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.

It's constantly enhanced and has impressive reliability and data compression

The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal. I hope Dell addresses that. Everything is pricey these days anyway. It is not like the old days of Compellent. We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that.

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

"I appreciate the performance."

"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."

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

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

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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

More Pure FlashArray X NVMe pros

"Dell PowerStore is very simple to implement, and its user interface is very simple."

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

"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."

"The simplicity and performance are great."

"The product is reliable and stable."

"You can add compute and capacity independently. We have sized the solution based on our current needs, but in the future we can choose to increase capacity if we grow our activity in the market. And if we have more business in our monetary system, we can increase compute. The ability to choose what we increase is a good feature."

"The most valuable feature of Dell PowerStore is its immutable storage, which is what we are looking for. It offers high protection in terms of ransomware protection."

"We used Cloud IQ. The central management and outside support functionality were great since we had systems all over the world."

More Dell PowerStore pros

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

Cons

"The software layer has to improve."

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

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

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

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

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

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"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."

More Pure FlashArray X NVMe cons

"Data reduction needs improvement."

"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 solution only does thin provisioning."

"Dell PowerStore is a very expensive storage solution. That said, the speed for recovering information is amazing. I would make the product cheaper. The discounts from Dell to South America are not sufficient because we need better pricing. The discounts for small PowerStores are not enough to close deals since I'm a distributor. As both a user and seller, it's challenging to sell Dell PowerStore to the channel or final customers because we don't have enough discount from Dell."

"Some of the data metrics we get out of Pure from a support perspective online are a little bit more robust than the Dell PowerStore metrics, but it's not a negative against Dell."

"One improvement I would suggest relates to the service that pings Dell when there's an issue. I would say it needs to be more transparent."

"It needs more mature code."

"I would suggest that Dell PowerStore could come with various other features, such as a hybrid model apart from only all-flash, which would really help the customers."

More Dell PowerStore cons

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

Pricing and Cost Advice

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

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

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

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

"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 product is expensive."

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

More Pure FlashArray X NVMe pricing and cost advice

"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."

"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."

"There's still a cap on the upgrade path, where you can consume all the engines within the frame before you have to go to another frame... Normally, we exceed the IOPS on the frames before we can ever exhaust the storage, so anything they can do to help us avoid stranded storage capacity, capacity that we couldn't get to, would be beneficial."

"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 price is high compared to the Tunisian market."

"The software features are included in the pricing without any additional purchase requirements."

"Dealing with the licensing part of the product is very simple, especially considering the fact that we don't have many licenses associated with the tool."

"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."

More Dell PowerStore 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."
