Hello,
Long time follower of the community. I have not posted often. I was hoping to get a sanity check on my configuration, as well as any feedback. I don't have any performance issues at the moment, but I'm always looking to Optimize. This is my current home setup.
Base Storage Head
-Dell PowerEdge T420
-TrueNAS Core 12.0 u4
-2 x Intel E5-2430L-V2 Processors
-80GB/RAM
-Onboard SATA (for 6 Internal Drives)
-LSI 9207-8i (8 Internal Hot-Swap Bays)
-LSI 9207-8e (External 24 Slot Shelf... MD1220)
-Broadcom BCM57810S Dual Port 10G CNA
TrueNAS Configuration
-Pool A (Backups via NFS)
-2 x 1TB 7200RPM SATA Drives combined into a mirrored vDEV
-1 x 40G Intel 320 SSD as SLOG
-Backups runs very well, easily hitting 150MB/sec via NFS using Veeam
-Pool B (Nearline Storage)
-8 x 2TB 7200RPM Self Encrypting SAS2 Drives split into 4 x Mirrored vDEV
-1 x 200G Intel DC S3700 SSD as SLOG
-Primarily Serves as Datastore in vSphere using iSCSI for Video Storage and some VMs.
-Sync-Always enabled
-Pool C (10K SAS Storage)
-13 x 600G 10KRPM 2.5" SAS Drives split into 6 x Mirrored vDEV with 1 Spare
-1 x 200G Intel DC S3700 SSD as Slog
-Primarily Serves as Datastore for VM Storage via iSCSI
-Sync-Standard Enabled
-Pool D (SAS SSD Storage)
-5 200G 2.5" SAS SSD (High Endurance w/Power Protection) split into RAID-Z1 with 1 spare.
-No SLOG
-Primarily Serves are Datastore for VM Storage via iSCSI

Thoughts
- The SLOG in Pool C is wasted.
- My ARC Summary doesn't necessarily show a benefit for an L2-Arc in my use case. One alternative I thought about was pulling the SLOG from Pool A and B, putting the 2 x Intel S3700s together and doing a Mirrored Meta-Data for Pool-B to help offset the slow drives. Backups via NFS will be fine without it I reckon.
- Pool D
- I do realize I'm chewing up Endurance on the SSD's. I needed lowish seek time and more space than mirrored vDev's would give me. Medium-term plan is to get 4 more of the same SSD's and do mirrored vDEVs for performance.
