Gdps Continuous Access Synchronous Z Compatible Xrc Matrix - HP XP P9500 User Manual

Table 39 P9500 response characteristics to failure conditions (continued)
Failure condition
* When one side of the MCU cache is blocked, duplex Continuous Access Synchronous Z pairs are not affected, but
pending duplex Continuous Access Synchronous Z pairs are suspended. Suspending Continuous Access Synchronous
Z pairs with pending duplex status provides additional protection in the unlikely event of a cache failure.
