Access control can also be implemented at the storage device as an addition or
enhancement to redundant array of independent disks (RAID) controller software.
Data access is controlled within the storage device, and server HBA access to each
LUN is explicitly limited (access is blocked by default).

Obtaining Professional Services

Planning and implementing a multi-switch fabric can be a complex and difficult
task. HP recommends that you obtain planning assistance from our professional
services organization before implementing a fabric topology.
SAN High Availability Planning Guide
Each server HBA is explicitly bound to a storage volume or LUN, and access
is explicitly authorized (access is blocked by default).
The process is compatible with OSI standards. The following are
transparently supported:
— Different operating systems and applications.
— Different storage volume managers and file systems.
— Different fabric devices, including disk drives, tape drives, and tape
libraries.
If the server is rebooted, the server-to-storage connection is automatically
re-established.
The connection is bound to a storage port WWN. If the fiber-optic cable is
disconnected from the storage port, the server-to-storage connection is
automatically re-established when the port cable is reconnected. The
connection is also automatically re-established if the storage port is cabled
through a different director or switch port.
Provides control at the storage port and LUN level, and does not require
configuration at the server.
Supports a heterogeneous server environment and multiple server paths to the
storage device.
Is typically proprietary and protects only a specific vendor's storage devices.
Storage-level access control may not be available for many legacy devices.
