Hi,

2011/3/24 Freddie Cash <fjwcash@gmail.com>:
> The hardware is fairly standard fare:
> =A0- SuperMicro H8DGi-F motherboard
> =A0- AMD Opteron 6100-series CPU (8-cores @ 2.0 GHz)
> =A0- 8 GB DDR3 SDRAM
> =A0- 64 GB Kingston V-Series SSD for the OS install (using ahci(4) and

> =A0- 3x SuperMicro AOC-USAS2-8Li SATA controllers with IT firmware

> =A0- 12x 1.0 TB Seagate 7200.12 drives (2x raidz2 vdev)
> =A0- 6x 0.5 TB WD RE3 drives (1x raidz2 vdev)

just for info, sun recommend 1 Gb of RAM per Tera of data.
i see here ~ 16 To of available data, so i would recommend 16 Gb for
arc_size and 24 or 32 Gb for the host.
