Eric Black

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

"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's very easy-to-use."

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

"The initial setup is pretty quick."

"The solution provides many controllers."

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

"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."

More Pure Storage FlashBlade pros

"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."

"IBM offers excellent customer service."

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

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

"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."

"It provides transparency, because of its advanced copy features."

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

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

More IBM Spectrum Virtualize pros

"It is very well known in the industry, and there are a lot of technical resources around it. This is a big thing for me because, at the end of the day, when you implement it, you need to support it."

"Easy to deploy and manage."

"The product's initial setup phase was very straightforward."

"Everyone uses virtualization to more efficiently utilize hardware resources. That's the main point of vSAN and VMware."

"I like the orchestration feature."

"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."

"The setup is straightforward."

"The ability to have an HA cluster in the absence of a shared storage device or SAN."

More VMware vSAN pros

Cons

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

"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."

"I would like to see more monitoring capability included in the next release of this solution."

"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 features provided for SMB customers are limited."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"Its configuration should be easier."

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

More Pure Storage FlashBlade cons

"The disk reliability is not that good."

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

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

"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."

"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."

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

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

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

More IBM Spectrum Virtualize cons

"We are facing some problems with updates with the VMware vSAN. When we upgraded from version 6.5 to 7, we have been faced with many problems. They have been deploying many hotfixes for this version, and they need to continue to improve this version."

"The ability to access SAN environments with fiber channels (or even NVMe) would be a good addition."

"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."

"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."

"In a future release, they can bring in the object storage capabilities to this solution. Currently, there is not any compatibility."

"The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that."

"On the DevOps side, if there could be more automation it would be more helpful."

"The pricing model is sometimes a challenge for us because their licenses are very costly."

Pricing and Cost Advice

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

"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 rate the tool's pricing a seven to eight out of ten."

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

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

"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."

"Licensing fees are paid yearly."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

"The entry point of pricing for this product is the most amazing price ever in the industry."

"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."

"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 could be cheaper."

"The price of the solution package depends on the nodes and other factors. The cost some of our customers paid was $500,000. The licensing cost for the components is very good."

"Cost-wise, the Nutanix licenses were cheaper, but in terms of the hardware, there was some contention around it. So, in terms of implementation, the way Nutanix was projecting the implementation on their end was that there were a lot of open-source admin platforms. vSAN is a licensed product in VMware, and Nutanix was proposing a KVM solution, which is open source. That's why their pricing was a bit cheaper, but when we were trying to compare it with an enterprise version of their management platform, it boiled down to the VMware vSAN being most effective in the long run."

"VMware vSAN is a little bit expensive and we pay annually. We have an educational institute where we receive discount prices from VMware. We do receive a reasonable discount but it's still expensive."

"The solution is relatively expensive compared to similar products."

"The only problem I have with VMware is the price. It is a good product, but it is expensive."

"The vSAN licensing is not an inexpensive product. It does cost more than hypervisor."

"vSAN has many versions with standard and advanced including Enterprise and Enterprise Plus. Regarding the Enterprise and the Advanced, it could be lower."

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."
