22 Sun StorageTek 2500 Series Array Hardware Installation Guide • September 2009
Disk Drives
Disk drives for the Sun StorageTek 2500 Series Array have three components:
■ Hard drive
■ Hard drive carrier
■ Adapter card for connecting the disk drive to the mid-plane
The disk drives can be Serial Advance Technology Attachment (SATA) disk drives,
Fibre Channel (FC) disk drives, or SAS disk drives.
Controller trays or drive expansion trays hold up to 12 disk drives, for a maximum
of 48 disk drives in a storage array. To reach the maximum of 48 disk drives, the
storage array must consist of one controller tray and three drive expansion trays.
Access to disk drives is from the front of the tray.
Refer to the storage array release notes for supported drives.
Disk drives can be mixed, provided you adhere to these additional rules:
■ Use the same drive types within a virtual disk
■ Assign hot spares to cover any disk drive failure
