With the release of vSphere update 1, there is major shift in the supported compute maximums as summarised in table below.
| vSphere 7 | vSphere 7 Update 1 | |
| Virtual CPUs per VM | 256 | 768 |
| Memory per VM | 6 TB | 24 TB |
| CPUs per host | 768 | 768 |
| Memory per host | 16 TB | 24 TB |
| Hosts per cluster | 64 | 96 |
With vCenter Server 7.0 Update 1, scalability for vSphere Lifecycle Manager operations with ESXi hosts and clusters is increased as follows:
- 64 supported clusters from 15 clusters.
- 96 supported ESXi hosts within a cluster from 64. For vSAN environments, the limit is still same i.e. max 64 hosts
- 280 supported ESXi hosts managed by a vSphere Lifecycle Manager Image from 150
- 64 clusters on which you can run remediation in parallel, if you initiate remediation at a data center level from 15 clusters.
