Hi, First thanks for everyone who responded, very helpful. One 2 more questions/clarifications: 1. As many mentioned 2008/3008 LSI HBA I searched (for lsi sas hba 24 ports) and found many but with lsi i/o controller other than 2008/3008, for example 3224)..it seems 2008/3008 are more popular in 8port hba cards. 2. I got That as much ram is better however I saw almost no docs / recommendations and how to estimate CPU.. So I need more clarification on how to size CPU with the following configurations ZFS for raidz2, all without dedup: A) lz4 compression. B) encryption (I must say I still not quiet know what are my options) C) A+B Thanks, Sami =D7=91=D7=AA=D7=90=D7=A8=D7=99=D7=9A =D7=99=D7=95=D7=9D =D7=95=D7=B3, 21 = =D7=91=D7=93=D7=A6=D7=9E=D7=B3 2018, 12:33, =D7=9E=D7=90=D7=AA Ben RUBSON <= ben.rubson@gmail.com>: > > On 13 Dec 2018, Sami Halabi wrote: > > > > 2.
