ESXi performance

Single ESXi performance

Test migration using the same ESXi host.

In each iteration, the total VMs are increased, to display the impact of concurrent migration on the duration.

The results show that migration time is linear when increasing the total VMs (50 GiB disk, Utilization 70%).

The optimal number of VMs per ESXi is 10.

Table 1. Single ESXi tests

Test Case Description	MTV	VDDK	max_vm inflight	Migration Type	Total Duration
cold migration, 10 VMs, Single ESXi, Private Network [1]	2.6	7.0.3	100	cold	0:21:39
cold migration, 20 VMs, Single ESXi, Private Network	2.6	7.0.3	100	cold	0:41:16
cold migration, 30 VMs, Single ESXi, Private Network	2.6	7.0.3	100	cold	1:00:59
cold migration, 40 VMs, Single ESXi, Private Network	2.6	7.0.3	100	cold	1:23:02
cold migration, 50 VMs, Single ESXi, Private Network	2.6	7.0.3	100	cold	1:46:24
cold migration, 80 VMs, Single ESXi, Private Network	2.6	7.0.3	100	cold	2:42:49
cold migration, 100 VMs, Single ESXi, Private Network	2.6	7.0.3	100	cold	3:25:15

Multi ESXi hosts and single data store

In each iteration, the number of ESXi hosts were increased, to show that increasing the number of ESXi hosts improves the migration time (50 GiB disk, Utilization 70%).

Table 2. Multi ESXi hosts and single data store

Test Case Description	MTV	VDDK	Max_vm inflight	Migration Type	Total Duration
cold migration, 100 VMs, Single ESXi, Private Network [2]	2.6	7.0.3	100	cold	3:25:15
cold migration, 100 VMs, 4 ESXs (25 VMs per ESX), Private Network	2.6	7.0.3	100	cold	1:22:27
cold migration, 100 VMs, 5 ESXs (20 VMs per ESX), Private Network, 1 DataStore	2.6	7.0.3	100	cold	1:04:57

Different migration network performance

Each iteration the Migration Network was changed, using the Provider, to find the fastest network for migration.

The results show that there is no degradation using management compared to non-managment networks when all interfaces and network speeds are the same.

Test Case Description	MTV	VDDK	max_vm inflight	Migration Type	Total Duration
cold migration, 10 VMs, Single ESXi, MGMT Network	2.6	7.0.3	100	cold	0:21:30
cold migration, 10 VMs, Single ESXi, Private Network [3]	2.6	7.0.3	20	cold	0:21:20
cold migration, 10 VMs, Single ESXi, Default Network	2.6.2	7.0.3	20	cold	0:21:30
