Physical Planning Considerations
166 SAN High Availability Planning Guide
Each port expansion kit includes eight SFP optical transceivers, upgrade
instructions, and a feature key that enables the added port capacity through the
Element Manager application.
SANtegrity Binding
SANtegrity Binding is a feature that enhances data security in large and complex
SANs that have numerous fabrics and devices provided by multiple original
equipment manufacturers (OEMs). This feature allows or prohibits director or
switch attachment to fabrics (fabric binding) and Fibre Channel device attachment
to directors or switches (switch binding). The SANtegrity binding feature
includes:
■ Fabric binding — Using the fabric binding feature, an administrator allows
only specified directors or switches to attach to specified fabrics in a SAN.
This provides security from accidental fabric merges or potential fabric
disruption when multiple fabrics segment because they cannot merge. This
feature is managed through the HAFM Manager application.
■ Switch binding — Using the switch binding feature, an administrator allows
only specified devices and fabric elements to connect to specified director or
fabric switch ports. This provides security in environments that include a
large number of devices by ensuring that only the intended set of devices
attaches to a director or switch. This feature is managed through the Element
Manager application.
Enterprise Fabric Mode
Although Enterprise Fabric Mode is not a keyed feature, it is integral to
SANtegrity Binding operation. Enterprise Fabric Mode must be enabled through
the HAFM Manager application before fabric binding and switch binding can
operate. Enterprise Fabric Mode also enables the following parameters:
■ Rerouting delay — If a fabric topology changes, directors or switches
calculate a new least-cost data transfer path through a fabric, and routing
tables immediately implement that path. This may result in Fibre Channel
frames being delivered to a destination device out of order, because frames
transmitted over the new (shorter) path may arrive ahead of previously
transmitted frames that traverse the old (longer) path. When enabled, the
rerouting delay parameter ensures that frames are delivered through a fabric
in the correct order.
