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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Amarnath Charugundla

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.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"The high availability of the product is the most valuable feature."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

"It has benefited my organization because it has reduced time to insights."

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

"On a scale of one to ten, I rate Pure FlashArray as ten."

"It has good, reliable, fast storage."

"Technical support has been helpful and responsive."

More Pure FlashArray X NVMe pros

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"High performance and ease-of-management are the most valuable features."

"The initial setup is straightforward."

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"It performed great originally, and when it performed great, it was awesome."

"We use IntelliFlash products for larger environments, like Qatar Airways."

More DDN IntelliFlash pros

"In the beginning, when they sold us Nutanix Unified Storage (NUS), they told us the performance would be 30%. Then we came to them and said, 'You are a liar. It's not 30%, it's 800% increase.'"

"The aspect of the product that I like the most is its simplicity."

"Nutanix Objects is reliable."

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

"The biggest advantage we find with Nutanix Unified Storage (NUS) is the performance, due to it being hyper-converged and using all-flash nodes. The storage is very responsive, and it's significantly easier to manage from the Nutanix Files platform that comes along with NUS Pro."

"It's a centralized place for management. With all our virtual machines and Kubernetes in there, it's a single place to manage all of our resources, instead of having to jump around to different places."

"The product's initial setup phase was simple."

"I find that Nutanix’s resilience is the most valuable because it is a feature that is not found in other technologies."

More Nutanix Unified Storage (NUS) pros

Cons

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

"I would like to see replication and DR features in the next release of this solution."

"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."

"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."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

More Pure FlashArray X NVMe cons

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"Snapshots are not as easy to access as on a NetApp device."

"It's somewhat scalable, but maybe not so much as some of the competition."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"In future releases, I look forward to more AI features."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

More DDN IntelliFlash cons

"The dashboard can have more details and be more useful."

"The solution needs to be more open to integration with other vendors. Sometimes, we struggle with the support process. Our skilled engineers must explain our problems to everyone, even though we've already done preliminary investigations. The support team follows standard procedures, which can be painful. We're not a small customer, especially in the life sciences sector, so we'd appreciate more specialized support. I've heard Nutanix Unified Storage has teams dedicated to life sciences and healthcare; we should be part of that."

"According to the keynotes announced by Nutanix the previous day or this morning, the data storage for Kubernetes requires improvement as it has a few shortcomings in the area of operations."

"The product needs to work a bit more on its ransomware detection capabilities."

"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."

"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."

"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."

"The CVM consumes more memory and CPU, as it will be allocated a minimum of 32 GB. For a large data store, they are unnecessarily consuming extra resources through the built-in CVM."

More Nutanix Unified Storage (NUS) cons

Pricing and Cost Advice

"The product is expensive."

"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 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 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."

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

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

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"I think we pay around 100 grand per year for three arrays or four arrays."

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"Nutanix's pricing is definitely much better when compared to other storage providers. That was one of the main reasons we switched to this platform."

"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."

"The product has an annual licensing fee."

"The solution is highly-priced."

"While the price may not be the most affordable, I believe it offers good value for the benefits it provides."

"Nutanix is very competitive."

"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."

"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."
