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.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

Reliable synchronous replication has protected our infrastructure and improved disaster recovery
I do not have anything else to add about how I'm using Lenovo ThinkSystem DE Series beyond what I have already discussed. I do not have comprehensive information about all the features, but I can say that we have obtained many performance benefits from the storage using SSD Enterprise disk. Regarding Lenovo ThinkSystem DE Series's AI capabilities, I think the best practice is to use it with double factor authentication and AI integration. I believe the accuracy and reliability of output for Lenovo ThinkSystem DE Series are very good, but I do not have detailed information; I would need to think deeply and try to understand more thoroughly on the web interface to provide more specific feedback. My advice for others looking into using Lenovo ThinkSystem DE Series is to seek a stable infrastructure with a standard price—not a high price, not a low price, but a standard price with high performance. My overall rating for this product is 10.

Quotes from Members

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

Pros

"You get what you pay for; it is expensive, but it really works, so I would really recommend using Pure Storage."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"Technical support is excellent. I've had very good responses from technical support. We had a couple of cases where we needed support. Some of the communications were purely over email and some has been an actual call to the service desk."
"This storage has to be the most well thought out and effective storage that I have had the privilege to work with."
"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."
"They are quite responsive and our local team was pretty good."
"The most valuable feature is its speed."
"The most valuable feature is it never goes down. We can expand and create volumes."
"The product's initial setup phase was good."
"It works very well."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"The most valuable features of VMAX are its performance and GUI interface."
"The solution is very easy to troubleshoot, it doesn't take long to deploy, normally comes with a three-year warranty, and has the most features if you compare it to other models."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"Lenovo ThinkSystem DE Series is simple to use"
"Lenovo ThinkSystem DE Series has impacted my organization positively, and I would estimate approximately 90% improvement."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"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."
"The solution's initial setup process is easy."
 

Cons

"I would like to see additional features like performance monitoring, configuring alerts, and the customization of alert thresholds."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"One improvement area is the eradication time delay."
"A three wave application or multi wave application synchronization would be an improvement."
"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."
"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."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"Improvements are needed in both partition recovery and scalability."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"There is room for improvement in the centralized administration."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"Its performance could be faster."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"The solution could be more scalable, although it suits our present needs."
"There could be a snapshot feature in the solution."
"Scalability on rack-mount servers is not as good as with Blade servers."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
 

Pricing and Cost Advice

"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"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."
"FlashArray is expensive, but the quality justifies the price."
"We feel that the pricing is fair and the licensing process was easy for both."
"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"We purchased a license to use this solution and we pay for the storage ourselves."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"It is not a cheap product."
"We have a five-year contract for providing support."
"The pricing is fair and low compared to other products in this category."
"The best thing about this solution is its price, which reduces our costs."
"The solution's price could be better."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"It is an expensive solution."
"The pricing for this solution is good compared to HP or Dell EMC."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
