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

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

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

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

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

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"If a company is looking for an All-Flash Tier and they need extreme performance for individual workloads, Pure's the way to go, over something like a SolidFire."

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

"The administration and the stability are very good."

More Everpure FlashArray X NVMe pros

"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array."

"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."

"We're using Dell EMC Unity as our primary storage for our production and for our DR site, we've had no performance issues with it whatsoever and we're using it for everything."

"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."

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

"The most valuable feature is the integration with vCenter."

"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."

"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."

More Dell Unity XT pros

"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."

"It is a good product with a simple setup and easy administration."

"Customer service is top-notch with a dedicated sales and technical resource who are familiar with your environment and spend a lot of time understanding your business needs."

"EMC storage has the best performance and functions."

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

"The stability of the hardware, and its ability to manage millions of IOPS, provides great comfort to system administrators, IT managers and CIOs."

"I think it's a good solution; it has many benefits and features that are of interest for many customers."

"I have worked on CLARiiON and all series of VNX."

More VNX [EOL] pros

Cons

"The software layer has to improve."

"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."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"Maybe the price can be reduced since the solution is very expensive."

"The software layer has to improve."

"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."

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

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

More Everpure 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 would be better if there were more integrations."

"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."

"If I can connect to my Unity through my iPad or my cellphone to check everything is okay and view the information via a dashboard, I would like to have secure mobile connectivity going forward."

"Dell Unity XT’s price needs improvement."

"In terms of what could be improved, I would say its capacity and its connection."

"Licensing costs could be reduced."

"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."

More Dell Unity XT cons

"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."

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

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

"I think one area where we would like to see improvement is better deduplication and compression."

"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."

"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."

"With this product, the licensing software and capacity are very expensive."

"HP EVA and once NetApp, but they both had slow performance and a lack of features so we switched."

More VNX [EOL] cons

Pricing and Cost Advice

"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."

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

"The licensing is on a yearly basis."

"The support cost per array is about $20,000 a year for 24/7 support."

"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."

More Everpure FlashArray X NVMe pricing and cost advice

"The price is very reasonable."

"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."

"This solution offers great pricing."

"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."

"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."

"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."

"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."

"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."

More Dell Unity XT pricing and cost advice

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

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

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

"The initial pricing and licensing are reasonable. 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."

"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."

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

Unity series is re-engineered VNX, so the Unity is newer … it makes better use of flash, active – active , dual controller mode; better price point , configurations solid upgrade from the VNX

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.
