Featured Reviews

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.

Efficient data replication and fast IOPS have improved operational performance

Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

Quotes from Members

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

Pros

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

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

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

"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."

"The most valuable features of this solution are its ease of use and performance."

"Technical support has been helpful and responsive."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"The latency is good."

More Pure FlashArray X NVMe pros

"It is easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened."

"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."

"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."

"Replication of the communication object (COB) scenarios"

"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."

"The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like."

"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."

"It is simple to use and easy to manage. We don't touch it after we set it up."

More Dell Unity XT pros

"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."

"Deduplication is the most valuable feature."

"From a centralized system, I can manage the interface, the backup policies, and the status of the database."

"The stability of the solution is excellent."

"HPE StoreOnce works well, it is stable."

"The interface is very user-friendly."

"If you have a large enough storage capacity then you can take an ample amount of data."

"The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure."

More HPE StoreOnce pros

Cons

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"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."

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

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

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

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

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

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

More Pure FlashArray X NVMe cons

"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."

"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT."

"I would like them to continue to build on the solution and expand on the functionality, like replication."

"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."

"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."

"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."

"Licensing costs could be reduced."

"We need to improve the controller to work as active-active. We also need to improve the snapshot on the Unity site."

More Dell Unity XT cons

"I would like to see better integration with Veeam software."

"One item I wanted to see is SSD drives as a cache, and that was, for a time, still lacking in StoreOnce, however, they have done it now. It's not available yet, however, it will be shortly."

"The GUI and its user-friendliness have some room for improvement."

"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."

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

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

"We stopped investigating because we were not really happy with the application."

"This product would be improved with the inclusion of more features to security or WORM."

More HPE StoreOnce cons

Pricing and Cost Advice

"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."

"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."

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

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

"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."

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

"The product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."

"It is a good return on investment."

"It scales, but then you have to buy additional stuff."

"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."

"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."

"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."

"We have to apply for a license for each system."

"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."

More Dell Unity XT pricing and cost advice

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

"The product's pricing is medium."

"The licensing costs is capacity-based and come bundled with support."

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

"The price of the product is reasonable."

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

"HPE StoreOnce is cheaper compared to other solutions in the market."

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
