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 most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

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

"The initial setup is pretty easy and simple."

"The initial setup is pretty quick."

"Speed and ease of use are the two most valuable features."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"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 product is scalable and easy to expand."

More Pure Storage FlashBlade pros

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

"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."

"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."

"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."

"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."

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

"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."

"In my opinion, the quick restore, the low latency, and the ease of use are some of the most valuable features."

More IBM Spectrum Virtualize pros

"The flexibility is most valuable. Being able to manage things quickly if something goes wrong is also valuable. Very recently, we had one node that went down due to a power problem, but there was really no major impact on the systems running on top of it."

"Being hyperconverged, it simplifies what equipment we have to buy."

"I have used VMware for 15 years and I never had any problems with stability."

"We didn't only choose vSAN; we chose VMware because of SR-IOV, which is more on the hypervisor level and not on the vSAN storage. It's part of the whole system."

"The most valuable features of vSAN are its simplicity to deploy and that we can use commodity disks in our servers without complexity or need for external storage arrays or storage specialists on our teams."

"VMware vSAN is a global solution, so we can manage all the storage solutions in one place. It's embedded in VCI solutions."

"Technical support is very helpful and very good at resolving issues."

"The implementation is simple, it was very straightforward. It took us approximately three weeks because it was installed in four locations."

More VMware vSAN pros

Cons

"The features provided for SMB customers are limited."

"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."

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

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

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

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"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 speed could be improved."

More Pure Storage FlashBlade cons

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

"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."

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

"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."

"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."

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

More IBM Spectrum Virtualize cons

"While I like the replication and compression features, there is a problem with them running too slowly."

"Its installation should be easier, and its price should be cheaper. It would be good for the product if they can include the data locality feature."

"The technical support, it's not satisfactory. Whenever we raise a ticket it takes a lot of time to have an engineer get involved sometimes, or we receive a less experienced engineer. We then have to repeat the situation to the next engineer which all takes time."

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

"A vSAN cluster must have compression and deduplication to be an all-flash array, but it's not supported with a hybrid array. Deduplication and compression work better with an all-flash array, so I think that VMware should give customers the option to activate and support this feature for hybrid arrays. Other products like Nutanix support this."

"vSAN has a significantly higher license cost post-merger."

"As no product is 100% perfect, the price for VMware vSAN could still be improved, though it is good when compared to some of its competitors."

"Reporting currently depends on third party applications and that could be improved."

More VMware vSAN cons

Pricing and Cost Advice

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

"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."

"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."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"The price is a little high."

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

"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 price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

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

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

"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."

"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."

"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."

"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

"Its price could be improved."

"The solution requires a license. The payment is on a yearly basis and It is not overly expensive."

"Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product."

"The product’s pricing is a bit higher than other solutions."

"The price of VMware vSAN is expensive and there is an annual license required."

"Its reasonable, compare with other storage vendors"

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

"I have been told that if I used VxRail it would be cheaper than the system we are using now with buying the products separately. The solution is expensive overall."

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."
