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

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 most valuable feature of this solution is the support."
"We are finding the TCO of flash to be lower than SSD implementations."
"It's simple, powerful, and ready to use."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"The most valuable features would be its performance, retrieval, recovery, and backup, and it meets the customer's expectations."
"What I appreciate most about Everpure FlashArray is that it performs compression and deduplication fantastically."
"The first set up we had was really straight forward and simple."
"The deduplication and compression rates are beyond impressive."
"Huawei OceanStor is designed with built-in high availability features, such as fault tolerance, ensuring consistent data access and minimizing downtime."
"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."
"The setup and the price are the most valuable and not the features related."
"The most valuable feature is the availability."
"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 OceanStor is stable and reliable for storage solutions."
"The pricing is very reasonable."
"Huawei OceanStor has the capability of SSDs, high-performance disks, and higher disk support."
"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."
"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."
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"Kaminario allowed us a solid state solution with marginal incremental cost."
"Logic/software management"
"Our holdup was disk I/O, so we did a PoC with Kaminario and we reduced build times down to fifteen minutes for a full build from two hours."
"From my perspective, it is a huge success fulfilling everything we needed and more!"
"Improved performance by more than 50x on our application."
 

Cons

"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."
"I find the pricing of Everpure FlashArray to be quite high compared to other storage solutions; however, the reliability and features are commendable."
"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"I feel like there is too much automation; the user doesn't have any manual input."
"I would like to have support available in Spanish."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"From a political perspective, there are issues selling Chinese brands to Western companies, as some may not be permitted to use them."
"Its storage capacity could be better."
"The main concern is regarding the usability of the data storage."
"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 duration of the built-in snapshot technology must be improved."
"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."
"The product must improve the local technical support in China."
"Customer support is very good but if you want support and you don't have SNS switches as well, the complete solution is not there."
"The management graphical interface needs more improvement."
"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."
"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"I would like them to improve the look of the product’s external casing and shelves."
"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."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
 

Pricing and Cost Advice

"The price of the solution can be a bit expensive. There is an additional fee for support."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"Pure Storage has not helped to reduce our HANA licensing costs."
"The price is reasonable."
"The solution is expensive."
"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."
"It could always be lower, but it's okay."
"Pure Storage FlashArray is expensive."
"This product value matches its price."
"The price of the license is quite low, so it's not something special or expensive."
"We pay a monthly licensing fee for this solution. The price could be less expensive."
"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 priced very well but is a bit complicated."
"Huawei's prices are very good compared to those of its competitors."
"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 licensing is all-inclusive."
"Kaminario is very competitive on price. They also have a pay per TB model."
"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."
"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."
"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
