Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

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 pricing of Pure Storage is all-inclusive; it is very fair, very easy, and the solution is a lot easier to install than the Dell EMC product."
"What I appreciate most about Everpure FlashArray is that it performs compression and deduplication fantastically."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"From an investment standpoint, the support staff I require for it is greatly reduced, so I don't have the in-depth requirements that I had on other products."
"The performance is great."
"Overall, the best returns on investment have been operational simplicity, reliability, and reduced management overhead."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"For me, right now, it is the best storage solution in the market, by far."
"Huawei OceanStor is stable."
"The technical support from Huawei OceanStor is good."
"The most valuable feature is the availability."
"I find the scalability features of OceanStor valuable. Additionally, installation is easy, and it only requires one person to install it. Maintenance is also easy and not a big issue."
"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."
"OceanStor's overall stability and performance are quite good."
"The pricing is very reasonable."
"The solution is easy to scale as needed."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"We have not had a good experience with the IBM device."
"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"Self-backup is the only feature lacking in this solution."
"The energy could be better."
"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."
"Configuration complexity and the tools available."
"We would like the solution to provide better documentation. It needs to be more transparent so that we can figure out how to troubleshoot."
"We did experience a little latency with this solution."
"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."
"In the future release, Huawei OceanStor should improve on what they already have. It is a good solution."
"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 read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"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."
"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"There is always room for negotiation."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"The best features come included without any additional cost."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"Overall, the solution's pricing was cheaper."
"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."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"It's roughly affordable."
"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"Huawei OceanStor is a cost-effective storage solution."
"The price of the license is quite low, so it's not something special or expensive."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
