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.

Improves cost efficiency and significantly while boosting workload performance

We have realized several benefits from using Dell PowerStore; we migrated to the current Dell PowerStore models from tiered storage, and now we're using all flash. The dedupe and compression has been a big benefit for us versus the old storage that it was running, and we've seen the performance of all flash for our storage services. My company finds particular features within Dell PowerStore valuable, primarily the cost benefits for the performance that we get out of the platform. We've definitely seen the benefit on that side of it, including the cost per terabyte, and the support from Dell has been excellent as well. We haven't had any issues with it, so it's been very reliable as a platform for us. The performance metrics I use to measure success with Dell PowerStore are all IOPS and throughput. We are not using it with AI workloads on Dell PowerStore, so it's primarily just customers running IaaS, however, it is important that it's reliable and performs well, and we get that from Dell PowerStore. Dell PowerStore has supported growth and operational success for my business; a key driver at the moment is consolidation, and the dedupe and compression ratios allow us to standardize on a single platform. This has helped improve our operational metrics and overall operations, as we now have only one vendor to support and one set of storage arrays to manage. We have a very clear path into support and escalation if there is an issue, and we are not dealing with multiple vendors.

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."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"I appreciate the performance."

"The most valuable features of this solution are its ease of use and performance."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"The database workloads are pretty fast because I frequently move data from here to there."

"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."

"One of the best features is the support, which is excellent."

More Pure FlashArray X NVMe pros

"The management portal is particularly user-friendly."

"If I were giving advice to another company looking at Dell PowerStore, I would say that you cannot go wrong with Dell, as the sales and support teams are always top notch."

"We have implemented Dell PowerStore for small sites needing mirrored storage. To ensure high availability, the storage is set up in two different locations, possibly in the same building but far apart."

"The data encryption is good and available in a standard license. There are snapshot and backup capabilities."

"Dell PowerStore's valuable feature stems from an area named Metro Volume, which is quite simple to implement. The feature works fast and is good."

"I really appreciate the management and the management console of Dell PowerStore along with features such as deduplication."

"This solution is very useful to us as we use it internally for all of the services that we need. We use it as a lab and we showcase new technology to the customers and how it can help them going forward."

"PowerStore is robust compared to the previous models like Unity, and it provides excellent compression and deduplication."

More Dell PowerStore pros

"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."

"IBM FlashSystem 9100 NVMe is one of the leading storage systems in the world...I rate the solution's stability a ten out of ten."

"The most valuable feature is the speed."

"The high performance and high availability improved our overall processes."

"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 of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."

"IBM FlashSystem provides the same software on each box, including virtualized solutions."

"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."

More IBM FlashSystem 9100 NVMe pros

Cons

"It is on the expensive side."

"We need better data deduplication."

"The UI for this solution needs to be improved."

"The software layer has to improve."

"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."

"I'd like to see the product implement active replication for vehicles such as VMware."

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

"We've seen that when we create a POD in synchronous mode, it increases the latency."

More Pure FlashArray X NVMe cons

"AI will be a challenge and we must manage different kinds of data with more performance and security."

"I do not have any current pain points that I would like them to fix, although we did have one issue when an update stopped the phone-home solution, however they fixed that via support."

"The solution only does thin provisioning."

"If I could improve the product in any way, I would add features that make it look nicer compared to the DisplayPort."

"The UI should be a little more user-friendly to manage."

"If I could improve Dell PowerStore, I would suggest that integrations into backup platforms be a little more streamlined."

"There seems to be a lack of a price range in the small company, small medium company segment."

"Dell PowerStore currently only allows us to copy data from our main production system to the disaster recovery site."

More Dell PowerStore cons

"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."

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

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"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.""

"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."

"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."

"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."

"The pricing should be more competitive."

More IBM FlashSystem 9100 NVMe cons

Pricing and Cost Advice

"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."

"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."

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

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The product is expensive."

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

"With VMware, we pay $300,000 annually."

More Pure FlashArray X NVMe pricing and cost advice

"When we compared it with the other solutions, the pricing of PowerStore was equal. The pricing is good."

"Dealing with the licensing part of the product is very simple, especially considering the fact that we don't have many licenses associated with the tool."

"I rate the price of Dell PowerStore a seven out of ten."

"In terms of licensing, my organization has Dell Technologies End User License Agreement (EULA), but I don't know exactly how it works, though it is a big bundle of licenses for Dell Data Domain, Dell EMC Unity XT, Dell PowerStore, Dell ECS, and all such kinds of storage arrays."

"In the pricing and licensing department, the product is always too expensive."

"The software features are included in the pricing without any additional purchase requirements."

"We are happy with the pricing that we get from Dell."

"HCL Tech has a TLA with Dell, so in terms of price point, we are very competitive. Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market."

More Dell PowerStore pricing and cost advice

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

"The product has an average cost."

"The solution's price is competitive."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

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

"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."

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."

"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."
