Default Write Algorithm Recommendations
For performance reasons Pegasus recommends that users choose the Lazy Write setting. As indicated, this feature offers signifi cant performance and disk usage advantages.
Users however, should keep in mind that the nature of caching does expose the system to the possibility of data loss if the server should crash prior to the data being committed to storage disk. InveStore min imizes this risk by periodically committing data to storage auto matically.
Note: If an InveStore user encounters any PC sub-system or library hardware problems, it is recommended that the Default Cache Write Algorithm be changed to Write Through until the PC or library problems are resolved and stable operation of the storage server is insured.
