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.

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies
IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

Infrastructure efficiency has improved significantly with quick server provisioning, though physical to virtual migrations need a streamlined in-house tool
From my experience with Nutanix Cloud Infrastructure (NCI), there is one area that needs improvement. When moving a critical infrastructure from a physical machine to Nutanix Cloud Infrastructure (NCI), we currently have to use a third-party tool to convert the physical machine to a VM. We have to use VMware converter to perform this conversion before moving it to Nutanix Cloud Infrastructure (NCI). I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.

Quotes from Members

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

Pros

"Speed and ease of use are the two most valuable features."
"The most valuable feature of this solution is performance."
"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 most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"It is very easy to use, and it is very fast."
"I would rate Pure Storage FlashBlade a ten out of ten."
"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"It uses the same platform for connectivity so integration is seamless."
"Allows us to share files across multiple environments."
"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."
"I rate this product ten out of ten."
"The profile share is a valuable feature."
"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."
"We are using it for monitoring all of our storage."
"Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward."
"IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM."
"Nutanix Acropolis AOS is easy to use, integrates with other hardware configurations, and is simple to manage."
"I definitely find the reduced power consumption very valuable."
"The speed of the operations and of creation of VM is fantastic."
"Nutanix Cloud Infrastructure's most valuable feature is the flexibility to move the VMs easily, keeping everything together."
"Technical support is okay."
"The solution is well integrated with other vendors."
"It has seamless expandability."
"The ease of deployment is very good."
 

Cons

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."
"I would like to see the licensing fees improved as well as the price per terabytes."
"Its configuration should be easier."
"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."
"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"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."
"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."
"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."
"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."
"Initially, stability was a concern as we encountered numerous issues and errors."
"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."
"Maybe it needs integration with HA."
"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."
"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."
"Integration with other vendors is not available."
"For the company process, the price is too high."
"Nutanix Cloud Infrastructure's LTS version needs to be more reliable."
"We would like to see it support other systems outside of the compute stack from which it was built."
"Nutanix Acropolis AOS could improve by adding some NAS features, similar to the ones that are available in the NetApp solution."
"This solution offers excellent functionality but could use a stronger interface."
"The GUI for this solution needs improvement."
"The cost of the solution is too expensive. There are other options, such as VMware, that are offered for less money. In Latin America, it seems to be overpriced for the market."
"Deployment could be more user-friendly - currently, it requires certain skills with the network and nodes."
 

Pricing and Cost Advice

"The price is a little high."
"I feel that the price could always be lowered."
"The price could be cheaper."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"Our customers have seen a reduction in TCO."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"The price of this solution could be made more affordable."
"The product is very expensive."
"The solution is costly but reliable."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"The licensing is based on the number of terabytes."
"We have a three-year license for the use of this solution."
"We renew our license on a yearly basis and have no costs in addition to the standard fee."
"The price is good but I think there is still room for improvement on the price."
"In terms of the solution's licensing, it's quite comprehensive."
"When we purchase a new physical server or a couple of physical servers into our cluster, we always purchase it with Nutanix licensing. We are receiving the license from Nutanix directly and not from the vendor. In the way we're dealing, with the licenses it is a bit costly for us but as the company is getting larger, day by day or year by year, those licensing costs become lower each time for us. We are purchasing the licenses for three years for some of our clusters and for some others for five-year licenses and the licenses are still costly. We have good discounts for the licenses, but it is still expensive."
"If they could further reduce the cost, that would be great. I would like to see the cost be less than the equivalent three-tier architecture."
"We are aware of the pricing since we renew every year, at almost $100,000 per year."
"We just have a support license for Nutanix."
