Sc847 36 drive config. Wd RE3 1tb drives. Areca and lsi hba. 3 or so drives would completely hang under any kind of decent load.
Replaced with lsi 1068 and chenbro sas espanders and replaced the supermicro backplane with the -A version (direct port) and its been riPping along for well over a year. We replaced the 3gb backplane 2x and exact same failures. Supermicro refuses to concede a problem exists. The smicro board is total sh*t despite using an lsi expander chip. We are building a backblaze like bulk storage setup. Can't find a dense chassis like sc847 and hoping to convince supermicro to create -a version of the jbod. Hoping I can convince lsi/netapp to sell me DS6600 tray or nexsan E60x or DDN S26000 without their gold plated drives. Or just don't buy WD drives. Only hitachi/ibm or seagate NL SAS are any good. God's work is never done; neither apparently VDOTs. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
