Storage Server

My documents on building a storage server and proxmox host.

Parts

• SuperStorage 6028R-E1CR24L

• X10DSC+ Motherboard
• AOM-S3108M-H8L RAID/HBA
• AOC-MTG-I4S quad SFP+ NIC
• 8x32 GB RAM (256g)
• 24x Seagate ST16000NM002G Exos X16 16TB 12Gb/s SAS
• 375 GB Optane SSD for l2arc/ZIL SSDPEL1K375GA01
• 3 4tb m2 SSD for Special Devices

Disk Layout

ZFS zraid2

   Zpool 
   3 - 6 disk raidz2 
   1 - 5 disk raidz2
   Special - 3 m2 flash 
   Zil - 16 GiB - optane
   l2arc -  333 GiB - optane
   Note optane is shared between Zil and l2arc

Space on this should be 15 disks of 16 tb, with redundancy or 240tb. This will leave one disk open as a hot spare.

The sata disks will be linux boot disks in a standard linux raid (maybe zfs mirror?)

SAS controller

The built in controller supports HBA mode per supermicro.
