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.

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

"Processes that used to take 40 minutes to two hours can be completed in five minutes."

"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution's initial setup process is easy."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."
"ThinkSystem is a good offer and can work out well if you can work with it to fit the use cases that you have."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"The system has dual controllers but does not have a high level of resiliency built-in."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."
"We ran into some issues with the program at first and we had to work around those issues to fix our problems."

"It is really entry-level. In the next release, I would like to see more functionality."
"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."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"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."
"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."
"We have seen a reduction in total cost of ownership (TCO)."
"Pricing is moderate. It is neither cheap nor expensive."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"The price of the solution is not expensive."
"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."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"The pricing is fair and low compared to other products in this category."
"It is an expensive solution."
"The best thing about this solution is its price, which reduces our costs."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
