provide added value to clients. Additionally, having a version history feature that allows users to access modifications made to files over the past three months could be beneficial."
 

Pricing and Cost Advice

"The pricing of Pure Storage FlashArray is reasonable."
"It is a cheaper solution."
"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."
"Pure Storage FlashArray is expensive."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"Pure Storage FlashArray's pricing is very competitive."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"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 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."
"Pricing for this solution is reasonable."
"The price of Dell PowerScale (Isilon) is reasonable."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"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."
