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.

Proactive support with improved speed and resilience

There was a long delay with shipping, which we weren't expecting, but we were kept updated throughout. It wasn't made clear to us that we needed to provide our own SFP modules to connect to our infrastructure, so that could have been a bit clearer. It would be amazing if there was, perhaps, a more automated process for updating the hosts themselves, although the maintenance mode works well. Our StarWind command center doesn't seem to have all the options available currently, which support is investigating for us.

Quotes from Members

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

Pros

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

"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."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

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

"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."

"The solution provides many controllers."

"The main feature I have found to be product replication."

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

More Pure Storage FlashBlade pros

"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."

"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."

"Allows us to share files across multiple environments."

"The most valuable feature is the ability to share files across different platforms."

"It is incredibly scalable and stable."

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

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

More IBM Spectrum Scale pros

"The most valuable features of the solution are the redundancy and its cost. I used to have a SAN, a Dell EMC EqualLogic. Unfortunately, it was they call an "inverted pyramid of doom." It was two or three hosts, two switches, and one storage array at the very bottom. But the SAN, the storage array at the very bottom, is a single point of failure..."

"High-availability is what I bought it for."

"The software is great. It's very easy to understand. I've not delved into any of the command-line stuff, but there's no real need to script it. Since it went in, pretty much the only thing that I have needed to do is increase device image sizes and that process is very straightforward."

"We have the ProActive Premium Support and it has reduced our monitoring efforts. It has been very useful. They have been able to detect things such as when there's an issue with the cluster or they're getting some kind of weird reading that I have no idea about. They're really quick to let me know about it and even set up a schedule to address it. I've been very happy with their level of support on that."

"This solution came preconfigured. All we needed to do was plug it in and move our VMs."

"With StarWind's Proactive monitoring we can go about our day helping our customers and not have to worry about our cluster's health."

"It is the perfect solution for hyper-convergence at a fair price. Our customers have Hyper-V and VMware environments, with Windows servers and Linux."

"It is a safe, fast, and cost-effective storage system that improved our systems to have zero downtime."

More StarWind HyperConverged Appliance pros

Cons

"The solution is expensive."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"I would like to see more VM-Aware features in the next release of this solution."

"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."

"The documentational aspect of FlashBlade needs improvement."

"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."

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

"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

"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."

"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."

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

"Integration with other vendors is not available."

"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."

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

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

More IBM Spectrum Scale cons

"One area for improvement of the solution is that I had to get Windows, which I really didn't want because of the extra maintenance or overhead, as well as viruses, etc. It's going to take time for them to get their Linux to that point. They already have Linux but it's not as mature and they don't really support it on HCAs. They have it for individuals who want to use it on their servers, but not on HCAs."

"The only area that surprised me had to do with the fact that each host runs a StarWind virtual machine used to maintain the health of the vSAN, which individually uses 24GB of memory per host. You should keep this in mind when determining the resources you will need when selecting hardware and components for your specific setup. If I knew that, I would have chosen to add more memory per host to make up for the use."

"In the future, it would be nice to be able to migrate from the Windows vSAN to the Linux vSAN without having to do a full restore from backups."

"The response time is usually several hours after the issue occurred."

"The only issues are when Hyper V itself has limitations and I'd love to see support or enhancement in the area of direct-attached GPU cards."

"The only critique I might have is that the support is overseas in Eastern Europe and, on occasion, there has been a language issue. But in general, they're as good as can be..."

"There is room for improvement in the setup and installation phase. We had massive problems connecting the StarWind appliances to our network infrastructure. That wasn't necessarily a StarWind problem. I don't know if their business partner in the UK wasn't used to having to deal with the supply of the cabling infrastructure, but that's where the problems started."

"We need to be very cautious in following every step when updating the physical host. We must move over each VM and drain roles from the servers to ensure everything goes smoothly without interruptions. If this were a more automated process, this would be less taxing each time an upgrade is needed."

Pricing and Cost Advice

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

"The pricing for FlashBlade is between cheap and moderate."

"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."

"We used a reseller for the purchase."

"Our licensing is renewed annually."

"The price is a little high."

"Our customers have seen a reduction in TCO."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

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

"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."

"We didn't have any issue with pricing or any of the sales process."

"Our entire package was around $35,000 for everything, including three years of support."

"Its cost was reasonable."

"When I researched they came the most cost-effective."

"The Nutanix piece was about $45,000, getting close to $50,000 with all the licensing involved, whereas the StarWind was less than half of that, after Microsoft licensing and such."

"The HCA price is all-inclusive (setup, hardware, support, warranty), except for your standard Microsoft Server licensing."

"We looked at Nutanix and found it did almost the same thing but for more money. In fact, StarWind was nearly one-third of the price; it cost us £36,000. That includes five years of monitoring... The Nutanix was near enough £110,000 for relatively the same amount of performance and storage."

"The other solutions we were looking at were priced much higher than this and they didn't necessarily have full redundancy... Nutanix and VxRail were in the final running... but it came down to our price point."

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
