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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The most valuable feature of this solution is its ease of use."
"It has benefited my organization because it has reduced time to insights."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"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."
"The most valuable feature of this solution is reliability."
"The most valuable features of this solution are its ease of use and performance."
"One of the most valuable features is the capability to switch between all-flash to hybrid, which have have actually done for one of our arrays. We started with the hybrid, with the limited if I'm not mistaken, and then over a period of time, we swapped all the hybrids with the SSDs. This was one of the big features because it gave us the capability to not stick with just one kind of media. Secondly, since it has sorted clustering, we were able to bring in the newer boxes and have it all clustered together. These were the two main features that we really looked into, which benefited our use case from an expansion/growth perspective. Another valuable feature is the ease of management."
"I can mix and match the drives, using older mechanical devices and the latest SFP drives in a single solution with different enclosures."
"Its feature set is superior to some of the other platforms."
"The setup is straightforward."
"Everything is sub-5 MS for us. What I've found is that, with all-flash, when an app from my business is slow, I pretty much know it's them and not me. It leads to a performance conversation that has really hit an interesting threshold point where we are better than what they need. So now we get to have that "refactoring your application" conversation a lot quicker because now the performance on the infrastructure side isn't in question anymore."
"The solution is stable."
"The interface is easy to use which makes the product user-friendly."
"Technical support is very good. I do use it from time to time and it's always excellent."
"To be programmatically administered is huge, it is one of the key features that we like about it."
"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."
"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."
"Scalability is good."
"We use replication for disaster recovery (DR), making our DR process much easier."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
 

Cons

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Maybe the price can be reduced since the solution is very expensive."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"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."
"We need better data deduplication."
"In the future, I would like to see integration with enterprise backup systems."
"While the scalability is good, there are certain limitations."
"The SC Series doesn't support NVMe storage."
"Compellent comes in the form of a component that's not true of a unified storage platform."
"In the future, I want any box that comes on-premises to have the provision to integrate with cloud storage."
"I would like to see an integrated key manager in the controllers. Currently, it's an external product. It would be nice to have the option of having a built-in key for self-encrypting drive features."
"It would be helpful if the solution offered higher performance, at least on the back end."
"The lack of reporting would be the main issue."
"I would like to have 100% functionality through the web app."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"It is expensive, and the pricing could be better."
"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
"We would like to see more advanced integration capability added to this solution."
"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"Dell Unity XT’s price needs improvement."
"The initial setup is not so straightforward if you don't have experience with storage arrays."
 

Pricing and Cost Advice

"Given its price, Pure is not the first option."
"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."
"The licensing is on a yearly basis."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"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."
"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."
"We have the basic license for the use of this solution and it is a permanent license. The overall cost could be less, it is expensive."
"The pricing of Dell EMC Compellent is competitive."
"We were able to afford two tiers of flash storage at a price where the competition was giving us one tier or just a handful of discs."
"It is one of the most cost effective systems for us. We have been able to run it longer than most, getting the most benefit and money out of it."
"We have found the solution to be affordable."
"There are costs involving the solution, vendor fees and product safety which are additional."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"The SC Series was priced fairly. I wouldn't call it either expensive or cheap because we had a very tight budget, so if they were able to fit in that type of budget, they met our expectations."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"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."
"We have to apply for a license for each system."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"The price is good for commercial grade storage arrays."
