Hello Community members and Unity experts,    I am new to unity and I have the following two questions   1. I believe the unity SP Controllers do come with 2 embedded  SAS Ports and 4 10 GB ports (when using ISCSI). When does it make sense to add an additional module for 10 GB ports?     2. Question about Pools does it make sense to have 1 POOL  when using a combination of FLASH and SAS drives? Raid 5 Flash with 5 drives and Raid 5 SAS with 18 Drives (2 spares)?   Thank you Kindly   Peter
