We performed a comparison between IBM Spectrum Virtualize and StarWind Virtual Tape Library based on real PeerSpot user reviews.
Find out in this report how the two Software Defined Storage (SDS) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It lowers cost. It does so by getting more efficient use out of the technology behind it."
"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."
"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."
"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."
"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."
"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."
"StarWind VTL allowed us to back up to virtual tape that was created within Veeam and upload the tape to the cloud."
"I like the fact that we can simultaneously upload the virtual tapes to different cloud providers, and the settings can be adjusted to speed up the upload times even further."
"The solution made our backups way more reliable."
"The most valuable feature of the StarWind Virtual Tape Library is the archiving to the AWS cloud."
"It is a stable solution."
"The solution could have a better built-in performance monitor."
"The disk reliability is not that good."
"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."
"In general, the migration is complicated. Though, it is case-by-case."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"GUI should be developed in HTML5 as opposed to Java."
"The Storwize port is not so stable."
"The main thing that I felt could be improved was having an estimated time of completion for the virtual tape uploads to the cloud."
"The initial installation can be complex and should be simplified."
"I am not sure if this is a limitation of my physical hardware or if it is the software itself. However, I would like the throughput to be faster."
"The solution's training process and online documentation could be more thorough."
