Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Resilience has supported proactive management and secured audit readiness across multiple sites

The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

Quotes from Members

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

Pros

"FlashArray has some fresh efficiency features, I've never seen a storage solution with a compression rating this high before, it's at least 4-to-1 on Oracle databases, it's the best flash storage for Oracle."

"Its speed is superior to our existing Unity x00 model and it has performed substantially better than our x00 model and a little bit better than our x50 model."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."

"Overall stability is very good. It is a very stable solution."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

More Everpure FlashArray X NVMe pros

"The most valuable feature is the functionality of the integration between the storage and the domain."

"PowerStore is easy to use, powerful, reliable, and highly customizable to customer's needs."

"The most valuable features of PowerStore are its density and data reduction."

"In terms of reliability, scalability, compression, deduplication, and TCO, Dell is a preferred partner."

"The best features in Dell PowerStore are that it's easy to manage; for the customer user interface, customers can start learning and provision everything, and manage the system easily."

"The most valuable feature of Dell PowerStore is the speed."

"The feature of integrated AI and machine learning enhances the usage and operations of the storage, making it one of the key features of Dell PowerStore."

"We started working with the first generation Dell PowerStore in 2020, and our customers are already migrating to the second generation."

More Dell PowerStore pros

"It is a high-performance product that serves our requests well."

"The most valuable feature is the speed."

"It is a very stable solution."

"The FlashCore modules support more value to the architecture due to their unique characteristics."

"The product is a game-changer; IBM changed the game architecturally by moving computational resources into the flash media."

"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."

"The technical support is good."

"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."

More IBM FlashSystem 9100 NVMe pros

Cons

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"They could add more support for file storage and different types of storage."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"There is room for improvement in the pricing of the product."

"Adding some functions to the product would be beneficial."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

More Everpure FlashArray X NVMe cons

"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."

"The support is not very good."

"Dell PowerStore could improve in the updating process and lifecycle management, as the upgrades seem to take a long time."

"The management UI is pretty decent and gets the job done, but the upgrade process is challenging."

"Improvements could be made in the replication solutions of Dell PowerStore. Even though replication between Dell PowerStores is possible, high latency connectivity is problematic."

"The pricing point must have better positioning."

"The service user is only used with the CLI and cannot log into the GUI, which is not a good feature because you cannot perform any maintenance from the GUI."

"I would say it needs easier or increased compatibility with other storage solutions for easier application, such as Dell's own PowerVault. They don't communicate or talk to each other, and they don't replicate to each other, which makes it harder to mix and match."

More Dell PowerStore cons

"We're not satisfied with the deduplication and compression for our volumes."

"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."

"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."

"The solution's compression feature could be better."

"The tool's architecture is complex. It also needs to add data utilization reports."

"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"The storage system itself should have built-in capabilities for different ransomware attacks."

Pricing and Cost Advice

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"The support cost per array is about $20,000 a year for 24/7 support."

"The licensing is on a yearly basis."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"With VMware, we pay $300,000 annually."

"Our licensing fees are $500,000+ USD."

More Everpure FlashArray X NVMe pricing and cost advice

"The price is high compared to the Tunisian market."

"There are no separate licenses required as all the basic licenses are included in the bundle."

"As compared to others, PowerStore is cheaper."

"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."

"The licensing for this solution is good and is in the mid-range tier."

"The pricing rates at seven out of ten as it is considered overpriced. Entry-level models are reasonably priced, starting around $30,000 for a base model with 6 drives. However, upgrades become costly - adding 6 additional drives can cost another $30,000."

"When we compared it with the other solutions, the pricing of PowerStore was equal. The pricing is good."

"It is easy to work with Dell from the licensing perspective."

More Dell PowerStore pricing and cost advice

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."

"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."

"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."

"Compared to its competitors, IBM's offering is the most cost-effective."

"The product has an average cost."

"The price of the FlashSystem 9100 NVMe is reasonable."
