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

"The solution uses newer technology for deduplication and compression."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

"The solution is very straightforward to set up."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"Overall stability is very good. It is a very stable solution."

More Pure FlashArray X NVMe pros

"Overall, I rate Dell PowerStore a ten out of ten."

"PowerStore is easy to use. All the drives use soft encryption. To upgrade it, you download the app, and it runs by itself. It's very easy to deploy, share, and create volumes."

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

"The improvement is massive; even a couple of milliseconds makes a significant difference to our production throughput, allowing products to leave the door more efficiently, which also cuts back on overtime and ensures we can complete our daily tasks in the required hours."

"Dell PowerStore runs effectively, and we have not had any stability or reliability problems to my knowledge."

"Dell PowerStore is highly versatile and offers numerous features that can be tailored to specific customer needs."

"I've never had to contact support, which is one of the reasons why I love it."

"That's the value Dell creates; you invest less, and you get a better ROI."

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've seen that when we create a POD in synchronous mode, it increases the latency."

"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."

"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."

"There are some challenges with data encryption and reduction."

"I'd like to see the product implement active replication for vehicles such as VMware."

"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."

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

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

More Pure FlashArray X NVMe cons

"The initial setup was a little bit cumbersome."

"We are not currently using deduplication or compression technologies with Dell PowerStore, and at this moment, we have no data about the technology from the recovery technology."

"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."

"I wish there were more options to fine-tune things. Some of the information requires deeper investigation to get data efficiency per data store."

"To improve, they could enhance their attitude and empathy by putting themselves in the shoes of the other person when providing support."

"I have not seen anything specific. The only thing I can think of that needs improvement is the price."

"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."

"There are some issues in the firmware and operational system for Dell PowerStore, such as certificate issues from legacy firmwares."

More Dell PowerStore cons

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

Pricing and Cost Advice

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

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

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"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."

"Dell PowerStore is affordable and the license is just a face license which is great."

"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."

"The price of Dell EMC PowerStore could be better, it is a bit expensive."

"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."

"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."

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

"In the pricing and licensing department, the product is always too expensive."

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."
