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 reliability."

"One of the best features is the support, which is excellent."

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

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

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"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."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"The solution is very straightforward to set up."

More Pure FlashArray X NVMe pros

"The way you're able to manage all your PowerStores as one solution is very good for us. PowerStore enables you to federate or cluster multiple appliances with automated load balancing. In terms of management, it's helpful that we can do it from a single interface where we're able to manage multiple PowerStores. When you have multiple PowerStores it works intelligently by running the workloads based on the needs of the infrastructure."

"Dell PowerStore offers features that are easy to deploy and work very well."

"The product's initial deployment phase has been straightforward."

"Dell PowerStore has been used for around three or four years, and the experience with Dell PowerStore has been positive."

"Dell PowerStore is a mid-range product that can suit small companies and provides good IOPS and performance."

"Dell PowerStore has positively impacted our organization by improving the user experience, as we were having issues with the hybrid storage we had in the past, so we decided to go to an all-flash solution, and it made it possible to give a better experience because we were having heavy delays on the applications."

"The most valuable feature is the three-to-one data reduction."

"I've never had to contact support, which is one of the reasons why I love it."

More Dell PowerStore pros

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

"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."

"The most valuable feature is the speed."

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

"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."

"It is a very stable solution."

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

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

More IBM FlashSystem 9100 NVMe pros

Cons

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

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

"In terms of what needs improvement, the dashboard and management could be simplified."

"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."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"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."

More Pure FlashArray X NVMe cons

"There are some management issues in Dell PowerStore. I have managed several pieces of Dell PowerStore's hardware area, and I could feel that it was almost like a step back in certain areas when it came to the management interface."

"We question that quite often because they have been increased by thirty to thirty-five percent every quarter for unexplained reasons, and that definitely does not go down well with customers."

"Dell PowerStore does not have features that specifically cater to the needs of our company or industry that are outstanding among others, but reliability is crucial, and ease of management is also important."

"I have experienced some issues, downtime, and outages with Dell PowerStore, as we have had quite a few issues related to storage and resilience."

"I would rate Dell PowerStore seven or eight out of ten. There are always areas for improvement, which I mentioned earlier."

"The biggest area in PowerStore that needs improvement is the overall visibility within the ESX environment."

"More demonstration and training options are needed."

"Customer service is good, though if you are running into some issues where you have to chase after them or they do not understand what is going on, overall it is pretty good."

More Dell PowerStore cons

"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."

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

"The pricing should be more competitive."

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

"I'd like to be able to connect to tape drives behind the storage device to back up the tape if need be. We have all of our storage running in all-flash, and we make a copy on tape. Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex. We want IBM to add a feature where we could install a tape into the storage so that we can connect it through a single pane of glass. We'd like to have a feature in the IBM flash storage system so that we can connect backup tape drives through the IBM storage system and we can manage the backup tape from the storage system."

"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."

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

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

Pricing and Cost Advice

"Given its price, Pure is not the first option."

"We pay approximately $50,000 USD per year in licensing fees."

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

"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."

"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."

"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."

"The licensing is on a yearly basis."

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

More Pure FlashArray X NVMe pricing and cost advice

"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."

"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."

"As compared to others, PowerStore is cheaper."

"The rate is always too high. Nobody likes paying for it. I have not seen a client yet who says that the price should be higher. Initially, people look at it, but when they see what the benefits are, it is a no-brainer. We can give them good pricing at the outset."

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

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

"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."

"Dell PowerStore is affordable and the license is just a face license which is great."

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."

"The tool's pricing is competitive."

"The solution is priced well."

"The product has an average cost."

"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."

"The solution's price is competitive."

"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."

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