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.

Pros

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

"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 is pretty easy and simple."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"FlashBlade offers low latency, high throughput, and seamless scalability."

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

"The most valuable features of this solution are the rewrite speed and the nonstop services."

"The most valuable feature is Safe Mode."

More Pure Storage FlashBlade pros

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

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

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

"The profile share is a valuable feature."

"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."

"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."

More IBM Spectrum Scale pros

"Repair efforts have been reduced to nearly nothing."

"The option to deploy a hyper-converged system without an expensive storage switch was a benefit."

"The low cost of this solution has also made a big difference in our budget, which has been very helpful."

"StarWind is very resilient and built off of quality vendor hardware."

"The support is the most valuable feature. The support has been amazing. It's around the clock. One of our hard disks accidentally ejected without me knowing or being onsite. They called and told me about it before I had a chance to see it myself."

"I do like that I can manage StarWind with a console running on my local desktop."

"Being able to log on to the GUI to see specific data and usage statistics, executing clones, starting and stopping VMs, etc., is great."

"Their support team is extremely helpful, and they are pretty friendly and knowledgeable."

Cons

"The solution is expensive."

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

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"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."

"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."

"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."

"The feature that we're waiting on is better integration with the cell services."

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

More Pure Storage FlashBlade cons

"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."

"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."

"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."

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

"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."

"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."

More IBM Spectrum Scale cons

"I think some performance metrics would be nice to see, especially on the storage side."

"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."

"We haven't had to use the ProActive Premium Support feature much yet. But they contacted me one time because there was a glitch on one server, a networking issue... I have not seen the problem since."

"It would be amazing if there was, perhaps, a more automated process for updating the hosts themselves, although the maintenance mode works well."

"We struggle a little with capacity management with the StarWind Hyperconverged appliance."

"I'd like a better UI and some limitations on "breaking it.""

"A possible thing is perhaps a customer portal to schedule a time with support online via a calendar."

"We have to pay for support, which is high-end support. That can be expensive, at least for us."

Pricing and Cost Advice

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"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."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"Our licensing is renewed annually."

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

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

"The product is very expensive."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"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."

"The solution is costly but reliable."

"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."

"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."

"I was able to bring the price per year down by going out to a five-year plan."

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

"There is a bit of a start-up cost. Having never used HCAs before, I was reluctant to buy it. I would suggest that you jump in and do it, as I wish I hadn't wasted so much time."

"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."

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

For SMB, ROBO and Enterprises, who look to bring in quick deployment and operation simplicity to virtualization workloads and reduce related expenses, our solution is StarWind HyperConverged Appliance (HCA). It unifies commodity servers, disks and flash, hypervisor of choice, StarWind Virtual SAN, Microsoft Storage Spaces Direct or VMware Virtual SAN and associated software into a single manageable layer. The HCA supports scale-up by adding disks and flash, and scale-out by adding extra nodes.

StarWind HyperConverged Appliance consists of StarWind Virtual SAN, Microsoft Storage Spaces Direct or VMware Virtual SAN “Ready Nodes”, targeting those, who are building their virtualization infrastructure from scratch. In case there is an existing set of servers, we offer a “software only version”, which is essentially our years proven StarWind Virtual SAN. Basically, it’s the fuel powering StarWind HCA.
