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.

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.

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

"The onboarding and integrated monitoring tools are pretty good."

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

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

"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."

"The product is scalable and easy to expand."

"The solution provides many controllers."

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

"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

"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."

"We can failover easily, because a lot of our data is replicated from family to the second replication."

"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."

"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."

"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."

"I like that it can virtualize more than three hundred storage providers."

"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."

"The ease of management, the simplicity of the CLI, the speed of that interface, and the well-architected design of the product in general are valuable features."

More IBM Spectrum Virtualize pros

"Using our own choice of HW allowed us to price our service to answer our customers' needs."

"When we need additional storage but want to keep the size of the SANs manageable, the StarWind Virtual SAN has allowed me to do everything needed."

"Virtual SAN runs on iSCSI, which is free and easy to configure. It's easy to manage from StarWind's GUI console, and it only required a few extra switch ports."

"The StarWind Virtual SAN management console is intuitive and easy to use."

"The software is easy to setup and manage, and the support is excellent."

"Integration with Microsoft clustering has been perfect, allowing us to leverage our investment in MS server licensing to the fullest."

"We have experienced multiple hardware failures at one site and the fault-tolerant volume worked exactly as expected with zero downtime."

"Starwind support is excellent. They are very fast and have very good knowledge of Starwind and Hyper-V Cluster software."

Cons

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"The speed could be improved."

"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 have not seen ROI."

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

"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."

"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."

"There could be improvements in public cloud integration."

More Pure Storage FlashBlade cons

"I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."

"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."

"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."

"The Storwize port is not so stable."

"t is limited in terms of a single system to eight nodes or four, what they call IO groups."

"For improvement considerations, I would probably say multiple sites."

"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."

"Anything which improves performance and the ability of our systems would be a nice."

More IBM Spectrum Virtualize cons

"The software could benefit from more tooling to help with initial deployment."

"Maybe in the future, the replication will be supported in more cloud providers."

"For the StarWind VSA vSphere solution, I would like to see a simpler and automated virtual machine installation process in terms of network settings."

"This solution should be more self-sufficient, running without creating domains or failover clusters."

"There is no Italian-language version of the software available."

"The software monitoring should be web-based to be reachable from any VLAN workstation."

"The Command Center, a free guest VM for management and monitoring, leaves something to be desired. It could have more accurate real-time information and better reporting visuals, which seem to be an afterthought."

"Although minor, some of the documentation could be rewritten to be clearer."

More StarWind Virtual SAN cons

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."

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

"We used a reseller for the purchase."

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

"The price is a little high."

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

"The product is very expensive."

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

More Pure Storage FlashBlade pricing and cost advice

"We would like the CPU cycle to save more on the licensing costs for us."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"This solution came as an additional cost for the TSM package we chose."

"Do a proof of concept, if you are not comfortable jumping in, but do it."

"It has a lot of advanced functions for a reasonable 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."

"I think it is a good value for the price."

"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."

More IBM Spectrum Virtualize pricing and cost advice

"I think the cost of this solution is quite fair."

"This is the best priced solution for an SMB."

"Once you buy the license, you are free to build your own hardware solution based on your needs."
