EMC Centera Disk Option › Configuring the Centera Access Server › Reusing Buffers

Reusing Buffers

After the Centera server accesses all buffers allocated to it and needs to reuse a buffer, it does the following:

1. Accesses the least recently-accessed buffer.
2. Reads the NREAD number of blocks and adjusts the blocks to make sure it does not re-read an already buffered block.
3. Frees previous blocks when a forward search is detected to prevent forward search users from taking over all buffers.
