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.

Resilience has supported proactive management and secured audit readiness across multiple sites

The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

Quotes from Members

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

Pros

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

"Using this solution has benefitted us operationally by making us more efficient."

"The solution uses newer technology for deduplication and compression."

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

"The solution is very straightforward to set up."

"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."

"It has drastically improved the performance of our high-end Oracle databases and allows us the ability to replication to a DR location with ease."

"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."

More Everpure FlashArray X NVMe pros

"The solution saves customers time and money because it handles migrations quickly and does not require additional IT resources or staff."

"The great thing was the guarantee that came with it of the four-to-one deduplication ratio, which really helped with the pricing as well as the anytime upgrades, so from a TCO standpoint we were really able to see some benefits."

"Dell EMC PowerStore is scalable."

"It's really good, price-wise. It's cost-effective."

"The rack space I'm saving alone is an ROI because I'm able to then use those racks for more servers."

"The user interface is really simple to get behind and makes it really easy to expand and utilize the tools."

"The administration tools take advantage of machine learning and make recommendations to the admins, and that makes the administration easier."

"I rate Dell PowerStore a perfect 10 out of 10."

More Dell PowerStore pros

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

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

"The most valuable feature is the speed."

"There are many valuable features of IBM FlashSystem 9100 NVMele I have found to meet my needs. Specifically, the maintenance cycle is a standout feature of this solution. The main component of the IBM FlashSystem 9100 NVMe is the maintenance of the batteries, which have a predetermined and reliable four-year life cycle. This is in stark contrast to other solutions that may use spinning disks, which can fail unexpectedly, causing unwanted downtime and maintenance. Having a predictable maintenance cycle is a significant advantage and has made this solution a preferred choice for me."

"You get value for money, because the product is good in terms of control failure."

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

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

"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."

More IBM FlashSystem 9100 NVMe pros

Cons

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"We need better data deduplication."

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

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"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."

"In the future, I would like to see integration with enterprise backup systems."

"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."

"Pure is not flexible on your datapak expansions. You're locked into a certain amount of storage."

More Everpure FlashArray X NVMe cons

"The cost of technical support is high."

"It would be helpful for us to have support for the S3 protocol because our main competitor has the S3 protocol in their system."

"PowerStore's management console could be improved."

"Could use some additional automation."

"Reporting is an area that could be improved. It's very simplistic sometimes, and some of the very technical guys on my team want to see more of the details and be able to massage the report a little bit better."

"I have experienced some issues, downtime, and outages with Dell PowerStore, as we have had quite a few issues related to storage and resilience."

"The data resiliency and cybersecurity features of Dell PowerStore are just normal and would be considered medium; we need additional components such as cybersecurity vault for increased resilience."

"Products that are not native sometimes cause migration issues."

More Dell PowerStore cons

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

"The storage system itself should have built-in capabilities for different ransomware attacks."

"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."

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

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

"Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex."

"There is a tool provided by IBM for repairing batteries which can only be utilized by those who have an IBM technical advisor under service contract. However, for individuals who do not have such a contract, the tool can be difficult to use and requires a zip file copy. I believe that it would be greatly beneficial if the tool were made more user-friendly and accessible for all individuals who need to repair batteries."

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

Pricing and Cost Advice

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

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

"The licensing is on a yearly basis."

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

"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 support cost per array is about $20,000 a year for 24/7 support."

"The product is expensive."

"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."

More Everpure FlashArray X NVMe pricing and cost advice

"The solution is expensive."

"Pricing depends on the model and negotiation. Sometimes we manage to get good discounts, sometimes not."

"There are no separate licenses required as all the basic licenses are included in the bundle."

"Dell PowerStore is not a cheap solution."

"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."

"Dell PowerStore is affordable and the license is just a face license which is great."

"The pricing rates at seven out of ten as it is considered overpriced. Entry-level models are reasonably priced, starting around $30,000 for a base model with 6 drives. However, upgrades become costly - adding 6 additional drives can cost another $30,000."

"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

"The product has an average cost."

"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."

"The solution is priced well."

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

"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."

"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 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."

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