Notes
- The 3.5V batteries are not field replaceable.
- Set SW1 to BAT when the board is installed. Software will not
initialize Prestoserve unless battery backup is enabled.
- Set SW1 to +5V when the board is removed and cache data does not need
to be saved.
- Cache data is cleared from memory when SW1 is set to +5V for more than
five minutes.
Application Notes
- Do NOT accelerate the root file system.
- SBus Prestoserve accelerates SBus and VMEbus disk controllers.
- The SS600MP supports one VMEbus or one SBus Prestoserve.
- The SS600MP minimum requirements are SunOS 4.1.2 and Prestoserve 2.3.
- Install Patch
101714-01
for Prestoserve 2.4 and 2.4.1.
- The Prestoserve hardware design is not compatible with 64-bit DVMA.
Disable 64-bit DVMA when Prestoserve is used with Ultra 1 Model 170E,
Ultra 2, and SunSwift. Refer to BugID 1224649. Add the following to
/etc/system:
- set fas:fas_enable_sbus64 = 0
