http://www.hetzner.de/en/hosting/produktmatrix/rootserver-produktmatrix-px I'm looking at migrating an Internet service to the new Hetzner servers. It has to be servers with ECC RAM (the above link contains all suitable options) and is for running ZFS. The storage requirement at the moment is about 1.2TB, it's currently spread across 4 servers (2 with ZFS RAID-1 and 2 with Ext4/LVM/Linux software RAID-1). Performance is OK with the current setup but not always great. Obviously if I ordered 4*PX60 servers I would get OK performance. The old servers each have 16G of RAM and as 70% of disk IO is reads the extra RAM for cache should make disk performance good enough. One possibility I'm considering is getting 2*PX70-SSD or 2*PX90-SSD and adding 2*2TB disks to each to run ZFS with ZIL and L2ARC. Has anyone had some experience with ZIL and L2ARC on Linux? What things should I be investigating in this regard? Another possibility is to use 2*PX70-SSD and add an extra 2*480G SSDs to each so I get 1.5T of RAID-Z storage on each server. Any suggestions? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
