There is a limitation in memory allocations for SAP HANA with asynchronous direct I/O. When you use VTE in conjunction with applications like SAP HANA that can process large numbers of direct I/O writes through the Linux AIO interface, VTE can allocate more memory than is
To limit the amount of memory that VTE consumes for AIO buffers, use the following
configuration to limit the amount of memory VTE consumed for AIO buffers:
# max_aio_memory_limit <MB>
The MB value specifies how much memory to allocate to temporary DIO buffers.
NOTE: If you do not specify a value, the default is 0, which has no memory bounding effect.
Set the option by echoing a value into the opt/vormetric/DataSecurityExpert/agent/secfs/.sec/conf/ configuration file. For example:
echo 1024 > /opt/vormetric/DataSecurityExpert/agent/secfs/.sec/conf/max_aio_memory_limit
This limits the memory consumed by AIO buffers to 1GB.
NOTE: You must restart VTE after changing any values in the configuration directory to make the changes effective.
