Helps to save money and resources with the data compression feature

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. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Reduces the footprint, is easy to use, and can handle heavy workloads

The systems I currently have in place are old, and their support is running out. They're at the end of their life cycle. One of the key improvements that PowerStore is going to bring is that it will enable me to shrink the physical footprint. I'll be going from 5 physical HP arrays, which are about 12 racks in size, down to 4 PowerStores, which can fit on one rack. As a result, I'll be able to shrink the footprint, save power, cooling, etc. I will also be able to improve the existing performance and longevity of the platform. When we put the PowerStore in for the Oracle database, it was previously on NetApp. The staff wanted to do snapshots but also clone, and then be able to clone from a clone to add it to another system. PowerStore enabled them to do just that. They not only got their performance back to where it needed to be from previously being on the NetApp array but also got some of the feature functions that they require for the application.

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 duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"It has benefited my organization because it has reduced time to insights."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"The latency is good."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

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

More Pure FlashArray X NVMe pros

"The solution is stable."

"It's a great product. Integrating PowerStore with the IT workflow is easy."

"The simplicity and performance are great."

"The PowerStore's compression ratio is even higher than the Unity system."

"It is very easy to use. Access is very friendly. It shows you a lot of important information at the first glance. It has been very easy to use."

"It is a stable solution."

"The most valuable features of Dell PowerStore are the resilience, scalability, flexibility of expansion, and ease of managing the entire solution including the servers and storage."

"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."

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

"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."

"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."

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

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

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

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

"The software layer has to improve."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

More Pure FlashArray X NVMe cons

"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."

"I do not like having to use VPLEX for synchronous replication, as opposed to having the store software built-in."

"During the installation phase, the licensing part was not straightforward. It was very difficult for the technicians, who are not trained Dell EMC technicians, to do the licensing because the information on their website is not straightforward... Eventually, I had to pass this task to our business partner and they did it for us."

"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."

"Where the system needs to improve is by adding more enterprise features like replication on other sites. We would also like it to be much more aligned with the VMware version. For example, today we have two different versions of VMware ESXi running to keep the PowerStore online. It would be better if the software cycling was faster."

"Dell PowerStore currently only allows us to copy data from our main production system to the disaster recovery site."

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

"Dell PowerStore is too expensive, and it could be less complicated. It isn't as user-friendly as other options, especially regarding the user interface."

More Dell PowerStore cons

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

Pricing and Cost Advice

"The product is expensive."

"With VMware, we pay $300,000 annually."

"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 licensing is on a yearly basis."

"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."

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing is good. There's no need to pay for a license; it's all-inclusive."

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

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

"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."

"Dell PowerStore is not a cheap solution."

"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."

"The solution is expensive."

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

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."
