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.

Reliable flash storage has delivered strong data reduction and secured sensitive information

There is still some room for improvement when it comes to scalability, mainly in the interoperability and integration aspects. Every storage vendor has certain limitations, and this is not limited to NetApp; it applies to everyone in the industry. I do not see any other significant areas for improvement with NetApp AFF C-Series at this time. NetApp is working on their roadmap, which is solid, and they are developing certain features that are yet to be released.

Quotes from Members

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

Pros

"It has good, reliable, fast storage."

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

"What we've seen on the Xs, and the Pures in general, is that we can scale way beyond what we need to without any degradation in performance."

"The initial setup was extremely simple and straightforward."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"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 solution uses newer technology for deduplication and compression."

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

More Everpure FlashArray X NVMe pros

"They have a virtualization feature and, even if you do not want to buy that feature, you can have it as a trial for two to three months. If you have another brand of storage from another company, you can use this tool to transfer all your data from the old system to the new Storwize system, which really shortens the migration time."

"If you are looking for a great flash solution that can be virtualized or utilized as a building block for a scalable flash solution, or if you're looking for flash for a very specific workload, then you may want to consider a FlashSystem 900."

"It is simple to make an update."

"The pricing is reasonable."

"The storage system is one of the best in the world."

"This solution is very stable."

"The stability of the product is very valuable."

"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."

More IBM FlashSystem pros

"NetApp AFF C-Series is a good product for entry-level flash storage, the system is competitive in terms of pricing, and the value proposition is strong."

"NetApp offers a cost-effective solution with very robust hardware."

Cons

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

"They could add more support for file storage and different types of storage."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"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."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"The only area I wish to see improve, I believe is coming, is in the FlashBlade product."

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

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

More Everpure FlashArray X NVMe cons

"We think that IBM has to continue to invest in additional data reduction capabilities which are on their roadmap."

"I would like to see bigger modules."

"We had issues when attempting to do a flash, we hope to resolve it soon."

"There is a need for a little bit more of a drill down in the GUI part."

"Flash Manager needs to be included."

"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."

"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."

"The several major crashes resulted in the entire weekends being lost in rebuilding the array and then for restoring the data."

More IBM FlashSystem cons

"We faced one bug that impacted our NetApp last month, and it took some time to identify the underlying issue."

Pricing and Cost Advice

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

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

"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."

"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."

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for 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."

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

More Everpure FlashArray X NVMe pricing and cost advice

"The cost of the IBM FlashSystem is lower than the HPE solution."

"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."

"I find the pricing of the solution to be very reasonable."

"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."

"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."

"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
