We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"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.""The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver.""When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization.""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.""The scalability is very good. It can handle anywhere from very small to large enterprise class.""It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly.""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.""It provides transparency, because of its advanced copy features."

"The most valuable feature is the simplicity of its scalability: being able to grow it without having to make sure you get the right disks and the right nodes. The solution is also easy to manage. It's all right there in the vSphere Client. You're not going through multiple things. You don't have to know, once you've created the vSAN node. You add storage, it sees it, and you create your data storage from there. Everything is right there for you.""We are finding that vSAN is a lot more scalable and adaptable, because we can go in with hybrid arrays for our lower-end storage needs or with all-flash versions of vSAN for places where we need more performance, and it's coming in at a lower cost point than an actual traditional array.""VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products.""High availability is a valuable aspect of this solution.""The performance of VMware vSAN is very good.""Technical support has been very good. They respond pretty fast, especially if we have a critical issue. Their responses have been great.""It uncoupled the idea of proprietary technology and component capabilities. It is basically a proprietary technology for a cost-effective infrastructure.""Instead of going for SAN storage, customers can use the scale-up and scale-out features of VMware vSAN."

Cons
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented.""For improvement considerations, I would probably say multiple sites.""I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky.""Adding features for data deduplication is one area of improvement.""I would like to see more baseline replication and integration with the operating system between Vmware and IBMI.""There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of.""The disk reliability is not that good.""The Storwize port is not so stable."

More IBM Spectrum Virtualize Cons →

"It would be ideal if the solution offered some intelligent monitoring.""The main problem we had was hardware compatibility, finding the right hardware that was certified.""More focus has to be put on deduplication and compression with a hybrid architecture.""Troubleshooting tools could be improved.""The monitoring feature in VMware vSAN could be better.""We would like to see even more storage capacity.""There is always a challenge with their firmware.""I would like to see some of the more traditional SAN functions that are out the now. I can list them: being able to Snapshot on the back-end, better de-dupe, and better compression. Those are the major ones."

Pricing and Cost Advice
  • "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 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."
  • "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."
  • "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."
  • "This solution came as an additional cost for the TSM package we chose."
  • More IBM Spectrum Virtualize Pricing and Cost Advice →

  • "The first 1-2 years of purchasing vSAN will be expensive. Thereafter, the longer you are running it, the more cost savings you will have."
  • "Its reasonable, compare with other storage vendors"
  • "Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."
  • "​I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee.​"
  • "Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product."
  • "We have increased our user productivity."
  • "What made us go with this solution was price point. When you can utilize existing storage infrastructure, and not have to continually purchase new SAN products out there that are going up in price as time goes by, then it's a wonderful thing."
  • "We did consider other hyperconverged solutions. It usually came down to price. vSan was the most cost effective thing."
