Different Hypervisors – Hyper Convereged

Different Hypervisors – Hyper Convereged

By Cobus Smit – 13 Sept 2019

Companies use different hypervisors to run some kind of virtulization on hyper converged. This is part to get the footprint smaller and make management easier. It is not an easy task to compare these vendors as all do a pretty good job.

Let’s have a look at the good and the bad on some of it. (VMware, Hyper-V & Nutanix AHV):

VMware:

Used by these HCI vendors- Dell EMC, NetApp, HPE, VMware, Hitachi

The Good:

  • VMware is trusted and tested for the last couple of years
  • Easy to use and deploy servers and reliable
  • Balancing of the resources is done very well.
  • Easy to attach external storage and lots of options
  • Great support and documentation
  • VSAN – software-defined storage on the hosts
  • Broad range of hardware support.
  • Strong VMware integration
  • Policy-based management

The Bad:

  • It can get expensive. Licensed per socket
  • Migration between different CPU types
  • Sometimes difficult to update
  • HTML 5 vs client for management
  • Single hypervisor support
  • Very limited native data protection capabilities

Hyper-V:

Used by these HCI vendors- Fujitsu

The Good:

  • Easy to manage for a Windows administrator especially with 2019 edition
  • Not as expensive as VMware but is catching up in 2019
  • It got a lot better with the newer versions
  • Integrated with your windows environment
  • Support is ok
  • Storage space direct – software-defined storage on the hosts
  • Broad range of hardware support
  • Strong Microsoft integration
  • Great simplicity to deploy

The Bad:

  • It is not as stable as VMware
  • It still lacks support for some features like GPU sharing and some storage options
  • Snapshots not as stable as VMware
  • Lots of manual work
  • Backups and replication (VM-live migration) not as smooth as VMware
  • Single hypervisor support
  • Limited native data protection
  • Dedup/compr not performance optimized

Nutanix:

Used by these HCI vendors- Nutanix, HPE

The Good:

  • It is easy to deploy servers and it is easy to use
  • It can work with different hypervisors
  • You can have data replication through replicas
  • It has pretty good deduplication and compression but it is complex.
  • Documentation is not bad
  • Software-defined storage on the hosts and storage move with VMs
  • Extensive platform support
  • Native file and object services
  • Manageability

The Bad:

  • Replication is not where it is supposed to be.
  • The software-defined storage can only handle normal workloads
  • Some network changes like VLANs on VMs require machines to be shut down.
  • Moving around storage is not as easy as VMware.
  • Storage reporting can be enhanced.
  • Complex solution design
  • No QoS
  • Complex dedup/compr architecture
