Featured Reviews

Eric Black - PeerSpot reviewer
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.
Bernd Stroehle. - PeerSpot reviewer
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.
MD.Faisal Alam - PeerSpot reviewer
Built-in compression enhances data management efficiency
I have noticed that the technical support for software issues, such as with Spectrum Protect, needs improvement. The case logging process is efficient, but resolving software problems takes too much time. This delay can hinder customers and strain vendor relationships. For hardware issues, IBM handles them efficiently, but software-related support requires enhancement. Overall improvement in support for software cases is necessary.

Quotes from Members

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

Pros

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"The initial setup is pretty quick."
"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"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."
"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 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."
"It is very easy to use, and it is very fast."
"The most valuable features are the Metro clustering, and disaster recovery."
"It is incredibly scalable and stable."
"Allows us to share files across multiple environments."
"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."
"The most valuable feature is the ability to share files across different platforms."
"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."
"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."
"The profile share is a valuable feature."
"It lowers cost. It does so by getting more efficient use out of the technology behind it."
"The most valuable feature is its reliability."
"The ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."
"It has the ability to seamlessly move hardware in and out as we refresh technology."
"We acquire companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage."
"I like all the features, but the most impressive recently has been the introduction of IBM's Flash Core Modules. They are a form of a flash drive, but they have many more features."
"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."
"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."
 

Cons

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"The solution is expensive."
"The speed could be improved."
"Pure Storage FlashBlade should improve on more cloud integration."
"I would like to see more monitoring capability included in the next release of this solution."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"They need better integration with public clouds along with a better hybrid solution."
"I want efficiency. FlashBlade doesn't have efficiency now."
"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."
"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."
"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."
"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."
"The biggest problem is that it is not able to provide block storage."
"There can be improvements in fault tolerance and making erasure coding faster."
"Maybe it needs integration with HA."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"The disk reliability is not that good."
"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"In general, the migration is complicated. Though, it is case-by-case."
"IBM could improve IBM Spectrum Virtualize by bundling Storage Scale and Storage Virtualize into a single appliance. This would provide a more appealing and cost-effective solution."
"GUI should be developed in HTML5 as opposed to Java."
"The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve."
 

Pricing and Cost Advice

"The product is very expensive."
"I understand that it is competitively priced compared to other brands."
"The price could be cheaper."
"The price is a little high."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"Our customers have seen a reduction in TCO."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"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 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."
"It has a lot of advanced functions for a reasonable price."
"This solution came as an additional cost for the TSM package we chose."
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"We would like the CPU cycle to save more on the licensing costs for us."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"I think it is a good value for the price."
"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."
