We performed a comparison between IBM Spectrum Virtualize and Nutanix Unified Storage 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."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 lowers cost. It does so by getting more efficient use out of the technology behind it."
"It has the ability to seamlessly move hardware in and out as we refresh technology."
"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."
"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."
"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."
"They have well-documented best practices and the interface is good."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"The real-time alerts generated by this system enable us to swiftly address and mitigate such threats."
"We have been able to save local disk space by using Data Lens. We upload 18 GB to the cloud and are able to save 20% to 25%."
"My opinion is that this solution has very good stability."
"The integration with Prism Central makes it a lot easier to manage, so we just have a single pane of glass location that we can go to. We do not have a separate admin console or anything that we have to use."
"The reliability and availability are the most valuable features. Reliability is important because it can run my workloads. I need to be able to take advantage of the VMs that are executing on the storage. It has to be reliable. It's also important to have the storage available for scaling VMs on demand."
"What I like most about Nutanix Files Storage is the way it makes copies of the data. The solution also has high availability, which is excellent. Another valuable feature of Nutanix Files Storage is self-service, so users won't have to depend on the IT team much."
"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"Adding features for data deduplication is one area of improvement."
"The Storwize port is not so stable."
"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."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"The disk reliability is not that good."
"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."
"The management is pretty clunky, in my opinion. It could be a little bit better."
"The escalation process with technical support could do with some improvement."
"It is challenging to configure access control settings."
"The solution should increase its storage capabilities."
"The GUI is not user-friendly for new users and has room for improvement."
"From a management side, the one thing I would prefer is if it were a bit less expensive for smaller enterprises. It's a bit costly. If they provided flexible modules where you could pick and choose features, and only pay for what you use, that would be an improvement."
"The current hardware is not as dense as it could be. In our deployment, we have 2 PB per site, and we have to have 24 nodes. That's a lot of cabling and network ports that we use up. More dense nodes would be better."
"Allowing the use of the Gflag compromises the integrity of the Nutanix system and its established standards."
