Solutions Architect at Recovery Point Systems

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.

Enables efficient multi-environment cluster deployment and resource management with versatile features

While VMware vSAN is quite comprehensive, if we are running multiple infrastructures, applications, databases, and other elements, having a diagnostic tool to identify the actual problem area, whether application-side or infrastructure-side, would be beneficial. A proper monitoring tool that encompasses both applications and infrastructure would help in quickly resolving issues.

Quotes from Members

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

Pros

"It performs well and it is also very fast."

"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 product is scalable and easy to expand."

"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 most valuable feature is Safe Mode."

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

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

"The initial setup is pretty quick."

More Pure Storage FlashBlade pros

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

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

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

"The most valuable feature is its reliability."

"The scalability is very good. It can handle anywhere from very small to large enterprise class."

"The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."

"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."

"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."

More IBM Spectrum Virtualize pros

"The deduplication and compression are excellent."

"The most valuable feature for our customers is vMotion. It allows them to shut down virtual machines and migrate them to others servers."

More VMware vSAN pros

Cons

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"They need better integration with public clouds along with a better hybrid solution."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"I would like to see more deduplication."

"Pure Storage FlashBlade should improve on more cloud integration."

"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."

"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."

More Pure Storage FlashBlade cons

"GUI should be developed in HTML5 as opposed to Java."

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

"The disk reliability is not that good."

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

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

"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."

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

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

More IBM Spectrum Virtualize cons

"It needs to be vanilla. There shouldn't be any custom drivers, any custom anything. It should just be, "Hey, you know what? These drivers are going to work for this version, the next version, and the following version after that." That's the difficulty in this. It takes too much upkeep... The main issue is drivers. Every time we move to a new vSAN version, we're having problems finding the correct drivers for the vendor."

"Currently, one of the available features is shareable VMBKs. You can create the VMBK disc and you can make them shareable between the ends. But as soon as you start using this feature, you lose the ability to create snapshots."

"They can improve the manageability of the solution to make it more simple. It is not that complicated, but it will be good if they can make it more simple."

"Improvements are also needed as per the customer's requirements."

"he list of hardware supported should be increased in the future."

"The solution functions as the marketing says, as long as you follow certain rules."

"I would like to see better performance graphs, maybe something that you can export outside to a different console, and maybe a little bit longer time period. The 18-hour maximum, or 24-hour maximum, is kind of short. Also, the hardware compatibility limitations are a little frustrating sometimes, but as everybody's starting to adopt vSAN more, you get more options for hardware."

"Because of virtual storage, the system reaches reserve storage for its functions. It also consumes a certain amount of storage, which then results in the creation of a fault tolerance for the system. All of this adds to a lot of capacity being consumed in terms of storage for each drive for vSan. I find this to be one drawback of using vSan."

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

"The price could be cheaper."

"Our licensing is renewed annually."

"Licensing fees are paid yearly."

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

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

"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 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

"It is not that expensive, and it is not even cheap. If it is designed in a proper way, it has good pricing, but if you do oversizing, the price will be high. There are different licensing models."

"The price is expensive."

"This solution is expensive. Nutanix provides us with Acropolis Operating System (AOS) along with its hardware, while VMware provides vSAN, vCenter, and vSphere which all have separate licenses and costs."

"The cost of the solution is high and if it could be reduced the customers would be very happy."

"It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components."

"I'd love for this product to be cheaper."

"Its price could be improved."

"VMware vSAN is an expensive platform. We purchase its yearly license."

Reduced risk: VMWare vSAN reduces the risk associated with digital transformations by utilizing existing tools, skill sets, and solutions.

Reviews from Real Users

Below are some reviews and helpful feedback written by PeerSpot users currently using the VMware vSAN solution.

PeerSpot user Yves S., CEO, Cloud Evangelist at Comdivision Consulting GmbH, says, “vSAN gives us a lot of advantages when we need to expand resources. We have an overall larger host infrastructure, and we split that up for specific customer test and use cases. In that specific scenario, we can easily add more hosts or reduce the number of hosts in the environment.”

A reviewer who works in Infrastructure Security explains, “The ease of use is great. The initial setup and upgrade process was pretty straightforward. And, technical support is great.”

Laurent N., Director at Softlogic, comments, "The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
