ahab666 Posted January 17 Share Posted January 17 (edited) Hi gurus and experts, I have the opportunity to speed up my server a bit, so I'd like to ask you some NOOB questions, 1. My HDD HBA card has 4x4 SATA 6 connections, with 4 connectors on the card and 16 endings for the individual HDDs. How important is it to keep the HDDs on the same port (LUNs)? 2. In theory, I can add 3 NVMs, but the connection speeds and lane counts are different ! 2 of them have an PCie gen 4 port, the third one is PCIe gen 3. Will the slower one interfere with the 2 faster ones ? Either by slowing them down, or might it even cause timing problems ? 6TB of cache would be nice, but I can easily live with 4 (2x2) TB. Does splitting them up in 2 pools, like one exclusively for docker apps the 2 faster ones as mirrors Raid 0 ? and the slower one as input buffer ? 3. Can one of name me the terminal commands for checking on the integrity of the data HDDs (XFS) superblocks and all that jazz b4 I start the disassembly and re-assembly of my server. Aaaah and I need/will replace 1 Data drive as well as the second Parity disk. Anything else to be aware of ? thx for reading and cheers - ahab Edited January 18 by ahab666 update Quote Link to comment
