Verify Mode Setup
VERIFY WAIT
READ aft WRITE
Verify Mode specifies when and how to perform the data verification. You can wait until the verification
to be done with [Verify Wait] mode. If you’d like to do the writes without verifying you can specify [No
Verify] mode.
Also, you can choose to read the data off the disk after it has been written from cache when a read
request takes place [READ aft WRITE], or you can choose not to verify it at all after the write [NO READ
aft WRT]
Parameter Function Memo
VERIFY
WAIT
The Write command cannot be completed at the time data written
into cache. It has to wait till Write and Verification command
completed.
Default
NO VERIFY
There is no verification operation when doing Write & Verify
under such mode. A simple write will be executed. Verify
command is not affected by this setting.
READ aft
WRITE
Instead of Verify command, sometimes READ command usually
follows a series of Write command to compare and verify the
written data. It is meaningless if cache data is used upon READ
command received. This parameter is to clean up cache data
after WRITE, and force data to be read from disks when READ
command is received.
Default
NO READ aft
WRT
This mode assumes write operation can be continued when data
is into cache before moving to disk. And also it assume there is
no more than one drive failed at the same time under RAID-3/5
setting. The data written into cache becomes effective
immediately.
