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."It has the ability to seamlessly move hardware in and out as we refresh technology."
"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."
"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."
"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 most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."
"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."
"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 administration console, automation, and the first cluster are all valuable features."
"The most valuable features of Nutanix Acropolis AOS are storage and hyper-converged. The solution is easy to use and the administration is very good."
"The solution is very stable. We haven't had any issues."
"One of the main features of the solution is that it works on many hypervisors. It is a big advantage. Additionally, the solution is compatible with VMware and Hyper-V, and the management interface, which is called Prism, is very intuitive and user-friendly."
"In addition to the hyper-converged infrastructure, most of our clients are pleased with Acropolis' built-in replication in terms of the DR setup. Our clients also like Prism Central's advanced management and analytics, and many find Nutanix Flow and playbooks incredibly useful."
"Nutanix Acropolis AOS is stable. We didn't receive any concerns regarding any problems, The customers have no concerns about the reliability."
"The configuration is easy, and it's flexible."
"Best features are around data locality, compression, and deduplication."
"Anything which improves performance and the ability of our systems would be a nice."
"The Storwize port is not so stable."
"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."
"The disk reliability is not that good."
"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 already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."
"Level 1 technical support needs improvement."
"In general, the migration is complicated. Though, it is case-by-case."
"In Thailand, there really isn't a cloud version of Nutanx available to us."
"It would be great if they could improve the GUI features."
"It is a CentOS-based operating system, but CentOS releases security patches almost every week or every other week. However, Nutanix releases their upgrade at three or four month intervals. According to my organization's SLA, if a critical patch is released during that time, then I need to implement the patches within 30 days. If it is a standard patch, then I need to patch it within 60 days. Since that is my SLA, I cannot meet my SLA for security because Nutanix will not release the upgrade within these 30 days. Between the critical patch release and the Nutanix release, my customers say they are vulnerable and I am accepting the risk while the SLA is breached."
"I'm not very technical, so I don't know if there are any features that are really lacking. Our customers seem pleased with it, and I haven't heard of any downsides."
"Nutanix has a complex infrastructure, we have customers that consider VMware instead. Additionally, the performance could be better."
"They should support more VM, which is not currently supported."
"I would like better integration of XenServer into the AOS and Prism Central."
"The only problem is that not many operating systems are supported on the AOS hypervisor. They need to probably increase the support on multiple operating systems. As of now, a very limited number of operating systems and patch levels are supported on AOS."
