Featured Reviews

Eugene Hemphill - PeerSpot reviewer
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.
Steven McClendon - PeerSpot reviewer
Superior platform with excellent snapshots and cost-saving auto-tiering
I'm a big fan of the SC Series platform. Its feature set is superior to some of the other platforms. The snapshots on SC are excellent, allowing for multiple snapshot schedules for any one system. The auto-tiering functionality intelligently moves new data to the highest performance tier and then progresses it down to less expensive tiers over time, providing cost savings for customers.
Syed Habib - PeerSpot reviewer
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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The high availability of the product is the most valuable feature."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Overall stability is very good. It is a very stable solution."
"The most valuable feature of this solution is its ease of use."
"The solution is very straightforward to set up."
"What is most valuable about the Dell EMC SC Series system was its reliability."
"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."
"It is suitable for small or medium businesses."
"The most valuable feature is the speed for the end-user."
"The Dell support is helpful and the response is quick. The agents' knowledge is very good."
"The product offers good performance and is quite powerful."
"It has been one of the most stable products in our data center."
"I find this version to be more budget-friendly compared to products from other vendors. This aspect greatly benefits my customers. It's highly advantageous due to its affordability. The operational aspect is also noteworthy. Additionally, its availability and performance are commendable. The speaker are also equally powerful."
"Veeam Backup integration: Veeam is the defacto standard for backing up of virtual environments."
"Dell Unity XT offers data integration features."
"I like the integration into VirtualCenter. I used to have to add LUNs manually, then scan them in and format them. It does that all for you, all in one, immediate deployment of LUNs."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"It is very stable."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
 

Cons

"There is room for improvement in the pricing of the product."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Adding some functions to the product would be beneficial."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"They could add more support for file storage and different types of storage."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The cost of the solution could be better."
"It's not very efficient anymore. There are better products out there."
"I would like to see higher compression, dedupe, faster I/O, and bigger drives."
"We have seen some degraded throughput with mixed workloads. We have been working with Dell EMC to correct some of these latency issues."
"I don't think the solution is very scalable."
"The price could be improved."
"Technical support should respond more quickly because the turnaround time is very high."
"What I understand is that this is a 13 year old architecture, so it has lived its life and they're phasing it out. Honestly, we were initially struggling with the integration with VMware (but it was fixed with the VMware 6.5) and, then, it was around a 10GB network. At that time, it had the longevity to go to 100GB as well. It got us thinking about, when we go into the containerized architecture, what do we need to do to fix the infrastructure?"
"Dell could improve Unity XT by adding support for NVMe."
"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."
"A customer had to buy VMX because Unity didn't have WORM."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."
"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."
"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."
"Compression and block deduplication on non-all-flash solutions."
 

Pricing and Cost Advice

"Given its price, Pure is not the first option."
"The support cost per array is about $20,000 a year for 24/7 support."
"As far as the licensing costs, everything is included in the license."
"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."
"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."
"With VMware, we pay $300,000 annually."
"The licensing is on a yearly basis."
"It has a good price point and offers some value-added enterprise features."
"The pricing is reasonable, but it is expensive."
"The pricing of Dell EMC Compellent is competitive."
"It's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."
"This product is too expensive compared to others, and I don't see any value in using it."
"We have reviewed many platforms over the years. It is probably the best solution for its value."
"Compared to other solutions out there, it's affordable."
"Pricing depends on varying life cycles."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"From a pricing perspective, this solution is comparable to others on the market."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"The price is good for commercial grade storage arrays."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
