IT Manager at Regin Dalarna
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.

Provides seamless research data management with effortless setup
From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS. Sometimes we go with Weka or other solutions due to this need, so it should have more IO capacity when there is a demand. More performance is needed specifically in the IO area.
Amarnath Charugundla - PeerSpot reviewer
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

"It performs well and it is also very fast."
"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."
"It is very easy to use, and it is very fast."
"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."
"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."
"FlashBlade offers low latency, high throughput, and seamless scalability."
"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."
"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"I rate the stability of Amazon FSx ten out of ten."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"The shared storage capability is highly valuable."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"The integration with Prism Central makes it a lot easier to manage, so we just have a single pane of glass location that we can go to. We do not have a separate admin console or anything that we have to use."
"The migration from VMware to Nutanix Unified Storage (NUS) is less complex and less troublesome, and the replication and clustering are very good."
"The product is good, easy to upgrade, easy to use, and user-friendly."
"For somebody like me who grew up building what others call three-tier and I call traditional architecture, the valuable thing is that you can now buy it. You can have new deployments and infrastructure up and running with very little infrastructure behind it."
"The Nutanix block files are the most valuable feature."
"Nutanix Unified Storage (NUS) is very scalable."
"The solution is stable and extremely easy to calibrate."
"I find that Nutanix’s resilience is the most valuable because it is a feature that is not found in other technologies."
 

Cons

"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"The feature that we're waiting on is better integration with the cell services."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"I have not seen ROI."
"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."
"I would like to see more deduplication."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"The biggest thing for me, which is a pet peeve of mine, is the integration with the hardware platforms."
"There should be more automation. Going deeper, I would appreciate seeing out-of-the-box automation for storage provisioning and maybe some more customer-facing, web portal-type or API functionality to Jira or ServiceNow."
"Security is an area for improvement. When there are vulnerabilities, there needs to be a faster approval process. The solution needs to automatically target the vulnerabilities and not waste too much time."
"The GUI is easy to use, but it's complex to do tasks from the command line. That is one way they could simplify things for the engineers. People tend to use a graphical interface more than the command line interface. If anything goes wrong, we need to do troubleshooting from the CLI. It would be nice if there were more ways to fix issues within the GUI."
"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp."
"The analytics part of Nutanix Unified Storage is too big and should be made smaller and less resource-hungry."
"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."
"The solution's monitoring and security features could be improved."
 

Pricing and Cost Advice

"I understand that it is competitively priced compared to other brands."
"I feel that the price could always be lowered."
"The pricing for FlashBlade is between cheap and moderate."
"The price could be cheaper."
"We used a reseller for the purchase."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"The price of this solution could be made more affordable."
"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"I assume Nutanix Unified Storage (NUS) has helped reduce our total cost of ownership."
"Nutanix Unified Storage is competitively priced. There aren't any competitors that can do much better for the same price."
"My company is in Brazil, and making the payments in dollars is tough for our organization."
"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 pricing is a bit too high."
"The pricing is fair."
"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."
"Nutanix Unified Storage pricing is reasonable."
