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.

Integrated AI and clustering enhance storage operations effectively

I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.

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.

"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

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

"The UI for this solution needs to be improved."

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

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

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

"It is on the expensive side."

More Pure FlashArray X NVMe cons

"I would improve Dell PowerStore by enhancing the replication feature because currently, users are limited to one applier, from one cluster, a Dell PowerStore cluster, to another Dell PowerStore cluster, but are not able to configure a three-site scenario."

"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."

"Dell PowerStore doesn't really have a lot of advantages over other products. It has no special features technically. Other products have better management and analytics features."

"With PowerStore, we have to choose between block storage and NAS functionality."

"If I could improve anything about Dell PowerStore, there are a couple of in-the-weeds features that I would want to see, such as the size of snapshots to know when we can expire some of them."

"The setup process could be improved. We had some issues regarding configuration and the time it took to do things. It wasn't specifically the people we worked with, but more the process and how it's done. They can work on that."

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

"It's also only supported with a limited amount of switches."

More Dell PowerStore 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."

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

"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 licensing is on a yearly basis."

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"HCL Tech has a TLA with Dell, so in terms of price point, we are very competitive. Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market."

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

"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."

"There are no separate licenses required as all the basic licenses are included in the bundle."

"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"

"Dell PowerStore is not a cheap solution."

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

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

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."
