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.

Delivers essential support and performance for intensive operations in real-time environments

Our infrastructure is spread across the private as well as a public cloud. Our requirement was that the IOPS latency should not be more than one millisecond. If anything goes beyond one millisecond, it's a problem for us. We wanted a system that could handle the transactions and meet our latency requirements. There are performance benefits for sure. The amount of deduplication and compression offered by Dell PowerMax is quite good, especially with databases. Dell PowerMax delivers optimum performance and reliable support, integral for handling failures and ensuring operational continuity. The performance capacity optimization and support we receive from Dell are also valuable.

Mir Gulzar Ahmed

IT Manager at Synergy Computers

Offer reliable storage and servers, and their libraries are also very reliable

The only weakness is that the internal cache is low, starting from 16 GB to 64 GB. Even the larger models only have 128 GB. In comparison, NetApp storage starts with 64 GB of cache or storage memory, and their enterprise models have 128 GB or more. Hitachi doesn't offer 16 GB of cache for storage, and their options start with higher amounts like 128 GB. So, if a customer needs more cache or storage memory, the Eternus DX series is not the right solution. However, if they need a cheaper storage solution with enterprise scalability and reliability, they should consider Fujitsu. There are no additional features needed, but the software products for Eternus DX can become very expensive when used in combination. For example, the software stack for replication DR from mirroring and remote data replication is costly. Even with the complete software suite, it remains cheaper than NetApp, but the prices for individual components like deduplication, local copy, and remote copy could be reduced. It's worth noting that deduplication in Fujitsu and Hitachi is not free of cost, unlike NetApp, where it is free of cost.

Quotes from Members

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

Pros

"What I really like about this program, is that it is easy to use and easy to configurate."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"It has benefited my organization because it has reduced time to insights."

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

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The solution is very straightforward to set up."

"The high availability of the product is the most valuable feature."

"I appreciate the performance."

More Pure FlashArray X NVMe pros

"I would rate my experience with the initial setup a nine out of ten, where one is difficult and ten is easy."

"It was easy for teams to pick up the technology with very limited exposure and training, then implement and support it."

"The most important feature or function in Dell PowerMax is the capacity to deliver the required IOPS."

"The performance is very good on our servers. It's superior. And the QoS capabilities for providing work congestion protection are also important because about 99 percent of our servers are production servers."

"Dell is the best vendor worldwide, with an end-to-end solution starting from a mouse to Telza Hyperfix or HyperConverged devices."

"The SRDF replication piece is probably the best feature. It's useful for maintaining recoverability in the event of a disaster."

"The features I find most valuable about Dell PowerMax are its stability and flexibility."

"Dell support for Dell PowerMax is exceptional, rating a perfect 10 out of 10."

More Dell PowerMax pros

"Fujitsu offers a range of scalable products within the Eternus DX series, including all-flash, hybrid, and large-scale storage options."

Cons

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

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

"The tool's portfolio is minimal. It is expensive."

"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."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

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

"There are some challenges with data encryption and reduction."

More Pure FlashArray X NVMe cons

"There is some room to grow, especially with some of the installation quirks."

"I would like the scalability to improve, as it requires additional footprints."

"The REST API needs improvement. We are a very big automation company, and this would be big for us."

"The GUI interface is very complicated and could be improved by streamlining the number of steps in the process."

"The tool needs to improve its performance. Today's applications are demanding a response rate of one millisecond or below. The product should also look into AI integration."

"We would like more documentation, a guide to the features of the PowerMax."

"There might be things that engineers do at the command line that GUIs don't do."

"Dell PowerMax needs more connectivity options for projects that require separate web access."

More Dell PowerMax cons

"The only weakness is that the internal cache is low."

Pricing and Cost Advice

"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."

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

"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."

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

"The licensing is on a yearly basis."

"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."

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

"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

"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..."

"Dell is expensive compared to other products and I would rate its pricing a four out of ten."

"We hope that with the combination of both NVMe and SCM the next PowerMax will be much cheaper that the one which we acquired."

"Our costs for the product are three million."

"The pricing is comparable to other vendors."

"The PowerMax appliance pricing was reasonable. Dell EMC quoted us a substantial discount."

"One area for improvement, one that everybody always comes to, is price... it's still quite expensive to purchase these big arrays... For us, the pricing doesn't make Dell EMC uncompetitive."

"The pricing might be a bit high for small organizations, so it's more suitable for larger enterprises."

More Dell PowerMax pricing and cost advice

"The DX series is a very cost-effective solution compared to any other storage system sold by any vendor. It starts at $16,000, and no one else can provide a storage system at that price."
