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.

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.

"The solution's migration feature is very valuable, but the most valuable thing is that more features appear with every iteration of the software."

"Dell PowerStore has rarely had any downtime."

"Dell PowerStore provides measurable benefits in performance because it uses all-flash disks while our old storage relied on mechanical hard disks."

"The main feature of Dell PowerStore is its support for NVMe as well as hybrid solutions."

"PowerStore is robust compared to the previous models like Unity, and it provides excellent compression and deduplication."

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

"The graphical interface does everything and we don't need to use the CLI; we can do everything, and it's user-friendly and simple."

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 UI for this solution needs to be improved."

"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."

"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 are some challenges with data encryption and reduction."

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

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

"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."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

More Pure FlashArray X NVMe cons

"Horizontal scaling has room for improvement."

"Dell PowerStore should offer more cybersecurity and warehouse data security."

"Dell PowerStore has minimal areas needing improvement, as it is one of the best products in Dell's portfolio. However, migration services could be included, especially for Oracle migration."

"The design needs to be something similar to Pure Storage. It would be beneficial if there are different color or lighting options for different product casings."

"It was very new when we first deployed it a year ago. Even the upgrade processes and knowing what to expect, as well as documentation, could be more robust."

"The deployment of Dell PowerStore would not be described as easy, and it would not be described as challenging."

"After the smooth launch of the product in our company, only the areas around upgrades are a bit problematic. In our organization, we face difficulties when updating the product."

"However, I can see that the software needs to mature more; whenever we upgrade to a new version, even if it is the Dell recommended version, we still encounter major bugs that can impact business operations."

More Dell PowerStore cons

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

Pricing and Cost Advice

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

"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."

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

"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."

"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."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The price of Dell PowerStore could improve. The price should be managed more compared to Huawei Dorado or IBM All-Flash series."

"It is expensive compared to one of its competitors."

"As compared to others, PowerStore is cheaper."

"The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."

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

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

"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."

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."
