Storage subsystem port support, by model

LUN support on storage system ports

The following table shows the type of LUN support provided for ports and host groups, by storage subsystem model. A host group is a property of a port.

Storage subsystem model	Port support information
XP512, XP48	Supports only up to a maximum of 256 LUNs per port. No support for host groups.
XP1024, XP128	Supports 256 LUNs per port. However, when LUN security is enabled on the port, a maximum of 512 LUNs is supported on the port. To achieve the 512 LUNs per port, create at least two host groups per port. All LUNs can be divided among the host groups for the port. A maximum of 256 LUNs per host group can be configured. A maximum of 128 host groups can be created for each port. Host groups are created within each port. The same gFiler HBA WWN cannot be registered within multiple host groups.
XP12000	Supports 1,024 LUNs per port, with or without LUN security enabled. A maximum of 256 host groups can be created for each port. A maximum of 1,024 LUNs per host group can be configured. However, if more than one host group exists in a port, the 1024 LUN limit for that port can be divided among those host groups.
