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.

Uses a proprietary technology with simple interface and has easy deployment
If you are not generating a substantial amount of data, the available storage space might suffice, making scalability less of a concern. However, if your data generation increases and you require more storage, Huawei OceanStor offers solutions to expand your storage capacity. Expanding storage resources can involve additional costs and configuration efforts. Acquiring more storage solutions and ensuring their integration with your existing setup might require a significant investment of time and resources. While this process can be complex, it allows for seamless scalability as your data storage needs grow. I rate the solution’s scalability an eight out of ten.
Nabeel Sayegh - PeerSpot reviewer
Supercharges enterprise storage by way of highly optimized hardware, comprehensive data management and a feature rich interface.
During their early years, I was a member of Pure's Customer Advisory Board. In addition, when we first adopted Pure, they did not have replication GA yet. We got into their beta testing program and help them work out certain issues with that technology. One weakness I can say the array has, still to this day, is limited control on scheduling snapshots. Depending on the type of replication schedule you are building, you may or may not have control on specifying the start time of a given replication schedule. This is not a very big problem in the grand scheme of things, but something nonetheless that has bothered me about the scheduler in general. Another area for improvement would be automatic host alias creation. Other platforms such as EMC Unity/PowerStore will automatically detect the host name, create a alias for it and associate the logged in HBA's to it. Pure does not do this for you and as a result, requires manual configuration. This can be very time consuming especially when you are deploying a large number of new servers.

Quotes from Members

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

Pros

"On a scale of one to ten, I rate Pure FlashArray as ten."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"Everything, especially the VMs inside, is pretty fast."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Huawei OceanStor is stable and reliable for storage solutions."
"The solution is scalable."
"The most valuable feature is the flexibility in the rail, as it is hybrid storage."
"Huawei OceanStor utilizes a proprietary technology known as RAID 2.0. This technology sets it apart from conventional storage solutions. RAID 2.0 offers advantages over traditional configurations. OceanStor's user interface is very simple and easy to use, featuring a graphical interface that enables quick and error-free setup of the storage system. This interface ensures that users can configure the storage efficiently and without mistakes."
"The technology seems to be good, especially the performance on their all-flash storage."
"Huawei OceanStor is a good product. Its interface is very simple. The complexities we encounter with recovery points are gone. We just attach to remote storage, click the application, and it starts."
"Generally stable with good technical support."
"The most valuable feature is the availability."
"We consume less physical storage because of the solution’s deduplication and compression."
"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."
"The solution is very reliable."
"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"It gives us capacity planning."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"Data reduction and compression. Sub millisecond latency."
 

Cons

"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"They could add more support for file storage and different types of storage."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"There is room for improvement in the pricing of the product."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The solution could improve by having better integration."
"The user interface is not so user friendly."
"The technical support has been a let down for us. It's something the company has to work on. We haven't been satisfied with their level of service."
"The main concern is regarding the usability of the data storage."
"The upgrading process needs improvement. Deploy it and notify the customers when new versions and stuff comes out. I don't think they're doing that well."
"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity. The data store ran out of space, and Huawei had to send a new unit."
"The administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."
"I would like to see more iterations and direct integration with other solutions."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"There are a lot of things to improve."
"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."
"One requested enhancement yet to manifest is the scheduling of snapshot replications."
"The latest release contains bugs that shouldn't be in a production environment. Two incidents impacted our client, including hardware-related bugs. They need to be more cautious in testing before they release."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
 

Pricing and Cost Advice

"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."
"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."
"As far as the licensing costs, everything is included in the license."
"Our licensing fees are $500,000+ USD."
"Given its price, Pure is not the first option."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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'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 pay a monthly licensing fee for this solution. The price could be less expensive."
"Pricing is very fair."
"Huawei OceanStor is a cost-effective storage solution."
"The price of the license is quite low, so it's not something special or expensive."
"Huawei's prices are very good compared to those of its competitors."
"Overall, the solution's pricing was cheaper."
"Its price is affordable."
"The tool's pricing is competitive and affordable. It has the best possible pricing that we can get from Huawei. The prices are fixed and there are no additional costs."
"We feel that the pricing is fair and the licensing process was easy for both."
"Pure Storage FlashArray's pricing is very competitive."
"We have seen a reduction in total cost of ownership."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"We have seen a reduction in TCO."
"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."
"The price is reasonable."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
