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.

Achieving seamless cost-saving implementation with exceptional support

The best features that StarWind Virtual SAN offers include the price because comparing to other virtual SAN solutions, this one is the best, and it also has a great support team behind it. My experience with their support has been positive, as their guides regarding the integration are very useful. They have some awesome guides online that show you exactly how to configure the product, how to do the initial setup, and you can speak with them directly. They will be able to connect and verify your setup, run its parameters and see exactly what's working and what is not, and they really help you with that. StarWind Virtual SAN has positively impacted my organization and my customer through initial cost saving. They use this product in a dark site, so I'm not able to provide any additional details about this, but they were really glad about it, they're still using it, and they asked for extending the capacity for it and the support. They really want to use it and are enjoying using it.

Quotes from Members

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

Pros

"The initial setup is pretty quick."

"The most valuable features are the Metro clustering, and disaster recovery."

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

"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."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

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

"The initial setup is pretty easy and simple."

More Pure Storage FlashBlade pros

"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."

"IBM provides exceptional technical support, which I rate as the best along with Cisco."

"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."

"The biggest benefits of IBM Spectrum Virtualize are its stability, data security, and customer support."

"It lowers cost. It does so by getting more efficient use out of the technology behind it."

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

"The SVC gives excellent performance with tiered storage behind it."

"It has the ability to seamlessly move hardware in and out as we refresh technology."

More IBM Spectrum Virtualize pros

"The solution is also quite flexible. As an example, other vSAN solutions that we looked at had more stringent requirements regarding mixed HDD/SSD storage which wouldn't have worked in our environment."

"The product has improved the ability to mimic physical SAN environments to demo scenarios and troubleshoot problems."

"It includes every feature that a traditional SAN offers and so much more."

"Integration with virtualization platforms helped us to resolve many issues we were facing while using the physical storage."

"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."

"You can build cheap, reliable, replicated virtual machines clusters using simple servers with an all flash disk or SAS\SATA hybrid tiered by performance storage."

"Given the high availability of the server cluster, we were able to reduce separate physical servers onto one hyper-converged cluster - this saved in OPEX and CAPEX costs immediately, along with licensing costs of the Windows Server licenses."

"The most valuable feature is the fact that the nodes are Active/Active, and allow us to do upgrades on any node without any downtime."

More StarWind Virtual SAN pros

Cons

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

"It's on the expensive side, as expected for a niche product."

"I would also like to see better support for CIFS workloads."

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

"The solution is expensive."

"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."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"In general, the migration is complicated. Though, it is case-by-case."

"The disk reliability is not that good."

"Level 1 technical support needs improvement."

"The case logging process is efficient, but resolving software problems takes too much time."

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

"I would like to see them provide a unified platform that offers block, file, and object-based protocol access."

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

"Adding features for data deduplication is one area of improvement."

More IBM Spectrum Virtualize cons

"Some configuration options still demand service restarting."

"I would love to see more vendor selection to be available for the HCA/vSAN appliances."

"Performance when in storage-separate configuration needs to be improved."

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

"The dashboard is functional, but it could benefit from a more modern and visually appealing design."

"I would say that the documentation is mostly great, however, some features could be expanded upon a bit."

"I'd love to see more clarification for us folks who are smart enough to do some damage yet not smart enough to use CLI."

"The number of different ways you can set it up can make it a little daunting."

Pricing and Cost Advice

"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."

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

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

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

"The price could be cheaper."

"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."

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

More Pure Storage FlashBlade pricing and cost advice

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

"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."

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

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

"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."

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

More IBM Spectrum Virtualize pricing and cost advice

"The setup cost, pricing, and licensing are very straightforward. They are exactly what you expect."

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

"The Price/Performance ratio for this solution is outstanding!"

"We evaluated other options and this one was the most cost-effective."

"StarWind is a low-cost, full-featured alternative to the traditional SAN environment, and their support will guide you every step of the setup."

"The pricing is fine for the work that it does."

"The cost, including OPEX, is lower compared to other solutions."

"Cost is affordable and licensing is smooth."
