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.

System Engineer at Tata Consultancy

Unified management and cost-effectiveness lead to positive experiences and future savings

Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

"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."

"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."

"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."

"IBM FlashSystem is an excellent product."

More IBM FlashSystem 9100 NVMe pros

"DR and the replication power are valuable."

"The most valuable feature of Nutanix Unified Storage is the ease of setting up file shares. As a global company with data centers around the world, our files clusters are accessible globally. Managing and setting up shares for our over 12,000 employees is straightforward."

"Nutanix Unified Storage is very stable."

"The availability of the environment is incredible, and with Prism Central, you're able to diagnose and go over issues quickly."

"It is very scalable."

"I would rate Nutanix Unified Storage a ten out of ten."

"The life cycle managers of the PCMs are very impressive, and I like them. They make our lives easy when managing patches and security updates when they come in. A life cycle manager helps to consolidate different vendors."

"The solution's most valuable feature is the Prism Central centralized management console."

More Nutanix Unified Storage (NUS) pros

Cons

"The solution should improve its logon requirements."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"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."

"The tool's portfolio is minimal. It is expensive."

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

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

"Its price is a little high right now. Otherwise, I would have given it a ten."

"In terms of what needs improvement, the dashboard and management could be simplified."

More Everpure FlashArray X NVMe cons

"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."

"The solution's compression feature could be better."

"Other vendors have included a block and file system. IBM doesn't include a file system."

"The support could be better."

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

"The pricing should be more competitive."

"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."

"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."

More IBM FlashSystem 9100 NVMe cons

"Managing other storage infrastructure on Nutanix Files Storage is an area for improvement. In particular, I want to add other forms of storage from different vendors not currently in Nutanix Files Storage, to the file server, for better management."

"What's missing in Nutanix Files Storage is the support for multiple intranets or VLANs on the same file from different networks and network devices."

"There is potential to push this product more since it's not common in the market. They could increase their marketing efforts."

"The solution should keep adding new features to be competitive in the market."

"We couldn't access Nutanix Unified Storage (NUS) from Prism Central due to bugs. The bugs that Nutanix fixed in newer versions prevented us from accessing Nutanix Unified Storage (NUS) from Prism Central."

"I acknowledge that the price of the product can be too high, and it would be beneficial if pricing were more flexible for end users."

"Pricing can always be better."

"The graphical user interface could provide more detail. It would be nice if we could click on the service and get some expanded definitions of them. When hiring new people, it's difficult to teach them how everything works, but if they can access everything, they can teach themselves."

Pricing and Cost Advice

"The licensing is on a yearly basis."

"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."

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

"We pay approximately $50,000 USD per year in licensing fees."

"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."

"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."

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

More Everpure FlashArray X NVMe pricing and cost advice

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

"The tool's pricing is competitive."

"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."

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

"The product has an average cost."

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

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

More IBM FlashSystem 9100 NVMe pricing and cost advice

"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."

"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."

"The pricing is a bit too high."

"Nutanix Unified Storage isn't expensive."

"The licensing model the tool has is cheaper than an HCI storage solution."

"If we compare the cost of Nutanix Objects Storage to other solutions such as VMware licenses, our current choice is Nutanix Objects Storage. This solution is more cost-effective. However, adding VMware to Nutanix would not be a cost-efficient decision, which is why we do not use it anymore."

"The price of the license is expensive when comparing it to traditional storage."

"The pricing is fair."
