Jaehoon Oh - PeerSpot reviewer
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.

Transition from costly infrastructure lowers expenses and improves hardware performance
NetApp offers a cost-effective solution with very robust hardware. Frequent improvements are shared through bulletins so we can enhance hardware performance by upgrading the ONTAP version. Firmware upgrades are also widely distributed. Weekly calls with NetApp ensure we're staying on top of any potential issues. The transition from SAN-based to NetApp storage eliminated SAN switch costs and reduced CommVault dependency, lowering license costs significantly.
Amarnath Charugundla - PeerSpot reviewer
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

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Everything, especially the VMs inside, is pretty fast."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The latency is good."
"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."
"NetApp offers a cost-effective solution with very robust hardware."
"Whenever we have some necessity in terms of capacity and expansion of infrastructure, it's like a Lego system where they can just place in some more nodes and our needs are met."
"Nutanix Unified Storage does a very good job of unifying our organization's block, file, and object storage. It puts it all in one place. From one platform, we can deploy S3-type buckets. We can provide iSCSI-level block storage if we need to. It does a great job with home folders and departmental shares, which is what we mostly use Nutanix Unified Storage for."
"The scalability, data redundancy, and security are valuable."
"Offers high performance, full control, and strong security for mission-critical workloads."
"Some of the features that we use include replication and snapshot capabilities, especially from remote locations to our data centers. The main benefit our company sees from using Nutanix Unified Storage is simplification. In the past, we used three-tier solutions with a lot of complexity and operational overhead. Now, we want to focus on the layers above. I want to have storage available, but I don't want to have to think about it. I want it to work without any issues."
"The capacity is very good. They use fewer nodes than before. Each node is isolated with the CPU with the performance. It is a cluster node but works separately, so the performance will be tripled."
"The product's benefits stem from the ease of use and management it offers to its users."
"The solution is simple and robust."
 

Cons

"Adding some functions to the product would be beneficial."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The software layer has to improve."
"I would like to see replication and DR features in the next release of this solution."
"It is on the expensive side."
"We faced one bug that impacted our NetApp last month, and it took some time to identify the underlying issue."
"We faced one bug that impacted our NetApp last month, and it took some time to identify the underlying issue."
"For P1 and P2 alerts in the Nutanix Unified Storage (NUS) file share system, including SMB, NFS, objects, or blocks, we must maintain vigilant monitoring. This is crucial because system downtime can disturb the entire ecosystem and impact all applications."
"Areas for improvement in Nutanix Unified Storage (NUS) include more redundancy to ensure no data loss, and balancing the workloads is very important to maintain managed workloads throughout the year."
"The dashboard can have more details and be more useful."
"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."
"Nutanix Unified Storage (NUS) can be improved in the area of big data workloads, as we still need to improve performance there."
"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."
"The biggest improvement would be to make it more cost-effective from a storage node and storage perspective, so that the solution isn't such a question when it comes to cost-prohibitiveness versus potentially other vendors."
"Pricing can always be better."
 

Pricing and Cost Advice

"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."
"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"With VMware, we pay $300,000 annually."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"Our licensing fees are $500,000+ USD."
"We pay approximately $50,000 USD per year in licensing fees."

"Nutanix Unified Storage pricing is reasonable."
"It is very good. It is much more competitive than a dedicated storage platform."
"The solution is highly-priced."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
