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.

Quotes from Members

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

Pros

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"Technical support has been helpful and responsive."

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

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

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

"I appreciate the performance."

"It has good, reliable, fast storage."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

More Pure FlashArray X NVMe pros

"The feature of integrated AI and machine learning enhances the usage and operations of the storage, making it one of the key features of Dell PowerStore."

"The best features in Dell PowerStore are that it's easy to manage; for the customer user interface, customers can start learning and provision everything, and manage the system easily."

"The most valuable features are the three-to-one data reduction and the ability to scale out and up."

"Dell PowerStore has positively impacted my organization as it has allowed us to more clearly define the storage needs of each individual process or VM."

"We have implemented Dell PowerStore for small sites needing mirrored storage. To ensure high availability, the storage is set up in two different locations, possibly in the same building but far apart."

"The management portal is particularly user-friendly. We can access it easily, and the management software is not complicated."

"With Dell PowerStore, we have achieved twenty percent savings compared to the previous solution."

"I configured the storage for a customer, and they had all the scattered data placed on different servers; I consolidated all the data into a single dashboard accessible via Dell PowerStore Manager, which improves performance and IT infrastructure."

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

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"We need better data deduplication."

"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."

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

"In the future, I would like to see integration with enterprise backup systems."

"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."

"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 VNC integration or be able to use Pure Storage with VNC."

More Pure FlashArray X NVMe cons

"We'd like to see some improvements on the security side."

"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."

"After upgrades, there were a few bugs in the product, and it can be considered as an area of concern where improvements are required."

"The solution's pricing could be better."

"Even though most customers have four-hour support, it sometimes takes two days for parts to arrive when I would expect it the next day."

"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."

"The previous version of Dell PowerStore we used was easier to use compared to the current one. They have made it more cumbersome to handle, although it still works. It has become more complicated to manage."

"As a partner, I'd like to be added to each customer's CloudIQ to take a look."

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."

"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."

"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 licensing is on a yearly basis."

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

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"The pricing structure and licensing model of Dell PowerStore are very good and I like it. We chose it because it was reasonably priced and met our requirements"

"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."

"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."

"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."

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

"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."

"We purchased it with a five-year warranty."

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."
