Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.
Mir Gulzar Ahmed - PeerSpot reviewer
Offer reliable storage and servers, and their libraries are also very reliable
The only weakness is that the internal cache is low, starting from 16 GB to 64 GB. Even the larger models only have 128 GB. In comparison, NetApp storage starts with 64 GB of cache or storage memory, and their enterprise models have 128 GB or more. Hitachi doesn't offer 16 GB of cache for storage, and their options start with higher amounts like 128 GB. So, if a customer needs more cache or storage memory, the Eternus DX series is not the right solution. However, if they need a cheaper storage solution with enterprise scalability and reliability, they should consider Fujitsu. There are no additional features needed, but the software products for Eternus DX can become very expensive when used in combination. For example, the software stack for replication DR from mirroring and remote data replication is costly. Even with the complete software suite, it remains cheaper than NetApp, but the prices for individual components like deduplication, local copy, and remote copy could be reduced. It's worth noting that deduplication in Fujitsu and Hitachi is not free of cost, unlike NetApp, where it is free of cost.

Steady performance, responsive support, and high availability
If we add a shell, the scalability depends on a legacy protocol and not the IBM FlashSystem 9100 NVMe which is a setback. At the previous bank, I worked at we had approximately 9,000 users. We are using the solution at its full capacity. I rate the scalability of IBM FlashSystem 9100 NVMe a seven out of ten.

Quotes from Members

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

Pros

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The solution is scalable."
"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."
"One of the best features is the support, which is excellent."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"Technical support has been helpful and responsive."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Overall stability is very good. It is a very stable solution."
"Fujitsu offers a range of scalable products within the Eternus DX series, including all-flash, hybrid, and large-scale storage options."
"The features I find most valuable include its use for storage and performance."
"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."
"Its ease of use, performance, and hardware compression is very useful feature."
"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."
"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."
"It's easy to use, has good stability, and many features."
"The high performance and high availability improved our overall processes."
 

Cons

"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."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"I'd like to see the product implement active replication for vehicles such as VMware."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The only weakness is that the internal cache is low."
"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."
"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.""
"The solution's compression needs to be improved, as it's not the best."
"In the future, the limitation is upgrading the same storage by adding a shelf to the desk. There is a limitation in the backend connection between the storage and extended shelf."
"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."
"The support could be better."
"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."
"I'd like to be able to connect to tape drives behind the storage device to back up the tape if need be. We have all of our storage running in all-flash, and we make a copy on tape. Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex. We want IBM to add a feature where we could install a tape into the storage so that we can connect it through a single pane of glass. We'd like to have a feature in the IBM flash storage system so that we can connect backup tape drives through the IBM storage system and we can manage the backup tape from the storage system."
 

Pricing and Cost Advice

"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."
"Given its price, Pure is not the first option."
"Our licensing fees are $500,000+ USD."
"With VMware, we pay $300,000 annually."
"The product is expensive."
"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"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."
"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"The DX series is a very cost-effective solution compared to any other storage system sold by any vendor. It starts at $16,000, and no one else can provide a storage system at that price."
"The solution is priced well."
"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."
"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."
"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."
"The solution's price is competitive."
"The tool's pricing is competitive."
"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."
"Compared to its competitors, IBM's offering is the most cost-effective."
