The ability to leverage multi-tenancy along with immutability is a huge benefit for us

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. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Seamless integrations, high availability, and offers a free version

Although I am generally satisfied with VSAN and its performance, there are some areas that could be improved to enhance its effectiveness even further. One area that could benefit from improvement is scalability. While the tool works well in its current configuration, allowing for greater ease and flexibility in adding new nodes to the cluster without complications would be very beneficial, especially in growing environments. Additionally, I would like to see additional features in the next version, such as better support for automated resource management. This could include proactive suggestions for optimizing storage and memory usage, as well as preventive alerts about the health status of the servers. A more intuitive interface or an improved dashboard for monitoring the cluster would also be helpful, as it would facilitate performance tracking and help identify potential issues before they affect services.

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 initial setup is pretty easy and simple."

"It uses the same platform for connectivity so integration is seamless."

"We have seen a reduction in the total cost of ownership by around 20%."

"The product is scalable and easy to expand."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"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."

More Pure Storage FlashBlade pros

"GPFS monitoring is the best feature."

"The profile share is a valuable feature."

"Its great servicing high availability. That is what it is used for."

"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."

"I rate this product ten out of ten."

"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."

"It is incredibly scalable and stable."

"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."

More IBM Spectrum Scale pros

"Azure AD is much more user-friendly and has a better integration with our existing infrastructure."

More StarWind Virtual SAN pros

Cons

"I have not seen ROI."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"I would like to see more monitoring capability included in the next release of this solution."

"I would like to see the licensing fees improved as well as the price per terabytes."

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"It's on the expensive side, as expected for a niche product."

"I would also like to see better support for CIFS workloads."

"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."

More Pure Storage FlashBlade cons

"The biggest problem is that it is not able to provide block storage."

"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."

"I believe there is no graphic user interface, so they should include it."

"Integration with other vendors is not available."

"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."

"The solution's pricing could be better."

"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 wish there were some graphical user interface to access the GPFS file system creation and monitoring."

More IBM Spectrum Scale cons

"Having more support plan options would be nice."

"Scalability should be further improved, especially considering the possibility that environments may grow exponentially."

"The only way I can see this product needing improvement is the consultation level of the StarWind sales and engineers."

"While using StarWind Virtual SAN so far, I have not found anything missing."

"When you will cease your contract with StarWind (for support) your product won't be updated and that is a big selling point, especially for us, as we have loads of products from StarWind."

"I would like them to invest time in reducing the complexity of the startup and shutdown procedure."

"A mobile app to sync up for overview and status would really be helpful."

"The system performs as expected, but we're always looking for performance improvements regarding the best utilization of NVMe disks."

Pricing and Cost Advice

"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."

"I feel that the price could always be lowered."

"I understand that it is competitively priced compared to other brands."

"The product is very expensive."

"Licensing fees are paid yearly."

"Our licensing is renewed annually."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"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."

More Pure Storage FlashBlade pricing and cost advice

"The solution is costly but reliable."

"The licensing is based on the number of terabytes."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"This solution is very accessible and the pro-level for support is well worth the cost."

"I think the bang for the buck is much better with StarWind Virtual SAN."

"There are two tiers of support and in my opinion, support is worth the cost."

"We are happy with the price."

"I would suggest that you download the free version, deploy in your lab, and play with it."

"Their pricing seems pretty good, and their licensing structure is pretty straightforward."

"The scalability limitation for us is its licensing. At some point in the fairly near future, we will probably have to upgrade our license so we can store eight terabytes instead of four. We are currently at four terabytes, but we're starting to knock on the door of that capacity."

"The licensing is straightforward, with free and trial versions available."

StarWind SAN & NAS

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.

IBM

StarWind Virtual SAN provides high availability and fault tolerance for virtualized environments without the need for dedicated SAN hardware.
