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.
TOLGA ALNIAK - PeerSpot reviewer
Offers ransomware protection for files stored on servers
Data processing is the most important feature. We are using Huawei OceanStor Dorado, which employs SSD storage on the hardware side. No reported performance issues or improvements are required for our systems because all of the systems run on memory on the host side. The Oracle data and Oracle virtual machines also operate from memory. Additionally, we use Oracle for patching systems, with all data residing in memory. There is some latency during backup times, typically at night, but this is acceptable for us. These latencies occur outside of office hours, so they do not impact our operations during normal times when there is no noticeable latency.

Quotes from Members

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

Pros

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"The database workloads are pretty fast because I frequently move data from here to there."
"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."
"Overall stability is very good. It is a very stable solution."
"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 latency is good."
"One time, we had a drive fail and we were notified before we even saw it on the device."
"Customers are most impressed with SC's provisioning because you don't need to buy a large amount of storage upfront. It's pay-as-you-grow. It also has solid compression and duplication features."
"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."
"The process of reallocating data from fast disks (SSD or SAS) to slow disks (SATA) gives you better performance and better use of resources."
"The performance benefits weren't surprising, we expected that. What we didn't expect were the densification benefits that we got out of going all-flash. We're able to put more applications on the arrays because of how all-flash performs. The way some of the application profiles have responded to all-flash has been really pleasing."
"The Dell support is helpful and the response is quick. The agents' knowledge is very good."
"The solution has a wide variety of valuable features. The data progression works well. We use the snapshot functionality quite a bit and really like it."
"It is easy to use, expand the hard drives, add storage, and set up replication."
"The product has the best compression and encryption features. The most valuable features I have found in the tool are its performance and cost-effectiveness. While Huawei OceanStor Dorado may not always be chosen for its features compared to other brands like Dell, HPE, etc., it is often selected due to its affordability. Customers opt for Huawei OceanStor Dorado primarily because it offers similar performance features as other brands at a lower cost."
"There are plenty of features available in this solution."
"The most valuable feature for me is that it deduces better, whereby it can be assigned six times the usable capacity, depending on the nature of the data."
"The primary factors that make Huawei OceanStor Dorado Series highly valuable to us are its competitive pricing, exceptional performance, and stability."
"The fast performance and reasonable pricing of Huawei OceanStor Dorado are the main reasons we sell them."
"The deduplication features and the graphical user interface (GUI) of the solution are the most valuable to me."
"The most valuable features are the five chips architecture and the purpose-built NVMe hard disk drive. Additionally, the IOPS feature is good."
"The most valuable features of the solution are SmartMigration, HyperReplication, HyperSnap, HyperCopy, HyperClone, SmartPartition, and SmartCache."
 

Cons

"The tool's pricing is higher than competitors."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"In terms of what needs improvement, the dashboard and management could be simplified."
"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."
"Adding some functions to the product would be beneficial."
"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."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"I would like to have 100% functionality through the web app."
"The initial setup is somewhat complex and should be made simpler to do."
"Dell could improve the upgrading process."
"The connection should be better integrated with the network to offer a better view of the system."
"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."
"The tool's pricing is high and not suitable for medium companies."
"This product should be a lot more user-friendly."
"We have seen some degraded throughput with mixed workloads. We have been working with Dell EMC to correct some of these latency issues."
"The product's current pricing model involves over 12 different licenses, which can be complex. Simplifying the process would enhance the overall user experience."
"They should add a feature to the platform to help us manage storage communication with one of the vendors."
"There could be local support services available for the platform. Additionally, they should provide a bundled license, including all protection and encryption rules."
"Huawei should provide new security features, such as blocking ransomware sites and improving detection. Currently, we receive updates from HQ in China; there are instances where hackers may infiltrate network sites and encrypt our data."
"The product should be better aligned with the virtual environments"
"Some customers have reported not understanding how the immutable part can be unlocked."
"If they implement a backup solution directly into the OceanStor then it will be a valuable feature."
"There are some limitations to this product because they do not have unified storage."
 

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."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"The support cost per array is about $20,000 a year for 24/7 support."
"With VMware, we pay $300,000 annually."
"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."
"The licensing is on a yearly basis."
"The scalability seems a bit more expensive than even buying a brand new one so far. That has been kind of a drawback."
"There are costs involving the solution, vendor fees and product safety which are additional."
"Compared to other solutions out there, it's affordable."
"Support typically depends on the array. It can range anywhere from $7,000 to a couple of hundred thousand dollars."
"We have found the solution to be affordable."
"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."
"It's a very affordable solution."
"It's not easy to receive an upgrade license of Huawei OceanStor Dorado. It's easy to buy OceanStor with several features, but when you want to add on features later it's not easy. I had some problems."
"The price of the solution is reasonable. There is not a vendor that offers an All-Flash Storage Array at the price of Huawei OceanStor Dorado. The other solutions are approximately 50% higher."
"The pricing is very competitive."
"We usually recommend our customers choose advanced licensing and enterprise companies are more inclined to choose this solution because it is more cost-effective than competitors."
"Huawei OceanStor Dorado has a competitive price compared to other solutions."
"The price of Huawei OceanStor Dorado is very inexpensive, it cost approximately $5 per gigabyte."
"The price of the solution is competitive compared to others, such as Dell EMC and Hitachi. I believe the reason they are providing a discount is they want to increase their penetration into the market."
"You need to pay for the license."
