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 is very straightforward. You simply plug it in and turn it on."
"This solution has improved the way our organization functions through its reliability and consistent platform for storage and has helped us to simplify storage because the management tools make everything a lot easier."
"The availability and ease of use are the big features."
"The Direct FlashArray stands out as one of the best features in the market. The Pure1 storage management lets us see the details about utilization and everything else for all 40 storage boxes in one place."
"Pure is simple to set up and manage on a day-to-day basis."
"Once it's set up, it just runs on its own and only requires the occasional checkup."
"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"The solution is easy to scale as needed."
"It is easy to implement or install the tool."
"Huawei provides excellent and efficient support, and the product is a good price."
"Being a Huawei product, initial setup was easy and not difficult at all."
"The initial setup was straightforward."
"Huawei is much cheaper compared to Dell, offering a competitive price that makes companies consider their options."
"We get a quick response in case any component defaults. We have seen the benefits mostly."
"We deployed Huawei OceanStor because we had some problems increasing the number of users on our database and were suffering from slowness and downtime, and after implementing All-Flash now most of our data-intensive transactions are sitting under All-Flash and we've gotten quite a good response from our users."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"The ratio between the physical storage and the storage we use is very high."
"The GUI is very straightforward and easy to use."
"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."
"Looking at what changed at Kaminario the last couple of months (and the last couple of years, for that matter) I’m certain we’ll see a lot of great innovation from Kaminario in their upcoming releases."
"Image backups of our production servers that used to take hours now take minutes."
"It is consistently stable; haven't had a single issue with it."
"The speed and, for us in particular in what we're doing, the data de-duplication."
 

Cons

"It would be beneficial to have a health check command that can be run from the CLI to ensure that all hardware components are functioning properly rather than having to enable remote access and connect to support for a health check."
"In the next release, I would like to see file-level encryption."
"We have not seen a reduction in our TCO nor have we seen ROI."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"CIFS and SMB Shares cannot be mounted directly."
"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"The price is too high."
"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."
"The main concern is regarding the usability of the data storage."
"The GUI is the only thing I would like to see improved, and the user interface is not so user friendly."
"Huawei OceanStor could improve the deployment stage, configuration, and documentation."
"Huawei technical support was not needed to fix production issues, but I got in touch with them once, and it wasn't very good because we did not get the 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."
"The management is not a good feature in all of Huawei products. It's not easy or simple. Huawei has some problems with management and handling storage information from one interface."
"I would like to see more iterations and direct integration with other solutions."
"The tool's performance is slow for DBs. We plan to move from Huawei OceanStor to Pure Storage. Its customer service is not good."
"I would like them to come down in price."
"The management graphical interface needs more improvement."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"Replication and de-duplication could be better."
"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"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."
"The front panel of the drive shelf doesn't always seat firmly."
 

Pricing and Cost Advice

"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"Pure Storage has not helped us to reduce our licensing costs."
"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"The price is very reasonable when compared to other solutions."
"Pricing is very competitive, and it's better than other competitors."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."
"It's roughly affordable."
"This product value matches its price."
"Huawei OceanStor is a cost-effective storage solution."
"The product is cheap."
"Its price is affordable."
"The price of the solution could be less expensive. However, there are not any licensing costs."
"Overall, the solution's pricing was cheaper."
"Kaminario is very competitive on price. They also have a pay per TB model."
"The licensing is all-inclusive."
"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."
"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."
