Restrictions
This table is meant to outline restrictions in the software dictated by licensing or capabilities.
| Name | Maximum host cores / CPUs | Maximum host memory | Maximum host disk volume size | Maximum number of guest VM running | Maximum number of logical CPU per VM guest | Maximum amount of memory per VM guest | Maximum number of SCSI + IDE disks per VM guest | Maximum disk size per VM guest |
|---|---|---|---|---|---|---|---|---|
| Containers, or Zones | 144 cores / 72 CPUs | 4 TB | No limit | 8191 | No limit | No limit | No limit | No limit |
| VMware Player 4.0 | 4 cores | No limit | N/A | ? | 8 | 8 GB (32-bit); 64 GB (64-bit) | ? | 2 TB |
| VMware Server 2.0 | 16 CPUs | No limit | N/A | 64 | 2 | 8 GB | 4 IDE; 60 SCSI | 950 GB |
| VMware vSphere Hypervisor (ESXi) 4.1 | 160 logical cores | 1 TB | 2 TB minus 512 bytes | 320 | 8 | 255 GB | 4 IDE; 60 SCSI | 2 TB minus 512 bytes |
| VMware vSphere ESXi 5.0 | 160 logical cores | 2 TB | 64 TB | 512 | 32 | 1 TB | 4 IDE; 60 SCSI | 2 TB minus 512 bytes |
| VirtualBox 4.1.x | 256 logical cores (Windows version limited to 64) | No limit | No limit | No limit | 32 | 1 TB | 4 IDE; no limit for SATA, SCSI, SAS | 2 TB |
| Hyper-V Server 2008 R2 | 64 cores / 8 CPUs | 1 TB | No limit | 384 | 4 | 64 GB | 4 IDE; 256 SCSI | 2 TB |
| Hyper-V Server 2012 | 320 cores / 64 CPUs | 4 TB | No limit | 1024 | 64 | 1 TB | 4 IDE; 256 SCSI | 64 TB |
Note: No limit means no enforced limit. For example, a VM with 1 TB of memory cannot fit in a host with only 8 GB memory and no memory swap disk, so it will have a limit of 8 GB physically.
