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 cost-effectiveness are maximized with seamless setup and significant ROI
I use Lenovo ThinkSystem DE Series to replace the old storage in our infrastructure. Additionally, I use it in customer infrastructures to migrate from the old storage to the new one On the M storage, I find the best features to be deduplication and compression. On the DE storage, the most…

Complicated deployment and poor support persist, affecting overall satisfaction
The deployment process of Lenovo ThinkSystem DM Series is very complicated compared to previous GUI systems. Many customers have lost data while configuring it, indicating a need for improvement. The after-sales service is also very poor. Furthermore, it does not offer basic features like deduplication, and the service is generally considered to be very bad.

"The solution is very easy to set up."
"Its initial setup process is easy."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"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."
"Lenovo ThinkSystem DE Series is simple to use"
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions, and it's also easy to use."

"The licensing model needs to be revisited. It needs to be simplified."
"Lenovo could have a wider variety of storage solutions in the NAS space."
 

Pricing and Cost Advice

"Pricing is moderate. It is neither cheap nor expensive."
"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."
"The pricing is reasonable."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"There are no licensing fees or other costs."
"Cost-wise, it's been very effective."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"We have a five-year contract for providing support."
"The pricing is fair and low compared to other products in this category."
"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."
"It is an expensive solution."
"The pricing for this solution is good compared to HP or Dell EMC."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The best thing about this solution is its price, which reduces our costs."
"The solution is highly-priced."
"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
"The price of the Lenovo ThinkSystem DM Series is good."
"The solution's pricing is similar to Dell and HPE."
