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.

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 stability and performance are the best things about the solution."
"In Pure Storage FlashArray, the dedupe and compression are excellent, and performance is good too."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"Having an intuitive user interface to get things running is great."
"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."
"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"Generally stable with good technical support."
"It is easy to use, deploy, communicate and manage this solution."
"The initial setup was straightforward."
"The pricing is very reasonable."
"Huawei is much cheaper compared to Dell, offering a competitive price that makes companies consider their options."
"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 most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"The most valuable feature is definitely the always-on data deduplication."
"Provisioning large numbers of virtual desktops has sped up considerably."
"Rocketing IOPS results in performance we don't have to fixate on, so we can instead focus efforts on other layers in the stack, knowing that our SAN layer is lightning fast, with capacity to spare."
"I think this product hits all the big features of all the SANs that are out there, all the storage vendors that are out there and more."
"Inline compression"
"Go with it. I tell people all the time they need to take a serious look at it."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
 

Cons

"It would be beneficial to have a separate pricing point for environments with lower performance requirements or less workload."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"When creating a support case, visibility should be extended to others involved in assisting."
"The best way to improve Pure Storage FlashArray is the active DR because that can get very confusing, especially when you're trying to test a failover and replicate back; better instructions on how to do that would help because we actually lost an entire volume when we were testing out some stuff as the fingerprint got reinitialized, and when you replicated back, it didn't know about that volume, causing a failure in that process."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"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."
"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."
"OceanStor could use improvement with configuration and synchronizing with other vendors."
"They should introduce a feature to Huawei OceanStor similar to a storage controller, allowing for seamless integration of additional storage modules."
"I would like to see more integration features with different platforms."
"In terms of marketing, they need to improve by putting more effort into making people aware of their products, especially in our region."
"Supporting software is one of them and the integration with mainstream solution technologies could be better."
"In the future release, Huawei OceanStor should improve on what they already have. It is a good 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 solution could improve by having better integration."
"I'd give it a perfect rating if I could push it to 300,000 IOPS like they promote; we just haven't been able to push that many IOPS out of our system."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."
"I would like them to improve the look of the product’s external casing and shelves."
"Replication and de-duplication could be better."
"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."
"The management graphical interface needs more improvement."
