4.4.7 Setting the ES3000 Capacity
Operation Scenarios
The ES3000 write performance, especially the random write input/output operations per second
(IOPS) of small data blocks, depends on the capacity. A smaller capacity ensures a higher random
write IOPS of small data blocks. You can set the ES3000 capacity within a specified range.
NOTICE
l
The capacity setting operation cannot be interrupted. If the operation is interrupted, you need
to set the capacity again. Otherwise, the SSD device cannot be properly used.
l
Before setting the capacity, migrate all virtual machines from the ES3000 and ensure that no
host is accessing the ES3000.
l
Back up all required data before setting the capacity. This is because all data on the ES3000
will be lost after the capacity is set. Use the command with caution.
