We performed a comparison between IBM Spectrum Virtualize and Nutanix Cloud Infrastructure (NCI) 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."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."
"One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those."
"The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."
"It provides transparency, because of its advanced copy features."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"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."
"The scalability is very good. It can handle anywhere from very small to large enterprise class."
"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."
"Being able to upgrade our entire cluster with the click of a button during business hours with zero downtime has made managing our infrastructure so easy."
"The solution remains stable across versions."
"The most valuable feature is the integration of all parts in Prism Element, the browser-based management tool."
"I definitely find the reduced power consumption very valuable."
"Performing a Nutanix software upgrade is a very simple and non-disruptive process."
"Nutanix has the best virtual desktop infrastructure."
"The level of statistical performance data that it can confirm in real-time is extremely useful. I can see what my VM’s hosts and guests are doing from a single pane of glass and identify issues before they would otherwise become apparent."
"The solution is well integrated with other vendors."
"GUI should be developed in HTML5 as opposed to Java."
"The Storwize port is not so stable."
"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."
"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."
"Level 1 technical support needs improvement."
"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."
"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."
"Nutanix now supports four hypervisors but they are not all at feature parity."
"Storage utilization and optimization should be better."
"Notifications could be improved as they're not currently very useful."
"Compatible with third party hardware, but it's still very limited."
"There is a feature that exists used for disaster recovery, but it requires an extra license. It should be included with the regular normal standard license."
"The ability to create clusters faster would be nice to see in a future release."
"It would be great if they could improve the GUI features."
"The latency needs improvement"
