Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

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.

Quotes from Members

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

Pros

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"What I really like about this program, is that it is easy to use and easy to configurate."

"The latency is good."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"The most valuable feature of this solution is reliability."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"It has good, reliable, fast storage."

More Pure FlashArray X NVMe pros

"It is a very stable solution."

"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."

"It's easy to use, has good stability, and many features."

"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."

"The most valuable feature is the speed."

"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."

"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."

"Its ease of use, performance, and hardware compression is very useful feature."

More IBM FlashSystem 9100 NVMe pros

"The solution offers very good reliable systems and storage for our clients."

"We are satisfied with the stability."

"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."

"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."

"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."

"The FlexClone feature is the solution's most valuable aspect."

"The value we derive from using it is greater than other alternatives like HPE and Dell."

"Ability to cluster two storages together with HA availability."

More Lenovo ThinkSystem DM Series pros

Cons

"Maybe the price can be reduced since the solution is very expensive."

"Adding some functions to the product would be beneficial."

"There are some challenges with data encryption and reduction."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

More Pure FlashArray X NVMe cons

"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."

"The support could be better."

"The solution's compression needs to be improved, as it's not the best."

"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."

"The solution's compression needs to be improved, as it's not the best."

"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."

"Other vendors have included a block and file system. IBM doesn't include a file system. And yet, it's very necessary for all organizations' networks to have file systems. We have other systems for the file system, however, ideally, we would like to have one system with these features."

"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""

More IBM FlashSystem 9100 NVMe cons

"The solution should change the licensing model and allow customers to choose features based on their requirements."

"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."

"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."

"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."

"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."

"Lenovo could have a wider variety of storage solutions in the NAS space."

"The licensing model needs to be revisited. It needs to be simplified."

"Lenovo ThinkSystem DM Series is not stable. If I have sold fifty boxes, about fifty percent of them experienced failure."

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"As far as the licensing costs, everything is included in the license."

"The licensing is on a yearly basis."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"Given its price, Pure is not the first option."

"We pay approximately $50,000 USD per year in licensing fees."

More Pure FlashArray X NVMe pricing and cost advice

"The solution's price is competitive."

"Compared to its competitors, IBM's offering is the most cost-effective."

"The price of the FlashSystem 9100 NVMe is reasonable."

"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."

"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."

"The tool's pricing is competitive."

"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."

More IBM FlashSystem 9100 NVMe pricing and cost advice

"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 solution is highly-priced."

"The solution's pricing is similar to Dell and HPE."

"The price of the Lenovo ThinkSystem DM Series is good."
