This section contains the configuration maximums for Oracle VM. The limits presented in the following tables represent tested, recommended limits, and are fully supported by Oracle.
Table 5 Virtual machine maximums
Item | x86 Maximum | SPARC Maximum |
|---|---|---|
Virtual CPUs | 128 | Equivalent to the number of available CPUs on the server. [a] |
Virtual RAM on 32-bit guests | 63 GB | N/A |
Virtual RAM on 64-bit guests | 2 TB | Equivalent to the amount of available RAM installed on the server. [b] |
Paravirtualized Guests | ||
Virtual NICs | 31 | 768 [c] |
Virtual disks | PVM 104, PVHVM 107 | 768 [c] |
Hardware Virtualized Guests | ||
Virtual NICs | 8 | N/A |
Disks (including IDE, SCSI, CDROM and virtual disks) | 4 | N/A |
[a] On a fully configured M10 this is equal to 2048. On an Oracle M6 this is equal to 3072. On an M5 this is equal to 1536. On a T5 this is equal to 1024. Note that these maximums do not account for CPUs allocated to any other domains, such as the control domain. The hypervisor can allocate subsets of the overall CPU, memory, and I/O resources of a server to any given logical domain. [b] 32 TB on a Fujitsu M10, Oracle M5 or Oracle M6. 4 TB on an Oracle T5. A small amount of RAM is required for the hypervisor. These maximums do not account for RAM that is allocated to any other domains, such as the control domain. The hypervisor can allocate subsets of the overall CPU, memory, and I/O resources of a server to a given logical domain. [c] Total number of virtual NICs and virtual disks for SPARC is no more than the total number of available LDC (logical domains channels) of the supported SPARC T-Series server. | ||
Virtual Machine maximums assume a single virtual machine using all available resources.
Table 6 Oracle VM Server maximums
Item | x86 Maximum | SPARC Maximum |
|---|---|---|
CPUs | 160 | Equivalent to the number of available CPUs. [a] |
RAM | 4 TB | Equivalent to available RAM. [b] |
Virtual Machines | 128 | 128 per physical domain (PDOM) [c] |
[a] On an Oracle M6 this is equal to 3072. On a fully configured Fujitsu M10 this is equal to 2048. On an Oracle M5 this is equal to 1536. On a Oracle T5 this is equal to 1024. [b] 32 TB on a Fujitsu M10, Oracle M5 or Oracle M6. 4 TB on a Oracle T5. A small amount of RAM is required for the hypervisor. [c] In practice, there can be a maximum of 512 PDOMs. However, when following Oracle best practices that allocate full cores for guests, the maximum number of PDOMs are 192 on Oracle M5 and 384 on Oracle M6. | ||
Table 7 Server pool and cluster maximums
Item | x86 Maximum | SPARC Maximum |
|---|---|---|
Oracle VM Servers in a server pool (unclustered) | 64 | 64 |
Oracle VM Servers in a server pool (clustered) | 32 | N/A |
Table 8 Storage maximums
Item | x86 Maximum | SPARC Maximum |
|---|---|---|
LUNs in a storage array | 1,000 | N/A |
OCFS2 volume size | 64 TB | N/A |
Files per OCFS2 volume | 30,000 | N/A |
Virtual disk | 10 TB | Limited by hardware capacity. |
Virtual IDE drives per device | 4 | N/A |
Table 9 Network maximums
Item | x86 Maximum | SPARC Maximum |
|---|---|---|
NICs ports per network bond | 4 | 255 per bond or aggregate. |
Network bonds per Oracle VM Server | 10 | Limited by hardware. |
