Dear List,
We have X4-2 Half Rack with 20TB flash cache with database size 8TB. I am very
reluctant to enable flashcache compression as the size of the database is half
of flashcache, but Oracle says enabling flashcache compression is a best
practice. Every code execution need time, even though FC is implemented in
hardware level compression, still I believe, there will be a penalty. In this
scenario, enabling flashcache compression is a wise idea? Any one got
falshcache I/O performance test results with compression and with out?
Note: License is not an issue as we have Advanced Compression license.
Thanks in advance,
Thomas Saviour
