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…

A solution with a simple configuration and good stability but it's quite expensive
Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

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

Pros

"The initial setup was really straight forward."
"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"The performance is very good."
"It has good stability for our company."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."
"Overall, Pure Storage FlashArray has never let us down in front of customers so far."
"Very efficient storage"
"It is easy to use, deploy, communicate and manage this solution."
"Huawei OceanStor is easy to manage."
"Huawei OceanStor is stable and reliable for storage solutions."
"This is a stable storage system."
"The initial setup was straightforward."
"We would buy the solution again without any hesitation."
"The most valuable feature is the flexibility in the rail, as it is hybrid storage and can be used for many different use cases, depending on what our customer requests."
"Huawei provides excellent and efficient support, and the product is a good price."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"So coupled with the simplicity, performance, and just absolute ease of use of the management of it, I don't know why anyone wouldn't buy it."
"The ratio between the physical storage and the storage we use is very high."
"It has a very good duplication rate; very, very good."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"It is consistently stable; haven't had a single issue with it."
"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."
"The most valuable feature is definitely the always-on data deduplication."
 

Cons

"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"There are a lot of things to improve."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I would not say anything because we still do not use Everpure FlashArray fully."
"Its data replication features work slowly for nodes."
"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."
"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."
"From a political perspective, there are issues selling Chinese brands to Western companies, as some may not be permitted to use them."
"The administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."
"The speed has room for improvement."
"We would like the solution to provide better documentation. It needs to be more transparent so that we can figure out how to troubleshoot."
"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."
"The interface look and feel could be improved."
"The front panel of the drive shelf doesn't always seat firmly."
"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."
"On the road map, I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"I would like them to come down in price."
"The management graphical interface needs more improvement."
"Replication and de-duplication could be better."
 

Pricing and Cost Advice

"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"It is cheaper than NetApp."
"Pure Storage has not helped us to reduce our licensing costs."
"FlashArray is expensive, but the quality justifies the price."
"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."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."
"This product value matches its price."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"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."
"The price of Huawei OceanStor should be less expensive. It is expensive at the moment."
"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."
"Overall, the solution's pricing was cheaper."
"The licensing is all-inclusive."
"Kaminario is very competitive on price. They also have a pay per TB model."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
