We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"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.""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.""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.""I like that it can virtualize more than three hundred storage providers."

"Stretched Cluster is one of the big features that we use across multiple data centers.""If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now.""The vSAN features we've found most helpful are live application migrations and storage policies. It has storage, policies, application, and DRS policies. Automation is there.""There is not a lot of maintenance required.""We find it easy to deliver this solution.""vSAN is very integrated.""When we do to do more scaled load testing, we can run more dense workloads and still have the same results across all specific nodes""The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."

Cons
"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.""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.""I would like to see more baseline replication and integration with the operating system between Vmware and IBMI.""t is limited in terms of a single system to eight nodes or four, what they call IO groups."

More IBM Spectrum Virtualize Cons →

"The solution could maybe improve failure protection.""Troubleshooting tools could be improved.""It can be very expensive.""If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much.""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.""They should make the software updates easier. We should be able to upgrade it more easily.""We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases.""They should provide Deduplication and Compression over the hybrid drives."

Pricing and Cost Advice
  • "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."
  • "I think it is a good value for the price."

  • "If they could reduce the cost, it would be better. Licensing costs are something that they could take care of. If you are a smaller and strong IT team, then VMware vSAN is a very good product. If you want to expand in the service provider space, then you will have to go for an open-source solution like OpenStack. We are now looking at OpenStack because we sell licensing costs. We are a service provider, so the IT component data is a substantial component in our overall costing. We feel that OpenStack might help us to cut down the licensing cost. Therefore, we are looking at SAS storage instead of vSAN. SAS is open source, but it is not wise to have open source without having the backend support. We are using RedHat SAS, and it is an open-source solution. You can also have a free version, but we are using it with support from RedHat so that we have somebody to back us up in case we have a problem. If you do normal business, then IT expense is 1% or 2% of the total turnover. The higher licensing costs sometimes don't make difference to the big companies who are not service providers and are using it only for their internal use. For them, the IT cost is 1% or 2%, but for an IT service provider, the IT costs will go up to 15% to 16% of the total cost of the operations. This is where the licensing costs become irrelevant. For example, the licensing cost of using VMware, VC, and vSAN is 8% of my monthly revenue. Every month, I pay about $35,000, and, with the revised plan, it will be something like $50,000 or revenue of 600k per month, which means almost 8% of the revenue is going into VMware licensing. In a very competitive world, 8% as a cost element is huge. So, if I can bring it down to 2%, I save 6% in revenue expenditure. In terms of profit, 6% of 30% is something like another 25% increase in my profit. My profit can be almost 25%. It would be 20% to 25% in case I am able to handle the licensing costs and bring them to a very low level. Because these IT costs are substantial for us, that is why we are going with OpenStack. OpenStack has a limitation that it requires more hardware. There will be some increase in the hardware cost, but overall we will save 5% to 6% of our licensing cost by using OpenStack."
  • "It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components."
  • "The price is expensive."
  • "It is an expensive solution. There should be more flexible with licensing to allow small businesses the essentials of the solution's features."
  • "The price of vSAN could be lower."
  • "It is too expensive."
  • "It is expensive, but you get what you pay for."
  • "The price is okay."
