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."
"The most valuable feature is the fact that the nodes are Active/Active, and allow us to do upgrades on any node without any downtime."
"When we need additional storage but want to keep the size of the SANs manageable, the StarWind Virtual SAN has allowed me to do everything needed."
"The most important feature is the ability to experience the loss of one node or one storage device, and not lose the entire cluster."
"The StarWind Virtual SAN management console is intuitive and easy to use."
"Active-active work mode leads to true redundancy of storage and allows us to distribute the load between multiple nodes."
"We can lose a site or even two of our three, and we would lose no data and have no outage."
"The most valuable feature for us is having the ability to configure our local storage using a limited number of disks and using the StarWind VSAN software to keep the cluster nodes in perfect sync."
"In addition to the main functions of the software, I want to note the excellent work of technical support."
"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."
"It would be nice if we could designate pools, or tiers, for storage of different speeds, and then assign rules to new VMs that would automatically place them into the proper pool."
"The only thing that I have any difficulty with is that in order to perform upgrades, it is required that the SANs be detached from the Hosts before that can happen."
"We would like to see the documentation more fully developed."
"It would be great if the Linux version of the management console offered the same features as Windows."
"Some configuration options still demand service restarting."
"Server-side snapshots are one thing the Linux appliance can't do yet."
"The system performs as expected, but we're always looking for performance improvements regarding the best utilization of NVMe disks."
"Perhaps the developer should refine the product management through PowerShell."
"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."
"Once you buy the license, you are free to build your own hardware solution based on your needs."
"I would suggest that you download the free version, deploy in your lab, and play with it."
"This solution has a great price for the functionality."
"Licensing is based on nodes rather than TBs, which means that the users are free to increase storage capacity without putting thought into licensing."
"The free version is great to use for labs or test environments."
"There are two tiers of support and in my opinion, support is worth the cost."
"Licensing is easy and the whole package is cost-effective."
"The cost takes into account the number of nodes, so the size of the storage is not important."
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.
For SMB, ROBO, Cloud and Hosting providers, who look to cut down virtualization expenses, our solution is StarWind VSAN. It is software that eliminates any need in physical shared storage by basically “mirroring” internal hard disks and flash between hypervisor servers. There is less hardware to buy in general, consequently less money is spent on purchase and maintenance. The existing hardware is used with maximum efficiency, so there is no money wasted at all.
StarWind Virtual SAN targets those who already have servers, or are bound to a particular vendor list to buy from. In case there is a new virtualization infrastructure to be built from scratch, StarWind offers a much better way – StarWind HyperConverged Appliance. It is a turnkey solution complete with hardware and software, powered by StarWind Virtual SAN. Those who need to build and maintain virtualization infrastructure at little to no expense, may be interested in StarWind Virtual SAN Free.
