Eugene Hemphill

Sales Manager at Multicomputos PR

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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

More Pure FlashArray X NVMe pros

"We use IntelliFlash products for larger environments, like Qatar Airways."

"It performed great originally, and when it performed great, it was awesome."

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"The initial setup is straightforward."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"Data Compression: Up to 80% space reduction in the database"

More HPE StoreOnce pros

Cons

"There is room for improvement in the pricing of the product."

"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."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

"Adding some functions to the product would be beneficial."

"The software layer has to improve."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

More Pure FlashArray X NVMe cons

"In future releases, I look forward to more AI features."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"Snapshots are not as easy to access as on a NetApp device."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"It's somewhat scalable, but maybe not so much as some of the competition."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

More DDN IntelliFlash cons

"While StoreOnce has many features, it needs to focus on integrating with third-party backup software solutions."

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

"Its customer service could be faster."

"The solution should continue to refine its integration capabilities. I also see they are starting to use cloud integration as well, which is good, but they should do more to integrate with it."

"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."

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

"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."

"The solution must provide backup options for smaller capacities."

Pricing and Cost Advice

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

"The product is expensive."

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

"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."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed."

"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."

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

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

"The solution's cost is above average."

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

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

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