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.

Deliver improved performance in data processing and foster extensive AI initiatives

I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system. It achieved the best results when integrated with IBM hardware. Even though it is complex, it provided significant performance advantages in large-scale data management. Its fault tolerance mechanisms and integration capabilities make it popular for extensive AI initiatives and data processing tasks for organizations like Daimler Benz and Bosch.

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

"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."

"We can capacity plan at a greater level than we used to."

"Using this solution has made our backups more reliable."

"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 most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

More Pure Storage FlashBlade pros

"It is incredibly scalable and stable."

"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."

"We are using it for monitoring all of our storage."

"Allows us to share files across multiple environments."

"Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward."

"We can have multiple systems within the same file system."

"It is a scalable solution."

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

More IBM Spectrum Scale pros

"As the client had acquired another company some distance away, they were concerned about having a single SAN in one location or the other. StarWind vSAN allowed us to keep a copy of the data local to each site without asking the client to pay for two SANs in addition to the two new servers they needed."

"I save both physical and virtual space."

"It is easy to use and can monitor system synchronization and check Storage status. StarWind Virtual SAN (VSAN) combines flash and disks of the cluster and forms a virtual shared storage “pool” accessible by all hosts. StarWind cuts down virtualization cost and complexity by eliminating the need for a physical shared storage (SAN). -StarWind offers the Enterprise-level high availability (HA), deployed and easily configured . we get technical support from star wind team when implementation software and after setup if we face any issue."

"I've been really impressed with it so far. I think it's pretty great, actually. It does exactly what we need it to do, and it does it well, so I would recommend it. Plus, the support has been very good."

"The available GUI is excellent for monitoring and operating the system in an easy and direct way."

"The feature I have found most valuable in VSAN is its high availability capability."

"We are able to execute maintenance on one server while the other is still running."

"With an uptime of 384 days, StarWind has improved overall server reliability."

Cons

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"I want efficiency. FlashBlade doesn't have efficiency now."

"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."

"I would like to see more deduplication."

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

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

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

More Pure Storage FlashBlade cons

"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."

"Maybe it needs integration with HA."

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

"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."

"The solution's pricing could be better."

"There can be improvements in fault tolerance and making erasure coding faster."

"Integration with other vendors is not available."

"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."

More IBM Spectrum Scale cons

"For improvement, I would like to see how the software determines which networks to use for which purpose. It seems like the naming terminology changes a bit from here to there."

"With data verification, I would like to know how does the solution perform validation of data being synced between two VSANs."

"More comprehensive reporting and educational resources for error resolution would enhance the user experience."

"Diagnostics information or alerts on the state of systems could also be implemented to give more visibility."

"This product could be improved with the inclusion of new health check procedures."

"StarWind doesn't really have any performance reporting, especially compared with other vSAN products we've used."

"Besides not being able to use any filesystem, I do not have any additional cons."

"When StarWind Virtual SAN for vSphere nodes go offline unexpectedly, the nodes have to re-sync disks fully which takes a long time. We had a power failure and when both nodes came online, VMware vSphere didn't see StarWind disks before I manually re-scanned them form ESXi administration console even though it should happen automatically"

"The product is very expensive."

"Licensing fees are paid yearly."

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

"I rate the tool's pricing a seven to eight out of ten."

"The price of this solution could be made more affordable."

More Pure Storage FlashBlade pricing and cost advice

"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."

"This is a good, economical solution compared to data storage systems."

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

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

"This solution has a great price for the functionality."

"The StarWind VSAN business model is very cost-effective."

"Licensing is based on nodes rather than TBs, which means that the users are free to increase storage capacity without putting thought into licensing."

"The cost takes into account the number of nodes, so the size of the storage is not important."

"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."

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
