Hi, Sergey. My be following information will be useful for you. We use solaris as HA NAS in following configuration:
DATA_DISKS: HUC101818CS4204 / HUH728080AL5204 SLOG: PX04SHB020 / PX05SMB040 / HUSMH8020BSS204 (PX04SHB020 has best performance https://dhelios.blogspot.ru/2016/11/ssd-hgst-husmh8020bss204_11.html) L2ARC: HUSMH8080BSS204 / PX05SMB080 Servers: 2 x Cisco UCS 240M4 ( 2 x E5-2697A, 768gb ram, 3 local hard disk for OS, 2 x UCSC-SAS9300-8E, 2 x Intel X520 Dual Port 10Gb SFP+ Adapter) JBODS: 216BE2C-R741JBOD - for SFF disks SC847E2C-R1K28JBOD - for LFF disks We have two HA variant: 1) Solaris 11.3 + Solaris Cluster 4.3 (for VMware) 2) OmniOS + RSF-1 (as Cinder for Openstack) If you need some additional info, I'll be glad to share any information that I have. ср, 27 сент. 2017 г. в 22:39, sergey ivanov <serge...@gmail.com>: > Hi, > as end-of-life of r151014 approaches, we are planning upgrade for our > NFS servers. > I'm thinking about 2 servers providing ISCSI targets, and 2 another > OmniOS servers using these ISCSI block devices in mirrored ZPOOL > setup.
