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

"The most valuable feature of this solution is its ease of use."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

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

"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."

"The database workloads are pretty fast because I frequently move data from here to there."

"Everything, especially the VMs inside, is pretty fast."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

More Pure FlashArray X NVMe pros

"Its flexibility is valuable because we have had some moments where we had to adapt, and it has been quite flexible."

"The most valuable aspects of Dell PowerStore are integration with VMware and reliability."

"I would assess the timeframes to deploy it as efficient."

"Dell PowerStore's compression and deduplication technologies are a big help for our organization."

"The features I like most about Dell PowerStore are the reliability, the time, and the performance."

"The PowerStore's compression ratio is even higher than the Unity system."

"Dell PowerStore has helped us consolidate the data into small boxes."

"This solution is highly flexible and offers efficient online compression capabilities."

More Dell PowerStore pros

"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."

"IBM FlashSystem provides the same software on each box, including virtualized solutions."

"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."

"Its ease of use, performance, and hardware compression is very useful feature."

"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."

"It's easy to use, has good stability, and many features."

"It is a very stable solution."

"Good performance with a user-friendly UI."

More IBM FlashSystem 9100 NVMe pros

Cons

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

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

"I'd like to see the product implement active replication for vehicles such as VMware."

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

"Maybe the price can be reduced since the solution is very expensive."

"I would like to see replication and DR features in the next release of this solution."

"The UI for this solution needs to be improved."

"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."

More Pure FlashArray X NVMe cons

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

"If Dell PowerStore had more controllers, making it more reliable and resilient, it would be better."

"The setup is very simple, but it's costly."

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

"The solution's pricing could be better."

"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 solution only does thin provisioning."

"If I could improve Dell PowerStore, I would suggest that integrations into backup platforms be a little more streamlined."

More Dell PowerStore cons

"The support could be better."

"The ZIO interface could be improved."

"In the future, the limitation is upgrading the same storage by adding a shelf to the desk. There is a limitation in the backend connection between the storage and extended shelf."

"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."

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

"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."

"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 needs to be improved, as it's not the best."

More IBM FlashSystem 9100 NVMe cons

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."

"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."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The licensing is on a yearly basis."

"The product is expensive."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"We are happy with the pricing that we get from Dell."

"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."

"I rate the price of Dell PowerStore a seven out of ten."

"If we use the 500 or 1000, the licensing and pricing are reasonable. PowerStore can compete with any vendor and the price isn't that expensive."

"The solution is expensive."

"Licensing is very simple. Everything is included in the basic license. There are no concerns about having to pay to add a feature. Everything is there."

"HCL Tech has a TLA with Dell, so in terms of price point, we are very competitive. Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market."

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

More Dell PowerStore pricing and cost advice

"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."

"The solution's price is competitive."

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

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

"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."

"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."
