Garbage Collection Threshold
(GC)
GC starts eviction and frees
write blocks when the
{gc_threshold%} of write blocks
are free.
The default threshold value is
30%.
If GC already triggered, the GUI
will pop up a message.
Date Age Timer
Updates the maximum data_age Its value is in terms of
of each write_block. Data age is milliseconds with a default value
calculated from the time the data of 500 milliseconds.
is first written after this interval,
the complete data in the
write_block is flushed.
GC Trigger Initiates
Initiates Garbage Collection
(GC) outside of the threshold
parameter set by the Threshold
GC function.
Release Reserve/Recreate
Reserve
For deduplication nodes:
•
•
For Release 5.0.1.2a and
later, if a disk-full scenario
occurs, the Release Reserve
function releases 10GB of
the Volume Group so that
the writing and deleting data
can continue.
Recreate Reserve reinstates
the 10GB Reserve LV.
Reserve LV can only be
recreated if the physical
space availability is greater
than 50 GB. Before
attempting to recreate a
Reserve LV, check the
available space on the
Volume Group using the
GUI (see Release
Reserve/Recreate Reserve
later in this section).
•
A 10 GB Reserve LV is
factory set.
•
The default button on a
deduplication node is
Release Reserve.
•
Once the reserve is released,
the Recreate Reserve
button is displayed in its
place.
Note
If the Reserve LV was
released prior to the
upgrade to OS v5.0.1.3,
then the Reserve LV will
NOT be automatically
created by the WSP
package upon install. In
this case, create the
Reserve LV again
manually after the WSP
install by logging in as
Super User.
Setting the Garbage Threshold
Garbage Collection (GC) starts eviction and frees write blocks when the {gc_threshold%} of write
blocks are free. To set the GC, do the following:

Step 4
Select the GC Threshold percentage from the drop-down list.
Recreate Reserve/Release Reserve
Note
•
A 10 GB Reserve LV is factory set.
•
The default button on the deduplication node is Release Reserve.
•
Once the reserve is released, the Recreate Reserve button is displayed in its place.
If the Reserve logical volume (LV) was released prior to the upgrade to OS v5.0.1.3, then the Reserve
LV will NOT be automatically created by the WSP package upon install. In this case, create the Reserve
LV again manually after the WSP install by logging in as Super User.
Reserve LV can only be recreated if the physical space availability is greater than 50 GB. Before
attempting to recreate a Reserve LV, using the GUI, check the available space on the Volume Group by
doing the following:
Step 1
Select SSR Configuration > VG/Node Settings.
The VG/Node Settings window appears.
Step 2
Right-click the deduplication Volume Group where the Reserve LV is to be created.
Step 3
Select Physical Space from the menu.
The Logical Space vs. Physical Space graph appears.
To recreate or release a Reserve LV:
Step 1
Select Support > Acceleration Stats.
The Acceleration Stats window appears.
Step 2
(For SSR only) From the drop-down list, at the top of the window, select the deduplication SSN for
which the Reserve LV is being created.
Step 3
Click Release Reserve/Recreate Reserve.
Step 4
If recreating a Reserve LV, a 10 GB Reserve LV is created by default.
