Cache Flush Modifier
Valid values for the cache flush modifier are listed in the following table.
Value Description
Immediate Data is flushed as soon as it is placed into the
cache.
250 Data is flushed after 250 ms.
500 Data is flushed after 500 ms.
750 Data is flushed after 750 ms.
1Data is flushed after 1 s.
1500 Data is flushed after 1500 ms.
2Data is flushed after 2 s.
5Data is flushed after 5 s.
10 Data is flushed after 10 s.
20 Data is flushed after 20 s.
60 Data is flushed after 60 s (1 min.).
120 Data is flushed after 120 s (2 min.).
300 Data is flushed after 300 s (5 min.).
1200 Data is flushed after 1200 s (20 min.).
3600 Data is flushed after 3600 s (1 hr).
Infinite Data in cache is not subject to any age or time
constraints. The data is flushed based on other
criteria that are managed by the RAID controller
module.
Cache Without Battery Enabled
Write caching without batteries enables write caching to continue if the RAID controller module batteries
are completely discharged, not fully charged, or not present. If you set this parameter to TRUE without an
uninterruptible power supply (UPS) or other backup power source, you can lose data if the power to the
storage array fails. This parameter has no effect if write caching is disabled.
Modification Priority
Modification priority defines the amount of system resources that are used when modifying virtual disk
properties. If you select the highest priority level, the virtual disk modification uses the most system
resources, which decreases the performance for host data transfers.
