McDATA Products in a SAN Environment - Planning Manual

Physical Planning Considerations

•

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 automatically re-established if the

storage port is cabled through a different director or switch port.

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). Storage-level access control:

•

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.

Security Best

Practices

When implementing a enterprise data security policy, establish a set

of best practice conventions using methods described in this section

in the following order of precedence (most restrictive listed first):

SANtegrity Authentication -

The SANtegrity Authentication

feature is recommended for high-security SANs to provide

user-configurable, software-enforced password protection and

encrypted authentication for the management server, directors,

and fabric switches. These features significantly restrict access to

Fibre Channel fabric elements.
