What's New in xiRAID Classic 4.2.0

Performance Improvements

Multiple performance enhancements have been implemented to significantly imrove write speeds using a block size of 512 KB. When the RAID operates in a normal state, the performance improvement is approximately 27% compared to version xiRAID Classic 4.1.0. This improvement increases to around 31% when the RAID is in a degraded state.

Reserved Memory

Using reserved memory in RAIDs improves performance for workloads that require random access to small data chunks. This performance improvement becomes even more significant when the RAID is operating in a degraded state.

By default, all new RAIDs will be created with 2048 MiB of reserved memory. Reserved memory will not be created for RAIDs created prior to updating to xiRAID Classic 4.2.0. To allocate reserved memory for existing RAIDs, execute the following command:
# xicli raid modify -n <raid_name> -mp 2048

where <raid_name> is the name of the RAID for which to allocate reserved memory and 2048 is the amount of memory to allocate, in MiB. Note that the specified amount must not exceed the available system memory minus 1 GiB, leaving at least 1 GiB free. For more details about changing RAID parameters, see this topic.
