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.

Provides a cloud-like operation model on-prem for managing data infrastructure

I've always said I love that it's easy to use. At one point in time, we had a 3PAR. And with 3PAR, I always thought it was a little more difficult. There was so much more to maintaining it, setting it up, and everything. With the [HPE] Alletra [Storage], it's just easy. It's easy to provision space to use and to set up. InfoSight is invaluable to me. With it, I can just quickly go out there and see what is going on. Alletra provides a cloud-like operation model on-prem for managing data infrastructure. [HPE] Alletra [Storage] is very good for predicting problems and preventing them before they occur. InfoSight has really helped with that. I honestly don't have to look at it much. However, there's the alerting and everything that will tell us what's going on. That said, I check InfoSight every once in a while. [HPE Alletra Storage] reduced the time spent on storage provision. It's so much easier than the 3PAR. It's just so much easier. I don't spend time in there at all. The product improved our storage performance experience in terms of IOPS. Our end users that use the SAP environment were a little concerned at first. We said we were going to switch over from the 3PAR to the Alletra since they've always been more familiar with the 3PAR. However, when we moved them over, they noticed a performance increase.

Quotes from Members

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

Pros

"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 database workloads are pretty fast because I frequently move data from here to there."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The solution uses newer technology for deduplication and compression."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

More Pure FlashArray X NVMe pros

"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."

"I like that the performance is very good."

"Initial setup is a simple process."

"I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."

"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."

"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."

"Compared to our old platform, everything is more tightly integrated. I don't have to go to different sections to do something. A lot of it is wizard-driven, so it's an easy to use system."

"I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers."

More Dell Unity XT pros

"The performance is valuable. The NVMe performance with VDI plays a big role. There is efficiency of the array and replication between two sites. A lot of customers use Alletra for production and DR and do replication."

"The simplicity of use is great."

"It's easy to use."

"The reliability is very good."

"More deduplication and compression are valuable because capacity matters."

"Alletra has helped us reduce time spent on storage."

"The solution has been rock-solid since we've had it."

"It's really easy to use."

More HPE Alletra Storage pros

Cons

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

"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."

"The tool's portfolio is minimal. It is expensive."

"It is on the expensive side."

"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."

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"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."

More Pure FlashArray X NVMe cons

"They can certainly improve in terms of monitoring."

"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."

"We do a lot of VMware. It only integrates with VMware in one way, which is virtual volumes. I don't really have any visibility on anything else. From VMware, I can't look into Unity. From Unity, I can't look into VMware unless I am using virtual volumes, where they integrate together happily, but we are not using that. I would like better integration for non-virtual volume VMware use."

"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."

"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."

"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."

"If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great."

"It might be nice to have more integrated features instead of having everything as a separate module, like the networking. The networking is attached separately in the back. It would be nice if that was more integrated with less ports."

More Dell Unity XT cons

"We faced many problems with HPE Alletra 6000, and we did not understand whether it was because of some issue with the controllers or the disk."

"I need the protocol expected. I want them to include NVMe protocol in VMware compatibilities."

"I do not have any issues with it. It has been good for us. There are no cons that I see, and that is why we use it."

"The solution could improve the upgrades. In Brazil, it's difficult. The price is very high and it is not an easy process."

"Maybe they could just reduce the number of racks and the amount of rack space."

"I'd like to see a smaller chassis in the hybrid arrays."

"There can be more visibility and statistics for the customers to see. The customers would love to see AI."

"They are definitely going to start pushing more on MP for files. This was an area where HPE was not very strong, but now, with Alletra MP, it is going to be very strong. Most importantly, there is going to be the flexibility of moving compute and storage on Alletra MP. This flexibility will be very good."

More HPE Alletra Storage cons

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."

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

"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."

"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 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."

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

"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

"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."

"The license is not required, but we must renew the support every year, every two years."

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."

"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."

"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."

"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."

More Dell Unity XT pricing and cost advice

"Overall, it was good. It had a good price per gigabyte."

"It is reasonably priced."

"So far, so good."

"Its pricing is very competitive."

"There is a license. HPE Alletra uses a cloud-based model."

"The solution is expensive and can cost around five lakhs."

"Its licensing is good. Pricing-wise, there can be a little bit more flexibility. It would help to have different sizes. However, it fits into the budget that we have, so we are happy."

"It is fairly priced. It is in line with industry standard pricing and cost models."

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."
