Physical Planning Considerations
169SAN High Availability Planning Guide
These Fibre Channel frames are then written to CD and included as part of the
data collection procedure. This process constitutes a security breach if the frame
data includes classified information.
With the full-volatility feature installed and enabled, no frame data is stored, and
the NV-RAM dump does not occur when the director or switch powers off or
fails. Although this feature limits the diagnostic information available for fault
isolation and resolution, the majority of failures are resolved without the dump
file.
CNT WAN Support
Fibre Channel-based SANs are typically implemented as isolated networks
accessible only from local servers connected through a Fibre Channel fabric.
Connectivity between devices is usually limited to about ten kilometers or fewer.
Many companies are striving to interconnect isolated SANs and consolidate
computer resources through WAN extension technology. Therefore, edge
switches deployed as part of a core-to-edge fabric often require WAN
connectivity.
This connectivity is provided by the CNT WAN support feature, included only in
software maintenance release 4.02.00. With this feature installed and enabled, an
Edge Switch 2/12 or Edge Switch 2/24 can communicate with CNT UltraNet
Edge storage routers (WAN gateways).
Element Manager Application
The Element Manager feature allows director or switch management through an
Element Manager application GUI. A director or switch is delivered with the
application enabled for a 31-day grace period. Before grace period expiration, the
application must be reactivated and enabled through a PFE key.
During the grace period, a No Feature Key dialog box (Figure 62) displays when
the Element Manager application is accessed. Click OK to close the dialog box
and open the application.
