I have both EVDS and EARS 2TB green drive. And I have to say they are not good to build storage servers.
EVDS has compatibility issue with my supermicro appliance. it will hang when doing huge data send or copy. from IOSTAT I can see the data throughput is stuck on green disks with extremely high wait time. for EARS drives, they are ok running opensolaris but veryvery poor performance handling small files. I'm doing SVN via NFS share and it takes triple time CO a repository compare to NEtapp FAS960. but the issue could be resolved by adding SSD as log device. notice that, green disk seek time is 15ms and normal 7200RPM disk is around 8.5ms. I'll try the link provided by Christian to see if it can help the performance. anyway, I've decided to use seagate 7200.11 which is big enough and fast. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
