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.

Flexible and scalable file system for growing storage needs
Gluster FS is used for various purposes, including virtualization, collaboration, and data center environments. It is also applied in personal environments. Some specific use cases mentioned include scaling a three-terabyte file system into a 12-terabyte file system with minimal downtime Gluster…

Quotes from Members

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

Pros

"FlashBlade offers low latency, high throughput, and seamless scalability."
"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."
"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."
"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."
"It uses the same platform for connectivity so integration is seamless."
"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 product is scalable and easy to expand."
"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."
"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."
"It is incredibly scalable and stable."
"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."
"It is a scalable solution."
"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."
"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."
"The profile share is a valuable feature."
"Notable features of Gluster FS include flexibility, scalability, stability, and ease of use."
"The price tag is good compared to the amount of data and high availability provided."
"The technical support team is excellent."
"It's very easy to upgrade storage."
 

Cons

"I would like to see more VM-Aware features in the next release of this solution."
"I would also like to see better support for CIFS workloads."
"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."
"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."
"The feature that we're waiting on is better integration with the cell services."
"Its configuration should be easier."
"Its configuration should be easier."
"The features provided for SMB customers are limited."
"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."
"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."
"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."
"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."
"I believe there is no graphic user interface, so they should include it."
"The solution's pricing could be better."
"There can be improvements in fault tolerance and making erasure coding faster."
"There is a feature in Red Hat’s commercial version that could be beneficial if integrated into the open-source version."
"The user interface could be simplified."
"The system should be more intuitive and easier to manage."
"The performance of the solution must be improved."
 

Pricing and Cost Advice

"The price of this solution could be made more affordable."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"The pricing for FlashBlade is between cheap and moderate."
"We used a reseller for the purchase."
"The product is very expensive."
"I understand that it is competitively priced compared to other brands."
"The price could be cheaper."
"Licensing fees are paid yearly."
"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
"The solution is costly but reliable."
"The licensing is based on the number of terabytes."
"If you need cheap storage, but still need high availability, it's a good product to look at."
