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.

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.

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"Technical support has been helpful and responsive."
"The most valuable features of this solution are its ease of use and performance."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"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."
"Overall stability is very good. It is a very stable solution."
"The solution is very straightforward to set up."
"The latency is good."
"The inclusion of it in the Nutanix Objects Storage platform simplifies my process as I am no longer required to acquire a separate platform. Instead, I can simply purchase additional licenses as needed. All management can be performed from a single unified interface, making it a convenient and streamlined experience."
"It is a highly scalable solution."
"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 reliability and availability are the most valuable features. Reliability is important because it can run my workloads. I need to be able to take advantage of the VMs that are executing on the storage. It has to be reliable. It's also important to have the storage available for scaling VMs on demand."
"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, ease of use, and technical support are the most valuable features of Nutanix Unified Storage."
"Nutanix Unified Storage is easy to use. New employees are able to come up to speed fairly quickly with regard to the day-to-day administration processes."
"The customer service executives of all Nutanix products are active and responsive."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"The tool's pricing is higher than competitors."
"In terms of what needs improvement, the dashboard and management could be simplified."
"They could add more support for file storage and different types of storage."
"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."
"There is room for improvement in the pricing of the product."
"Maybe the price can be reduced since the solution is very expensive."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"For me, personally, it's a little bit slow because there's so much stuff in the underlying layers that even after talking with Nutanix support, I couldn't really grasp it."
"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."
"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."
"Requires higher upfront investment"
"Nutanix Unified Storage (NUS) needs improvement in compatibility with Windows solutions."
"From the speed perspective of Nutanix Unified Storage (NUS), it could enhance some features to make it the best storage solution in the market."
"For future updates, I think Nutanix Unified Storage (NUS) should look at features similar to what ONTAP of NetApp is doing, such as tiering to the public cloud."
"It would be beneficial if there were a migration tool for the new way of syncing data for data protection."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
 

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."
"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'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."
"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."
"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."
"Given its price, Pure is not the first option."
"We pay approximately $50,000 USD per year in licensing fees."
"Nutanix Unified Storage was cheaper than other solutions we evaluated."
"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."
"The product is neither cheap nor expensive, making it a solution offering a price range that is in the middle."
"Nutanix Unified Storage isn't expensive."
"It's competitive and attractive for moving things to it and then prioritizing those newly freed up resources for something else."
"The solution is highly-priced."
"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."
"Nutanix is priced a bit higher than some of its competitors. A lot of Chinese companies like Huawei are entering the Saudi Arabian market trying to provide similar solutions for a lower price. It offers a good value, especially the support. Nutanix has a highly competent team. The after-sales support is excellent."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
