Supported disk types and disk shelves
Disk types that the
gateway supports The gateway supports the following disk types:
◆
FC (Fibre Channel)
◆
SATA (Serial ATA)
Note
Only AT-FCX modules shipped in December 2005 or later are supported. If
you are unsure whether your module is the correct version, see the Data
ONTAP
High Availability Configuration Guide or the Data ONTAP
Active/Active Configuration Guide for the procedure for checking the
version of the AT-FCX module.
Native disk shelves
that the gateway
supports Gateway models that support disk shelves support the same disk shelves and the
same disk types per I/O module on the shelves as the equivalent filer models. See
the appropriate hardware and service guide and Interoperability Matrix on the
IBM NAS Support site for more information.
Note
The gateway requires the software disk ownership scheme, which uses persistent
reservations. Only disk shelves that support software disk ownership can be used
with gateways. You might also see the disk ownership scheme referred to as
SANOWN or LUN ownership.
