Resilient with seamless failover, and the support is helpful
Built-in Notification would really help and as I understand, their new release has this now. A mobile app to sync up for overview and status would really be helpful. Also, it would be helpful if the software had a few more guides and links/videos on how-to's. An "Update available" notification within the software would also be helpful and a guided wizard to do the upgrade properly would also be nice and efficient. A better visual of the SAN storage/actual storage and how it is used would be good, especially when it comes to where the files are located on the disk.

What you might not know about Nutanix that makes it so unique
Nutanix has the potential to replace most of today's traditional storage solutions. These are classic hybrid SAN arrays (dual and multi-controller), NAS Filers, newer All-Flash Arrays as well as any object, big data etc. use cases. For capacity, it usually comes down to the price for large amounts of data where Nutanix may offer higher-than-needed storage performance at a price point that isn't very attractive. This has been addressed in the first step using storage-only nodes which are essentially intelligent disk shelves (mainly SATA) with their own virtual SDS appliance preinstalled. Storage nodes are managed directly by the Nutanix cluster (the hypervisor isn't visible and no hypervisor license is necessary). While this is going in the right direction, larger storage nodes are needed to better support "cheap, big storage" use cases. For typical big data use cases today's combined compute and storage nodes (plus optionally storage-only nodes) are already a very good fit! The Nutanix File Services (Filer with active directory integration) are a very welcomed addition customers get with a simple software upgrade. Currently, this is available as a tech preview to all Acropolis Hypervisor (AHV) customers and will soon be released to ESXi as well. This is one example of a service running on top of the Nutanix distributed storage fabric, well integrated with the existing management layer (Prism) offering native scale-out capabilities and One-Click upgrade like everything else. The demand from customers for a built-in filer is big, they are looking to not depend on legacy filer technology any longer. We are looking forward to seeing this technology mature and offer more features over the coming months and years. Another customer need is to be able to consume Nutanix storage from outside the cluster for other, non-Nutanix workloads. These could include bare metal systems as well as non-supported hypervisors (e.g. Xen Server etc.). This functionality (called Volume Groups) is already implemented and available for use by local VMs (e.g. Windows Failover Cluster Quorum) and will soon be qualified for external access (already working from a technical point of view including MPIO multi-pathing with failover). It will be interesting to see if Nutanix will allow active-active access to such iSCSI LUNs (as opposed to the current active-passive implementation) with the upcoming release(s). Imagine if you upgraded your Nutanix cluster (again this would be a simple One-Click software upgrade) and all of sudden you have a multi-controller, active-active (high-end) storage array. (Please note that I am not a Nutanix employee and that these statements describing possible future functionality are to be understood as speculation from my side which might never become officially available.)

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:


"The most valuable feature is the managed service, which has been an important part of monitoring our critical infrastructure."
"Active-active HA provides top performance and redundancy."
"It has been extremely stable for the three years we've been running it."
"StarWind Virtual SAN is essentially hardware agnostic, allowing us to build out a specific hardware layer based upon the customer's unique requirements."
"We are able to do maintenance by bringing down one node at a time, rather than having to schedule a complete shutdown."
"StarWind Virtual SAN is a very mature software that supersedes its capabilities with my use cases."
"It includes every feature that a traditional SAN offers and so much more."
"The access to our data is quicker and cheaper than it used to be in a traditional storage system."
"The solution is scalable."
"The program is stable."
"Dell PowerFlex is a one-stop-shop solution. Storage, compute, network, application monitoring, and support cases are all combined into one solution. It's very easy to administer compared to when you have a reference architecture where you need to design and build everything yourself. You would also then have to work with multiple vendors."
"Dell PowerFlex is a complete hyperconverge that makes automation easy to manage and extremely stable."
"We're doing a lot of VMware for IT so this solution is really valuable from a VMH point of view. We're trying to assist our customers mainly with management, because that's what they want. The most important aspects are ease of management, as well as ease of configuration, allowing them to attach additional nodes and resources for the applications."
"We've had no issues with scaling the solution."
"The most valuable feature is high availability."
"The catalog of APIs for automation has been most valuable, although they are quite limited."
"One-Click Upgrade and Foundation is the most valuable feature. One-Click Upgrade makes upgrades and LCM a breeze. Prior to Nutanix One-Click Upgrade, upgrades and LCM were overly cumbersome and time-consuming. Foundation provides an easy, yet very structured, approach to cluster modification (adding or removing nodes)."
"It gives us a single dashboard to control multiple sites and multiple zones. It helps to do things on a single platform and data sharing is quite easy. The network and the security are easy to manage."
"The hyperconvergence service, as well as the DR solution, are game-changers for Nutanix."
"You need to send commands through the command-line interface(CLI). This could be improved. The commands are done better in VMware."
"The scalability is great."
"It supports multi-cloud integration that includes AWS, Google, and Azure."
"The solution remains stable across versions."
"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."


"We would like the documentation to be more complete. Most items are covered, but if you don't know something, you may need to contact their support."
"For me, the product could be improved by it being made cheaper."
"A great feature would be a wizard and to include a new disk in the SAN. At the moment, including a new disk requires several steps - some that must be done at the OS level and others in each node."
"In all areas the product could be made faster."
"They require more media visibility."
"The system failovers properly on its own without too much worry."
"I would definitely like to see quite a bit more on the monitoring side of things."
"There should be some kind of active monitoring connected to StarWind vSAN, so you will be able to act when needed."
"We're also running Hyper-V virtual machines. But we recently discovered that migration of the Hyper-V virtual machines is a bit challenging. Maybe if Dell EMC can come out with a tool that will make it very easy for us to migrate the Microsoft Hyper-V machine, that may be an improvement."
"Licensing restrictions can be frustrating."
"I think there might be some room for improvement when it comes to pricing, because although I know how to convert customers, at the end of day, it's quite expensive. Sometimes your feature architecture is still coming out much cheaper than hardware costs for your infrastructure."
"The solution must be more flexible."
"They should provide continuous support for data migration."
"The storage capability must be improved."
"The tool needs to improve its storage. It should also make migration to the cloud easier."
"Including instrumentation would be a helpful improvement."
"They have offered some new features that I have not deployed so I assume that these issues might have been addressed already, but, at my time there was a networking problem."
"Storage utilization and optimization should be better."
"Notifications could be improved as they're not currently very useful."
"Nutanix Cloud Infrastructure's cloud platform management software could be improved so that I can manage my load between the cloud and on-premises."
"The reporting section of the dashboard could be improved to include more detailed reporting about the servers."
"Nutanix Cloud Infrastructure's LTS version needs to be more reliable."
"To have internal stability, we needed to network the solution ourselves. Performance depends on the application. Performance could be the lack of IOPS, memory and CPU and configuration issues."
"The price could be lower."

Pricing and Cost Advice

"This solution is very accessible and the pro-level for support is well worth the cost."
