We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
"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 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."
"This synchronization is easy with StorMagic, and we can establish availability between servers."
"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."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"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."
"The only improvement area I can see is their licensing. For example, the memory caching feature is only available in an advanced license. Normally, it's in a standard license. It would be better if they had memory caching features in the product. Some backup features should also be in the product"
"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."
"It's fairly cheap when compared to other options. But it can be improved as some features may not be available in the standard license. The vendor positions it as an edge product, so it isn't suitable to compare with VMware vSAN or Nutanix because that's another product altogether."
IBM Spectrum Virtualize is a dependable solution that improves data value, security, and simplicity for new and existing storage infrastructure. Proven over 12 years in thousands of deployments, its innovative virtualization capabilities help organizations achieve better data economics by supporting new workloads that are critical to their success. IBM Spectrum Virtualize software helps make new and existing storage more effective and standardizes functions traditionally deployed separately in disk systems for greater flexibility and potentially lower costs.
StorMagic SvSAN simplifies storage at the edge. It is a virtual SAN, virtualizing the internal storage of two servers and creating an active-active mirror that ensures an exact copy of data resides on both servers at any time. Needing just two nodes in each cluster, using any x86 server, any CPU and any storage combination, SvSAN gives you the flexibility to deploy lightweight, low cost highly available storage as you wish.
A single, incredibly lightweight witness provides quorum to as many as 1000 SvSAN clusters and they can all be deployed and managed from a central location. Stretch your SvSAN clusters across entire cities for added resiliency. Deploy on VMware vSphere, Microsoft Hyper-V or Linux KVM hypervisors and avoid vendor lock-in. Leverage sophisticated caching algorithms when superior performance is required. If security is a priority, implement StorSecure - SvSAN's integrated encryption and key management feature. And if redundancy is a concern, deploy three nodes per cluster to withstand two node failures and still keep your applications online.
IBM Spectrum Virtualize is ranked 9th in Software Defined Storage (SDS) with 3 reviews while StorMagic SvSAN is ranked 18th in Software Defined Storage (SDS) with 1 review. IBM Spectrum Virtualize is rated 8.6, while StorMagic SvSAN is rated 0.0. The top reviewer of IBM Spectrum Virtualize writes "Enables us to build an infrastructure and replace storage with no disruption to our hosts whatsoever". On the other hand, the top reviewer of StorMagic SvSAN writes "A software-defined storage solution with a useful synchronization feature". IBM Spectrum Virtualize is most compared with VMware vSAN, Dell EMC VPLEX, IBM Spectrum Scale, DataCore SANsymphony SDS and NetApp Cloud Volumes ONTAP, whereas StorMagic SvSAN is most compared with VMware vSAN, StarWind Virtual SAN, DataCore SANsymphony SDS, HPE SimpliVity and Veeam Backup & Replication.
