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

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"The solution is very straightforward to set up."

"The latency is good."

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

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

"One of the best features is the support, which is excellent."

"The most valuable features of this solution are its ease of use and performance."

"The initial setup was extremely simple and straightforward."

More Pure FlashArray X NVMe pros

"The support for Dell PowerStore is exceptional; I would rate it at probably an eight or nine out of ten."

"The most valuable features of Dell PowerStore are the support for NVMe and SCM, which provides end-to-end performance and high IOPS, minimizing latency. It is a full-fledged storage solution."

"It has its own file formatting protocol, which saves a lot of space."

"Dell PowerStore has positively impacted our organization by improving the user experience, as we were having issues with the hybrid storage we had in the past, so we decided to go to an all-flash solution, and it made it possible to give a better experience because we were having heavy delays on the applications."

"In the five months we've been running Dell PowerStore, it's been 100% uptime with no issues at all, so it's been excellent."

"Moving and optimizing workloads within the cluster is quite easy based on my experience with Dell PowerStore."

"PowerStore is easy to use, powerful, reliable, and highly customizable to customer's needs."

"It's unified storage, so it can cover file, SAN, and block both. It's good storage; it gives good IOPS and less latency."

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 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."

"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."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

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

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

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"They could add more support for file storage and different types of storage."

"The tool's pricing is higher than competitors."

More Pure FlashArray X NVMe cons

"The service user is only used with the CLI and cannot log into the GUI, which is not a good feature because you cannot perform any maintenance from the GUI."

"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. Different colors are helpful when working in the data center server room."

"One thing they need to work on is creating an app sync or the Metro Cluster functionality. Currently, it requires a different hop as we have to add multiple switches to build that functionality for replication from one data center to another."

"There could be better reporting."

"It would be helpful for us to have support for the S3 protocol because our main competitor has the S3 protocol in their system."

"In one instance, a single PowerStore array provided only 3 to 4 GBPS, which was not satisfactory."

"The only improvement that might be required, though not significantly, relates to the features that allow for support, specifically the call home features."

"Could be improved by including a synchronizing feature for the file systems."

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."

"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."

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

"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."

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

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

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

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

More Pure FlashArray X NVMe pricing and cost advice

"In terms of licensing, my organization has Dell Technologies End User License Agreement (EULA), but I don't know exactly how it works, though it is a big bundle of licenses for Dell Data Domain, Dell EMC Unity XT, Dell PowerStore, Dell ECS, and all such kinds of storage arrays."

"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."

"Dell PowerStore is not a cheap solution."

"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."

"The solution’s pricing is always too high."

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

"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."

"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."

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."
