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.

"The most valuable feature of this solution is its ease of use."

"The high availability of the product is the most valuable feature."

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

"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."

More Pure FlashArray X NVMe pros

"Has a great mapping feature."

"The simplicity and performance are great."

"Typically, high-performance and high-availability features, such as application snapshots and remote and local replication, are highly valued."

More HPE StoreOnce pros

Cons

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"It is on the expensive side."

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

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"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."

"We need better data deduplication."

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

More Pure FlashArray X NVMe cons

"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."

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

"The customer support is slow and has room for improvement."

"The price is on the higher side."

"Dell PowerStore should offer more cybersecurity and warehouse data security."

"We have not seen an ROI and it would be good to have an ROI calculator made available by Dell."

"After the smooth launch of the product in our company, only the areas around upgrades are a bit problematic. In our organization, we face difficulties when updating the product."

"Could use some additional automation."

More Dell PowerStore cons

"HPE StoreOnce needs to be made cheaper than products from Dell and Veeam."

"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."

"improvement? HPE StoreOnce has a limitation with respect to controllers. Other tools offer more than one controller. I feel that the high availability of the view controller should be redundant. The tool’s control and UI part should be improved and made more advanced. The feature that helps with the manual movement of tapes should also be improved."

"In terms of areas for improvement, I believe HPE StoreOnce could learn from competitors like Dell's Data Domain and ExtraHop in refining its architecture."

"Cloud integration needs to be simplified."

"The latency is a bit high."

"We're outsourced with a partner who recalls a larger amount of problems with the stability of the product."

"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."

Pricing and Cost Advice

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

"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."

"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."

"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."

"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 licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"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."

"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."

"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."

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

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

"The solution is expensive."

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

More Dell PowerStore pricing and cost advice

"I rate the platform's pricing a seven out of ten."

"The solution is pretty expensive."

"I would rate it around two or three because, compared to others, it tends to be higher priced."

"The price of the product is reasonable."

"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."

"The price puts me off. It's definitely on the high side."

"The cost of HPE StoreOnce is very expensive."

"The product is not expensive. It is available at a good price."
