Chief Technology Officer at Lambda256

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.

Managing Director at GCET

Offers flexibility and top-notch technology

You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Cons

"It is on the expensive side."

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

"There is room for improvement in the pricing of the product."

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

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

"The tool's pricing is higher than competitors."

"The software layer has to improve."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

More Pure FlashArray X NVMe cons

"The pricing needs to be more competitive."

"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."

"GUI interface should be enhanced more as there is some issues in copy services."

"There could be some extra features added."

"The storage capacity of this solution could be improved."

"The solution is not easy to use and could improve."

"The array level RAID does not seem available."

"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."

More IBM FlashSystem cons

"As far as the manageability, being able to port between the two and have to do less training in-house from a customer point of view, that would be the part to improve."

"A little more manageability, a simpler management interface. It's not necessarily that it's way overly complex. It's just that it's not as easy as the FAS series."

"It was difficult to implement and lacks some additional features that would be useful, but as a solution fits a particular need for our organization."

"I’d like to see bigger, faster, better hardware, of course. I think that is the way the hardware is trending anyway; bigger, faster CPU, better software, fewer bugs, all that stuff. T"

"We need a center related to NetApp in Egypt so that we can deal with them directly."

"This solution has limited storage."

"There could be an improvement when it comes to SLA support, it could be faster."

"The support of the product is an area with certain shortcomings where improvements are required."

Pricing and Cost Advice

"The licensing is on a yearly basis."

"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 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."

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

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

"The product is expensive."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"Our customers would like IMB FlashSystem to be less expensive."

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

"This is an expensive product and if the price were reduced it would be better."

"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."

"This solution is expensive compared to other solutions."

"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."

"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."

More IBM FlashSystem pricing and cost advice

"This solution is not available to many users because the cost is very expensive."

"NetApp EF-Series All Flash Arrays is an expensive product."

"he price point that we're getting is very competitive in the market. Since we are buying in such a large quantity, they gave us a huge discount."

"Adding more capacity will increase the cost."

"The pricing of this solution is competitive with other vendors here in Egypt."

"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."

"Most of my customers pay for the license on a yearly basis. It can be expensive depending on the capacity number."

"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."
