Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

End-to-end NVMe capabilities helps improve availability, performance, and capacity

The solution's most valuable feature is the data reduction ratio. You can store a 5:1 ratio of your data in Dell PowerMax NVMe. For example, if you have 200 terabytes of usable capacity, you can save up to five times of data on that capacity. That means you can save one petabyte of data on just 200 terabytes of usable capacity. The solution's end-to-end NVMe capabilities have improved our operations. Everything is fast, and you don't have to map your storage to old hybrid storage technologies. Our organization has experienced positive change, and the solution has improved our uptime, availability, performance, and capacity.

Quotes from Members

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

Pros

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

"The solution uses newer technology for deduplication and compression."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"I appreciate the performance."

"The initial setup was extremely simple and straightforward."

"The most valuable feature of this solution is reliability."

More Pure FlashArray X NVMe pros

"We use ESRS for our call-home, and a lot of times, Dell EMC will respond to the issue before we even know it."

"The number one most valuable feature is reliability. I want to go home at the end of the day and come in the next day knowing it works, especially since we have storage offshore."

"The UI is very easy to use. We can add volumes and manage them easily."

"A huge benefit of the PowerMax has been the decreasing of our physical footprint. We recently did a consolidation where we went from 58 tiles down to 5. If we had used just the PowerMax, we could have gone from 58 tiles down to 2 tiles, which is huge space savings. If you have 56 newly available floor tiles on a raised floor data center, which you previously had to cool and provide power to, then now, not only are my costs going down, I now have more revenue opportunities because I have more space to put new customers."

"The upgradability and extendibility for the size of the storage unit are noteworthy."

"We like the compression, dedupe, and I/O on the PowerMax. They are better than on the XtremIO."

"The product is very fast and reliable."

"It significantly simplifies storage."

More Dell PowerMax NVMe pros

"The solution's licensing policy is more practical and not confusing."

"The solution is stable."

"The important feature is compression and duplication. It has a good compression ratio and is very stable."

"Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."

"The initial setup process is simple."

"HPE StoreOnce works well, it is stable."

"Recovery is important."

"The most valuable feature of the solution is its UI. The product's UI makes it easy for users to configure the tool."

More HPE StoreOnce pros

Cons

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

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"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."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"We need better data deduplication."

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

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

More Pure FlashArray X NVMe cons

"If you go to Pure or you go to NetApp, they deliver in one month. If you go to Dell or HP, they will take up to six months for delivery. This is not a business model for today."

"Dell PowerMax NVMe needs to increase storage and improve scalability."

"One area for improvement would be integration with public cloud services. Compared to competitors such as NetApp, which integrates with public cloud hyperscalers (GCP, Azure, AWS), Dell PowerMax lacks in this aspect."

"The NVMe integration could be improved."

"The disadvantage of PowerMax is its cost."

"Firmware updates are a bit painful because you have to involve their support, as opposed to having the ability to do it yourself."

"It's a relatively new product, but for the next release I would like to see higher bandwidth on the front-end adapters. This would allow even greater scalability for critical workloads and consolidation for non-critical workloads. The hosts may not require that level of I/O performance today. However, it allows us to scale physical non-cloud environments without large investment."

"The main challenge with the product was to have control over the simultaneous failures of controllers. For recovery, manual intervention is required."

More Dell PowerMax NVMe cons

"It is difficult to solve issues with this solution remotely. I prefer to use the knowledge base platforms. The response time could improve."

"This product would be improved with the inclusion of more features to security or WORM."

"The appliance doesn't have the global deduplication, it has StoreOnce deduplication. It does not deduplicate across the appliance, it will deduplicate in one particular store. With the global deduplication, I could store more data."

"While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring."

"The product's support is an area with certain shortcomings requiring improvements. Support needs to be faster."

"We archive our backups on tape, so I feel like if we could somehow plug our tape drive directly into the StoreOnce device and set it up to where it would archive based on, if some kind of rules based engine or what have you, that would really be an improvement for us."

"I would like to see an emphasis placed on making data deduplication and compression more powerful."

"The solution could always be less expensive."

Pricing and Cost Advice

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

"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."

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

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing for this solution is good compared to other products in the market."

"Its price is competitive, but they need to have a different price for West Africa. They can do better with the price point to allow us to scale even more. We wanted to migrate our entire storage infrastructure to PowerMax, which would require us to buy more capacity, and from the price point, it didn't attract us."

"It scales enormously, but it's expensive to do so."

"Our costs are on a yearly basis."

"The price is on the market. It's not inexpensive, but it's available on the market."

"The tool is very expensive."

"It is high-end storage and it is a bit expensive, but it is doing what it is meant for: running business-critical applications or latency-sensitive applications..."

"The pricing is comparable to other vendors."

More Dell PowerMax NVMe pricing and cost advice

"The product's pricing is medium."

"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."

"I rate the platform's pricing a seven out of ten."

"The solution is pretty expensive."

"The product is not expensive. It is available at a good price."

"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."

"HPE StoreOnce is cheaper compared to other solutions in the market."

"The solution's cost is above average."
