Cristian Ion - PeerSpot reviewer
Senior Information Technology Engineer at Eta2u
All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services
The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

Reliable solution offers good IOPS and energy efficiency
Huawei OceanStor is mainly used as a SAN in our organization's data management process Huawei OceanStor offers good IOPS and is reliable and energy-efficient. It provides a decent device for data scalability. Based on what we were quoted, the stated capacity was not a true reflection of the…

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"The most valuable feature is its data reduction."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"I would recommend Pure Storage FlashArray to other users because, first, the speed that I get with Pure Storage FlashArray is not remotely possible with any other product at this price range, and second, the support is absolutely fantastic."
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."
"It helps to simplify storage because it has an easy front-end to access everything."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"The technology seems to be good, especially the performance on their all-flash storage."
"We get a quick response in case any component defaults. We have seen the benefits mostly."
"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"Huawei OceanStor offers good IOPS and is reliable and energy-efficient."
"OceanStor's overall stability and performance are quite good."
"OceanStor brings to us the best performance as storage for our virtualization cluster, allowing a better performance in the apps that need to manipulate a huge amount of data."
"The management of the solution is easy and documentation is very much simple, so if someone is new to the solution all they need to do is follow the documentation and they can handle the product with ease."
"Great value for money."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"I have been primarily working with storage and have not fully explored other areas, but there is some room for improvement when it comes to performance reporting."
"When creating a support case, visibility should be extended to others involved in assisting."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"I would love to see a true one click upgrade solution."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"Supporting software is one of them and the integration with mainstream solution technologies could be better."
"They should introduce a feature to Huawei OceanStor similar to a storage controller, allowing for seamless integration of additional storage modules."
"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 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."
"The speed has room for improvement."
"The configuration process is very complex, and the proprietary tools/software available for configuration are kind of tricky to install and run."
"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."
"Configuration complexity and the tools available."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"It's priced higher than the market."
"Its price is almost double than any other flash storage solution."
"There are no fees for licensing. The hardware is paid for only once."
"It is light years beyond anything else with the same price point."
"The best features come included without any additional cost."
"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."
"The price, in general, is around $100,000, however, I know it costs more."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"Its price is affordable."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"It's roughly affordable."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"Huawei OceanStor is a cost-effective storage solution."
"Huawei OceanStor is priced very well but is a bit complicated."
"Huawei's prices are very good compared to those of its competitors."
"We pay a monthly licensing fee for this solution. The price could be less expensive."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
