HP 3Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 37)

Create Zone Group task
Zone groups allocate resources for device load balancing purposes and for selectively allowing
access to data. There are two types of zone groups:
•
Drive-bay zone groups—Group together disk drive bays, which can be chosen from across
multiple storage enclosures. Server device bays assigned this type of zone group have access
to the disk drive bays included in the zone group, as if they are directly connected to those
servers. Zoned SAS storage enclosures such as the MDS600 use drive-bay zoning. For more
information, see
“Drive-bay zone groups” (page 37) .
•
Switch-port zone groups—Group together one or more SAS ports on the switch. Server device
bays assigned this type of zone group have access to the array enclosures or tape devices
connected to the ports included in the zone group. Tape libraries and shared SAS storage
enclosures such as those using the MSA2000sa use switch-port zoning. All tape drives in a
tape device will be accessible to any server that has access to the zone group. All LUNs in
the array enclosure will be accessible to the assigned servers, unless controlled through the
storage management utility for the array enclosure. For more information, see
“Switch-port
zone groups” (page 39) .
