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.

Improves cost efficiency and significantly while boosting workload performance

We have realized several benefits from using Dell PowerStore; we migrated to the current Dell PowerStore models from tiered storage, and now we're using all flash. The dedupe and compression has been a big benefit for us versus the old storage that it was running, and we've seen the performance of all flash for our storage services. My company finds particular features within Dell PowerStore valuable, primarily the cost benefits for the performance that we get out of the platform. We've definitely seen the benefit on that side of it, including the cost per terabyte, and the support from Dell has been excellent as well. We haven't had any issues with it, so it's been very reliable as a platform for us. The performance metrics I use to measure success with Dell PowerStore are all IOPS and throughput. We are not using it with AI workloads on Dell PowerStore, so it's primarily just customers running IaaS, however, it is important that it's reliable and performs well, and we get that from Dell PowerStore. Dell PowerStore has supported growth and operational success for my business; a key driver at the moment is consolidation, and the dedupe and compression ratios allow us to standardize on a single platform. This has helped improve our operational metrics and overall operations, as we now have only one vendor to support and one set of storage arrays to manage. We have a very clear path into support and escalation if there is an issue, and we are not dealing with multiple vendors.

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.

Quotes from Members

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

Pros

"The latency is good."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"It has good, reliable, fast storage."

"I appreciate the performance."

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

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

"The most valuable feature of this solution is reliability."

More Pure FlashArray X NVMe pros

"The beauty is the simplicity - customers can manage multiple workloads from a single dashboard with scale-out architecture."

"The most valuable aspects of Dell PowerStore are the promising roadmap, and the interesting features to come."

"The simplicity and ease of use have been very valuable features. I have a very small team, and only half of the team is well versed in the HP product. Whereas if I bring PowerStore in, everyone can learn it because it will be new on the floor."

"The management portal is particularly user-friendly."

"I have found the most valuable part of Dell PowerStore is the price."

"Dell PowerStore has good value for money and some scalability features that are better than other products."

"The features of Dell PowerStore that I appreciate the most are that it just works; it's tried and true and amazing, and we never have to worry about it."

"Benefits of Dell PowerStore compared to Unity 400 and 650F, which we were previously using, are significant: we benefit from extensive deduplication for non-database applications, which saves us a considerable amount of costs, and the performance has improved dramatically due to advancements in technology, such as TLC disks and NVMe technologies."

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

"It is on the expensive side."

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

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

"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."

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

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

"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."

More Pure FlashArray X NVMe cons

"The support is not very good."

"The only thing is that with PowerStore, we don't have a solution for the file object."

"The initial setup was a little bit cumbersome. We had a bit of an adoption process internally. It wasn't immediately straightforward on day one."

"We experienced some concerns during a previous firmware upgrade when the controllers became unresponsive, which affected operations."

"I have experienced some downtime with Dell PowerStore, particularly due to a bug with Emulex HBAs during an upgrade process."

"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."

"Dell PowerStore could improve in the updating process and lifecycle management, as the upgrades seem to take a long time, along with some of the management features."

More Dell PowerStore cons

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

Pricing and Cost Advice

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

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

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

"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."

"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."

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

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

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

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

"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."

"It is very expensive though when you get to this point of using the 3000 with a client. They will start to think about using another vendor. There are a lot of solutions similar to PowerStore in regards to networking capacity and their prices are very cheap compared to PowerStore."

"The price is high compared to the Tunisian market."

"When we compared it with the other solutions, the pricing of PowerStore was equal. The pricing is good."

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

"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."

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

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."
