Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."
"The most valuable features of this solution are the rewrite speed and the nonstop services."
"It uses the same platform for connectivity so integration is seamless."
"The most valuable feature of this solution is performance."
"The product is scalable and easy to expand."
"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"We migrated over to Nutanix and saw an immediate improvement in the performance."
"One of the main features of Nutanix Unified Storage (NUS) that I find most valuable is the flexibility and scalability of it, as well as the ability to perform replication for our Disaster Recovery environment."
"The solution's most valuable feature is the Prism Central centralized management console."
"The simplicity of management is valuable because, in more traditional environments, the platform updates are much more complex."
"The reliability and stability of Nutanix Unified Storage (NUS) is good, and the disaster recovery component is something impressive for this product."
"I would rate Nutanix Unified Storage (NUS) a ten out of ten."
"The most valuable feature is the easy interface."
"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."
"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

"I would like to see better integration."
"Pure Storage FlashBlade should improve on more cloud integration."
"I would also like to see better support for CIFS workloads."
"It's on the expensive side, as expected for a niche product."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"I have not seen ROI."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"Its configuration should be easier."
"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."
"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."
"There is no tagging concept in Nutanix Unified Storage where you can tag the servers."
"There should be more automation."
"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."
"Nutanix should improve the one-click upgrade. There are a lot of dependencies on third-party licenses and HP hardware we use internally. The one-click upgrade fails sometimes."
"I really want some AI or even basic AI to be included in the Nutanix Unified Storage (NUS) license."
"While the stability of Nutanix Unified Storage (NUS) is good, the need for manual intervention can be a drawback."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Licensing fees are paid yearly."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"The price could be cheaper."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
