EMC VNX 2500 or EMC Unity 400. Which one is the newer and better Storage and why?

Unity is the new generation of VNX boxes, some refer it to as VNX3. The old VNX 2500 is already EOL since Dec 2014. So in this case Unity 400 is newer and better.

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Customer needs are addressed effectively with collaborative sales and service support

Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

The Nimble CS-Series has proven to be reliable with 100% uptime

When we started the process of looking for a SAN vendor I had four primary criteria: reliability, performance, cost, and simplicity. We were really looking for a unicorn and were fully expected to have to make compromises in one of those areas. The Nimble CS-Series was recommended by our solutions provider, and we were blown away. Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime.

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

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

"The cost for Pure may be high, but the reliability and scalability make it well worth the money."

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

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

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

"The initial setup was extremely simple and straightforward."

"Overall stability is very good. It is a very stable solution."

More Everpure FlashArray X NVMe pros

"We can get almost real-time response times."

"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."

"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."

"The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations."

"We are satisfied with the technical support."

"The most valuable feature is the ability to provision storage from the CLI, versus having to go in and use the GUI every time."

"We put the Unity on one of the file servers and the backup performance improved quite a lot."

"It's a great product if you want something that just works, and works fairly well."

More Dell Unity XT pros

"The replication feature provides another functionality to protect your data."

"It is very stable even during multiple power failures."

"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."

"It would be a good choice for midrange businesses due to the performance/features and cost."

"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."

"The VNX 5700 provides a large number of features including the ability to work for both file and block as a unified array."

"The replicating of the entire storage unit to a different location was a very useful function."

"It is very stable, even during multiple power failures."

More VNX [EOL] pros

Cons

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

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"I would like to see replication and DR features in the next release of this solution."

"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."

"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."

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

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

More Everpure FlashArray X NVMe cons

"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."

"I would like better monitoring capabilities: more historical data with more insight into the performance for the database."

"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."

"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."

"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud."

"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."

"Dell EMC Unity XT should present a path or a roadmap on how they could put their products on the cloud. This would have some value for their current customers."

"The price of Dell Unity XT could improve."

More Dell Unity XT cons

"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."

"You need a lot of licenses in order to use this product, which makes the product expensive; the maintenance contract price also increases significantly every year."

"EMC wasn't able to fix the issue, so they had to stop using snapshots."

"Make major changes to the file services, Celera, do something like a lite version."

"As an entry level array, this is just right, but adding support for FAST-VP would be beneficial although that feature is available on the higher end VNXe3200."

"I do not recommend the Gen 1 VNX to anyone in this day and age."

"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."

"There were scalability issues, the scalability options are limited due to supported SSD."

More VNX [EOL] cons

Pricing and Cost Advice

"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."

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

"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."

"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."

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

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

More Everpure FlashArray X NVMe pricing and cost advice

"The solution’s pricing is competitive."

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

"Go with the virtual appliance versus the hardware."

"The solution is very expensive."

"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."

"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."

"We purchased a five-year warranty."

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

More Dell Unity XT pricing and cost advice

"Reducing dependency on JavaServer Pages (JSP) could improve the administrative overhead."

"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"

"Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."

"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."

"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

"While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."

The VNX range is older and is being phased out. I think you mean VNX 5200? That said the Unity 400 is the better investment as it is newer, cheaper to support, faster, and with higher capacity and bigger supported file system size.

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."
