Comments on: If Hyperconverged Storage Is So Good, Why Is It Not Pervasive And Profitable?

Is hyperscale the same as disaggregated HCI? If not, what’s the difference? Is Commvault Hyperscale X an example of disaggregated HCI?

In reply to Jonathan Dahlin. Agreed. And at some point, when that is all normal, we can go back to calling it "infrastructure." HA!

I prefer converged infrastructure, disaggregated HCI, composable disaggregated infrastructure, and most of all hyperscale, over hyper-converged infrastructure.
Composable disaggregated infrastructure might be the final stage in the evolution of IT infrastructure.

Hyperconverged Storage may not have become pervasive simply because of its restrictions: the tie to a specific hypervisor preventing the flexibility of bare metal or native container support; and the high consumption of valuable compute server CPU, memory and networking resources. If your company needs more than a specific hypervisor (and therefore has to buy other external storage solutions) or it is worried about buying up to 30% more compute servers and associated software licenses to overcome HCI overhead, then pretty quickly Nutanix and VxRail become too limiting. That is why the external Storage market has stayed so strong so long. Nebulon smartInfrastructure (I admit I am a founder) was founded to address both these challenges in a server embedded solution that also gives on-premises IT customers a public cloud-like experience through a SaaS management interface. You can run any type of application, anywhere, on the servers of your choice. It may be the first server based solution that has the complete flexibility of external storage without the cost overheads of HCI or three tier architectures.

One factor limiting HCI is its modest scalability. I have never heard of of a HCI cluster greater than 64 nodes. All that metadata chatter to keep the distributed storage replicated and synchronized takes its performance toll. That makes it great for some point applications, but is hardly full elasticity and data center scale.

In reply to Alpha. Just ot say it is the well known Cassandra not "Cassendra" and i'm using Nutanix since 2015 without seeing all the "bugs" you are talking about, it's a robust and very well supported (NPS > 90 for the last 7 years) solution compared with all the competitors, so i guess your comment is a fake.

The real reason it hasn’t hockey sticked is because of 2 things, both people related: 1.IT Staff doesn’t want to learn new things- why bother when you can sit happily using vcenter your whole career, and 2. Job protection. Legacy storage admins are scared to death of HCI as it makes them mostly unnecessary, but to be fair SSDs started that trend even in 3tier. Who calculates spindles now? Lol. My vdi team owns our infra completely and we went all in on nutanix and it’s been great not having to engage a storage admin to carve out luns anymore.

If you have ever used Nutanix, you wouldn’t have wrote such a misleading article. Nutanix is half baked product, full of bugs and failures at each component level. Be it Stargate, Cassendra, etc. They have very basic level of logical failures at each level and even though theg say that they have one click upgrade process, in reality its all manual because there dark bundles and upgrade process have too many issues which never goes as advertised.

Your focus is on Nutanix and not HCI in general. Cisco HX, Dell VXRail, Rancher Harvester, VMware VSAN….

So many ways for customer to solve their problems, but HCI’s Working pretty well on our end. Just sayin. #vxrail
